Cardiotonic phosphodiesterase inhibitors complexed with water soluble vitamins |
摘要 |
This invention is directed to a formulation of cardiotonic phosphodiesterase inhibitors with a water-soluble vitamin, comprising a lyophilization step performed on a solution of the complex in an aqueous/organic solvent system. The formulation results in a complex that has been found to have enhanced solubility (over the compound alone) in a parenterally or orally acceptable solvent, and the lyophilization process yields a product with superior stability permitting an extended shelf life.
