The present invention provides a method for a more efficacious treatment of a vascular condition through the administration of a therapeutically effective amount of a combination of an anti-pressor agent, an endothelin antagonist, and a sex hormone for repetitive cycles of on/off-treatment. In one embodiment, the invention provides a method for the prevention of tolerance induced by an anti-pressor agent via the inclusion of an endothelin antagonist in a combination therapy approach to remodel vascular structure and treat vascular conditions associated with a male or female sexual dysfunction, atherosclerosis, renal failure, hypertension, congestive heart failure, diabetic nephropathy, and diabetic neuropathy. The anti-pressor agent comprises one or more compounds such as prostaglandin-E

-adrenergic receptor antagonist, a &bgr;-adrenergic receptor antagonist, a calcium channel blocker, an activator of guanylyl cyclase or adenyl cyclase, a phosphodiesterase inhibitor, and hydralazine. The endothelin antagonist comprises one or more compounds such as a peptidal endothelin antagonist, a non-peptidal endothelin antagonist, and an inhibitor of endothelin converting enzyme. Such a combination therapy approach enhances the efficacy of the anti-pressor agent and enables an increase in the frequency and duration of anti-pressor administrations for the long term treatment of vascular conditions.
本发明提供了一种更有效地治疗血管疾病的方法,通过给予治疗有效量的抗压剂、内皮素拮抗剂和性激素的组合,进行重复周期的开/关治疗。在一个实施方案中,本发明提供了一种通过在联合疗法中加入内皮素拮抗剂来预防由抗压迫剂诱发的耐受性的方法,以重塑血管结构并治疗与男性或女性性功能障碍、动脉粥样硬化、肾功能衰竭、高血压、充血性心力衰竭、糖尿病肾病和糖尿病神经病变相关的血管疾病。抗压剂包括一种或多种化合物,如前列腺素-E
