To evaluate the effectiveness and safety of Ginkgo biloba extract (GBE50) in the treatment of dizziness caused by cerebral arteriosclerosis. This was a multi-center, double-blind, double-dummy, positive-controlled, parallel randomized controlled clinical trial with 1? allocation. We recruited 404 patients with dizziness caused by cerebral arteriosclerosis (blood stasis symptom pattern) in 10 hospitals in China. GBE50 group received GBE50 and Naoxinqing tablet (NXQ) of mimetic agent, control group received NXQ and GBE50 of mimetic agent. The main outcome was Traditional Chinese Medicine (TCM) symptom pattern score of blood stasis after 6 weeks. The secondary outcomes were changes in the dizziness handicap inventory (DHI) score, vertigo visual analogue scale (VAS) score, the university of California vertigo questionnaire (UCLA-DQ) score and single-item symptom score of TCM from baseline to 2, 4 and 6 weeks. Safety indicators included the incidence of adverse events, severe adverse events and laboratory examination including blood routine, liver function, renal function, and so forth. The total effective rate of TCM symptom pattern score in the GBE50 group after 6 weeks of treatment was higher than that in the control group, the difference in rate was statistically significant (92.67% vs 83.07%, P = 0.004). Compared with the control group, there was no difference in the incidence of adverse reactions (9.95% vs 14.85%, P = 0.136). The treatment of dizziness caused by cerebral arteriosclerosis with GBE50 is effective, safe and reliable.
