理想的利尿药应符合下列条件:能按间质水肿液中电解质的比例(Na~+∶K~+=35∶1和Na~+∶Cl~-=1.3∶1)来消除电解质;能消除特定部位的水肿;能很好控制尿的形成,而对电解质平衡及尿酸、葡萄糖和脂肪的代谢无不良作用。因为至今尚无如此理想的利尿药,故联合应用利尿药作为相互补充,老药的合用也会显示此种可能性,例如噻嗪类和氨苯蝶啶联合应用,其 The ideal diuretic should meet the following conditions: the electrolyte in the interstitial edema solution (Na ~ +: K ~ + = 35: 1 and Na ~ +: Cl ~ - = 1.3: 1) to eliminate the electrolyte; Edema at specific sites; good control of urinary formation without adverse effects on electrolyte balance and metabolism of uric acid, glucose and fat.
