Abstract

Novel modified release pharmaceutical compositions wherein the composition comprises at least one antibiotic(s) preferably amoxicillin or its pharmaceutically acceptable salts, esters, polymorphs, isomers, prodrugs, solvates, hydrates, or derivatives thereof either alone or in combination with other antibiotic(s) as active ingredient, with at least one release modifying agent(s) for controlling the release of the beta lactam antibiotic optionally with one or more other pharmaceutically acceptable excipient(s) is provided, wherein the dosage form provides a release of not more than about 60 % of the antibiotic in about 30 minutes and not less than about 70 % of the antibiotic after 8 hours when subjected to in vitro dissolution study or when tested in vivo. Further, the compositions of the present invention which when tested in a group of healthy humans provide a mean peak plasma concentration (Cmax) after at least about 0.5 hour of administration of the dosage form. The present invention also provides process of preparing such dosage form and methods of using such dosage form.

Description

technical field [0001] The present invention relates to novel modified release pharmaceutical compositions, wherein the composition comprises at least one antibiotic, preferably amoxicillin, or pharmaceutically acceptable salts, esters, polymorphs, isomers, prodrugs, solvates thereof , hydrates or derivatives thereof, alone or in combination with other antibiotics as active ingredients, and at least one release regulator for controlling the release of β-lactam antibiotics, and optionally one or more other pharmaceutically acceptable excipient. wherein the dosage form provides a release of up to about 60% of the antibiotic within about 30 minutes and at least about 70% of the antibiotic after 8 hours when subjected to an in vitro dissolution study or when subjected to an in vivo test. Additionally, the compositions of the present invention provide mean peak plasma concentrations (C max ). The invention also provides methods of making such dosage forms and methods of using su...
