Novel Aproaches - Mucoadhesive Buccal Drug Delivery System
Among novel drug delivery systems, Buccal mucoadhesive systems have attracted great attention in recent years due to their ability to adhere and remain on the oral mucosa and to release their drug content gradually. Mucoadhesion may be defined as the process where polymers attach to biological substrate or a synthetic or natural macromolecule, to mucus or an epithelial surface. Buccal mucoadhes...
متن کاملFormulation and Evaluation of Mucoadhesive Buccal Films of Enalapril Maleate
Enalapril maleate is used in the treatment of hypertension and angina pectoris. It shows low bioavailability due to high hepatic first pass metabolism. Hence the present work was undertaken to formulate mucoadhesive buccal films of enalapril maleate with an objective to improve therapeutic efficacy, patient compliance and the bioavailability. In the present study ten formulations of mucoadhesiv...
متن کاملDevelopment of Mucoadhesive Buccal Films of Glipizide
For improving bioavailability in controlled release fashion and to circumvent the hepatic first pass effect of glipizide mucoadhesive buccal films of glipizide were prepared by solvent casting technique. Buccal films were prepared using hydroxy propylmethylcellulose, sodium carboxymethylcellulose, carbopol934P and Eudragit RL-100. Films were evaluated for their weight, thickness, surface pH, sw...
متن کاملPreparation and pharmaceutical evaluation of glibenclamide slow release mucoadhesive buccal film
Buccal mucoadhesive systems among novel drug delivery systems have attracted great attention in recent years due to their ability to adhere and remain on the oral mucosa and to release their drug content gradually. Buccal mucoadhesive films can improve the drug therapeutic effect by enhancement of drug absorption through oral mucosa increasing the drug bioavailability via reducing the hepatic f...
متن کاملDevelopment of mucoadhesive buccal films from rice for pharmaceutical delivery systems.
The aim of this work was to investigate the suitable rice varieties for developing pharmaceutical buccal films. Two rice varieties with extreme difference in amylose content were used. Rice powders were chemically modified to yield the carboxymethyl rice prior to film preparation. Scanning electron microscope (SEM) and X-ray diffractometer (XRD) were used to investigate the solid structure of r...
