3-substituted-5,5-diphenylhydantoin derivatives in which the 5,5-diphenylhydantoin moiety is attached at C.sub.3 by a loweralkylene bridge to a 4-phenyl-1-piperidyl, 4-hydroxy-4-phenyl-1-piperidyl, 4-phenyl-1,2,3,6-tetrahydropyridyl, 4-phenyl-1-piperazinyl, or loweralkylamino group are useful in the treatment of cardiac arrhythmias in mammals. One or both of the 5,5-diphenyl substituents optionally can be substituted in the ortho-, meta-, or para-positions with halogeno, lowerakyl, loweralkoxy, amino or nitro groups.
3-取代-5,5-二苯基海达嗪衍生物,其中5,5-二苯基海达嗪基团通过较低的烷基桥连接到C.sub.3处,形成4-苯基-1-哌啶基、4-羟基-4-苯基-1-哌啶基、4-苯基-1,2,3,6-四氢吡啶基、4-苯基-1-哌嗪基或较低的烷基氨基团,在哺乳动物心律失常的治疗中是有用的。其中一个或两个5,5-二苯基取代基可以选择性地在邻位、间位或对位与卤素、较低烷基、较低烷氧基、氨基或硝基团进行取代。
