Abstract:
Objective:To explore therapeutic effect of bisoprolol with CYP2D6 and CYP3A4 gene targeting therapy for hypertension .Methods :A total of 100 cases with essential hypertension (EH) were selected ,among them 20 ca-ses were randomly chosen to receive routine medication (bisoprolol 5 mg/d ,routine treatment group ) ,the other 80 patients were equally divided into group A (CYP2D6*10) and group B (CYP3A4*1G) .According to detection results of CYP2D6*10 and CYP3A4*1G gene polymorphism ,they were dived into group ACC (n=13) ,group ACT (n=14) ,group ATT (n=10) ,group BCC (n=21) ,group BCT (n=17) and group BTT (n=0) .Bisoprolol dosage was adjusted according to genotypes :group ACC and group BCC received 10 mg/d ,group ACT and group BCT received 5 mg/d ,group ATT and group BTT received 2.5 mg/d .Blood drug concentration ,blood pressure and heart rate were compared among above groups after two weeks .Relationship between plasma concentration of bisoprolol and gene polymorphism of drug metabolism enzyme was evaluated .Results:Comparison between related groups with same bi-soprolol dosage :there were no significant difference in blood drug concentration ,heart rate and blood pressure be-tween ACT and routine treatment group , P>0.05 all;compared with routine treatment group ,there was significant rise in blood drug concentration [ (33.5 ± 19.1) ng/ml vs .(50.13 ± 23.21) ng/ml] ,significant reduction in heart rate [ (71.4 ± 5.16) times/min vs .(66.5 ± 6.04) times/min] and blood pressure [ (127.22 ± 10.44/82.4 ± 7.27) mmHg vs .(119.48 ± 11.97/71.2 ± 10.30) mmHg] in BCT group , P<0.05 all .Conclusion:Because gene possesses polymorphism ,therapeutic effect of bisoprolol treating hypertension is differing ;the gene targeting therapy may significantly improve therapeutic effect for hypertension .
