Paliperidone is a well known dopamine antagonist of the atypical antipsychotic class. In the present study Paliperidone was formulated as ER release tablets using natural and synthetic polymers separately or in combination. The aim of ER release formulation is to reduce the frequency of dosing. Tablets are prepared by direct compression method. The optimized formulations contain Paliperidone as...
Atenolol, an antihypertensive drug, has poor bioavailability (40-50%) and has has low elimination half life(6 hr). Atenolol is mainly absorbed in the stomach. The floating tablets of atenolol were prepared to increase the gastric retention, extend the drug release and to improve the bioavailability of the drug. The floating tablets were formulated using HPMC 100 cps, sodium alginate, carbopol 9...
In this work, starch acetate and propanoate derivatives with moderate degree of substitution were synthesized and characterized for employment as matrix formers for sustained release from tablets. Matrix tablets were prepared from cospray-dried and simple physical mixtures of starch/starch derivatives and theophylline as a model drug. The release was rapid for matrix tablets prepared from simpl...
an investigation into the effect of carbopols on the release of propranolol hcl from tablet matrices
in this study, attempts were made to evaluate the effect of various acrylic acid based carbopols on the release profile of a beta-adrenoreceptor blocking drug, propranolol hcl, from matrix-type tablets invitro. for this purpose, tablets containing 160 mg of propranolol hcl along with various amounts of carbopols 934 (c934), 971 (c971), 974 (c974) and pemulen (pem) were prepared using the wet gr...
The aim of this study is to prepare novel sorbitol based extended release tablets by melt dispersion method using carbamazepine as a model drug. Carbamazepine was melted along with sugar alcohol to get melt dispersion granules (MGDs) and was characterized by differential scanning calorimetry (DSC), powder X-ray diffractometry (XRD) and solubility study. The physical and chemical parameters...
Trimetazidine dihydrochloride, a cellular antiischemic agent indicated in the management and prophylaxis of angina pectoris is given as 20 mg thrice daily in the conventional dosage regimen. The purpose of the present study was to formulate and evaluate twice a day extended release tablets containing 30 mg trimetazidine dihydrochloride. The method developed to formulate these extended release t...
