塞利洛尔(celiprolol)为新一代β-肾上腺素受体阻滞剂,对β_1-受体有特异性拮抗作用,对β_2-受体则有较弱的特异性激动作用,因而临床应用可产生有益的效应。塞利洛尔拮抗异丙肾上腺素对心肌的收缩效应,其效能与普萘洛尔或阿替洛尔相仿;但拮抗异丙肾上腺素的降压效应,塞利洛尔的效能只及普萘洛尔的1/200。在旋光异构体间,塞利洛尔的左旋体作用较强。自发性高血压大鼠一次口服塞利洛尔60mg/kg,平均
Celiprolol is a new generation of β-adrenoceptor antagonist, which has specific antagonism of β 1 -receptor and weak specific agonism of β 2 -receptors. Therefore, the clinical application of celiprolol Have a beneficial effect. Celipron antagonizes the contractile effect of isoproterenol on myocardium and its efficacy is similar to that of propranolol or atenolol; however, the antihypertensive effect of isoprenaline is antagonized by ciproferzine, Lol’s 1/200. Among the optical isomers, the effect of celiprolol is stronger. Spontaneous hypertensive rats were given oral celiprolol 60mg / kg, on average
