Clinical Observation of Felodipine Sustained-release Tablets(Ⅱ)in the Treatment of Elderly Essential Hy-pertension / 中国药房

ABSTRACT

OBJECTIVE:To observe clinical efficacy of Felodipine sustained-release tablets(Ⅱ)in the treatment of elderly es-sential hypertension and its improvement effect on arterial elasticity,left ventricular remodeling and the quality of life. METHODS:A total of 96 elderly patients with essential hypertension in our hospital during Aug. 2014-Dec. 2015 were divided into observation group (50 cases) and control group (46 cases) according to random number table. Observation group was given Felodipine sus-tained-release tablets(Ⅱ)5 mg orally,qd,with empty stomach in the morning;control group was given Irbesartan tablets 150 mg, qd,with empty stomach in the morning. Both groups received treatment for 12 weeks. Clinical efficacies of 2 groups were observed as well as 24 h ambulatory blood pressure (ABP),indexes of arlerial elasticity [carotid-radial pulse wave velocity (CR-PWV),carot-id-femoral pulse wave velocity (CF-PWV)], indexes of left ventricular remodeling [diastolic interventricular septum thickness (IVST),diastolic left ventricular posterior wall thickness(LPWT),left ventricular end diastolic diameter(LVIDd)] before and after treatment. The physiological function (PF),social function (SF),role-physical (RP),body pain (BP),mental health (MH),role-emotional(RE),vitality(VT)and general health(GH)score of SF-36 were observed in 2 groups before and after treatment. The occurrence of ADR was compared between 2 groups. RESULTS:There was no statistical significance in total response rate be-tween 2 groups (P>0.05). There was no statistical significance in 24 hABP,CR-PWV,CF-PWV,IVST,LPWT,LVIDd,SF-36 score between 2 groups before treatment(P>0.05). After treatment,the levels of 24 hSBP,24 hDBP and 24 hMAP in 2 groups were decreased significantly,and 24 hSBP and 24 hMAP of observation groups were significantly lower than those of control group,with statistical significance (P0.05). The levels of CR-PWV,CF-PWV, IVST and LPWT in observation group were decreased significantly,and the levels of CR-PWV and LPWT in control group were also decreased significantly. The levels of CR-PWV,CF-PWV,IVST,LPWT and LVIDd in observation group were significantly lower than control group,with statistical significance (P0.05). CONCLUSIONS:Felodipine sustained-release tablets(Ⅱ)exhibit significant effect and small blood pres-sure fluctuation in the treatment of elderly essential hypertension,and can improve the quality of life with good safety.
