The objective of the study was to compare pharmacokinetic and pharmacodynamic parameters of gliclazide after administration of immediate (IR) and modified release (MR) tablets. The experiment included rats with both normoglyceamia and streptozocin (STZ)-induced hyperglyceamia. Several MR formulations were designed and in vitro drug release profile was assessed by a dissolution test. For the fur...

mucoadhesive drug delivery systems were developed to sustain drug delivery via various mucus membranes for either local or systemic delivery of poorly absorbed drugs such as peptides and proteins as well as drugs that are subjected to high first-pass metabolism. the present study was undertaken to use isolated calendula mucilage as a mucoadhesive agent and to formulate controlled release buccoa...

Purpose: To develop orally disintegrating tablets of ondansetron HCl using natural Superdisintegrants. Method: Tablets containing the drug were prepared by dry granulation method using different concentrations of superdisintegrants such as modified gum karaya, modified natural agar, crosscarmellose sodium and sodium starch glycollate. The formulations were evaluated for weight variation, hardne...

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 of m...

Bilayer tablets are novel drug delivery systems where combination of two drugs in a single unit having different release profiles can be delivered. improve patient compliance, prolong the drug(s) action and deliver incompatible formulation. have one layer active ingredient for immediate second delayed release, either as dose or an extended fashion. advancing helpful technologies to overcome dis...

The clinical application of sirolimus (SRL) as an immunosuppressive agent is largely hampered by its narrow therapeutic range. This study focused on developing SRL tablets with a sustained release profile for better safety. SRL was highly water insoluble and its solubility has been efficiently enhanced by preparing self-microemulsifying drug delivery system (SMEDDS). The SRL-SMEDDS was physical...

An endeavor has been made to create buccoadhesive bilayered tablets comprising of drug containing bioadhesive layer and drug free backing layer to release the drug for extended period of time with reduction in dosing recurrence. Tablets of Tizanidine hydrochloride were prepared by direct compression method using bioadhesive polymer tamarind seed gum with backing layer of ethyl cellulose. The ph...

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 ...

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...
