Disclosed is a pharmaceutical composition for extended release of an erythromycin derivative in the gastrointestinal environment. The composition comprises an erythromycin derivative and a pharmaceutically acceptable polymer so that, when ingested orally, the composition induces statistically significantly lower C_max in the plasma than an immediate release composition of the erythromycin derivative while maintaining bioavailability and minimum concentration substantially equivalent to that of the immediate release composition of the erythromycin derivative upon multiple dosing. The compositions of the invention have an improved taste profile and reduced gastrointestinal side effects as compared to those for the immediate release composition.

Extended release formulations of S-methyladenosylmethionine (SAMe) are provided, as are methods of treating various disorders using extended release SAMe formulations. The extended release formulations may be used to treat a variety of disorders, including liver disorders, psychiatric disorders and joint disorders. Thus, extended release SAMe formulations may be used to treat alcoholic liver disease, fatty liver disease, hepatitis, generalized anxiety disorder, obsessive compulsive disorder, post traumatic stress disorder, panic disorder, and depressive disorders such as depression (e.g. major clinical depression) and dysthymia.

Tranexamic acid formulated in an oral dosage form with at least one agent that decreases tranexamic acid release in the stomach. Such formulations minimize nausea, vomiting, and other adverse gastric effects that may accompany tranexamic acid therapy, for example, to treat heavy menstrual bleeding. One embodiment is an extended release formulation with waxes, polymers, etc. that prevent a bolus release of tranexamic acid in the stomach. An alternative embodiment is a delayed release formulation with polymers that prevent release of tranexamic acid in the acid environment of the stomach and delay its release until the formulation reaches the less acid environment of the intestines. Such formulations enhance patient compliance with therapy because adverse effects of tranexamic acid therapy are reduced.

Modified or extended release formulations containing mesalamine compounds and associated methods are disclosed and described. In some aspects, such formulations may be substantially bioequivalent to known FDA approved mesalamine formulations such as PENTASA®.

The present invention relates to extended release pharmaceutical compositions of Levetiracetam and processes for preparing the same. The extended release tablet of Levetiracetam is with a core comprising of Levetiracetam and water dispersible rate controlling polymer, and the tablet core is optionally functional coated comprising a combination of water non-dispersible and/or water dispersible polymer. It provides extended therapeutically effective plasma levels over a twenty four hour period with diminished incidences of neuropsychiatric adverse events by eliminating the troughs and peaks of drug concentration in a patient's blood plasma. The composition also exhibits no food effect.

An improved controlled release dosage form for once-daily administration of carvedilol is described. The controlled release dosage form comprises a therapeutically effective amount of carvedilol and/or a pharmaceutically acceptable salt thereof; one or more hydrophilic polymers; one or more pharmaceutically acceptable excipients; and a polyoxyalkylene block copolymer, a solid dispersion of carvedilol and an extrusion material or a combination of a polyoxyalkylene block copolymer, a solid dispersion of carvedilol and an extrusion material.

The present invention relates to compositions and methods for treating sialic acid deficiencies comprising extended release formulations.

The present invention relates to an extended release pharmaceutical composition comprising valproic acid, a pharmaceutically acceptable salt, ester, or amide thereof or divalproex sodium.

An extended release pharmaceutical compressed composition and dosage form comprising poorly water soluble macrolide antibiotic, surfactant and non-lipophilic, non-polymeric excipient is disclosed. The composition releases the macrolide antibiotic over an extended period of time, generally at least over 12 hours, even in the absence of a release rate-retarding polymer, release rate-retarding coating or release rate-retarding lipophilic excipient. The composition is suitable for once daily or twice daily oral administration for the treatment of many different types of bacterial infections. One embodiment of the compressed composition includes a drug-containing granular composition and a binding composition, wherein the two are mixed together and then compressed into a tablet or pill. The surfactant is in admixture with or coated onto the macrolide antibiotic, and it can be included in the granular composition and/or the binding composition. The non-polymeric, non-lipophilic excipient is included in the granular composition and/or the binding composition.

The present invention is directed to pharmaceutical capsules comprising extended release formulations of dipyridamole, processes for preparing such dipyridamole extended release formulations and their use in the treatment of stroke.

Pharmaceutical compositions comprising an extended release formulation of active compounds effective in the treatment of various pathological conditions are provided. More particularly, the invention provides methods of making and using extended release formulations comprising active compounds that present formulation challenges such as short biological half-life, instability, highly water soluble and/or high dose requirements. Specifically, orally administrable extended release pellet and tablet formulations of isovaleramide are preferred.

The present disclosure provides a once-daily water-soluble pharmaceutically active formulation for oral administration. In certain embodiments, the composition comprises a watersoluble pharmaceutically active organic compound incorporated into a small particulate, each particulate having a core of the water-soluble pharmaceutically active organic compound or an acceptable salt thereof in reversible association with a pharmaceutically acceptable drug-binding polymer. The core of the composition being surrounded by an insoluble water permeable membrane that is capable of delaying the dissolution of the pharmaceutically active compound therewithin and providing for extended release of the pharmaceutically active compound. In some embodiments, the formulation of the invention are designed to extend release of the pharmaceutically active organic compound for about 3 hours to about 8 hours, thereby enabling preparation of an extended release formulation for any pharmaceutically active compound with a half-life of from about 16 hours to about 21 hours.

The invention provides oral formulations for the treatment of cold and allergy symptoms. Each formulation combines an antihistamine, an antitussive, and/or a decongestant into one extended release composition. The invention further provides for methods of making and using such formulations, as well as for methods for preventing abuse or extraction of a single drug present in an oral extended release composition comprising two or more of an antihistamine, antitussive, and/or decongestant.

A pharmaceutical composition for controlled drug delivery comprising a beta-lactam antibiotic or its pharmaceutically acceptable hydrates, salts or esters, and one or more carbomers. The above beta-lactam antibiotics formulation avoids the limitations of known beta-lactam controlled release form which are found to be either complex and/or cost-extensive to obtain requiring multiphase and/or selective coatings or fail to achieve the desired controlled release for once daily dosage form. Importantly, in the beta-lactam antibiotic form of the above the rate-controlling polymer wherein the C_max of the formulation is substantially the same as that of a single dose of the immediate release formulation. Also advantageously the formulation achieves a rate controlling polymer wherein the T>MIC for the formulation is more than 17 hours when the MIC is 0.25 mcg/ml and more than 10 hours when the MIC is 2 mcg/ml. The above beta-lactam antibiotic form is thus directed to serve as the much desired simple and cost-effective controlled release form suitable for once daily administration.
