摘要:
Sustained release pharmaceutical composition comprising at least one poorly soluble active agent(s), at least one solubilizer, a release rate controlling polymer system consisting of an acid-soluble polymer and a pH-dependent polymer, and optionally other pharmaceutically acceptable excipients. The present invention also describes a process for preparation of such compositions and method of using such compositions. The sustained release compositions are useful in providing therapeutically effective levels of active agent(s) for extended periods of time.
摘要:
Pharmaceutical modified release dosage form comprising at least one cyclooxygenase enzyme inhibitor or its pharmaceutically acceptable salts, esters, prodrugs, solvates, hydrates, or derivatives thereof as active agent, with a pharmaceutically acceptable carrier for controlling the release of the cyclooxygenase enzyme inhibitor is provided. The dosage form preferably provides a release of not more than about 60% of the cyclooxygenase enzyme inhibitor in 1 hour and not less than about 75% of the cyclooxygenase enzyme inhibitor after 12 hours when tested in accordance with the dissolution method (I) described herein employing Distilled water with 2.0% Sodium lauryl sulphate as the dissolution medium or in accordance with the dissolution method (II) described herein employing pH 7.0 Phosphate buffer with 2.0% Sodium lauryl sulphate as the dissolution medium or in accordance with the dissolution method (III) described herein employing 0.001 N Hydrochloric acid with 1.0% Sodium lauryl sulphate as dissolution medium. Further, the pharmaceutical composition of the present invention when tested in a group of healthy humans preferably achieves a mean peak plasma concentration (Cmax) after at least about 1 hour of administration of the dosage form. The present invention also provides process of preparing such dosage form compositions and prophylactic and/or therapeutic methods of using such dosage form.
摘要:
Low dose pharmaceutical dosage form comprising nimesulide or its pharmaceutically acceptable salts, esters, solvates or hydrates thereof, along with one or more pharmaceutically acceptable excipient(s) are provided. The present invention also provides process of preparing such dosage forms and therapeutic methods of using such dosage forms. The low dose compositions 10 are designed to exhibit such bioavailability, which is effective in the treatment of NSAID indicated disorders particularly, which require long-term treatment regimens such as arthritis. Such compositions reduce the cost of therapy in diseases, which require long-term therapies, are easy to manufacture, and also result in the reduction of dose related side effects associated with nimesulide therapy.
摘要:
Novel injectable compositions are provided comprising an active agent which is tamsulosin or letrozole or its pharmaceutically acceptable salts, derivatives, isomers, polymorphs, solvates, hydrates, analogues, enantiomers, tautomeric forms or mixtures thereof and one or more pharmaceutically acceptable excipient(s) wherein the compositions are preferably formulated as biodegradable microparticles or nanoparticles which can optionally be reconstituted with an aqueous, hydro-alcoholic or oily liquid vehicle prior to administration. The novel injectable compositions of the present invention preferably form a depot upon administration in vivo and are in the form of an in situ gelling composition or an implant composition which provides a prolonged release of tamsulosin or letrozole for extended periods of time. Also described are process for preparation of such novel compositions and method of using them.
摘要:
Novel injectable depot compositions are provided comprising at least one active agent(s) optionally with one or more pharmaceutically acceptable excipient(s) in the form of a multi-component system preferably comprising at least two components which when administered to a subject in need thereof forms an in situ gel depot or implant at the site of injection upon contact with body fluids. Also described are process for preparation of such compositions and method of using such compositions.
摘要:
The invention relates to novel compositions comprising of an extract of the plant Euphorbia prostrata, particularly with pharmaceutically acceptable carrier(s)/base(s), optionally with additional therapeutic agent(s) useful for the treatment of anorectal disease and colonic diseases such as hemorrhoids, fissures, cracks, fistulas, abscesses, inflammatory bowel disease, and the like. The novel compositions possess properties to control inflammation, prevent capillary bleeding and fragility in mammalians, particularly human beings. Process for the preparation of such novel compositions comprising an extract of the plant Euphorbia prostrata and pharmaceutically acceptable carrier(s)/base(s) useful for the treatment of anorectal disease including hemorrhoids, and colonic diseases are also provided. The composition comprise of flavonoidal and phenolic constituents extracted from the plant Euphorbia prostrata that possess anti-inflammatory, analgesic, haemostatic and wound-healing properties.
摘要:
Novel compositions comprising a combination of at least one higher primary aliphatic alcohol preferably selected from those having 18 to 40 carbon atoms or mixtures thereof, at least one source of 5-hydroxytryptophan (5-HTP) optionally additionally comprising a source of caffeine and/or catechin-polyphenol and/or epigallocatechin gallate as active agents, either alone or in combination with other active agent(s), optionally with one or more excipient(s) are provided. Particularly, the invention relates to compositions and process for preparation of such compositions and method of use thereof for the management of obesity and associated disorders.
摘要:
Pharmaceutical sustained release composition comprising at least one active agent(s), or its tautomeric forms, analogues, isomers, polymorphs, solvates, or salts thereof; preferably an antiviral active agent is provided. Also provided is a process of preparation of such composition and method of using them. The sustained release compositions of the present invention are able to deliver the active agent in a desired manner for an extended period of time.
摘要:
Novel modified release pharmaceutical composition comprising at least one active agent(s); a polymer system in an amount less than about 80% w/w of the composition comprising at least two swellable pH independent polymers wherein at least one is hydrophilic; optionally other pharmaceutically acceptable excipients is provided. Process for preparation of such compositions and methods of using them is also provided. The compositions are formulated into suitable dosage forms that provide therapeutic concentrations of active agent for extended periods of time.
