A REVIEW ON TABLET MODIFIED DRUG DELIVERY AND COATING TECHNOLOGY

Abstract

Tablets are one of the most convenient and widely used solid dosage forms. A tablet is a compressed dosage form that may or may not contain an active drug. Coating is defined as a tablet or granule coated with a dry outer film to achieve specific goals such as masking the taste of the desired dosage form or protecting it from environmental conditions. The coating types are sugar coating, film coating, gelatin coating, enteric coating and compression coating technology. These devices are usually used to cover the outer layer of the tablet with a thin film that acts as a coating material. The purpose of the entire film was to prevent physical or chemical damage to the tablet and mask unpleasant odors, smells and tastes. Polymers play an important role in coating technology; are often used as flavor maskers and film-forming agents to modify the delivery of dosage forms.
