Comparison of Microencapsulation by Emulsion-Solvent Extraction/Evaporation Technique Using Derivatives Cellulose and Acrylate-Methacrylate Copolymer as Carriers
BACKGROUND Microencapsulation is a useful method to prolong a drug release from dosage forms and to reduce its adverse effect (1) among various available methods. The microencapsulation of hydrophilic active ingredients requires the use of a polar dispersing phase such as a mineral oil. Acetone/paraffin systems are conventionally used. OBJECTIVES The current study aimed to investigate two dif...

متن کاملMicroencapsulation of Zidovudine by Double Emulsion Solvent Diffusion Technique using Ethylcellulose
Zidovudine-ethylcellulose microspheres were prepared by water-in-oil-in-oil double emulsion solvent diffusion method. Spherical free flowing microspheres having an entrapment efficiency of 32-54% were obtained. The effect of polymer-drug ratio, surfactant concentration for secondary emulsification process, volume of processing medium and stirring speed of secondary emulsification process was ev...
متن کاملFabrication and in Vitro Evaluation of Metformin Entrapped Sustained Release Ammonio Methacrylate Copolymer Microparticles Prepared by Non-aqueous Emulsion Solvent Evaporation Technique
Metformin hydrochloride is an orally administered first line drug which commonly used in the management of type-2 diabetes. To overcome the side effects of it due to high/repeated dose and patient inconvenience, the sustained release microparticles of metformin loaded RS100 were developed. The method used to prepared microparticles was novel oil in oil technique. Obtained microparticles were ch...
