    Abstract:
    Four calcium channel blockers, i.e. nifedipine, verapamil, cinnarizine and tetrandrine are currently available and used widely in treating cardiovascular diseases. To confirm the effects, if any, of calcium channel blockers on cirrhotic patients with portal hypertension, a study was performed on esophageal variceal pressure and rebleeding rate of esophageal varices after 2 years by using calcium channel blocker in 321 patients from some 23 hospitals. The results demonstrated that the calcium channel blockers could significantly reduce the esophageal variceal pressure and the portal blood flow in cirrhotic patients with portal hypertension. The proportion of patients with no recurrent gastrointestinal bleeding after 2 years medication of tetrandrine was 87.9% in tetrandrine group, significantly higher than those in the other 4 groups (P < 0.05). It is suggested that tetrandrine should be more effective for cirrhotic patients with portal hypertension in preventing recurrent variceal bleeding.
