Questions.
Definition


Antidepressants:
are a class of drugs that reduce symptoms of
depressive disorders by correcting chemical
imbalances of neurotransmitters in the brain.
Chemical imbalances may be responsible for
changes in mood and behavior.
Definition
Neurotransmitters are vital, as they are the communication
link between nerve cells in the brain. Neurotransmitters
reside within vesicles found in nerve cells, which are
released by one nerve and taken up by other nerves.
Neurotransmitters not taken up by other nerves are taken
up by the same nerves that released them. This process
is called "reuptake." The prevalent neurotransmitters in
the brain specific to depression are serotonin, dopamine
and norepinephrine (also called noradrenaline).
Definition

n general, antidepressants work by inhibiting the
reuptake of specific neurotransmitters, hence
increasing their levels around the nerves within the
brain, such as selective serotonin reuptake inhibitors
(SSRIs), antidepressants that will affect serotonin
levels in the brain.
conditions are antidepressants
used
Antidepressants are used to treat several
conditions. They include, but are not limited to:
depression, generalized anxiety disorder,
agitation, obsessive compulsive
disorders (OCD), manic-depressive disorders,
childhood enuresis (bedwetting), major
depressive disorder, diabetic peripheral
neuropathic pain, neuropathic pain, social
anxiety disorder, posttraumatic stress
disorder (PTSD) etc.
conditions are antidepressants
used

Some off- label uses of antidepressants
include, but are not limited
to:fibromyalgia, chronic urticaria (hives), hot
flashes, hyperhidrosis (druginduced), pruritus (itching), premenstrual
symptoms, bulimia nervosa,Tourette
syndrome, binge eating disorder, etc.
Are there differences among
antidepressants?
Antidepressants differ in their effects on neurotransmitters,
established uses, adverse effects and drug interactions.
All antidepressants that are used for depression are
effective; there is no evidence that one antidepressant is
more effective than another. However, patients may
respond to or tolerate one antidepressant, and not
respond to or tolerate another antidepressant.
What are side effects of antidepressants?

Antidepressants that belong to the same class of
antidepressant produce similar side effects.
Antidepressants may cause withdrawal symptoms if
abruptly discontinued. Withdrawal symptoms
include nausea, vomiting, dizziness, headache,
irritability, sleep disturbance, nightmares, psychosis,
and seizures.
What are side effects of antidepressants?

All antidepressants have a warning about use in children and
adolescents. Antidepressants increased the risk of suicidal
thinking, and suicidal behavior in short-term studies in children
and adolescents with depression and other psychiatric disorders.
Anyone considering the use of antidepressant in a child or
adolescent must balance this risk of suicide with the clinical need
for the drug. Patients who are started on therapy should be closely
observed for clinical worsening, suicidal thoughts or unusual
changes in behavior.
Tricyclic antidepressants (TCAs)
side effects

Tricyclic antidepressants (TCAs) are a class of
antidepressant associated with sedation, dry
mouth, blurred vision, constipation, urinary
retention, and increased pressure in the eye.
Tricyclic antidepressants (TCAs)
side effects

They are also associated with
hypertension, abnormal heart rhythms,
anxiety, insomnia, seizures, headache, rash,
nausea, and vomiting, abdominal cramps, weight
loss, and sexual dysfunction. Tricyclic
antidepressants rarely cause liver failure.
Selective serotonin reuptake
inhibitors (SSRIs) side effects
Selective serotonin reuptake inhibitors (SSRIs) and serotonin/norepinephrine
reuptake inhibitors (SNRIs) are two classes of antidepressants associated
with :
abnormal thinking, agitation, anxiety, dizziness, headache, insomnia, sexual
dysfunction, sedation, tremor, sweating, weight loss, diarrhea, constipation,
dry mouth, rash, and nausea. Rarely, SSRIs have been associated with
hyponatremia (low sodium),hypoglycemia (low blood glucose), and seizures.
Monoamine oxidize inhibitors
(MAOIs) side effects
Monoamine
oxidize inhibitors (MAOIs) are
a class of antidepressant associated with
postural hypotension (feeling faint upon
standing due to decreased blood flow to the
brain
Monoamine oxidize inhibitors
(MAOIs) side effects

high blood pressure, fainting, abnormal heart
rhythm, dizziness, headache, drowsiness,
insomnia, anxiety, constipation, nausea,
diarrhea, sexual dysfunction, weight gain or
weight loss, and edema. Seizures, rash,
blurred vision, and hepatitis are infrequently
associated with MAOIs.
What are the possible drug interactions?
Tricyclic antidepressants (TCAs)
•
Combining tricyclic antidepressants
(TCAs) with clonidine (Catapres) may lead to
dangerous elevations in blood pressure because TCA
may inhibit the antihypertensive effect of clonidine.
What are the possible drug interactions?
Tricyclic antidepressants (TCAs)
•
Combining TCAs with carbamazepine (Tegretol)
may result in lower TCA blood levels and higher
carbamazepine levels, leading to decreased TCA
efficacy or increased carbamazepine toxicity.
What are the possible drug interactions?
Tricyclic antidepressants (TCAs)

TCAs may increase the effects of epinephrine,
norepinephrine and dopamine. Dangerous increases in
blood pressure and abnormal heartbeats may
occur. Cimetidine (Tagamet) may reduce the
breakdown of some TCAs [for
example, amitriptyline (Elavil)] and potentially lead to
increased side effects.
Selective serotonin reuptake
inhibitors (SSRIs) interactions

Selective serotonin reuptake inhibitors (SSRIs) should
not be combined with other drugs that increase brain
serotonin levels [for example, MAOIs,
TCAs, sumatriptan (Imitrex), linezolid(Zyvox), St John's
Wort, amphetamines] because there is a risk of
dangerous adverse effects. The risk of gastrointestinal
bleeding may be increased when SSRIs are combined
with nonsteroidal antiinflammatory drugs (NSAIDs).
Monoamine oxidize inhibitors
(MAOIs) interactions

Monoamine oxidize inhibitors (MAOIs) should not be
combined with other antidepressants or other drugs
that increase serotonin levels [for example,
amphetamines, linezolid (Zyvox), St. Johns Wort,
sumatriptan (Imitrex)]. Such combinations cause
excessive serotonin levels in the brain, which may lead
to confusion, high blood pressure, tremor,
hyperactivity, coma, and death.
Count's

Administration of MAOIs and other antidepressants or
drugs that elevate serotonin should be separated by 14
days. Administration of MAOIs with epinephrine,
norepinephrine, phenylephrine, pseudoephedrine, and
dopamine may lead to hypertensive crisis. MAOIs
interact with tyramine containing foods, resulting in a
hypertensive crisis.

Mood stabilizer:
A mood stabilizer is a psychiatric
medication used to treat mood
disorders characterized by intense and
sustained mood shifts, typically bipolar
disorder.
Uses:
Used to treat bipolar disorder,[1] mood
stabilizers suppress swings
between mania and depression. Moodstabilizing drugs are also used in borderline
personality disorder[2] and schizoaffective
disorder.
Lithium Carbonate

WARNINGS: It is very important to have the
right amount of lithium in your body. Too much
lithium may lead to unwanted effects such as
nausea, diarrhea, shaking of the
hands, dizziness, twitching, seizures, slurred
speech, confusion, or increase in the amount
of urine. Tell your doctor immediately if these
effects occur.
