The objective of the present study was to develop floating microspheres of cefpodoxime proxetil in order to achieve an extended retention in the upper GIT, which may result in enhanced absorption and thereby improved bioavailability. The microspheres were prepared by non-aqueous solvent evaporation method using polymers such as hydroxyl propyl methyl cellulose (HPMC K 15 M), ethyl cellulo...

The main aim of the study was to develop and statistically optimize the proniosomal gel for enhanced transdermal delivery using 3(2) factorial designs to investigate the influence of both non-ionic surfactant and cholesterol to maximize the entrapment efficiency and flux. The concentration of non-ionic surfactant and cholesterol were taken as independent variables, while entrapment efficiency a...

Article history: Received on: 30/08/2013 Revised on: 03/10/2013 Accepted on: 15/10/2013 Available online: 31/10/2013 Azathioprine loaded gelatin microspheres were formulated to control/target drug release in an arthritic joint by magnetic force or intra-articular injection. Glutaraldehyde cross linked microspheres were characterized for drug loading, entrapment efficiency, gas chromatography, m...

The objective of this study was to microencapsulate the anti-inflammatory drug (naproxen) to provide controlled release and minimizing or eliminating local side effect by avoiding the drug release in the upper gastrointestinal track. Naproxen was microencapsulated with lipid-like carnauba wax, hydrogenated castor oil using modified melt dispersion (modified congealable disperse phase encapsulat...

The purpose of this research was to established new polysaccharide for the colon targeted drug delivery system, its formulation and in vitro and in vivo evaluation. Microspheres containing chitosan and bora rice were prepared by simple emulsification phase separation technique using glutaraldehyde as cross linking agent and model drug used was glipizide. Results of trial batches indicated that ...

The aim of this study was to develop and optimise a saikosaponin a and saikosaponin d compound liposome (SSa-SSd-Lip) formulation with reduced hemolysis and enhanced bioavailability. A screening experiment was done with Plackett-Burman design, and response surface methodology of five factors (EPC/SSa-SSd ratio, EPC/Chol ratio, water temperature, pH of PBS, and ultrasound time) was employed to o...

The purpose of this research was to formulate and systematically evaluate in vitro performances of chitosan microspheres containing Mitomycin-C. Chitosan microspheres containing Mitomycin-C were prepared by simple emulsification phase separation technique using glutaraldehyde as a cross-linking agent. Results of preliminary trials indicate that volume of cross-linking agent, time for cross-link...

BACKGROUND The purpose of this study was to develop a transdermal ligustrazine patch containing a stable formulation and with good entrapment efficiency, release rate, and transdermal absorption. METHODS Ligustrazine ethosomes were prepared by ethanol injection-sonication, with entrapment efficiency as an indicator. Using acrylic resin as the primary constituent, the ligustrazine ethosome pat...

Topical beta-blocking agents are nowadays the drugs of choice as these have few ocular and systemic side effects. In the present study some selected beta blockers (PP-24, PP-34, PP-41, PP-48, PP-50), synthesized using 4-hydroxybenzaldehyde and isovanillin were encapsulated into niosomes possessing a high drug entrapment efficiency in order to be used as ophthalmic carriers for topical ocular tr...
