the aim of this study was to develop an extended-release tablet formulation using a new in situ cross-linking method. the effects of polyvalent cations on theophylline release from tablets made with the polyanionic polymers sodium alginate and sodium carboxymethylcellulose, were investigated. different miliequivalents of the di and tri-valent cation, ca2+ and al3+, were added to tablet formulat...
Floating dosage forms of acetylsalicylic acid, used for its antithrombotic effect, were developed to prolong gastric residence time and increase bioavailability. In the two-layer tablet formulation, hydroxypropyl methylcellulose (HPMC) of high viscosity and an effervescent mixture of citric acid and sodium bicarbonate formed the floating layer. The release layer contained the drug, direct table...
Frequent dosing of the potent anti-androgen, flutamide, is necessary to reach a therapeutic level for the treatment of prostatic carcinoma. Sustained delivery of the drug could reduce the adverse effects such as gastrointestinal disorders and improve patient compliance. In the present study sustained-release matrix tablets of flutamide were prepared by direct compression method using different ...
Incorporation of bisphosphonates in the lipid reduces gastric irritation. Only gastric retention with sustained release allows the drug to reach the duodenum and jejunum and improves the availability of bisphosphonates. Risedronate sodium and Gelucire 39/01 floating matrices were prepared using melt solidification. The sustained release floating matrices were evaluated for in vitro and in vivo ...

BACKGROUND Amoxicillin is a commonly used antibiotic which has a short half-life in human. The frequent administration of amoxicillin is often required to keep the plasma drug level in an effective range. The short dosing interval of amoxicillin could also cause some side effects and drug resistance, and impair its therapeutic efficacy and patients' compliance. Therefore, a three-pulse release ...
This study was performed to design bilayer floating tablets of simvastatin and lovastatin to give sustained release of simvastatin and immediate release of lovastatin. Bilayer floating tablets comprised of two layers i.e, immediate and sustained release layers. Bilayer floating tablets of simvastatin and lovastatin was formulated by using HPMCK 100M and super disintegrants like sodium alginate,...
Lamivudine, a BCS Class I synthetic nucleoside analogue, has a a short biological half-life of 5–7 and is mainly absorbed in the upper gastrointestinal tract. The purpose of the study is to develop a controlled release floating tablets of lamivudine employing HPMC K4M and sodium alginate. The floating tablets of lamivudine were prepared employing HPMC K4M and sodium alginate as matrix formers a...
