Most of the painkillers, if not all, produce hyperacidity and gastric irritation upon oral administration. Curr Drug Deliv Apr;6 2: 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. Drug Dev Ind Pharm Jun;35 6: The purpose eudraigt this research was to improve the hygroscopicity and poor flow properties of the crude dry extract of the seeds of Glinus lotoides and improve the disintegration time of the core-tablets for enteric coated formulation thereof.

MatWeb is intended for personal, non-commercial use. Factorial design was used to evaluate the effect of three formulation factors: Epub Mar The study was aimed to developed and investigate a novel polymer for intestinal drug delivery with improved mucoadhesive properties.

Page 1 of 1. Theophylline pellets were coated with aqueous colloidal dispersions of Eudragit RS 30D containing various amounts of Eudragit L To achieve these aims, yield, incorporation efficiency, ,100-55 size and the distribution of microspheres were determined, and the influence of the inner phase viscosities prepared with different polymer and polymer mixtures on particle size and the distribution of microspheres were evaluated.


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. Rapid preparation of pH-sensitive polymeric nanoparticle with high loading capacity using electrospray for oral drug delivery.
