METHODS: A total of 120 vertigo patients with posterior circulation ischemia were randomly divided into observation group and control group. 60 patients in the control group were treated with conventional western medicine. 60 patients in the observation group were treated with Qiangli Dingxuan Tablet on the basis of the control group. After 2 weeks of treatment, the improvement of vertigo(dizziness handicap inventory(DHI), dizziness handicap inventory(DHI)), the hemodynamic index(Basilar artery blood flow velocity(BA), left vertebroarterial artery(LVA), and the average blood flow velocity of right vertebroarterial artery(RVA)) and the changes in brain stem auditory evoked potential(BAEP) of two groups were observed. And statistical analysis was conducted for the clinical efficacy and adverse reactions during treatment of two groups. RESULTS: The total effective rate of the observation group was significantly higher than that of the control group(P < 0.05). The DHI and DARS scores of the two groups were significantly lower than those before treatment(P < 0.05), and the degree of reduction was more obvious in the observation group(P < 0.05). The levels of BA, LVA and RVA in the two groups were significantly higher than those before treatment(P < 0.05), and the levels of BA, LVA and RVA in the observation group were significantly higher than those in the control group(P < 0.05). The indexes of BAEP latency I, II, III and indexes of BAEP peak latency I-III, III-V, IV were obviously lower than those before treatment(P < 0.05). Besides, the decrease of BAEP index in the observation group was significantly lower than that in the control group(P < 0.05). No adverse reactions occurred during the treatment of the two groups. CONCLUSION: Qiangli Dingxuan Tablet is able to significantly improve the cerebral hemodynamics and brainstem auditory evoked potentials of patients with PCIV, and quickly relieve vertigo. It is safe and reliable and worthy of clinical application.展开更多
