《Expert opinion on therapeutic patents》2013,23(11):1297-1306
Critical reassessment of established inotropic drugs such as the phosphodiesterase inhibitors and the digitalis glycosides has reaffirmed the need for novel cardiotonic agents that will not only beneficially affect the haemodynamic and functional impairment of patients with overt congestive heart failure, but also prevent its clinical manifestation and reduce the high mortality. None of the drugs examined in these directions - calcium sensitisers, β-receptor blockers, sodium channel modulators, digitalis derivatives - have been shown to achieve these goals. The research on endogenous digitalis did not, as was hoped, reveal a general strategy for improving the therapeutic index of cardiac glycosides. The proof that Na+/K+-transporting ATPase of cardiac muscle is the molecular point of attack (receptor) for the inotropic and toxic effects of digitalis-like acting C/D-cis and C/D-trans steroids revealed the cyclopentano-perhydrophenanthrene nucleus as their common pharmacophoric lead structure. This has opened a wide field for lead development in the direction of derivatives that favourably discriminate between the inotropy-linked α1-isoform and the toxicity-linked α3-isoform of Na+/K+-ATPase as the basis for the design of inotropic agents with high therapeutic margin. 相似文献

心房颤动是临床常见的心律失常之一,其发病率越来越高。自1909年人类认识心房颤动以来,心房颤动的治疗经历了仅着眼于转复心房颤动本身的Ⅰ类抗心律失常药物、直流电转复以及外科迷宫手术等单一治疗,发展到针对心房颤动的病理基础、离子通道、并发症预防等综合治疗。治疗方式、方法、途径与以往比较也发生了巨大变化。虽然近年来房颤的射频消融有了飞速发展,但药物治疗仍然是一线治疗,有时甚至是唯一可行的方法。 相似文献

White petrolatums of Japanese Pharmacopoeia grade and Sun white marketed as a cosmetic were characterized by measuring their physical properties and drug-releasing characteristics. White petrolatums of Japanese Pharmacopoeia grade available commercially in Japan were Perfecta, White 1S, Ultima, Snow, Snow V and Regent (Propeto). Penetrating stress, shear stress and spreading properties were measured as physical properties of the white petrolatums. The physical properties of white petrolatums varied, and Regent was the softest and the most spreadable ointment base. In vitro release test was performed using flow-through Franz diffusion cells. Fluorescein isothiocyanate and tetracycline hydrochloride were used as drug models. Their release characteristics varied among the tested white petrolatums, and Regent had the best release properties. Among the white petrolatums, with the exception of Regent, the release properties should depend on the distribution of drugs between white petrolatum and the receiver solution. Considerations of usability and characteristics of theprincipal agent are needed when choosing white petrolatums. 相似文献
