this study was performed to design bilayer regioselective floating tablets of atenolol and lovastatin to give immediate release of lovastatin and sustained release of atenolol. bilayer floating tablets comprised two layers, i.e immediate release and controlled release layers. the immediate release layer comprised sodium starch glycollate as a super disintegrant and the sustained release layer c...

the present investigation deals with the development of controlled release tablets of salbutamol sulphate using graft copolymers (st-g-pmma and ast-g-pmma) of starch and acetylated starch. drug excipient compatibility was spectroscopically analyzed via ft-ir, which confirmed no interaction between drug and other excipients. formulations were evaluated for physical characteristics like hardness,...

Polysaccharide mucilage derived from the seeds of Ocimum basilicum L. (family Lamiaceae) was investigated for use in matrix formulations containing propranolol hydrochloride. Basil mucilage was extracted and several tablets were formulated. The effect of mucilage on drug release rate was evaluated in comparison with tablets containing two kinds of hydroxypropyl methylcellulose (HPMC K4M and HPM...

DESCRIPTION GLUCOPHAGE (metformin hydrochloride) Tablets and GLUCOPHAGE XR (metformin hydrochloride) Extended-Release Tablets are oral antihyperglycemic drugs used in the management of type 2 diabetes. Metformin hydrochloride (N,N-dimethylimidodicarbonimidic diamide hydrochloride) is not chemically or pharmacologically related to any other classes of oral antihyperglycemic agents. The structura...

This study aimed to produce a gastroretentive floating tablet of Metoprolol succinate and examine the effects release retardant on in vitro drug release. is β1 selective antagonist used as an Anti-hypertensive, Antiarrhythmic, Anti Angina. has 48% oral bioavailability due limited absorption from lower gastrointestinal tract. The tablets were designed increase stomach retention, prolong release,...

The influence of various polymers on the release rate of lithium carbonate from matrix-type tablets was investigated in an attempt to formulate a sustained release solid dosage form. For this purpose, tablets containing 450 mg of lithium carbonate along with various amounts of Carbopol 934P, 971P, 974P, Pemulen and Eudragit RLPO as retarding agents and inactive ingredients (e.g. PVP, Avicel or ...
