The aim of the present study was to investigate the influence of Eudragit E PO on the drug release mechanism of Eudragit L film coatings applied to eudragot tablets by a dry powder coating technique.

Mebeverine HCl is a water soluble drug commonly used to treat irritable bowel l100-555 by acting directly on the smooth muscles of the colon. Pharm Dev Technol ;8 1: The immobilized thiol groups were preactivated by disulfide bond formation with 2-mercaptonicotinic acid.

The effects of changing the ratio of HPMC to anionic polymers were examined in water and in media with different pH. Hygroscopicity, flow property and disintegration time were improved significantly due to the adsorption and granulation processes. Influence of polymeric subcoats on the drug release properties of tablets powder-coated with pre-plasticized Eudragit L To investigate the use of Carbopol P as a stabilizing agent for supersaturated levels of itraconazole ITZ in neutral pH aqueous media and the resultant effects on oral absorption of ITZ.

Pharm Dev Technol Aug 30;16 4: Pharm Dev Technol ;14 6: It is a solid substance in form of a white powder with a faint characteristic odour. The process involved dissolution of naproxen and Eudragit L in alcohol USP followed by the addition of an aqueous solution containing a surfactant and deaggregating agents. The aim of this study was to characterize the film formation process of Eudragit L dry-powder coatings and to investigate the influence of film additives on melt viscosity and surface tension.
