Abstract
Embodiments of stable topical compositions for administering fenoldopam (compound (I) or a pharmaceutically acceptable salt or solvate thereof are disclosed for immediate or continued slow release administration, over prolonged periods of time with safe minimal systemic exposure of fenoldopam (reducing the risk for lowering blood pressure). The compositions include those compositions that increase the stability and skin absorption of the drug, particularly anhydrous semi-solid compositions and creams. This is accomplished by incorporating fenoldopam in soluble or dispersed form into semi-solid compositions like ointments or anhydrous gels that are not irritative. Embodiments of methods for using the topical compositions in the treatment of dermatological disorders including psoriasis, alopecia atopic dermatitis and vitiligo are disclosed.

The level of toxic impurities in the malathion, e.g., isomalathion, O,O,S-trimethyl phosphorodithioate (MeOOSPS), O,O,S-trimethyl phosphorothioate (MeOOSPO), O,S,S-trimethyl phosphorodithioate (MeOSSPO), malaoxon, isomalathion, diethyl fumarate, methyl malathion, dimethyl malathion, O,O-methyl,ethyl-S-(1,2-dicarboethoxy)ethyl-phosphorodithioate are lower than that of any other commercial preparation of malathion that may be used for pharmaceutical purposes.
This invention is directed to a process for the preparation of pure ropinirole hydrochloride with purity of equal to or greater than 99.8% and less than 0.1% isatine impurity. In the process of the present invention, the isatine is removed during the reaction steps and no further cleaning steps are required.
The present invention provides a pharmaceutical composition comprising a combination of an anti-androgen agent and an antibiotic/anti-inflammatory agent or pharmaceutically acceptable salts thereof, useful for treating a subject with a dermatological disorder. The combination of this invention preferably provides a synergistic effect in treating a subject with a dermatological disorder, specifically a subject with acne. In a preferred embodiment, the present invention provides a pharmaceutical composition comprising combination of spironolactone and doxycycline or pharmaceutically acceptable salts or hydrates thereof.

The present invention provides for a storage stable pharmaceutical liquid solution for oral administration having a pharmaceutically effective amount of an antihistamine and having a purity equal to or greater than about 99% by weight-based HPLC assay, residual solvents of less than about 0.5%, and a total impurity of less than about 0.2%. The storage stable solution preferably contains cetirizine. The present invention further provides a process of preparing the storage stable pharmaceutical liquid solution as well as a method of treating a mammal with a therapeutically effective amount of cetirizine in the stable pharmaceutical liquid solution.

The present invention provides a process of preparing a crystalline azithromycin monohydrate. The process involves dissolving azithromycin in a solution containing ethanol, adding the dissolved azithromycin into water to precipitate the crystals, isolating and drying the precipitate to a water content of about 5% (w/w) to about 7% (w/w). The resulting azithromycin monohydrate is stable, exhibiting less than 2% degradation, and non-hydroscopic.
