COTAB EN
Description
Cotab EN Manufacturer in Ahmedabad
We offer Cotab EN Enteric Coating Powder, a high-performance pharmaceutical coating system specially developed for enteric protection applications. Cotab EN is formulated using Methacrylic Acid Co-polymer Type A technology to provide effective gastric protection and controlled drug release in intestinal conditions.
The coating system acts as a protective polymeric barrier over tablets, preventing premature drug release in the acidic environment of the stomach. It enables the active pharmaceutical ingredient to remain protected from gastric acids and allows targeted release at intestinal pH conditions.
Cotab EN is designed for organic solvent-based coating applications and can be reconstituted at 8.0% to 9.0% concentration using different solvent systems such as IPA/MDC, IPA/Water, or IPA/Acetone combinations.
With recommended coating weight gain of 7.0% to 8.0%, Cotab EN provides uniform film formation, excellent coating adhesion, and reliable enteric protection for pharmaceutical formulations.
