Hydroxy propyl methyl cellulose (HPMC) is generally combined with hydrophobic polymers in fabricating oral controlled solid dosage forms. This study evaluated the utility of diverse grades of HPMC in developing a controlled release formulation for a hydrophilic drug, enalapril maleate. Controlled release uncoated tablets were prepared by direct compression technique. Two grades of HPMC (K100 an...

Objective: The study aimed to develop fast-dissolving films (FDFs) of the immunosuppressant drug tacrolimus monohydrate for sublingual administration, employing central composite design (CCD), improve its bioavailability. Methods: Tacrolimus: β-cyclodextrin inclusion complexes prepared earlier were formulated into FDFs. CCD was used developing optimal film formulation with desired characteristi...

An attempt was made to formulate Buccal patches of Isoxsuprine hydrochloride, a potent and long acting vasodilator and uterine suppressant , by using Hydroxyl propyl methyl cellulose(HPMC), Polyvinyl pyrolidone K-30 (PVP K-30) and Hydroxyl ethyl cellulose (HEC). Twelve batches of buccal patches were prepared by solvent casting technique in which the best formulation was found out. The polymers ...

Investigation on natural sources from plants, animals, and microorganisms that produce gums mucilages goes increasing day by to check their pharmaceutical applications. Different have been studied for effects but the use of date palm (Phoenix dactylifera L.) mucilage as a excipient is still under cover. The aim this study was therefore evaluate compare flow property binding ability crude, purif...

Hydralazine hydrochloride has a half-life of 2 to 4 hours with an oral bioavailability of 26-50%. Since hydralazine has a demethylating effect on various suppressor genes, it can be used in various types of cancer to support chemotherapy. The purpose of this study was to optimize and evaluate floating tablets of hydralazine hydrochloride designed to prolong the gastric residence time and to pro...

In this study, an injectable bone substitute (IBS) consisting of citric acid, chitosan, and hydroxyl propyl methyl cellulose (HPMC) as the liquid phase and tetra calcium phosphate (TTCP), dicalcium phosphate dihydrate (DCPD) and calcium sulfate dehydrate (CSD, CaSO4 x 2H2O) powders as the solid phase, were fabricated. Two groups were classified based on the percent of citric acid in the liquid ...

The objective was to describe and recommend the most effective combination of Natural-Based Product (NBP) mucoadhesive for Recurrent Aphthous Stomatitis (RAS) treatment. This systematic review writing based on PRISMA guidelines. articles published in last 10 y were selected using PubMed Google Scholar database carried out during May 2021. keywords were: natural-based product, mucoadhesive, Stom...

The objective of this study was to develop controlled release matrix embedded formulations of celecoxib (CCX) as candidate drug using hydroxy propyl methyl cellulose (HPMC) and ethyl cellulose (EC), either alone or in combination, using optimization techniques like polynomial method and composite design. This would enable development of controlled release formulations with predictable and bette...

Hydrogels are materials largely used in the formulation of pharmaceuticals since, in principle, they could produce a release system of zero-order kinetics, which is of great therapeutic interest. In this paper, a model was proposed for the description of the main transport phenomena involved in the drug release process from hydrogel matrices (water diffusion, polymer swelling, drug diffusion an...

The aim of the present work was to develop a gastroretentive floating tablet of Atenolol and investigate the effects of both hydrophilic and hydrophobic retardant on in vitro release. Atenolol is an antihypertensive drug with an oral bioavailability of only 50% because of its poor absorption from lower gastrointestinal tract. The floating tablets of Atenolol were prepared to increase the gastri...
