Amoxapine acts bydecreasing the reuptake of norepinephrine and serotonin (5-HT). Rapidly and almost completely absorbed from the GI tract. Peak plasma concentrations occur within 1-2 hours of oral administration of a single dose.


Is amoxapine a dopamine antagonist?

Amoxapine acts by decreasing the reuptake of norepinephrine and serotonin (5-HT). Rapidly and almost completely absorbed from the GI tract. Peak plasma concentrations occur within 1-2 hours of oral administration of a single dose.

Is amoxapine an antipsychotic drug?

Introduced in 1980, amoxapine was initially promoted as having a faster onset of antidepressant effects compared with other available CAs. Amoxapine inhibits the reuptake of norepinephrine, moderately antagonizes α1-adrenergic and D2 dopamine receptors, and weakly blocks H1 receptors.

Is amoxapine tricyclic or tetracyclic?

Amoxapine is marketed as an antidepressant. However, its in-vitro profile, receptor occupancy and preclinical effects are very similar to atypical antipsychotics. Amoxapine has also shown efficacy as an atypical antipsychotic in open trials.

What is the indication of amoxapine?

Amoxapine is a tricyclic antidepressant that inhibits the uptake of noradrenaline and blocks dopamine D2 receptors, making it potentially useful in the treatment of depressive psychosis when combined with antidepressant and antipsychotic drugs.

How does amoxapine work?

Amoxapine (amoxapine (amoxapine tablets) tablets) is indicated for the relief of symptoms of depression in patients with neurotic or reactive depressive disorders as well as endogenous and psychotic depressions. It is indicated for depression accompanied by anxiety or agitation.

What is the mechanism of action of dopamine antagonists?

Amoxapine is used to treat depression. Amoxapine is in a class of medications called tricyclic antidepressants (TCAs). It works by increasing the amounts of certain natural substances in the brain that are needed to maintain mental balance.

Is amoxapine sedating?

Its mechanisms of action include: blocking postsynaptic mesolimbic dopaminergic receptors in the brain; strong alpha-adrenergic blocking effects decreasing the release of hypothalamic and hypophyseal hormones; competing with histamine for the H1-receptor; muscarinic-blocking effects, and reducing stimuli to the ...

Is Nefazodone an SSRI or SNRI?

As with other tricyclic antidepressants, the mechanism of action of amoxapine probably involves interruption of norepinephrine transmission. Amoxapine also blocks histaminic and cholinergic receptors which account for its mild sedative effects.

What is an alternative to amoxapine?

Nefazodone is a phenylpiperazine compound and is related to trazodone. It has been described as a serotonin antagonist and reuptake inhibitor (SARI) due to its combined actions as a potent antagonist of the serotonin 5-HT2A and 5-HT2C receptors and weak serotonin–norepinephrine–dopamine reuptake inhibitor (SNDRI).

Why are tetracyclic antidepressants not used anymore?

In studies, TCAs like amoxapine have proven to work just as well as other antidepressants (including SSRIs) for treating depression. But, sertraline (Zoloft) is the first-choice medication for the treatment of depression because it has less side effects than amoxapine.
