Venlafaxine tablets is indicated for the treatment of major depressive disorder.

The efficacy of venlafaxine tablets, in the treatment of major depressive disorder was established in 6 week controlled trials of adult outpatients whose diagnoses corresponded most closely to the DSM-III or DSM-III-R category of major depression and in a 4 week controlled trial of inpatients meeting diagnostic criteria for major depression with melancholia

A major depressive episode implies a prominent and relatively persistent depressed or dysphoric mood that usually interferes with daily functioning (nearly every day for at least 2 weeks); it should include at least 4 of the following 8 symptoms: change in appetite, change in sleep, psychomotor agitation or retardation, loss of interest in usual activities or decrease in sexual drive, increased fatigue, feelings of guilt or worthlessness, slowed thinking or impaired concentration, and a suicide attempt or suicidal ideation.

The efficacy of venlafaxine hydrochloride extended-release capsules in maintaining an antidepressant response for up to 26 weeks following 8 weeks of acute treatment was demonstrated in a placebocontrolled trial. The efficacy of venlafaxine tablets in maintaining an antidepressant response in patients with recurrent depression who had responded and continued to be improved during an initial 26 weeks of treatment and were then followed for a period of up to 52 weeks was demonstrated in a second placebo-controlled trial (see Clinical Trials). Nevertheless, the physician who elects to use venlafaxine tablets / extended-release capsules for extended periods should periodically re-evaluate the long-term usefulness of the drug for the individual patient.

The exact mechanism of action of venlafaxine is unknown, but appears to be associated with the its potentiation of neurotransmitter activity in the CNS. Venlafaxine and its active metabolite, O-desmethylvenlafaxine (ODV), inhibit the reuptake of both serotonin and norepinephrine with a potency greater for the 5-HT than for the NE reuptake process. Both venlafaxine and the ODV metabolite have weak inhibitory effects on the reuptake of dopamine but, unlike the tricyclics and similar to SSRIs, they are not active at histaminergic, muscarinic, or alpha(1)-adrenergic receptors.
Increased risk of serotonin syndrome with TCA, SSRI, SNRI, lithium, sibutramine, tramadol. May increase serum levels with CYP3A4 inhibitors (e.g. ketoconazole, atazanavir, clarithromycin). May increase serum levels of haloperidol. May decrease serum levels of indinavir. May increase bleeding risk with aspirin, NSAIDs, warfarin and other anticoagulants.
Changes in behaviour, suicidal ideation, agitation, tremor, nervousness, anxiety, insomnia, confusions, abnormal dreams, HTN, nausea, headache, asthenia, somnolence, dizziness, dry mouth, vomiting, constipation, diarrhoea, dyspepsia, abdominal pain, anorexia, sexual dysfunction, urinary frequency, visual disturbances, mydriasis, vasodilatation, paraesthesia, hypertonia, chills or fever, palpitations, wt gain or loss, arthralgia, myalgia, tinnitus, pruritus, dyspnoea, yawning, rashes, sweating, increased serum cholesterol, may impair platelet aggregation.
Treatment Of Pregnant Women During The Third Trimester
Neonates exposed to venlafaxine tablets, USP, other SNRIs, or SSRIs, late in the third trimester have developed complications requiring prolonged hospitalization, respiratory support, and tube feeding. When treating pregnant women with venlafaxine tablets during the third trimester, the physician should carefully consider the potential risks and benefits of treatment.
History of MI or unstable cardiac disease, seizure; hypomania or mania, increased intraocular pressure or at risk of acute narrow-angle galaucoma, at risk of bleeding. Renal and hepatic impairment. Gradual dose reduction is recommended rather than abrupt withdrawal. Pregnancy and lactation. Patient Counselling May impair ability to drive or operate machinery.
Dosage For Patients With Hepatic Impairment: Given the decrease in clearance and increase in elimination half-life for both venlafaxine and ODV that is observed in patients with hepatic cirrhosis and mild and moderate hepatic impairment compared to normal subjects, it is recommended that the total daily dose be reduced by 50% in patients with mild to moderate hepatic impairment. Since there was much individual variability in clearance between subjects with cirrhosis, it may be necessary to reduce the dose even more than 50%, and individualization of dosing may be desirable in some patients.

Dosage For Patients With Renal Impairment: Given the decrease in clearance for venlafaxine and the increase in elimination half-life for both venlafaxine and ODV that is observed in patients with renal impairment (GFR = 10 to 70 mL/min) compared to normals, it is recommended that the total daily dose be reduced by 25% in patients with mild to moderate renal impairment. It is recommended that the total daily dose be reduced by 50% in patients undergoing hemodialysis. Since there was much individual variability in clearance between patients with renal impairment, individualization of dosing may be desirable in some patients.

Serotonin-norepinephrine reuptake inhibitor (SNRI)
Symptoms: Sweating, dizziness, somnolence, mydriasis, convulsions, vomiting, ECG changes, cardiac arrhythmias and seizures.

Management: Symptomatic and supportive treatment. Ensure adequate airway, oxygenation and ventilation. Initiate gastric lavage immediately after ingestion. Admin activated charcoal to reduce absorption. Monitor cardiac rhythm and vital signs.

Store between 20-25° C.
