摘要:The present invention describes novel nitrosated and/or nitrosylated phosphodiesterase inhibitors, and novel compositions containing at least one nitrosated and/or nitrosylated phosphodiesterase inhibitor, and, optionally, one or more compounds that donate, transfer or release nitric oxide, elevate endogenous levels of endothelium-derived relaxing factor, stimulate endogenous synthesis of nitric oxide or is a substrate for nitric oxide synthase and/or one or more vasoactive agents. The present invention also provides novel compositions containing at least one phosphodiesterase inhibitor, and one or more compounds that donate, transfer or release nitric oxide, elevate endogenous levels of endothelium-derived relaxing factor, stimulate endogenous synthesis of nitric oxide or is a substrate for nitric oxide synthase and/or one or more vasoactive agents. The present invention also provides methods for treating or preventing sexual dysfunctions in males and females, for enhancing sexual responses in males and females, and for treating or preventing diseases induced by the increased metabolism of cyclic guanosine 3′,5′-monophosphate (cGMP), such as hypertension, pulmonary hypertension, congestive heart failure, renal failure, myocardial infraction, stable, unstable and variant (Prinzmetal) angina, atherosclerosis, cardiac edema, renal insufficiency, nephrotic edema, hepatic edema, stroke, asthma, bronchitis, chronic obstructive pulmonary disease (COPD), cystic fibrosis, dementia, immunodeficiency, premature labor, dysmenorrhoea, benign prostatic hyperplasis (BPH), bladder outlet obstruction, incontinence, conditions of reduced blood vessel patency, e.g., postpercutaneous transluminal coronary angioplasty (post-PTCA), peripheral vascular disease, allergic rhinitis, glucoma, and diseases characterized by disorders of gut motility, e.g., irritable bowel syndrome (IBS).

标 题 :Nitrosated and nitrosylated phosphodiesterase inhibitor compounds, compositions and their uses
发明人：GARVEY DAVID S; DE TEJADA INIGO SAENZ
摘要:The invention provides methods for treating female sexual dysfunctions by administering to a female individual a therapeutically effective amount of at least one compound that donates, transfers or release nitrogen monoxide, that induces the production of endogenous endothelium-derived relaxing factor, that stimulates endogenous synthesis of nitrogen monoxide, or that is a substrate for nitric oxide synthase. The methods may further comprise administering a therapeutically effective amount of a phosphodiesterase inhibitor and/or a nitrosated and/or nitrosylated phosphodiesterase inhibitor.
