Abstract : ABSTRACT Oral delivery of drugs is by far the most preferable route of drug delivery due to the ease of administration, low cost of therapy, patient compliance and flexibility in formulation etc. Oral sustained drug delivery formulations show some limitations connected with the gastric emptying time. Variable and too rapid gastrointestinal transit could result in incomplete drug release from the device into the absorption window leading to diminished efficacy of the administered dose. It is evident from the recent research and patient literature that an increased interest in novel dosage forms that are retained in the stomach for a prolonged and predictable period of time exists today Keywords: SRDDS, Absorption window, gastric emptying time etc.
