the objective of this study was to formulate and evaluate the drug-polymer interaction of mefenamic acid (ma) using two polymers with different characteristics as ethylcellulose (ec) and/or cellulose acetate phthalate (cap). microspheres were prepared by the modified emulsion solvent evaporation (mese). the effect of drug-polymer interaction was studied for each of microspheres. important param...

The aim of present study was to formulate and evaluate the loxoprofen loaded Sustained release microspheres by emulsion solvent evaporation technique. Ethylcellulose, a biocompatible polymer is used as the retardant material. The effects of process conditions such as drug loading, polymer type and solvent type on the characteristics of microspheres were investigated. The prepared microspheres w...

Diclofenac sodium is a Non-Steroidal Anti-inflammatory Drug, active against relief from pain and inflammation. The main objective of this research work was to prepare Ethyl Cellulose microsphere loaded with Diclofenac and invitro drug release study. In the present study, emulsion Solvent Evaporation Method is used for preparing microsphere. The polymer (EC) and drug (Diclofenac Sodium) was diss...

The present study involves preparation and evaluation of gastric-mucoadhesive microparticles with Metformin Hydrochloride as model drug for prolongation of gastric residence time. The microparticles were prepared by the emulsification solvent evaporation technique using polymers of Carbomer 934p (CP) and Ethylcellulose (EC). The microparticles were prepared by emulsion solvent evaporation metho...

Naproxen sodium is a nonsteroidal anti-inflammatory drug (NSAID) with analgesic antipyretic properties. In this research work, naproxen was encapsulated by solvent-evaporation technique using kollidon® SR as coating polymeric material to prolong the therapeutic duration of drug. Four different concentrations talc were used additives see changes in release pattern from compressed microcapsules. ...

Objective. The purpose of the recent study was to prepare and estimate sustained release of Ethylcellulose (300 cps) and Eudragit (RS 100 and RL 100) microparticles containing Propranolol hydrochloride used as a treatment of cardiovascular system, especially hypertension. Method. Propranolol hydrochloride was microencapsulated with different polymers (Ethylcellulose, Eudragit RS, and Eudragit R...

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 diffe...
