2Basic Psychopharmacologyfor Children and
Adolescents
- Prescribing psychoactive medication for
children is controversial. However, at times it
is necessary to assist children in controlling
problems with mood, behavior, anxiety, aggression
and other difficulties. As a clinician I have to
be convinced that to not medicate would be more
harmful than to proceed with medication
treatment.
3 - Today we will discuss common reasons for
prescribing medications and the specific
medications prescribed for those problems.
4Disorders of Concentration, Attention and
Hyperactivity
- One of the most common reasons psychoactive
medication is prescribed in children is related
to problems associated with disruptive behavior.
In particular problems with concentration, and
hyperactivity. -
5 - Choices of medications for these problems
include - Stimulants
- Strattera
- Alpha adrenergic agonist
- Some antidepressants
6 - There are two basic types of stimulants
- Methylphenidates
- Amphetamines
7Methylphenidate (Ritalin)
- Methylphenidate (Ritalin) is one of the
oldest of the stimulant medications used in the
treatment of attention and concentration
problems. - In general, methylphenidate is well
tolerated and works well to increase
concentration and attention and to decrease
hyperactivity. It works about 80 of the time to
reduce up to 80 of the symptoms a person is
experiencing.
8Methylphenidate (Ritalin)
- Side effects include decreased appetite,
decreased or disturbed sleep, sometimes headaches
and gastrointestinal pains. At times motor or
vocal tics emerge. There can also be problems
with mood instability and with irritability. In
overdose you can see psychotic symptoms or
symptoms of delirium.
9Methylphenidate (Ritalin)
- Problems can also arise with methylphenidate
because of the short half-life of the standard
formulation. Theoretically dosing can occur
every four hours but clinical experience leads to
dosing as frequently as very 150 minutes. There
are other forms of the medication that have
longer duration of action including but not
limited to Ritalin LA, Metadate CD, Concerta,
Methylin and now Daytrana (a patch).
10Dextromethylphenidate
- Focalin and FocalinXR both prescribed in similar
fashion to other stimulants. Side effects are
similar. The difference is perhaps in
specificity.
11Mixed Amphetamine SaltsAdderall and AdderallXR.
- Mixed amphetamine salts have also been
available in the treatment of attention and
concentration for many years. They are currently
available in generic and under the trade name of
Adderall and AdderallXR. Â - These medications are very effective in
decreasing the symptoms of poor attention, poor
concentration, and hyperactivity. Their
effectiveness is similar to methylphenidate and
they are very widely used.
12Mixed Amphetamine SaltsAdderall and AdderallXR.
- Side effects are also similar to those listed
above with methylphenidate but in clinical
experience they are slightly more likely to
create some mood lability and irritability than
the other stimulant medications. - A new amphetamine is Vyvanse a
- pro-drug.
13 Dextroamphetamine
- Dextroamphetamine has also been used for
years in the treatment of problems with
attention, concentration and the regulation of
activity level. Sold under the trade name of
Dexedrine or Dexedrine Spanules. - Dextroamphetamine is effective in
reduction of symptoms at a level consistent with
the treatments listed above. - Side effects are similar to those listed
above.
14 Other Medication Options for Attention,
Concentration and Over activity
- The mainstay of therapy for problems with
concentration and attention is stimulant
medication. While stimulants are very effective
medications there have been problems with their
use because of the relatively short half life of
each of these preparations. Even at their
longest the medications rarely last greater than
8 hours and often times patients can experience a
sort of rebound hyperactivity once the medication
has worn off.
15Atomoxitine (Strattera)
- A noradrenergic reuptake inhibiter that
appears to have relatively good effectiveness in
decreasing levels of hyperactivity and in helping
with increasing attention, concentration, and
organization. It has been approved for use in
children as young as 6 years old weighing above
forty pounds. It generally has lasting effects
throughout the day and into the evening. Problems
have included changes in appetite and also nausea
along with some sleep problems
16Centrally acting alpha adrenergic agonist
- Clonidine and guanfacine have also been very
useful in decreasing levels of hyperactivity and
in increasing attention and concentration. They
are not necessarily as effective as stimulant
medications but they are effective in a group of
very aroused patients. Side effects are limited
to problems with drowsiness and with hypotension.
17Venflaxamine (Effexor)
- Venflaxamine (Effexor) a mixed serotonin and
noradrenergic reuptake inhibiter that has been
used in the treatment of difficulties related to
concentration, attention and regulation of
activity level with some limited success.
Recently, Venflaxamine has come under increasing
scrutiny because of issues related to possible
increased suicidal ideation and suicidal
behaviors in children and adolescents taking
serotonin reuptake inhibiters. Other problems
have included increased irritability and possible
increases in blood pressure.
18Buproprion (Wellbutrin)
- Buproprion (Wellbutrin) is an anti-depressant
medication that is sometimes used in the
treatment of problems with attention and
concentration. Buproprion can be reasonably
effective in the reduction of symptoms but must
be used with caution in children or adolescents
with history of seizures, head injury or bulimia.
(This medication has also been included in the
list of antidepressants where care as to be given
secondary to fears of increased suicidal
thoughts or behaviors.)
19Tri-cyclic Antidepressants
Tri-cyclic antidepressants have also been used
successfully in the treatment of problems with
attention, concentration and regulation of
activity levels. The tri-cyclics used in children
most often include imipramine and nortrityline.
They generally have good effectiveness over
twenty four hours but they can have troublesome
side effects that include a widening of the QRS
as measured on EKG. Also they can lead to
drowsiness, weight gain, dry mouth and
constipation. It is also generally important to
check serum levels of these medications while a
child is being treated.
20Anxiety
- Anxiety disorders as a group are very common
in children in general and are often misdiagnosed
or overlooked if a thorough history is not
obtained. Misdiagnosis can be of particular
concern where medications are concerned. The
wrong medication can serve to exacerbate symptoms
associated with anxiety and lead to increased
morbidity for the child.
21Serotonin Reuptake Inhibitors
- Since their introduction in the last several
years the serotonin reuptake inhibitors have been
the treatment of first choice in the treatment of
anxiety. Fluoxetine (Prozac), sertraline
(Zoloft), paroxitine (Paxil), citalopram
(Celexa), escitalopram (Leapro), and fluvoxamine
(Luvox). These medications taken as a whole have
been very effective in reducing anxiety and also
in decreasing anxiety related symptoms associated
with perseveration and preoccupation. In general
they should be used starting at low doses for
most patients but especially with those diagnosed
with pervasive developmental disorders. The
medications should be gradually titrated to
desired effect. Care should be given to look for
the emergence of any agitation or irritability
and these medications have been known to induce
mania in predisposed patients. Also added care
should be given to observe for any signs or
symptoms associated with increased suicidal
ideation or suicidal behaviors. Â Â Â Â Â Â
22 Benzodiazepines
- Benzodiazepines as a class are excellent anti
anxiety medications. They can be very effective
in the treatment of anxiety related problems in
the developmentally disabled. These
medications include but are not necessarily
limited to diazepam, alprazolam, lorazepam,
chlordiazepoxide, clonazepam, chlorazepate,
oxazepam, flurazepam, and temazepam. Problems
arise in these medications most often relate to
somulence, difficulty with short term memory,
development of tolerance requiring increasingly
higher doses, and also with the half life and
active metabolites of some of the medications in
this class leading to unwanted prolonged effects.
23Buspirone (Buspar)
- Buspirone (Buspar) is an anxiolytic that can
have some success in the treatment of anxiety.
While not always successful in relieving anxiety
it is a medication with very few side effects and
is well tolerated. Generally, problems arise
from needing to dose up to three times a day and
it has a relatively slower onset of action
sometimes taking up to three weeks to achieve
clinically significant effect.
24Venflaxamine (Effexor)
- Venflaxamine (Effexor) is a combination
serotonin reuptake inhibitor and noradrenergic
reuptake inhibitor that has been clinically
effective in decreasing anxiety symptoms. It has
generally been well tolerated but there have been
problems with sleep disturbance and even
drowsiness on the medication. There have also
been problems with elevations in blood pressure.
25Tri-cyclic antidepressants
- Tri-cyclic antidepressants such as imipramine
and nortriptyline can also be effective
anxiolytics. However, they may take up to 4
weeks to work effectively once an adequate serum
level has been obtained. As when using in these
medications in the treatment of other symptoms,
care must be given to monitor the EKG to insure a
QTc that is within acceptable clinical
parameters. Also as stated above problems with
high anticholinergic side effects can lead to
problems like dry mouth, constipation, and
drowsiness.
26Antihistamines
- There are times when anti-histamines such as
hydroxyzine or diphenhydramine are prescribed to
relief anxiety. While these medications may be
effective in the short run sedating a patient and
calming the crisis they are generally not good
medications for long-term use in the treatment of
ongoing anxiety symptoms.
27Mood Problems
- Depression and mood disorders certainly
exist in children and often times psychotropic
medications can be of assistance. More
controversial currently is the diagnosis of
Bipolar Disorder in a pediatric population.
Great care is needed to ensure an accurate
diagnosis so that appropriate treatment is given,
especially when it comes to medications.
28Depression
- The generally accepted first line of treatment
for depression is the choice of a selective
serotonin uptake inhibitor. Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â
                                                 Â
                            -     Â
29Serotonin Reuptake InhibitorsÂ
- These medications that were listed above
include fluoxetine (Prozac), sertraline (Zoloft),
citralopram (Celexa), escitralopram (Lexapro),
fluvoxamine (Luvox), and paroxetine (Paxil). All
of these medications have generally the same
level of effectiveness in the treatment of
depression and choices are often made based upon
side effect profiles or the past response to a
particular medication by the patient or a close
relative of the patient. These are generally
considered safe and effective medications
although their use in children has not been
extensively studied.
30Serotonin Reuptake InhibitorsÂ
- Side effects in this class of medication are
generally related to gastrointestinal problems,
sometimes problems with sleep, and all generally
tend to create problems with sexual function (in
adults) that is usually related to decreased
orgasm but there can also be decreased desire.
31Serotonin Reuptake Inhibitors
- These medications can also cause problems
with increased irritability and at times they can
induce mania in individuals with that
predisposition. Care should be given especially
when giving to individuals with a strong family
history of Bipolar Disorder. Individuals with
Pervasive - Developmental Disorders as well can be very
susceptible to side effects of irritability and
mood instability. These medications should be
used at low doses and with appropriate caution.
Care also should be given as mentioned above to
issues associated with potential suicidal
ideation and behavior.
32Buproprion (Wellbutrin)
- Buproprion (Wellbutrin) is effective in the
treatment of depression and in general has been
well tolerated. It has advantages over the other
anti depressants used in adults in that it is
generally accepted that it has fewer sexual side
effects. This medication has also appeared to be
less likely to create difficulties with inducing
mania in individuals that may be vulnerable.
33Buproprion (Wellbutrin)
- Buproprion must be used in caution with
individuals that have a history of head injury or
those with seizure disorder or history of
bulimia. These individuals may be at higher risk
for seizure on this medication. Newer
formulations of buproprion have lengthened the
half-life of the medication and this has led to
less risk of seizure in individuals. It still
should not be given to individuals with the risk
factors noted above.
34Venflaxamine (Effexor)
- Venflaxamine (Effexor) is a combination
selective serotonin reuptake inhibitor and
noradrenergic reuptake inhibitor. It has been
effective in the treatment of depression and is
generally well tolerated. There have been
problems as noted above with increase blood
pressure and there have also been complaints
related to sexual function.
35Tri-cyclic antidepressants
- Tri-cyclic antidepressants have long been and
in some circles continue to be the gold standard
for the treatment of depression. These
medications while they do have quite a few side
effects in general have been well tolerated and
are effective in relieving symptoms. These
medications include imipramine, nortriptyline,
amitriptyline, and clomipramine. They all work
in varying degrees on the same neurotransmitter
systems that have been mentioned above but each
to a different degree and with a different level
of specificity for a particular neurotransmitter.
This difference in neurotransmitter effect and
the side effect profiles of each allows a
clinician to attempt a good match for treatment
with these medications.
36Tri-cyclic antidepressants
- All of these medications generally have high
anticholinergic profiles. Side effects are
usually problems with sleepiness, weight gain,
dry mouth, constipation, etc. - These medications also generally cause an
increase in the time interval associated with the
QRS complex as measured with an EKG. This can
lead to dangerous arrhythmias during the course
of treatment.
37Tri-cyclic antidepressants
- Because of each of the side effect
difficulties listed above these medications can
be fatal in overdose. This is generally not seen
with the other medications that have been listed
above for the treatment of depression. Given
that by its very nature depression can have as a
core symptom of morbid preoccupation and
suicidality these medications must be given
cautiously and monitored closely.
38Other medications
- Other medications have been used effectively
as adjuncts to those listed above when treating
depression. So called mood stabilizers such as
lithium or valproic acid or other anticonvulsants
have been used to try and decrease symptoms in a
marginally responsive or non-responsive patient.
Other medications that have been used with some
effectiveness include stimulants and even thyroid
hormone supplementation. Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â
                        - Adolescent girls, who have achieved menarche,
and women sometimes respond well to adjuncts of
oral or depo contraceptive medications for
depressive symptoms.
39Electroconvulsive Therapy
- While medications have been very effective in
relieving the symptoms of depression it should
also be noted that electroconvulsive therapy is
also a very effective somatic treatment. There
are side effects associated with short-term
memory problems and the risk associated with
anesthesia but overall the patients respond well
and quickly to this somatic treatment. Many
centers have even moved to offering this
treatment in a day hospital setting with no over
night stays. Â
40Bipolar Disorder
- Bipolar Disorder is seen in children and
while it is a discussion not within the scope of
this discussion it can often present in an
atypical fashion. Determining core symptoms of
grandiosity, racing thoughts or flight of ideas
with increased goal oriented pursuits may be
difficult to discern and features related to
irritability and hypersexuality may be difficult
to tease from behaviors of other disorders or
problems. - Medications used to treat bipolar disorder
are generally called mood stabilizers but there
are mood stabilizers in several different
classes of medications.
41Lithium
- Lithium has long been the treatment standard
in the psychopharmacologic treatment of bipolar
disorder. It is an exceptionally effective mood
stabilizer and is generally well tolerated. It
does however have several side effects and has a
very narrow therapeutic window making it
potentially dangerous in overdose.Â
42Lithium
- Side effects include weight gain, diarrhea,
acne and less commonly problems with renal
function, possible hypothyroidism, and cardiac
rhythm problems.
43Lithium
- Blood levels need to be monitored carefully
and care has to be taken in patients that are on
medications or participate in activities that
would potentially increase the drugs serum
level.
44Divalproex (Depakote)
- Divalproex (Depakote) is also a very effective
mood stabilizing medication. It is generally
used as an anticonvulsant but it does currently
have approval from the FDA for use as a treatment
of acute mania. Â Â Â
45Divalproex (Depakote)
- Most patients tolerate divalproex (Depakote)
with few problems but there can be side effects.
It can lead to some gastrointestinal problems and
there can be increased appetite with weight gain.
Additionally, in women there has been a
correlation between divalproex (Depakote) use
and polycysitic ovaries. There have also been
problems with liver function, bone marrow changes
usually with a decrease in megakaryocytes and
subsequently platelets. In very rare cases
critical pancreatitis has been a problem. Blood
levels need to be monitored while the patient is
on divalproex (Depakote) in addition to
laboratory investigation of other systems that
might be affected.
46Other anticonvulsants
- Other anticonvulsants used to treat bipolar
disorder include but are not necessarily limited
to Neurontin, Lamictil, Tegretol, Trileptal, and
Topomax. These medications have been generally
helpful in treating some of the symptoms of
Bipolar Disorder. They have been generally well
tolerated, some more than others. They have
varying side effects and require different levels
of monitoring but all are currently part of the
armentareum used for treatment.
47Atypical Anti-Psychotic Medications
- Some of the new so-called atypical anti
psychotic medications are also being used in the
treatment of Bipolar Disorder especially to treat
acute manic phase. These include Zyprexa,
Geodon, Abilify, Risperdal, and Seroquel. These
medications too have been well tolerated by
patients but there are some concerning side
effects. While they do not have the risk of
tardive dyskensia associated with them that the
so-called typical anti psychotics possess there
is still a risk of this potentially irreversible
movement disorder. Also each carries risk of
acute extra pyramidal side effects including
acute dystonias, parkinsonism, and akathesia. All
have generally been associated with increased
appetite and weight gain and possible increase in
baseline glucose levels and lipid levels.
48Obsessive compulsive Disorder (OCD)
- Obsessive compulsive disorder usually
responds well to an appropriate medication
regimen. In addition to medication treatment
however cognitive and behavioral therapies are
important. Also symptoms of preoccupations and
perseveration are not necessarily OCD. Â - Psychopharmacologic treatment for OCD
revolves around the use of medications that
affect the serotonergic functions in the brain.
49 Obsessive compulsive Disorder (OCD)
- Any of the selective serotonergic reuptake
inhibitors can be very useful in the treatment of
OCD. As noted above these medications are well
tolerated and possess few side effects. Dosages
used to treat OCD are sometimes greater than
those used for the treatment of depression and
other anxiety disorders.
50Selective Serotonergic Reuptake Inhibitors
- These medications include the ones listed
above, fluoxetine (Prozac), paroxetine (Paxil),
sertraline (Zoloft), fluvoxamine (Luvox),
citalopram (Celexa), and escitalopram (Lexapro).
As noted above, care should be taken in
prescribing these medications related to recent
concerns about increased suicidal ideations
and/or suicidal behavior in children and
adolescents taking these medications. Â
51Clomipramine (Anafranil)
- Clomipramine (Anafranil) is a Tricyclic
antidepressant medication that has a primary
serotonergic action in the brain that has been
used for many years in the treatment of
Obsessive/Compulsive Disorder symptoms.
52 Clomipramine (Anafranil)
- Side effects with clomipramine (Anafranil)
include the usual side effects associated with
Tricyclic antidepressants. These are
anticholinergic side effects that include
increased appetite and weight gain, dry mouth,
and constipation. There are also the same
concerns associated with a widening in the QRS
complex as seen on an EKG. Such a widening in
the QRS complex as noted above can lead to
problematic arrhythmias. This medication is also
extremely toxic in overdose and can lead to death
because of the anticholinergic and cardiac side
effects associated with it.
53Clomipramine (Anafranil)
- Routinely, Clomipramine (Anafranil) serum
levels should be evaluated periodically.
Baseline EKG with routine follow up EKG should be
part of the post-prescription care given with
this medication
54Other medications
- Other medications are used to treat symptoms
associated with OCD. These medications include
other medications that help relieve anxiety.
These medications are medications in the
Benzodiazepine class and medications, in addition
to Clomipramine, that are in the tricyclic
antidepressant class. There are at times severe
OCD symptoms that seem to be helped by the
addition of antipsychotic medications, in
particular the newer atypical antipsychotic
medications that we have discussed above.
55Tourettes Disorder
- Tourettes Disorder is a collection of
symptoms associated with chronic vocal and motor
tics. Sometimes these tics can be very complex.
In addition to the chronic vocal and motor tics,
comorbid issues associated with emotional
lability and attention/concentration problems can
also be present. OCD is also likely to be
comorbid in individuals and in families of
individuals with Tourettes. Both Tourettes
Disorder and OCD can be the result of a
post-strep infection autoimmune syndrome.
56Tourettes Disorder
- Medications that have been used to treat
Tourettes Disorder include medications that
inhibit tic production and also those that
decrease anxiety. Of the medications that inhibit
tic symptoms whether vocal or motor, the most
effective group of medications is the
antipsychotic group. These seem to be helpful
because they block dopamine activity in the
subcortical structures of the brain that are
associated with movement. They are generally
quite effective in reducing tics, both vocal and
motor but do have substantial side effects, as
have been noted above.
57Risperdal
- A frequently used antipsychotic medication in
the treatment of Tourettes is Risperdal. Just
as in the treatment of other disorders with
antipsychotic medications, care has to be given
to monitor for both short-term acute side effects
that include extrapyramidal symptoms of
parkinsonism, akathisia, and acute dystonias as
well as longer-term side effects such as tardive
dyskinesia. Additionally, with the chronic use
of Risperdal as well as most of the older
so-called typical antipsychotics, prolactin
levels are increased and this can lead to
difficulties associated with possible
gynecomastia in males, particularly adolescents,
and possible lactation and decreased menstruation
in females. These atypical antipsychotics, as
noted above, are also possibly linked to
increased glucose levels in individuals taking
the medication and possible increased lipid
levels.
58Other Atypical Antipsychotics
- Other atypical antipsychotics that have been
used in the treatment of Tourettes Disorder
include Geodon, Seroquel, and Zyprexa. The newer
atypical antipsychotic Abilify, would probably
also be useful in decreasing tics in these
patients.Â
59Older So-Called Typical Antipsychotics or
Neuroleptics
- Older so-called typical antipsychotics such
as Pimozide and Haloperidol have also been shown
to be very effective in the treatment of
Tourettes Disorder. These medications decrease
disruption secondary to tics, both vocal and
motor. Both Haloperidol and Pimozide have
substantial side effects. These side effects
occur at a somewhat higher rate than the typical
antipsychotic group. They have been associated
with permanent, long-term side effects such as
tardive dyskinesia and at a much higher rate than
the atypical antipsychotics. Older antipsychotics
are also much more likely to have problems
associated with acute extrapyramidal side
effects. At times, adjunctive anticholinergic
medications are needed to decrease some of the
worrisome acute side effects of movement
associated with the older antipsychotics. Such
medicines as Cogentin, Vistoril, Artane, and
Benadryl have been used.
60Other Medications To Treat Tourettes Disorder
- Other medications have also been used with
relative success in decreasing tics in patients
with Tourettes Disorder. They also may have
some adjunctive effect in decreasing some of the
anxiety associated with Tourettes Disorder and
in helping with some of the comorbid
symptomatology associated with decreased
attention and concentration. The medications
most often used in this particular category are
the alpha adrenergic agonists that are centrally
acting. These include Quanfacine and Clonidine.
Both of these are essentially antihypertensives
and acting centrally seem to have some effect on
the decrease in tic production. Also by
decreasing the overall arousal level, they seem
to have a mild anxiolytic effect and seem to
increase concentration and attention. Side
effects associated with these medications include
sleepiness and/or feelings of being tired, both
associated with a somnolent effect of the
medications and their ability to decrease blood
pressure. Care has to be given to monitor blood
pressure to ensure that blood pressure does not
drop too precipitously. Usually, patients need
to be slowly titrated onto these medications and
then subsequently slowly titrated off.
61Other Medications To Treat Tourettes Disorder
- These include the anxiolytics that have been
noted above, including but not limited to,
Benzodiazepines, selective serotonin reuptake
inhibitors, Tricyclic antidepressants, and other
more atypical anxiolytics, including BuSpar.
62Psychotic Disorders
- Psychotic disorders do occur in children and
adolescents but they are not seen as often in
this population as in adults.
63Anti-psychotic medications
- Anti-psychotic medications, both the
newer atypical antipsychotic medications and the
older typical antipsychotic medications are the
mainstays for treatment of psychosis in any
individual. The medications that are used in the
treatment of psychotic disorders are those that
have been mentioned above, including but not
limited to, Risperdal, Zyprexa, Geodone,
Seroquel, Abilify, and the older more typical
antipsychotic medications that include Haldol,
Thorazine, Prolixin, Mellaril, Loxitane, and many
others. All of these medications, as has been
noted above, have substantial side effects
associated with them, not the least of which is
the possibility of permanent movement difficulty
associated with syndromes of tardive dyskinesia.
64Benzodiazepines
- In addition to these antipsychotic
medications in the treatment of psychosis.
Benzodiazepines can also sometimes be helpful in
treating agitation and irritability that exists
alongside the psychotic symptomatology. The use
of Benzodiazepines such as Ativan, Klonopin,
Valium, etc., can be very helpful in decreasing
the morbidity associated with psychotic symptoms.
65Conclusion
- Psychotropic medications can be helpful
adjuncts to mental health treatment in children
and adolescents but care needs to be given to
ensure appropriate diagnosis and follow up by a
professional trained to evaluate and use these
medications. - Judicious use in a collaborative atmosphere is
essential to success and safety.
