标题:Thromboxane inhibitors, compositions and methods of use
发明人：TEJADA INIGO SAENZ DE
摘要:The present invention describes methods for treating or preventing sexual dysfunctions in males and females, and for enhancing sexual responses in males and females by administering a therapeutically effective amount of at least one thromboxane inhibitor, and, optionally, at least one compound that donates, transfers or releases nitric oxide, elevates endogenous levels of endothelium-derived relaxing factor, stimulates endogenous synthesis of nitric oxide or is a substrate for nitric oxide synthase, and/or at least one vasoactive agent. The male or female may preferably be diabetic. The present invention also provides novel compositions comprising at least one thromboxane inhibitor, and, at least one compound that donates, transfers or releases nitric oxide, elevates endogenous levels of endothelium-derived relaxing factor, stimulates endogenous synthesis of nitric oxide or is a substrate for nitric oxide synthase, and, optionally, at least one therapeutic agent, such as, vasoactive agents, nonsteroidal antiinflanmmatory compounds (NSAIDs), selective cyclooxygenase-2 (COX-2) inhibitors, anticoagulants, angiotensin converting enzymes (ACE) inhibitors, angiotensin II receptor antagonists, renin inhibitors, and mixtures thereof. The present invention also provides methods for treating or preventing ischemic heart disorders, myocardial infarction, angina pectoris, stroke, migraine, cerebral hemorrhage, cardiac fatalities, transient ischaemic attacks, complications following organ transplants, coronary artery bypasses, angioplasty, endarterectomy, atherosclerosis, pulmonary embolism, bronchial asthma, bronchitis, pneumonia, circulatory shock of various organs, nephritis, graft rejection, cancerous metastases, pregnancy-induced hypertension, preeclampsia, eclampsia, thrombotic and thromboembolic disorders, intrauterine growth, gastrointestinal disorders, renal diseases and disorders, disorders resulting from elevated uric acid levels and dysmenorrhea, and for inhibiting platelet aggregation or platelet adhesion or relaxing smooth muscles.

标题 :Attaining sexual wellness and health of the sexual vascular system with proanthocyanidins
发明人：ROHDEWALD PETER; FERRARI VICTOR
摘要:Sexual wellness or sexual fitness is enhanced over time by administrating on a daily basis a source of proanthocyanidins and a source of arginine. Both sources may be blended into a composition or taken separately from a kit. The source of arginine may be a salt or peptide of L-arginine and aspartic acid such as arginine aspartate. The proanthocyanidins stimulate an endothelial NO-synthase enzyme, which serves as a catalyst for synthesis of the nitric oxide from a substration that is the source of the arginine. A sufficient amount of the nitric oxide is released over time to enhance sexual wellness or sexual fitness. In case of low levels of androgenic hormones in both sexes, the combination may contain as a further ingredient a sex hormone or a sex hormone precursor or a sex hormone stimulant or a sex hormone bioavailability enhancer.

标题:Relieving symptoms of erectile dysfunction with proanthocyanidins

摘要:Use of proanthocyanidins as an active ingredient of a stimulator as a source of arginine and a source of nitric oxide in the treatment of erectile dysfunction. The active ingredient stimulates the endothelial NO-synthase enzyme, which acts as a catalyst for the synthesis of nitric oxide from its substrate L-arginine or its salts. The nitric oxide in turn activates theguanylyl cyclase, which leads to an increased development of cyclic guanosine monophosphate, which causes relaxation of smooth muscles. Blood vessel diameter may increase. The stimulator may also have Sildenafil or enzymes that inhibit an enzyme phosphodiesterase type5 from reducing an amount of the cyclic guanosine monophosphate. The substrate may be amino acid L-arginine, arginine salts or a dipeptide of arginine and aspartic acid.
