The aim of the present research was to prepare and evaluate a gastroretentive drug delivery system for metformin HCl, using synthetic and semi-synthetic polymers. The floating approach was applied for preparing gastroretentive tablets (GRT) and these tablets were manufactured by the direct compression method. The drug delivery system comprises of synthetic and semi-synthetic polymers such as po...

Gastroretentive dosage forms (GRDF) has received significant interest in the past few decades as they can improve the limitation of most conventional and oral controlled release drug delivery system related to fast gastric-emptying time. An optimum GRDF system can be defined as a system which retains in the stomach for a sufficient time interval against all the physiological barriers, releases ...

Oral delivery of drugs is by far the most preferable route of drug delivery . Oral-rate controlled drug delivery systems have an important area among novel drug delivery system. But these oral sustained release drug delivery systems suffer greatly due to their short gastric residence time/ gastric emptying time. Whereas prolonged gastric residence increases duration of drug release, reduces dru...

Acne is a common inflammatory skin disease that mainly affects the face, neck, chest and upper back. Treatment depends on severity. Erythromycin has bacteriostatic activity which inhibits the growth of bacteria. They mainly act by binding to the 50s subunits of bacteria, 70s r-RNA complex, and protein synthesis. Erythromycin is also used topically to treat acne. They are used to treat moderate ...

Background. Oxybenzone, a broad spectrum sunscreen agent widely used in the form of lotion and cream, has been reported to cause skin irritation, dermatitis, and systemic absorption. Aim. The objective of the present study was to formulate oxybenzone loaded microsponge gel for enhanced sun protection factor with reduced toxicity. Material and Method. Microsponge for topical delivery of oxybenzo...

Abstract: Objectives: Stavudine has a low half-life of 0.8-1.5 hr and therefore needs recurrent administration to sustain stable beneficial drug plasma levels. In order enhance preserve the level stavudine for round clock, gastroretentive systems (floating low-density formulations that cause buoyancy on gastric fluid in stomach) may prove be advantageous releasing content from matrix tablet res...
