Enantiomerically-pure dihydropyridines of formula I ##STR1## are effective vasodilators useful for treating coronary diseases. They have particularly advantageous properties with regard to extent and controllability of blood pressure lowering, a surprisingly small (and for repeated administration--vanishing) increase in heart rate, excellent bioavailability, high therapeutic index, lack of central side effects, lack of kinetic interactions with other substances, absence of tolerance development, well-balanced physical properties and high stability. A new process for preparing these compounds is also presented.
公式I表示的对映纯二氢吡啶是有效的血管扩张剂,可用于治疗冠心病。它们在降低血压的程度和可控性方面具有特别有利的性质,心率增加非常小(对于重复使用则消失),生物利用度优异,治疗指数高,没有中枢副作用,与其他物质没有动力学相互作用,不会产生耐受性,物理性质平衡,稳定性高。还提供了一种制备这些化合物的新工艺。
