Abstract:
The invention particularly discloses a process for preparing aryl alkyl carboxylic acid salts by preparing aqueous alkali solution, adding aryl alkyl carboxylic acid to said alkali solution at a temperature ranging from 4° to 121° C for obtaining a clear solution, preferably by heating and/or stirring and concentrating and cooling to obtain aryl alkyl carboxylic acid salt The invention therefore discloses solid oral dosage forms and compositions of aryl alkyl carboxylic acid salts which are free of organic solvent/so. The solid oral dose compositions of aryl alkyl carboxylic acid salts of the invention arc prepared in situ from aryl alkyl carboxylic acids and bases to obtain aryl acid alkyl carboxylic acid sails in crystalline/powder form with or without the use of pharmaceutical excipients.
Abstract:
Therapeutic conjugates containing a statin or a modified statin (collectively 'statin') linked to a therapeutic agent (also referred to as a drug herein) are targeted to the liver by the statin or modified statin and thereby deliver the therapeutic agent to liver cells.
Abstract:
Novel esters of nonsteroidal anti-inflammatory drugs with oligomers of 3-hydroxybutyric acid of the invention possess the general formula 1, where n from 2 to 35, and R is a radical of a non-steroidal anti-inflammatory drug selected from the group consisting of ibuprofen, ketoprofen, fenoprofen, naproxen, diclofenac, indomethacine, sulindac, tolmetin or salicylic acid. The method of preparation of compounds of the formula 1 consists in converting nonsteroidal anti-inflammatory drugs into a monosodium or monopotassium salts in the presence of a strongly polar solvent, preferably dimethyl sulfoxide (DMSO) or dimethylformamide (DMF), and in subjecting the obtained salts to the reaction with β-butyrolactone to open the lactone ring and to polymerize the lactone. The esters of the invention contain a nonsteroidal anti-inflammatory drugs bonded by means of an ester bond with oligomers of 3-hydroxybutyric acid including 2-35 mers as constituting biocompatible polymer carriers.
Abstract:
The invention features compounds that inhibit COX-2 and/or FAAH. The COX-2 inhibitors are selective COX-2 inhibitors in that they are selective for COX-2 compared to COX-1. Certain of the FAAH inhibitors are selective for FAAH relative to COX-2. Certain of the COX-2 inhibitors, in addition for being selective for COX-2 relative to COX-1, are selective for COX-2 relative to FAAH.
Abstract:
This invention relates to the use of potent potassium channel blockers or a formulation thereof in the treatment of glaucoma and other conditions which leads to elevated intraoccular pressure in the eye of a patient. This invention also relates to the use of such compounds to provide a neuroprotective effect to the eye of mammalian species, particularly humans.
