Formulation and Evaluation of Controlled Release Floating Microballoons of Stavudine

Formulation and Evaluation of Controlled Release Floating Microballoons of Stavudine.

The aim of this study was to formulate and evaluate stavudine floating microballoons for controlled drug release. Initially, the drug-loaded low-density granular pellets were prepared with hydroxypropyl methylcellulose E5 grade and by using isopropyl alcohol as a granulating fluid. Further, the low-density granular pellets were subjected to microencapsulation by an emulsion evaporation techniqu...

Formulation and in-vitro evaluation of floating microballoons of indomethacin.

Objective of present study involves preparation and evaluation of floating microballoons of indometacin as a model drug, to increase its residence time in the stomach without contact with the mucosa. The microballoons were prepared by the emulsion solvent diffusion technique using different ratio of acrylic polymers (Eudragit RS100 and Eudragit S 100) as carriers. The yield of microballoons was...

Formulation and Evaluation of Gastroretentive Floating Microballoons of Norfloxacin

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 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...
