Metformin hydrochloride is recommended globally as first line therapy due to its favorable profile on morbidity and mortality associated with type-2 diabetes mellitus. However, limitations of multiple dosing and risk of triggering gastrointestinal symptoms make its dose optimization difficult. Extended-release metformin matrix tablets were prepared by direct compression of drug and different pH...
In this paper, different formulation types of microparticulate systems such as beads, microbeads, microspheres and microsponges using to special attention chitosan, alginate and eudragit RS 100 are reviewed. Chitosan and alginates are natural, anionic or cationic, biocompatible, biodegredable and non-toxic polymers. They have excellent potential for pharmaceutical and biopharmaceutical applicat...
Purpose: To prepare and evaluate colon specific drug delivery system of diclofenac sodium for highly localized delivery to the colon. Methods: The colon specific drug delivery system was prepared as matrix-type microspheres using Ethyl Cellulose (EC), Cellulose Acetate Phthalate (CAP), and Eudragit L 100-55 by the Solvent Evaporation Method. Microspheres were evaluated for physical properties l...
The aim of the present study was to develop a single unit, site-specific matrix tablets of aceclofenac allowing targeted drug release in the colon with a microbially degradable polymeric carrier, chondroitin suphate (CS) and to coat the optimized batches with a pH dependent polymeric. The tablets were prepared by wet granulation method using starch mucilage as a binding agent and HPMC K-100 as ...
The aim of this study was to evaluate the influence of Na-bicarbonate as an effervescent agent on the floating and sustained-release characteristics in 0.1 M HCl of tablets made of Eudragit E PO (EE) and/or Eudragit L-100-55 (EL) as matrix formers at different EE:EL weight ratios: 0:100, 25:75, 50:50, 75:25, and 100:0. The tablets were made by direct compression utilizing metronidazole as a mod...
The bioactive aqueous extract of Nigella sativa L. seed waste was formulated into soft gelatin capsules (Su1-Su6) in a dose of 200 mg/kg b. w. using different pharmaceutical excipients: soya lecithin/ span80/ sodium taurocholate, PEG 400, and Meglyol 810. The formulations were evaluated for their immunostimmulant and hepatoprotective activities using biochemical methods and for their release by...
PURPOSE Nanoprecipitation is the convenient and commonly used method for the preparation of polymeric nanoparticles around 170 nm but yield particles with broad distribution, which require filtration step to produce particles with narrow distribution. Hence, the primary aim of the present study was to implement few modifications to the conventional nanoprecipitation method to reduce the mean pa...
the aim of the present study was to develop exemestane loaded polymeric nanoparticles for improved oral bioavailability of exemestane. exemestane loaded nanoparticles were prepared by solvent displacement method with eudragit rl 100 and eudragit l 100 as polymers and pluronic® f-68 as surfactant. the influence of various formulation factors (drug: polymer ratio and concentration of surfactant) ...
