The objective of research was to explore the suitability of lipids like compritol 888 ATO and stearic acid as release retardant to develop sustained release (SR) tablets. The SR micromatrices of lipid (s) and glipizide were prepared (LM1- LM6) as intermediate product by fusion method and assessed for various pharmacotechnical properties. Micromatrices were formulated as SR tablets (F1-F6) by di...
متن کاملFormulation and Characterization of Mucoadhesive Microspheres Using Verapamil Hydrochloride as Model Drug
The objective of the current investigation is to reduce dosing frequency and improve patient compliance by designing and systematically evaluating sustained release microspheres of verapamil. Frequent administration and variable low bioavailability (40-60%) after oral administration are problems of conventional dosage forms of verapamil can be attenuated by designing it in the form of mucoadhes...
