Layered Tablets: A Novel Oral Solid Dosage Form

Oral solid dosage forms hold a predominant position in the drug delivery system. Tablets are the most widely used and convenient dosage form. Due to their ease of manufacturing, the minimum cost of production, easy handling and storage, and better stability, tablets are most preferred. Patients who are prescribed more than one drug are in a situation to consume multiple tablets. To minimize the counts, one or more drugs are cast into layers to form a single tablet, thus called layered tablets. Layered tablets tend to improve patient compliance and reduce the cost of production by half. Layers can be of multiple drugs or the same drug at different doses or drugs with release enhancers or drugs with fillers. Layered tablets hold a greater potential with better patient outcomes as well as stay production-friendly
