Herein, new extended-release tablets containing felodipine were developed. For the orally administered formulations, optimization of preformulation and formulation parameters was performed to assess performance dosage form. Initially, morphological physical characterization two forms (microcrystalline macrocrystalline) using Fourier transform infrared spectroscopy, differential scanning calorim...

Purpose: To develop and optimize controlled-release (CR) oxybutynin chloride matrix tablets. Methods: Oxybutynin CR tablets were prepared by embedding drug-containing granules into a hydrogel matrix of hydroxypropyl methylcellulose (HPMC). A coating layer was then applied with a mixture of HPMC, ethylcellulose, shellac, and HPMC phthalate. The effect of several formulation variables on in vitro...

The objective of the study is to formulate bilayer tablets consisting of atorvastatin calcium (AT) as an immediate release layer and nicotinic acid (NA) as an extended release layer. The immediate release layer was prepared using super disintegrant croscarmellose sodium and extended release layer using hydroxypropylmethyl cellulose (HPMC K100M). Both the matrix and bilayer tablets were evaluate...

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...

Tablet is most popular among all dosage forms today because of its convenience, ease administration, greater flexibility in form design, production, and low cost non-invasive therapy. Formulation tablets requires API along with excipients. Excipients include lubricants, diluents, binders, glidants, disintegrants, sweetening agents, flavoring etc. Recent trends indicate that multi-particulate dr...

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...
