To survey the penetrance of Nimodipine to blood-pancreatic barrier. Pancreatic fluid of 15 cases with pancreatic diseases were respectively sampled from pancreatic drainage tubes at different time after Nimodipine taken orally, and the concentrations of Nimodipine in the fluid were measured with high performance liquid chromatography (HPLC). The average concentration of Nimodipine in pancreatic fluid at 0.5,1,1.5,2,2.5,3,3.5,4 hours after Nimodipine administration were 4.79,7.31,9.21,8.04,6.05,5.11,3.37 and 1.19 ng/ml, respectively. The highest value of Nimodipine level in pancreatic fluid were 9.21 ng/ml at 1.5 to 2 hours following Nimodipine taken orally. These suggested that the Nimodipine can penetrate across the bloodpancreatic barrier and make its pharmacolohical effect in pancreatic tissue.
