What is Venlafaxine

Venlafaxine affects chemicals in the brain that may be unbalanced in people with depression. It is used to treat major depressive disorder, anxiety and panic disorder. Venlafaxine tablets, USP is a structurally novel antidepressant for oral administration.

Venlafaxine is an antidepressant belonging to a group of drugs called selective serotonin and norepinephrine reuptake inhibitors (SSNRIs). Venlafaxine is known to be a serotonin-noridipyrfine (SNRI) reversal inhibitor. This helps by restoring the balance of some of the natural substances (serotonin and noramidurfine) in the brain.

Drugs that may interact with Venlafaxine 

Many medicines can interact with venlafaxine. Not all possible interactions are listed here. Tell your doctor about all your current drugs and any you start or stop using, especially:

any other antidepressant;

tramadol;

cimetidine;

tryptophan (sometimes called L-tryptophan);

St. John's wort;

a blood thinner - warfarin, Coumadin, Jantoven;

medicine to treat mood disorders, thought disorders, or mental illness - buspirone, lithium, and many others; or

migraine headache medicine - sumatriptan, zolmitriptan, and others.

This list is not complete and many other drugs can interact with venlafaxine.

Cimetidine

Co-administration of cimetidine and venlafaxine in a sustained study for both drugs led to the inhibition of the first metabolism in venlafaxine in 18 healthy individuals. Oral secretion of venlafaxine is reduced by about 43%, with a 60% increase in AUC and maximal drug concentration (Cmax). However, cimetidine synchronization has apparent effects on the pharmacokinetics of ODV, which is much more circulating, than venlafaxine. It is expected that the active physical activity of venlafaxine with ODV will only slightly increase and for most adults, dosage adjustment should not be necessary.

Under stable conditions for venlafaxine, a daily dose of 150 mg per day, only a dose of 10 mg of diazepam does not appear to affect medication on venlafaxine or ODV in 18 healthy male patients. Venlafaxine also has no effect on the pharmacokinetics of diazepam or its active metabolite, desmethyldiazepam, or the psychosocial and psychological effects of diazepam.

Alcohol

Single dose of ethanol (0.5 g / kg) does not affect venlafaxine or ODV when Venlafaxine is taken at 150 mg / day in 15 healthy male patients. In addition, the administration of venlafaxine in a stable diet did not exceed the psychological and psychological effects of ethanol in these same individuals when not receiving venlafaxine.
