Venlafaxine hydrochloride (C17H27NO2·HCl) is a white to off-white crystalline powder that dissolves easily in water. Its high solubility makes extended-release formulation the key technical challenge.
Pharmaceutical companies use it mainly in extended-release capsules containing coated pellets and in extended-release tablets, as well as in immediate-release tablets. Similarly, related APIs in our range include Duloxetine hydrochloride, Sertraline Hydrochloride and Paroxetine Hydrochloride.
