Abstract

The present disclosure relates to a delayed controlled release composition of at least one form of venlafaxine. According to the disclosure a delayed controlled release composition of venlafaxine hydrochloride is provided by a blend of polymers in the core formulation. The core formulation having extended release polymers is coated with a non-permeable polymer blend formed of a water in-soluble polymer and an enteric coating polymer, which does not release the active drug in either acid or base for up to about 4 hours. Upon disintegration of the non-permeable coating the active drug is released in a sustained manner due to the polymers within the core formulation. The delayed release prevents the substantial release of venlafaxine into the stomach.
