Abstract:
A process for forming amorphous atorvastatin comprising the steps of dissolving atorvastatin in a non-hydroxylic solvent and removing the solvent by freeze-drying, as well as processes of dissolving atorvastatin in a hydroxylic solvent with a solubilizing agent or an alkalizing agent or an antioxidant and removing the solvent by freeze-drying to afford amorphous atorvastatin.
Abstract:
An enanthioselective process for preparing the compounds of formulas (I) and (II) from the prochiral ketone precursor of the alcohol of formula (I). The compounds of formulas (I) and (II) are thus obtained in substantially enantiomerically pure form by reducing the ketone with a borane reducing agent in the presence of a chiral oxazaborolidine catalyst.
Abstract:
The present invention is directed to certain pharmaceutically acceptable salts of the therapeutically potent selective serotonin reuptake inhibitor, sertraline: Formula (I), and pharmaceutical compositions thereof, wherein said salts are selected from the group consisting of the p-toluenesulfonic acid salt, the fumaric acid salt, the benzenesulfonic acid salt, the benzoic acid salt, the L-tartaric acid salt and the (-)-camphor-10-sulfonic acid salt.
Abstract:
A process for preparing an anhydrous benzoate salt in crystallineform having formula (I) and the corresponding benzoate monohydrate in crystalline form. The benzoate salts and pharmaceutical compositions thereof are selective kappa-receptor agonists, and are useful as analgesics, anasthetics, anti-inflammatory or neuroprotective agents, or in the treatment of arthritis, stroke or functional bowel disease.
Abstract:
This invention is directed to compounds of formula (I) or the stereoisomers, pharmaceutically acceptable salts and hydrates thereof. The compounds are Apo B/MTP inhibitors and are useful in the treatment of various disorders and conditions such as atherosclerosis, pancreatitis, obesity, hypercholesteremia, hypertriglyceridemia, hyperlipidemia, and diabetes. The compounds of this invention are also useful in combination with other pharmaceutical agents including cholesterol biosynthesis inhibitors and cholesterol absorption inhibitors, especially HMG-CoA reductase inhibitors and HMG-CoA synthase inhibitors; HMG-CoA reductase gene expression inhibitors; CETP inhibitors; bile acid sequestrants; fibrates; cholesterol absorption inhibitors; ACAT inhibitors, squalene synthetase inhibitors, ion-exchange resins, anti-oxidants and niacin. This invention is also directed to intermediates and processes useful in the preparation of compounds of formula (I).
Abstract:
The present invention is directed to a polymorph of the citrate salt of 4-(3,4-dichlorophenyl)-2-[2-(4-methylpiperazin-1-yl)-benzylidene]-thiomorpholin-3-one (I) and pharmaceutical compositions thereof.
Abstract:
The present invention is directed to the succinate salts of 5,7,13-triazatetracyclo[9.3.1.0 2,10 .0 4,8 ]-pentadeca-2(10),3,5,8-tetraene and pharmaceutical compositions thereof. The invention is also directed to a process for preparation of the salts.
