The effect of venlafaxine on labor and delivery in humans is unknown. Retrieved 20 June 2007. Concomitant administration of cimetidine and venlafaxine in a steady-state study for both drugs resulted in inhibition of first-pass metabolism of venlafaxine in 18 healthy subjects. The oral clearance of venlafaxine was reduced by about 43%, and the exposure AUC and maximum concentration C max of the drug were increased by about 60%. However, coadministration of cimetidine had no apparent effect on the pharmacokinetics of ODV, which is present in much greater quantity in the circulation than venlafaxine. The overall pharmacological activity of venlafaxine plus ODV is expected to increase only slightly, and no dosage adjustment should be necessary for most normal adults. However, for patients with pre-existing hypertension, and for elderly patients or patients with hepatic dysfunction, the interaction associated with the concomitant use of venlafaxine and cimetidine is not known and potentially could be more pronounced. Therefore, caution is advised with such patients. galantamine

CYP2D6 Inhibitors: In vitro and in vivo studies indicate that Venlafaxine is metabolized to its active metabolite, ODV, by CYP2D6, the isoenzyme that is responsible for the genetic polymorphism seen in the metabolism of many antidepressants. Therefore, the potential exists for a drug interaction between drugs that inhibit CYP2D6-mediated metabolism and Venlafaxine. However, although imipramine partially inhibited the CYP2D6-mediated metabolism of Venlafaxine, resulting in higher plasma concentrations of Venlafaxine and lower plasma concentrations of ODV, the total concentration of active compounds Venlafaxine plus ODV was not affected. Venlafaxine and ODV have no significant affinity for muscarinic-cholinergic, H1-histaminergic, or α1 adrenergic receptors in vitro. Pharmacologic activity at these receptors is hypothesized to be associated with the various anticholinergic, sedative, and cardiovascular effects seen with other psychotropic drugs.

Serotonin syndrome requires immediate medical attention, including withdrawal of the serotonergic agent and supportive care. Venlafaxine hydrochloride extended release capsules for extended periods should periodically re-evaluate the long-term usefulness of the drug for the individual patient. The mechanism of the antidepressant action of venlafaxine in humans is believed to be associated with its potentiation of neurotransmitter activity in the CNS. Preclinical studies have shown that venlafaxine and its active metabolite, O-desmethylvenlafaxine ODV are potent inhibitors of neuronal serotonin and norepinephrine reuptake and weak inhibitors of dopamine reuptake. Venlafaxine and ODV have no significant affinity for muscarinic, histaminergic, or α-1 adrenergic receptors in vitro. Pharmacologic activity at these receptors is hypothesized to be associated with the various anticholinergic, sedative, and cardiovascular effects seen with other psychotropic drugs.
