Fast dissolving tablet

Fast dissolving tablets have emerged as a popular dosage form, particularly beneficial for pediatric and geriatric patients facing challenges such as dysphagia or hand tremors. These tablets dissolve quickly in saliva without needing water, enhancing compliance and effectiveness of therapy. They offer advantages like easy portability, accurate dosing, and improved bioavailability. Various technologies, including spray drying and melt granulation, have been developed for their manufacturing. This review provides comprehensive information on fast dissolving tablets, covering their definition, advantages, limitations, challenges, and available formulations. The design of an oral drug delivery system prioritizes convenience in administration and improved patient compliance, making it the preferred route of drug delivery despite certain drawbacks. Over the last decade, there has been a growing demand for Fast Disintegrating Tablets (FDTS), turning this field into a rapidly expanding area within the pharmaceutical industry. The formulation’s popularity and effectiveness have led to the development of various FDT technologies. These technologies aim to achieve rapid tablet disintegration and mouth dissolution within five seconds, eliminating the need for chewing or water intake. This characteristic is particularly advantageous for populations such as pediatrics, geriatrics, and patients facing difficulties in swallowing conventional tablets and capsules. The formulation of an easily administrable dosage form, considering challenges like swallowing difficulties and low patient compliance, has driven the creation of orally disintegrating tablets. Traditional preparation methods include spray drying, freeze drying, direct compression, molding, and sublimation. In addition, new technologies have been devised to enhance the production of orodispersible tablets.
