What is Effexor Antidepressant

Effexor is a brand name for Venlafaxine. Effexor is an antidepressant in a group called selective serotonin and norepinephrine reuptake inhibitors or SSNRIs.

Effexor is used to treat major depressive disorder, generalized anxiety disorder and panic disorder in adults. Venlafaxine affects chemicals in the brain that may become unbalanced and cause depression. Venlafaxine is contraindicated in children and adolescents because it can increase suicidal thoughts, attempts, and self-harm.

Effexor was the sixth most commonly prescribed antidepressant on the U.S. retail market, with 17.2 million prescriptions in the year 2007.

Effexor (Venlafaxine) is a structurally novel antidepressant for oral administration.

Effexor is a white to off-white crystalline solid that has a solubility of 572 mg/mL in water. Effexor is sold in orange colored tablets which have pentagonal shape, containing 25, 37.5, 50, 75 or 100 mg of Venlafaxine. Nonactive ingredients are cellulose, iron oxides, lactose, magnesium stearate and sodium starch glycolate.

Venlafaxine XR / Effexor XR

Effexor eXtended Release is chemically the same as normal Venlafaxine. Effexor XR is formulated as an extended-release capsule for a once-a-day oral administration.

Some researchers have shown that the extended release formula has low incidence in patients that get nausea as an adverse effect. Some of these patients stop their treatment due to nausea problems. Just like Prozac medication, EffexorXR release is controlled by diffusion through the coating membrane on the spheroids and is not pH dependent.
