Purposes: Propranolol HCl is a beta blocker commonly used worldwide; however, it shows a low bioavailability due to its extensive first-pass metabolism. To solve this problem, a novel drug delivery system such as buccoadhesive system might be helpful. The aim of the present investigation is to prepare the buccoadhesive tablet of propranolol HCl using different mucoadhesive polymers. Method: Buc...

Objective: The Losartan potassium mucoadhesive buccal tablet were prepared using mucoadhesive polymers such as Carbopol 940P, pectin, sodium CMC, Sodium alginate, HPMC K4M, HPMC K15M and HPMC K100M in alone and in combination as release retarding agent to prolong the drug release and to avoid first pass metabolism. Methods: The mucoadhesive buccal tablets were prepared by direct compression met...

Glipizide is mainly absorbed in the proximal areas of the gastrointestinal tract. The purpose of this study was formulation and evaluation of mucoadhesive films to prolong the stay of drug in its absorption area. Glipizide was formulated in a mucoadhesive film that could be retained in the stomach for prolonged intervals. Polymeric films were designed with various compositions of hydroxypropyl ...

The aim of this study was to investigate the rheological behavior and mucoadhesive nature of saliva substitutes, by incorporating various mucoadhesive polymers into an artificial saliva pump spray formulation. For this purpose various mucoadhesive polymers including cellulosic polymers in the range of 0.1-1.0% and Carbomers such as C974p, C971, C934p and C971 in the range of 0.01-0.1% were adde...

This paper describes the preparation of new bilayered device comprising a drug containing mucoadhesive layer and a drug free backing layer. Bilaminated films were produced by a casting/ solvent evaporation technique. The mucoadhesive layer was composed of mixture of drug and sodium alginate with or without carbopol 934 P, and backing layer was made of ethyl cellulose. The double layer structure...

Oral drug administration has been the predominant route for drug delivery due to the ease of administration, patient convenience and flexibility in formulations. Mucoadhesive tablets of Cephalexin monohydrate were prepared with an objective to increase the bioavailability by minimizing the first pass metabolism and also to reduce the frequency of administration. Carbopol 934p as a primary polym...

The aim of the present study was to formulate and evaluate nystatin containing thermosensitive mucoadhesive gel for vaginal drug delivery to achieve prolonging the residence time, sustained drug release, enhancing efficacy, decreasing recurrence, and increasing patient compliance in the treatment for vaginal candidiasis. Here nystatin (1%) as a model drug. A 3 full factorial design was employed...

This study describes the effect of Guar gum and chitosan on formulation of mucoadhesive drug delivery system of itraconazole. Mucoadhesive strength, Drug content, Hardness, Friability, Weight variation, Moisture content and accelerated stability studies were performed to study the effect of polymers on prepared mucoadhesive tablets. Results of the present study clarified the potential of guar g...
