The antitussive activity of levodropropizine (S(-)3-(4-phenyl-piperazine-1-yl)-propane-1,2-diol, DF 526, CAS 99291-25-5) was evaluated after oral administration to the conscious dog. Levodropropizine had a good antitussive activity, comparable with, but having a longer duration of action than dropropizine, the racemate from which it is derived. The antitussive activity of levodropropizine in the dog was approximately 1/20 of that of codeine phosphate.
在对清醒犬口服给药后,评估了左羟丙哌嗪(S(-)-3-(4-苯基-哌嗪-1-基)-丙烷-1,2-二醇,DF 526,CAS 99291-25-5)的镇咳活性。左羟丙哌嗪具有良好的镇咳活性,与它所衍生的消旋体右羟丙哌嗪相当,但作用持续时间更长。左羟丙哌嗪在犬体内的镇咳活性约为磷酸可待因的1/20。
