ABSTRACT
AIM:
To study the effect of Lomerizine on the activity of P-glycoprotein (P-gp) in the bloodbrain barrier(BBB) and search for novel effective P-gp inhibiting agent against multidrug resistance. METH-ODS Rhodamine123 (Rh123) was used to examine the activity of P-gp and RT-PCR to study the mdr mRNA expression in cultured rat brain microvessel endothelial cells (RBMECs).RESULTS:
Lomerizine could increase the cellular Rh123 in RBMECs in a concentration-dependent manner. RT-PCR indicated that lomerizine could not down-regulate the expression of mdr mRNA. CONCLU-SION Lomerizine can reverse multidrug resistance in the blood-brain barrier by inhibiting the activity of P-gp.KEY WORDS lomerizine; P-glycoprotein; bloodbrain barrier; RT-PCR
