Desvenlafaxine is an extended-release tablet for oral administration that contains desvenlafaxine succinate, a structurally novel SNRI for the treatment of MDD. Desvenlafaxine (O-desmethylvenlafaxine) is the major active metabolite of the antidepressant venlafaxine, a medication used to treat major depressive disorder. Desvenlafaxine is designated RS-4-[2-dimethylamino-1-(1-hydroxycyclohexyl)ethyl]phenol and has the empirical formula of C16H25NO2 (free base) and C16H25NO2•C4H6O4•H2O (succinate monohydrate). Desvenlafaxine succinate monohydrate has a molecular weight of 399.48. The structural formula is shown below. [Image] Desvenlafaxine succinate monohydrate is a white to creamish crystalline powder that is soluble in water. The solubility of desvenlafaxine succinate monohydrate is pH dependent. Its octanol: aqueous system (at pH 7.0) partition coefficient is 0.21. Desvenlafaxine is formulated as an extended-release tablet for once-a-day oral administration. Each film-coated tablet contains 76 mg or 152 mg of desvenlafaxine succinate monohydrate equivalent to 50 mg or 100 mg of desvenlafaxine, respectively. Inactive ingredients for the 50 mg tablet consist of colloidal silicon dioxide, hypromellose, iron oxide red, iron oxide yellow, magnesium stearate, microcrystalline cellulose, polyethylene glycol, polyvinyl alcohol, talc and titanium dioxide. Inactive ingredients for the 100 mg tablet consist of colloidal silicon dioxide, FD&C yellow #6 aluminum lake, hypromellose, iron oxide red, magnesium stearate, microcrystalline cellulose, polyethylene glycol, polyvinyl alcohol, talc and titanium dioxide.
