Formulation and Evaluation of Gastroretentive Floating Microballoons of Anti diabetic drug

The objective of present investigation is to design a sustained release floating microballoons of Metformin HCl using two polymers of different permeability characteristics Cellulose Acetate Butyrate (MW of 16,000) and Eudragit RS 100 (MW of 150,000) using the oil-in-oil emulsion solvent evaporation method. The prepared microballoons were studied for drug release behavior in simulated gastric f...

Formulation and in vitro characterization of cefpodoxime proxetil gastroretentive microballoons

BACKGROUND AND THE PURPOSE OF THE STUDY The objective of the present work was to improve bioavailability of cepodoxime proxetil through gastroretentive microballoon formulation. METHODS Microballoons of cefpodoxime proxetil were formulated by solvent evaporation and diffusion method employing hydroxypropylmethyl cellulose (HPMC) and ethyl cellulose (EC) polymers and characterized for particle...

Formulation and Evaluation of Glipizide Hollow Microballoons for Floating Drug Delivery

The present investigation was aimed to formulate and evaluate the gastro-retentive floating microballoons of glipizide using hydrophilic polymers hydroxypropyl methylcellulose (HPMC) and Eudragit RS100 (RS 100) by emulsion solvent evaporation technique. The floating microballoons were evaluated using micromeritic properties, buoyancy, in vitro drug release, scanning electron microscopy and stab...
