This study was performed to achieve sustained-release Ibuprofen matrix tablets with a zero-order release kinetic while most of the previous formulations have shown Higuchi release kinetic. Considering the results from previous studies, ethyl cellulose, Carbopol 934P, Carbopol 974P, and Pemulen TR-1 were used at different amounts for preparation of the tablets by direct compression. The release ...

PURPOSE To investigate the suitability of an SCMC (sodium carboxymethyl cellulose/polyethylene glycol 400/carbopol 934P) and an HPMC (hydroxypropylmethyl cellulose/polyethylene glycol 400/carbopol 934P) films as drug vehicle for buccal delivery. METHODS The mechanical and in vitro bioadhesive strength properties of the films were investigated using texture analyzer equipment, while swelling b...

Omeprazole pellets containing mucoadhesive tablets were developed by direct punch method. Three mucoadhesive polymers namely hydroxypropylemethylcellulose K4M, sodium carboxy methylcellulose, carbopol-934P and ethyl cellulose were used for preparation of tablets which intended for prolong action may be due to the attachment with intestinal mucosa for relief from active duodenal ulcer. Mucoadhes...

Purpose of Study: In the present study, an attempt was made to design and evaluate buccoadhesive bilayer tablets of granisetron hydrochloride (an anti-emetic drug), in order to overcome bioavailability problems, to reduce dose dependent side effects and frequency of administration. Method: Bilayer buccal tablets containing the drug were prepared by direct compression method using combination of...

A new oral drug delivery system was developed utilizing both the concepts of controlled release and mucoadhesiveness, in order to obtain a unique drug delivery system which could remain in stomach and control the drug release for longer period of time. Captopril microcapsules were prepared with a coat consisting of alginate and a mucoadhesive polymer such as hydroxy propyl methyl cellulose, car...

In present study, mucoadhesive vaginal tablet of sertaconazole was designed using a combination of mucoadhesive polymers like Carbopol 934P, chitosan, carboxymethylcellulose sodium, sodium alginate, methyl cellulose, hydroxypropyl methylcellulose and hydroxypropyl cellulose. Effervescent was incorporated into formulations to enhance swellabilty of mucoadhesive tablet. For various drug-free form...

buccoadhesive drug delivery systems have distinct advantages in comparison with oral administration. plant exudates like gum or mucilage are being studied for their use as pharmaceutical adjuvant. the aim of this study is to evaluate the properties of the plantago major seed mucilage as a mucoadhesive agent and propranolol hydrochloride is chosen as a model drug. mucoadhesive tablets of propran...

Floating drug delivery systems (FDDS) are utilized to target discharge in the stomach or upper parts of intestine. Famotidine has been most extensively used for management peptic ulcer various decades. The current study concerns development and evaluation floating tablets famotidine which, after oral administration, planned extend gastric residence time, enhance bioavailability aim ulcer. A FDD...

Buccoadhesive tablets of Metclopramide Hydrochloride were fabricated with objective of avoiding extensive first pass metabolism and to prolong its duration of action with reduction in dosing frequency. The mucoadhesive polymers used in the formulations were Carbopol 934P, Chitosan, HPMC K4M and HPMC K15M. Tablets were prepared by direct compression method using polymer in different ratios. The ...
