Enteric-coated tablets protect active pharmaceutical ingredients from gastric acid and enable site-specific drug release within the gastrointestinal tract. Learn about their purpose, coating-film characteristics, suitable APIs, and commonly used enteric polymers including CAP, HPMCP, HPMCAS, PVAP, and Eudragit.

Learn what nitrosamines are, how they form in APIs and excipients, the associated risks, and current regulatory limits for pharmaceutical raw materials. 

An in-depth analysis of matrix systems in the formulation of sustained-release tablets. Explore drug release mechanisms, excipient classifications (hydrophilic, inert, and lipid), and the advanced benefits of lipid matrix technologies in modern pharmaceutical development.

MCC is produced through the acid hydrolysis of cellulose under high temperature and pressure.

Tablets are solid unit-dose dosage forms with a defined geometric shape. Each individual unit is formulated to contain a precise amount of one or more active pharmaceutical ingredients (APIs). Tablets are manufactured by applying mechanical compression to a blend of granules or fine powders, with or without excipients, using specialized tablet compression equipment.

This article details the polymer nature of ion exchange resins (IER) and their reversible complexation mechanism for effective taste masking. It highlights their safety, compatibility, and wide applications in suspensions, powders, chewable tablets, and ODTs.
