2Amines and Amides
Amines a class of organic compounds of
nitrogen that may be considered as derived from
ammonia (NH3) by replacing one or more of the
hydrogen atoms -derivatives of Ammonia -number
of "R" groups varies and is attached to
Nitrogen Amides the organic functional group
characterized by a carbonyl group (CO) linked to
a nitrogen atom (N), contain carbonyl Carbon
attached to Nitrogen, so most "R" groups on
Nitrogen is 2. Note Amides in Chap 11, will
cover now!

9CAFFEINE
10What is Caffeine?
- Caffeine (C8H10N4O2), or trimethylxanthine,
- is a
- ?CNS stimulant
- ? cardiac muscle stimulant
- ?respiratory system stimulant
- ? mild diuretic.
11History of Caffeine
- Caffeine is one of the worlds most widely used
drugs. It was first extracted from coffee in
1821. It originated in Ethiopia and by the
fourth century AD it was introduced to Arabia and
the rest of the east. Nomads saw the effects
that it had on animals and how it gave them extra
energy. Therefore it was used in religious
ceremonies so that people could stay up all night
and pray. - Coffee was introduced to the Europeans in 1573
- Tea was introduced in 1657 and became very
popular. - Chocolate milk was introduced in Switzerland in
1873.
12What is Caffeine?
- Caffeine is medically known as trimethylxanthine
- It is a alkaloid and its chemical formula is
C8H10N4O2 - When isolated in pure form its a crystalline
powder and tastes bitter. - It is used as a cardiac stimulant or a mild
diuretic which flushes out the system - Many people use this to feel a boost of energy
or used to stay awake longer -
- This is the chemical
- structure of caffeine
-

13How Caffeine Works
- This drug causes a chemical change in the brain
in two ways - First, caffeine mimics adenosine and binds to all
other adenosine receptors in your brain. This
prevents the real adenosine from doing its job
which happens to be the slowing down of nerve
impulses and the cause of drowsiness. - Second, caffeine also increases the dopamine (a
neurotransmitter which activates the pleasure
center) in your brain? improves the well-being
and mood. This is also one reason why this drug
is so addictive. - Caffeine is mainly found in beans, leaves,
fruits, and over 60 plants where it acts as a
pesticide to kill insects.
14An Addictive Drug
- 90 of Americans consume caffeine in one form or
another every day - More than ½ of American adults consume more than
300mg of caffeine every day - It is addictive because it uses the same
mechanism that amphetamines such as cocaine and
heroine use to stimulate the brain - These drugs close the blood vessels in the brain
so that the body cannot go to sleep, releasing a
rush of adrenaline into the body.
15Withdrawal of Caffeine
- Many people that consume caffeine on a daily
basis will experience these withdrawal effects - Headaches
- Irritability
- Nervousness
- Restlessness
- Insonmia
16Caffeine Products
- Coffee 80-135 mg of caffeine
- Decaf Coffee 2-3 mg of caffeine
- Espresso 100 mg of caffeine
- Coke/Diet Coke 45.6 mg of caffeine
- Mountain Dew 55 mg of caffeine
- Chocolate 28 mg of caffeine
- Tea 40-60 mg of caffeine
17Where is Caffeine Found?
- Caffeine is present in coffee, tea, soft drinks,
chocolate, and kola nuts. - Colas contain relatively low amounts of caffeine,
but also contain other alkaloids that can enhance
caffeine reactions. - Coffee tends to work best for long-lasting
alertness.
18How Does Caffeine Work?
- Nerve cells mistake caffeine for adenosine, a
hormone that causes drowsiness. So caffeine
binds to adenosine receptors. - One of the mechanisms that caffeine addiction,
cocaine addiction, and heroin addiction share, is
that they block an adenosine's ability to slow
the nerve cells' activity in preparation for
sleep, and instead increase the speed of their
activity and of the neuron firing in the brain.
The caffeine causes the blood vessels in the
brain to constrict, because it has blocked the
adenosine's ability to open them to allow sleep.
The ability of caffeine to close the blood
vessels is why many pain relievers contain
caffeine. If a person has a vascular headache,
the caffeine in the medicine will shut down the
blood vessels, thus easing the pain. - As a result, nerve cells dont take in adenosine
and, therefore, begin to speed up. - Brain activity is increased, which causes the
pituitary gland to release adrenaline. This
boosts alertness. - Caffeine also stimulates the hormone dopamine,
which makes one happy. - This is why caffeine is addictive.
- Also, it constricts blood vessels in the brain
19The Benefits of Caffeine
- Caffeine is a vasoconstrictor, so it can
sometimes relieve headaches caused by dilated
blood vessels. - It also promotes alertness and makes one feel
happy.
20Downsides to Caffeine Use
- After a caffeine-induced adrenaline high, lows
occur causing tiredness and depression. - Such lows cause one to consume more caffeine and
to eventually become caffeine-dependent. - Caffeine has a half-life of 6 hours. If it is
consumed late in the day, it hinders deep sleep
as adenosine (essential for sleep) is blocked.
21Caffeine as Medication
- Caffeine can be taken in powder and tablet form
to promote alertness. - Yet caffeine pills should only be taken for short
periods of time. - Some symptoms of a caffeine overdose include
- tremors, trouble sleeping, dizziness, rapid
heartbeat, and nausea.
22Some Side Effects of Normal Caffeine Use
- Caffeine consumption in large amounts has been
shown to decrease bone mineral density. - A caffeine-dependent cycle can occur, which
brings with it severe headaches if a person does
not get caffeine. - Deep sleep can be affected.
23Side Effects for Mothers
- During pregnancy, large and daily doses of over
300 mg (equal to 3 cups of coffee) may hinder the
development of a fetus or promote miscarriages. - Caffeine use while breast-feeding may make an
infant jittery.
24Effects of Amphetamines
Increased talkativeness Increased
aggressiveness Increased breathing
rate Increased heart rate Increased blood
pressure Reduced appetite Dilated
pupils Visual hallucinations
25Side Effects
Head aches
Stunted growth
Insomnia
Nervous
Coma
Hallucinations
26Long-Term Effects
There are many long term effects due to
amphetamines. Mental illness like paranoid
schizophrenia, malnutrition, violence and
aggression, infections due to IV injections, and
blockage of blood vessels are all long-term
effects of amphetamines.
27Diet Pills
-CNS Stimulant, effects brain spinal cord
-Amphetamines are used as diet pills because they
raise glucose level in blood. Body doesnt need
food, person doesnt eat because stomach feels
full because the glucose is high.
(note amphetamines are not a safe or effective
way to lose weight.)
28Closing Notes
The effects of using amphetamines can be deadly.
Amphetamines are an addictive drug, can cause
serious damage to ones health. The most severe
effect of amphetamines are popping of the blood
vessels in the brain, or heart failure.
29Methylphenidate (Ritalin)
- Website
- Methylphenidate is a medication prescribed for
individuals (usually children) who have
attention-deficit hyperactivity disorder (ADHD),
which consists of a persistent pattern of
abnormally high levels of activity, impulsivity,
and/or inattention that is more frequently
displayed and more severe than is typically
observed in individuals with comparable levels of
development. - Methylphenidate is a central nervous system (CNS)
stimulant. It has effects similar to, but more
potent than, caffeine and less potent than
amphetamines
30How Ritalin works
- Methylphenidate works by affecting some of the
natural chemicals that are found in the brain. In
particular, it increases the activity of
chemicals called dopamine and noradrenaline in
areas of the brain that play a part in
controlling attention and behaviour. These areas
seem to be underactive in children with ADHD. It
is thought increasing the activity of these
chemicals improves the function of these
underactive parts of the brain. We still dont
fully understand how stimulants work in children
with ADHD, and they dont work for everyone. But
they can be very useful at helping some children
to learn to control their behaviour.
31More Ritalin info
- Doctors aren't really sure how Ritalin works on
ADHD kids. Ritalin is a stimulant medication.
When you consider that kids with ADHD are already
over-stimulated, it is hard to understand how a
stimulant drug will help to calm them down.
Doctors think it has to do with some of the
neurons in the brain. Instead of being balanced
as they should, some of the neurons work overtime
while others are under worked. For some reason,
Ritalin stimulates the neurons that aren't
working as they should. The area of the brain
that tells one when to pay attention to certain
activities and to ignore other ones is "lazy" in
ADHD sufferers . Ritalin stimulates those neurons
so that the child can pay attention and focus on
his activities.
32Tranquilizers
-all have 7 membered ring containing 2
Nitrogens -CNS depressants -Valium (diazapam)
most common/Librium
33TRANQUILIZERS
- Tranquilizers are divided into a Major
Tranquilizer and Minor Tranquilizer group. - Major Tranquilizers include phenothiazines,
indoles, thioxanthenes, butyrophenones,
piperazine compounds, and piperidine compounds.
Trade names include drugs such as Thorazine,
Haldol, Clozaril and Risperdal. These drugs are
referred to as Neuroleptics and are most commonly
prescribed as anti-psychotics. This type of
tranquilizer is not widely abused. - Minor Tranquiliers are the more common of the
tranquilizers. These include the Benzodiazepines,
known by trade names such as Valium, Xanax,
Serax, Ativan, Klonopin, Librium and Tranxene.
There are also combination drugs such as Librax.
These drugs are very commonly prescribed as
anti-anxiety drugs, or anxiolytics. They are
often referred to as Sedative/Hypnotics. They are
central nervous system depressants with specific
sites of action. Slang references to these drugs
include Libs, Tranks, Benzos, and Vees. - The primary route of administration for these
medications is oral, swallowed as a tablet,
capsule, or liquid. They are also available in
solution form for intravenous use.
34Effects of Tranquilizers
- The minor tranquilizers induce a feeling of calm
and relaxation. Commonly used pre-surgery to
relax the patient. Depending on the medication
and dosage this can range from feelings of mild
euphoria to states of drowsiness, confusion, and
lightheadedness. Effects can include hostility,
blurred vision, hallucinations, lethargy,
headaches, memory loss, disorganized thinking,
and irritability. Other common effects include
impaired motor function, dry mouth, nausea,
vomiting, and sweating. Certain Benzodiazepines,
including Valium, can produce toxic reactions
when combined with alcohol. - The Benzodiazepines (Minor Tranquilizers) can be
addictive even at prescribed dosages if the
medication is administered for long periods of
time. The withdrawal process can be painful and
even life-threatening with some of the
Benzodiazepines. Physical withdrawal symptoms can
include general pain, stomach cramps, diarrhea,
flu-like symptoms, and heart palpitations. There
is also the possibility of seizure with certain
medications. The withdrawal can also produce
psychosis, hallucinations, delusions, paranoia,
and depression.
35Sleeping Pills
36History
- Common type of sleeping pills antihistimines,
over the counter sleeping pills that contain
diphenhydramine (benadryl, etc) - Barbiturates were used to treat symptoms, but
stopped being used because side effects mirrored
drunkenness (slurred speech, hangover, etc) - Benzodiazepines presently used types of pills
- Most commonly abused drug because of easy access
37Chemistry
- Effect the GABA gating system, central to
thoughts/brain activity - Make chloride channel in middle of GABA open so
chloride can flow through - Chloride keeps cells from being activated so
system is quieted, cant promote sleep - CNS depressant
- Suggested doses no more than 10 mg (adult), 5 mg
(elderly)
38Uses of Sleeping Pills
- Used as sedatives and tranquilizers
- Treat anxiety help with short-term sleep
problems - Help with insomnia, jet lag
- Symptomatic cure, not causal
- Should only be used for brief periods of time (2
weeks max) - NOT to be used for sleep apnea
- (obstruction of throat/delay of brain signal
reminding body to breathe), need to be able to
wake up
39Side Effects
- Physical dependence- body adapts to the presence
of the drug - Hallucinations, sleep walking, sleep driving, etc
- Withdrawal symptoms may include
- anxiety
- restlessness
- insomnia
- irritability
- gastrointestinal problems
- loss of appetite
- trembling/weakness
- increased sensitivity to light, sound, smells
40Barbiturates
-barbituric acid 1st one and a cyclic
amide -physiological effect of being a CNS
depressant -act as sedatives in small doses or
induce sleep (general anethesia-see next slide
for current drugs used in general anethesia) in
large doses (see specific examples in
text) -synergistic effect with othe CNS
depressants such as alcohol
41Current General Anesthesia
- induction agents
- For 50 years, the most commonly used induction
agents were rapidly acting, water-soluble
barbiturates such as thiopental, methohexital,
and thiamylal. These drugs are not commonly in
use today. - Propofol, a nonbarbiturate intravenous
anesthetic, has displaced barbiturates in many
anesthesia practices. - The use of propofol is associated with less
postoperative nausea and vomiting and a more
rapid, clear-headed recovery. - In addition to being an excellent induction
agent, propofol can be administered by slow
intravenous infusion instead of vapor to maintain
the anesthesia. - Among its disadvantages are the facts that it
often causes pain on injection and that it is
prepared in a lipid emulsion, which, if not
handled using meticulous aseptic precautions, can
be a medium for rapid bacterial growth. - Anesthesia can also be induced by inhalation of a
vapor. This is how all anesthetics were once
given and is a common and useful technique in
uncooperative children. It is reemerging as a
choice in adults. Sevoflurane is most commonly
used for this purpose.
42What are they?
- Barbiturates are CNS depressants. There are over
2,000 known barbiturates. - Barbiturates are some of the most addictive
drugs. They are often used to substitute for
alcohol because similar effects are produced.
43Physiology Of Barbiturates
- Barbiturates are depressants. They are used as
medication for the treatment of mental illnesses,
epilepsy, insomnia, and any type of hyper
excitement. - They reduce cranial pressure and
- They also induce sleep and subdue pain.
- Their main uses in this era is a general
anesthetics they are very effective, they will
put anyone to sleep in ten seconds. - They work by enhancing the GABA neurotransmitter
by bind to the receptor for GABA. Barbiturates
dissolve easily in fat.
44Barbiturates History
- In 1864, Adolph von Baeyer added urea to diethyl
malonate in the presence of ethoxide ion. The
result of this was a cyclic compound that Baeyer
called barbituric - It was later discovered that certain derivatives
of barbiturate acids , such as Pentothal,
Pentobarbital, and Sectobarbital have powerful
psychological effects.
45When Barbiturates are prescribed
- Treatment of disorders such as insomnia, anxiety,
tension, and epileptic seizures. - 50 mg is a normal dosage that may be prescribed
but because rapid tolerance may occur, up to ten
times this amount may be needed to produce a
similar effect.
46Immediate Effects appear rapidly and may last
from hours to days
- Sleepiness
- Slurred speech
- Trouble walking, balancing, etc.
- Emotional Instability
- floating sensation
- Slowing of heartbeat
- Shallow breathing
- Sense of relaxation
- Reduced attention span
47Long Term Effects
- Increased aggressiveness
- Severe depression
- Physical dependence
- Withdrawal reactions
- Vision problems
- Chronic tiredness
48Side Effects
- Skin rashes
- Nausea
- Dizziness
- Increases blood pressure, heart rate, breathing
rate, and body temp. - Heart attacks, strokes, and respiratory failure,
brain seizures.
49Withdrawal symptoms
- Hallucinations
- Eating disorders
- Disorientation
- Vomiting
- Sleep disorders
50Barbiturates and other depressants
- When combined with other CNS depressants like
Demerol, heroin, morphine, and codeine it is
extremely dangerous. The combination of alcohol
and barbiturates can often be lethal. - If one has allergies and takes antihistamines
along with barbiturates this may cause
respiratory arrest.
51Barbiturates and stimulants
- Barbiturates are often used to counteract large
doses of stimulants such as cocaine or
amphetamines. - This mixture may cause increased heart rate and
coronary arrest.
52The Chemistry of Depression
- Neurological research has identified over 50
kinds of neurotransmitters. Scientists have found
that several neurotransmitters are directly
related to mental health problems. These specific
neurotransmitters are Dopamine, Serotonin,
Norepinephrine, and Gamma Aminobutyric Acid. A
shortage or excess of these neurotransmitters are
thought to be responsible for emotional disorders
like anxiety, depression, ADHD, social anxiety
and mood disorder. - There are three basic molecules, known chemically
as monoamines, which are thought to play a role
in mood regulation norepinephrine, serotonin and
dopamine. - website
53Neurotransmitterswebsite
- How They Work Once the brain's three
neurotransmitters, known as monoamines
(serotonin, norepinephrine, and dopamine), have
played their part in sending messages in the
brain, they get burned up by a protein in the
brain called monoamine oxidase, a liver and brain
enzyme. Antidepressants known as monoamine
oxidase inhibitors work by blocking this cleanup
activity. When the excess neurotransmitters don't
get destroyed, they start piling up in the brain.
And since depression is associated with low
levels of these monoamines, it's not surprising
that increasing the monoamines ease depressive
symptoms. Unfortunately, monoamine oxidase
doesn't just destroy those neurotransmitters
it's also responsible for mopping up another
amine called tyramine, a molecule that affects
blood pressure. So when monoamine oxidase gets
blocked, levels of tyramine begin to rise, too.
And that's when the trouble starts. While a
hike in neurotransmitters is beneficial, an
increase in tyramine is disastrous. Excess
tyramine can cause a sudden, sometimes fatal
increase in blood pressure so severe that it can
burst blood vessels in the brain. Every time
you eat chicken liver, aged cheese, broad-bean
pods, or pickled herring, tyramine floods into
your brain. Normally, MAO enzymes take care of
this potentially harmful tyramine excess. But if
you're taking an MAO inhibitor, the MAO enzyme
can't stop tyramine from building up. This is
exactly what happened when the drugs were
introduced in the 1960s. Because no one knew
about the tyramine connection, a wave of deaths
from brain hemorrhages swept the country. Other
patients taking MAO inhibitors experienced severe
headaches caused by the rise in blood pressure.
These early side effects were particularly
disturbing because nobody knew why they were
happening.
54Neurotransmitters
55SSRIs
- Serotonin Re-Uptake Inhibitor Impairing Body
Serotonin Metabolism SSRI's are "Selective
Serotonin Re-Uptake Inhibitors." Neuronal
re-uptake of neurotransmitters is metabolism.
What serotonin re-uptake inhibitor actually means
is that the SSRI-antidepressant interferes with
ones ability to metabolize serotonin, so that
will build up. In other words, an
SSRI-antidepressant impairs the ability of cells
to metabolize serotonin, not only in the brain,
but -since serotonin is widely distributed
throughout the body- in the body as well!
56Serotonin info.
- In the brain, messages are passed between two
neurons (nerve cells) via a synapse, a small gap
between the cells. The neuron that sends the
information releases neurotransmitters (with
serotonin among them) into that gap. The
neurotransmitters are then recognized by
receptors on the surface of the recipient cell,
which upon this stimulation, in turn, relays the
signal. About 10 of the neurotransmitters are
lost in this process, the other 90 are released
from the receptors and taken up again by
monoamine transporters in the sending cell (a
process called reuptake). - Depression has been linked to a lack of
stimulation of the recipient neuron at a synapse.
To stimulate the recipient cell, SSRIs inhibit
the reuptake of serotonin. As a result, the
serotonin stays in the synaptic gap longer than
it normally would, and has the chance to be
recognized again (and again) by the receptors of
the recipient cell, which can finally be
stimulated fully
57Serotonin Levels
- Serotonin Levels
- General Effects
- "This neurotransmitter regulates
- the onset of sleep,
- sensory perception,
- mood and depression,
- body temperature,
- Normal Serotonin Levels
- "Regulates sleep,
- reduces pain and appetite, and
- generally calms you down and improves
your mood.
58Serotonin Levels
- Low Serotonin Levels
- "Low levels of serotonin are associated with
- increased carbohydrate cravings
- depression
- heightened sensitivity to pain, and
- troubled sleep patterns
- Very low levels suicide/violent crimes/drug
abuse/hostility/impulsiveness/OCD/eating
disorders - Higher Serotonin Levels
- "When serotonin levels are increased,
- carbohydrate cravings subside,
- mood is elevated,
- pain tolerance improves, and
- sleep is more restful.
- Very High Levels schizophrenia/mood
disorders/psychosis/autism
59Depression and Serotonin cont
- Low serotonin levels are believed to be the cause
of many cases of mild to severe depression which
can lead to symptoms such as anxiety, apathy,
fear, feelings of worthlessness, insomnia and
fatigue. The most concrete evidence for the
connection between serotonin and depression is
the decreased concentrations of serotonin
metabolites in the cerebrospinal fluid and brain
tissues of depressed people.
60Dopamine, Depression and Drug Addiction
- A third substance that may play a role in mood is
dopamine. Dopamine is associated with the reward,
or reinforcement, that we get which causes us to
continue participating in an activity. It has
been implicated in such conditions as Parkinson's
Disease and schizophrenia. There is also some
evidence that, at least for a subset of patients,
dopamine plays a role in depression.6
Dopaminergic substances and stimulants have been
used as antidepressants when other measures have
failed.7 Some studies have investigated
dopaminergic agents as a rapid method of
relieving depression (in contrast to medications
which may take up to six weeks to exhibit their
full effect).8 - Although agents that work selectively on dopamine
have the benefit of fast action, they have also
exhibited some properties which have kept them
from being as widely used as other
antidepressants. Dopamine is a neurotransmitter
that is associated with addiction and it's
production is stimulated by drugs such as
cocaine, opiates and alcohol (which may explain
why depressed persons choose to self-medicate
with drugs and alcohol - Dopamine website
61Alkaloids
- -basic compound obtained from a plant
- -many have physiological effects
- -widespread in nature, structures vary
- (see examples below)
62Opium based drugs
63Opium
64Opium(Papaver somniferum)
- \ô-pë-æm\ n ME, fr. L. fr. Gk. Opion, fr. Dim.
Of opos sap an addictive narcotic drug that is
the dried juice of a poppy
65Opium Please!
- Opium is grown mainly in India and Turkey.
- The legitimate world demand for opium amounts to
about to about 680 metric tons a year, but many
times that amount is distributed illegally.
66Process.
- It is processed into the alkaloid morphine
which has long served as the chief painkiller in
medical practice, although synthetic substitutes
such as meperidine (trade name Demerol) are now
available. Heroin, a derivative of morphine, is
about three times more potent. Codeine is another
important opium alkaloid.
67Molecules of opiates have painkilling properties
similar to endorphins/enkephalins produced in the
body.
They occupy many of the same nerve-receptor sites
and bring on the same analgesic effect as the
bodys natural painkillers.
68OUCH!!!
- Narcotic analgesics,aka opioids, include opium
and the natural opium derivatives codeine and
morphine synthetic derivatives of morphine such
as heroin and synthetic drugs such as meperidine
and propoxyphene hydrochloride. Narcotics relieve
pain by acting on specific structures, called
receptors, located on the nerve cells of the
spinal cord or brain.
69Give me more!
- In the 1970s scientists isolated substances
called enkephalins, which are naturally occurring
opiates in the brain. They discovered what many
believe is the reason behind physical dependence
on opioidsthat is, the drugs may mimic the
action of enkephalins. If true, this hypothesis
suggests that physical dependence on opioids may
develop in people who have a deficiency of these
natural substances.
70Just Say NO!
Today opium is sold on the street as a powder or
dark brown solid and is smoked, eaten, or
injected. Heroin addicts in the U.S. number close
to half a million people. Although the synthetic
narcotic methadone has been used to offer addicts
some relief from opiates, it is itself addictive.
Complete recovery from opiate addiction requires
years of social and psychological rehabilitation
71Opium
- "One must not think life withthe mind, but with
opium"-André Malraux - "It banishes melancholy, begets confidence,
converts fear into boldness, makes the coward
eloquent, and dastards brave. Nobody, in
desperate circumstances, and smiling under a
disrelish for life, ever laid violent hands on
himself after taking a dose of opium, or ever
will."John Brown(1735 - 1788)
Julie Woods
72Opium Uses and Physiology
- Opium is prescribed to treat diarrhea or pain.
- Opiates slow respiration and heartbeat, suppress
the cough reflex, and relax the smooth muscles of
the gastrointestinal tract - Opiates act by binding to specific receptor
melocules for the endorphin/enkephalin class of
neurotransmitters in the brain. These are among
the neurotransmitters that control movement,
moods, and physiology.
73Chemistry of Opium
- Opium contains over 30 alkaloids. The most
abundant of which is Morphine, Codeine, and
Thebaine. The opium alkaloids are largely
combined with the dibasic acid, meconic acid. - Morphine
Meconicacid
74Effects of Opium
- Euphoria
- sense of emotional detachment
- absence of pain and stress
- altered mood and mental processes
- Sleepiness
- Vomiting
- loss of appetite
- reduced sex drive
- itchy skin
- increased urination
- Sweating
- inability to concentrate
- impaired vision
- death
75Side/Withdrawal effects
- The most detrimental side-effect of Opium is
addiction. People have to continue taking opium
or suffer terrible withdrawal effects like - Malnutrition
- respiratory complications
- low blood pressure
- mental and physical health problems
- severe constipation
- contracted pupils
- Moodiness
- menstrual irregularities
- lung, liver, kidney and brain damage
- collapsed veins from injecting the drug
- loss of weight
- reduction of sex hormone levels
- frequent infections
- pregnancy complications including still birth
- death
76Historical Background
- Opium began being used as a medical drug as early
as 100 A.D. - Opium Wars- Britain flooded China with opium,
forcing them into addiction. The Chinese
Government banned opium, but the trade continued
illegally. - This escalated into a trading war in 1839
- Conflict began a long history of Chinese
suspicion towards the West.
77Morphine
78The History of Morphine
- Morphine comes from opium which is derived from
poppy plants. Morphine was first isolated form
opium in 1805 by Friedrich Serturner. - It wasnt until almost 50 years later, when the
hypodermic needle was invented, that morphine was
widespread.
79History of Morphine Continued
- Morphine is now the most widely used analgesic
after almost 200 years of being discovered.
80Chemistry of Morphine
- Morphine is an alkaloid that is extracted for
opium. It is used as a pain killer and can be
taken in many forms such as injected, smoked,
sniffed or swallowed.
81Uses of Morphine
- Morphine is primarily used as a very strong pain
reliever. For both moderately sever to very sever
pain.It can be used for relief of certain types
of labored or difficult breathing and is
sometimes rarely used for sever cough.
82Uses Continued
- If a person has a chronic or debilitating illness
morphine may be given regularly but this is still
being debated by doctors.
83Uses Continued
- If morphine is abused or taken for a long time a
profound physical and psychological dependency
may occur. But even though it is addictive it is
rarely found as a street drug but is refered to
as M, morph or Miss Emma.
84Uses Continued
- Because of the risk of dependency for the drug,
doctors practice strict regulations on it.
Overall, Morphine is a very good pain reliever
but must be treated with respect.
85Is Morphine in Cheese?
- Morphine, of course, is an opiate and is highly
addictive. So how did it get into milk? At first,
the researchers theorized that it must have come
from the cows' diets. After all, morphine used in
hospitals comes from poppies and is also produced
naturally by a few other plants that the cows
might have been eating. But it turns out that
cows actually produce it within their bodies,
just as poppies do. Traces of morphine, along
with codeine and other opiates, are apparently
produced in cows' livers and can end up in their
milk. - But that was only the beginning, as other
researchers soon found. Cow's milk-or the milk of
any other species, for that matter-contains a
protein, called casein, that breaks apart during
digestion to release a whole host of opiates,
called casomorphins. A cup of cow's milk contains
about six grams of casein. Skim milk contains a
bit more, and casein is concentrated in the
production of cheese. - If you examined a casein molecule under a
powerful microscope, it would look like a long
chain of beads (the "beads" are amino
acids-simple building blocks that combine to make
up all the proteins in your body). When you drink
a glass of milk or eat a slice of cheese, stomach
acid and intestinal bacteria snip the casein
molecular chains into casomorphins of various
lengths. One of them, a short string made up of
just five amino acids, has about one-tenth the
pain-killing potency of morphine. - What are these opiates doing there, hidden in
milk proteins? It appears that the opiates from
mother's milk produce a calming effect on the
infant and, in fact, may be responsible for a
good measure of the mother-infant bond. No, it's
not all lullabies and cooing. Psychological bonds
always have a physical underpinning. Like it or
not, mother's milk has a drug-like effect on the
baby's brain that ensures that the baby will bond
with Mom and continue to nurse and get the
nutrients all babies need. Like heroin or
codeine, casomorphins slow intestinal movements
and have a decided antidiarrheal effect. The
opiate effect may be why adults often find that
cheese can be constipating, just as opiate
painkillers are.
86Cheese and Morphine continued
- It is an open question to what extent dairy
opiates enter the adult circulation. Until the
1990s, researchers thought that these protein
fragments were too large to pass through the
intestinal wall into the blood, except in
infants, whose immature digestive tracts are not
very selective about what passes through. They
theorized that milk opiates mainly acted within
the digestive tract and that they signaled
comfort or relief to the brain indirectly,
through the hormones traveling from the
intestinal tract to the brain. - But French researchers fed skim milk and yogurt
to volunteers and found that, sure enough, at
least some casein fragments do pass into the
bloodstream. They reach their peak about 40
minutes after eating. - Cheese contains far more casein than other dairy
products do. As milk is turned into cheese, most
of its water, whey proteins, and lactose sugar
are removed, leaving behind concentrated casein
and fat. - Cheese holds other drug-like compounds as well.
It contains an amphetamine-like chemical called
phenylethylamine, or PEA, which is also found in
chocolate and sausage. And there are many
hormones and other compounds in cheese and other
dairy products whose functions are not yet
understood. In naloxone tests, the
opiate-blocking drug eliminates some of cheese's
appeal, just as it does for chocolate.

89Morphine facts
- Morphine is a naturally occurring substance in
the opium poppy, Papayer somniferum. - It is a narcotic analgesic, used primarily for
pain - After Heron, it has the highest dependency for
these type of drugs - Taken by Injection, smoking, sniffing or
swallowing
90More Morphine fact
- Produces euphoria and a general state of
relaxation - Also used to relieve breathing problems, and
severe coughs
91With the invention of the hypodermic needle
during the American Civil War, the injection of
morphine became indispensible in treating
patierts who had to undergo some sort of surgery.
Physicians of that time hoped that injecting
morphine directly into the blood stream would
avoid the addictive effects of smoking or eating
opium, but instead it proved more addictive.

- Suppresses narcotic withdrawal for 24-36 hours
- Patients are able to perceive pain
and have emotional reactions - Relieves the cravings associated
with heroin addiction
liquid methadone
108Prescription Pain Relief
- Oxycodone (oxycontin) (oxycodone
hydrochloride)-semisynthetic opiate derived from
opioid alkaloid similar to codeine (called
thebaine) - Vicodin-acetaminophen and hydrocodone
- Percocet-acetaminophen and oxycodone
- All are narcotics, addictive, moderate to high
pain relief, CNS depressants,
109Pain relief medication
110Oxycodone
- is a central nervous system depressant
- stimulate opioid receptors in central nervous
system that cause responses from respiratory
depression to euphoria - tolerance and resistance can develop
- patients seek to gain the euphoric effects,
mitigate pain, and later avoid the withdrawal
symptoms of heroin and oxycodone - comes from the alkaloid codeine found in opium.
111Side Effects / Overdose
- Side Effects dryness of the mouth, confusion,
sedation, light-headedness, respiratory
depression, nausea, vomiting, headache, sweating - Overdose slow breathing, seizures, dizziness,
weakness, loss of consciousness, coma, confusion,
cold or clammy skin, small pupils
112 Legal Uses
- oxycodone is combined with
- - aspirin to make the drug Percodan
- - acetaminophen to make Percocet(Vicodan)
- - OxyContin is oxycodone along with
time-release tablets. - All are prescription pain-killers used for high
pain relief.
113What is the difference between percocet and
percodan?
- Answer BOTH CONTAIN THE NARCOTIC OXYCODONE,
BUT ONE HAS ASPIRIN, AND THE OTHER ACETAMINOPHEN
(TYLENOL)Percodan is the brand name for the
combination of acetylsalicylic acid (aspirin) and
oxycodone. Percodan is prescribed for moderate
to moderately severe pain. Oxycodone binds to the
pain receptors in the brain so that the sensation
of pain is reduced. Acetylsalicylic acid halts
the production of prostaglandins which otherwise
cause pain. It is available in tablet, capsule,
and liquid form and is taken every 6 hours by
mouth. Since oxycodone can be habit forming, care
must be taken to follow the doctor's instructions
when taking PercodanÂ. Do not take a larger
dose, or take it more frequently, or take it for
longer than the doctor has prescribed. nothing
Percocet has a narcotic (oxycodone) combined with
acetaminophen (Tylenol) Percodan combines the
same narcotic with aspirin. Percocet contains
Oxycodone and Acetominophen (Tylenol). Percodan
contains Oxycodone and Aspirin
114Illegal Uses
- Street Names OC, OX, Oxy, Oxycotton, Blue,
Hillybilly Heroin, Kicker - The time-release tablets of OxyContin, are
crushed and then the powder is snorted. The
powder is also water soluble and is dissolved and
then injected. - The full 12-hour dose of oxycodone is taken in
one hit. - Unless prescription, it is illegal to have the
substances. - Oxycodone related drugs have high dependency and
have been abused for close to 30 years. A sharp
raise in abuse rates occurred when OxyContin was
introduced in 1996.
115Short Term Effects
- Analgesia, sedation, euphoria, feelings of
relaxation, respiratory depression, cough
suppression - Behavioral effects last 5 hrs. Controlled time
release tablets, OxyContin, lasts 8-12 hrs. - When abused, the high (a sedate, euphoric
feeling) lasts up to 5 hours
116Long Term Effects
- Abuse may lead to dependence and tolerance
- Chronic use leads to tolerance
- The body can adapt to the presence of the drug
and withdrawal symptoms will occurred if use is
stopped - If taken exactly as prescribed, opioids can be
used to manage pain effectively.
117Cocaine
- Alkaloid substance and CNS stimulant
118Cocaine Production
pure cocoa leaves are harvested and lime water
and kerosene are added this is left to sit for
1- 4 days
this paste is taken and sulfuric acid is added
mixture is then filtered and dried
ammonium hydroxide is then added, and the
substance is dried again, creating what is called
cocaine base
this base is dissolved into a pool of acetone and
pool acid is added over time, a white substance
will form at the bottom which is filtered and
dried for shipment
119Chemistry and Production
Extracted from the leaves of the cocoa plant
(erthroxylon coca) which is located primarily in
Southern America.
The stimulant is formed by adding specific
amounts of various chemicals to enhance potency
and form the well known white powder substance
which is sold illegally (in solid form cocaine is
called crack).
120Hey! A Cocaine Timeline!
The Incas in South America chewed coca leaves to
increase energy, strength, and stamina.
Early Civ.
1800s
German chemist Albert Niemann identifies the
South American Erythroxylon coca bush and uses
it in an elixir to treat his patients. It is
also used as an anesthetic for surgery and taken
by many for energizing effects.
Psychiatric pioneer Sigmund Freud cites cocaine
in various essays as a potential cure for a
myriad of ailments.
Continued on Next Slide...
121Documents arise concerning cocaine dependency,
and associating the stimulant with various
psychological and physical ailments.
1900s
In 1902, 92 of all the cocaine used in America
could be found in tonics at ones local pharmacy,
among these was the energizing drink Coca - Cola,
which originally contained the stimulant.
Cocaine use is restricted in 1908 from medicines
entirely.
122Effects on the Body
-Cocaine is a central Nervous System stimulant
which is ingested through the nose, smoked in its
solid form, and seldom injected -Cocaine
provides the user with a rush,or an increase in
energy which causes chemicals in the brain to
synthetically provide pleasure to the user
-After ingested, the effects of cocaine are
short - term and usually in 15 - 20 minutes,
disappearing after 1 hour -Once cocaine is
taken, one can expect to experience an increased
heart rate and breathing, dilated pupils,
constricted blood vessels, increased blood
pressure and the shakes -Over time, a frequent
cocaine user may experience weight loss,
ulceration of the nasal membrane, cardiac arrest
(overdose), and seizures
123The physiological components of a human combined
with the potent chemicals of cocaine produce the
popular rush that some 3.7 million Americans
today have felt the reasons for this energizing
high are as follows
-cocaine hydrochloride (white crystalline powder)
alterneurotransmitters (substances in the brain
which respondto nerve impulses) -cocaine
specifically enhances the neurotransmitter
dopamine at its receptor sites (located in the
midbrain), which is thought to be involved in
emotional responses -the autonomic nervous
system (where nerve impulses from the central
nervous system transmit self - governedimpulses
to muscles and glands) is elevated and this
causes the rush associated with cocaine
124Physiological Effects
-While using cocaine, one may experience anxiety,
paranoia, depression, loss of ambition,
confusion, and overconfidence
-Due to the fact that cocaine is an addictive
substance, a user will inevitably have withdrawal
symptoms when he decides to stop using these
symptoms include irritability, loss of
motivation, nausea, and unclear thinking
-Studies have shown that a regular cocaine user
can (after a period of discomfort and withdrawal)
successfully quit using the drug and redeem his
health over time. For some, however, the highly
addictive nature of the drug can overcome any
desire to quit
-It is very hard for some to quit using cocaine
because of the kindling effect, where a user
will become more sensitive to the drug with
prolonged use, thereby intensifying ones high
with each use
125 Due to the fact that cocaine is not only
available in metropolitan cities but suburbs as
well, its use is still widespread and highly
illegal
-3.7 million American were reported to use
cocaine in 1999 this is drastically lower than
1982s report of 10.2 million
-4.7 of eighth graders in 1999 report using
cocaine at least once
-the average age of a first time cocaine user is
20.6 years
-over 75 of the worlds cocaine is produced in
high altitude rainforests of Columbia, and
smuggled over borders
-cocaine is responsible for over 150,000
emergency room incidents and 3,500 deaths per
year on average
