Mucoadhesive durg delivery systems are among novel drug delivery systems that due to their ability to adhere and remain on the mucosal surfaces and a show and sustained release of their drug contect have attracted special attention in recent years.the aim of this study was to evaluate the effect of four different important factors on the  mucoadhesive strength of a few  mucoadhesive polymers.am...

INTRODUCTION Metformin is an oral anti-diabetic drug in the biguanide class. The goal of this study was to develop gastric-retentive MH discs in order to prolong the retention of drug in gastric mucosa. METHODS Two groups of metformin hydrochloride (MH) mucoadhesive gastroretentive discs were prepared: (a) bilayered discs prepared by direct compression of powders containing polymers as Carbop...

objective (s): mucoadhesive disc is one of the various routes of drug delivery for curing buccal disease.materials and methods:everydiscs containing 70 mg stem bark extract of ziziphus jujuba were formulated  by using carbopol 934, pvp k30 and gelatin as polymers. discs were made by granulation  and direct compression. discs were standardized based on the total phenol.  properties such as in vi...

PURPOSE Sumatriptan succinate (Sum) is a Serotonin 5- HT1 receptor agonist, used in the treatment of migraine. It is absorbed rapidly but incompletely when taken orally and underwent first - pass metabolism, resulting in a low bioavailability of about 15%. The aim was to design mucoadhesive buccal discs and sublingual films of Sum and metoclopramide (Met) combined to improve their bioavailabili...

Objective: The objectives of the present work were to carry out thiol-modification (i.e., thiolation) fenugreek polysaccharide (FP) and assess synthesized thiolated product (TFP) as a mucoadhesive excipient in designing formulations (metronidazole gels metronidazole buccal discs). Methods: Extracted CG was thiol-modified via an esterification reaction by utilizing thioglycolic acid with acidic ...
