(proe trip’ ti leen)

Vivactil

PREGNANCY CATEGORY C


Drug Class

TCA (secondary amine)


Therapeutic Actions

Mechanism of action unknown; the TCAs are structurally related to the phenothiazine antipsychotic drugs (eg, chlorpromazine), but in contrast to the phenothiazines, TCAs inhibit the presynaptic reuptake of the neurotransmitters norepinephrine and serotonin; anticholinergic at CNS and peripheral receptors; the relation of these effects to clinical efficacy is unknown.


Indications

  • Unlabeled uses: Treatment of obstructive sleep apnea, prevention of migraine
