Tablet coating plays a vital role in pharmaceutical manufacturing. It improves product stability, enhances tablet appearance, supports controlled drug release, and protects sensitive active pharmaceutical ingredients from external environmental conditions. While aqueous coating systems are widely preferred because of their safety and environmental advantages, they are not always suitable for formulations that react negatively to moisture exposure. In such cases, pharmaceutical coating processes require alternative solvent systems capable of delivering reliable coating performance without compromising formulation stability. Moisture sensitive drug formulations present unique manufacturing challenges. Exposure to water during coating may trigger degradation of the active ingredient, reduce shelf life, alter tablet hardness, or create coating defects such as cracking and poor adhesion. These risks can affect both therapeutic performance and regulatory compliance. As a result, non aqueous ...

Sustained release medicines have become increasingly important in modern pharmaceutical treatment. These formulations are designed to release active ingredients gradually over time instead of delivering the full dose immediately. The result is better therapeutic control, reduced dosing frequency, and improved patient convenience. To achieve this controlled drug release, pharmaceutical scientists rely on carefully selected polymers, coating technologies, and processing solvents. Among these solvents, acetone continues to play a highly valuable role. Acetone is widely recognised for its strong solvency and rapid evaporation characteristics. It dissolves many pharmaceutical polymers quickly and efficiently. This makes it particularly useful during the preparation of coating solutions and polymer matrices used in sustained release systems. Polymers such as ethyl cellulose, cellulose acetate, and acrylic compounds require reliable solvent systems to form stable structures. Acetone helps cre...
