Current drugs for the treatment of visceral leishmaniasis are inadequate. No novel compound is in the pipeline. Since economic returns on developing a new drug for neglected disease, leishmaniasis is so low that therapeutic switching represents the only realistic strategy. It refers to "alternative drug use" discoveries which differ from the original intent of the drug. Amphotericin B, paromomycin, miltefosine and many other drugs are very successful examples of "new drugs from old". This article reviews the discovery, growth and current status of these drugs and concluded that the potential of this approach (therapeutic switching) may use in the development of new antileishmanials in future also.
目前用于治疗内脏利什曼病的药物并不理想。尚无新型化合物处于研发阶段。由于研发治疗被忽视疾病利什曼病新药的经济回报很低,因此治疗转换是唯一现实的策略。它指的是与药物原始意图不同的“替代药物使用”发现。两性霉素B、巴龙霉素、米替福新和许多其他药物都是“旧药新用”的非常成功的例子。本文回顾了这些药物的发现、发展和现状,并得出结论,这种方法(治疗转换)在未来开发新的抗利什曼病药物方面也可能具有潜力。
