It can reduce the bioavailability of some drugs, and it is also one of the important causes for multidrug resistance of tumor cells. Some pharmaceutical excipients can inhibit P-gp mediated ef? ux, and they simultaneously have the advantages of low toxicity, no pharmacological activity and high safety. This paper emphasizes on the progress of three kinds of pharmaceutical excipients (non-ionic surfactants, polymers and lipids) with the function of inhibition of P-gy mediated ef? ux. Meanwhile the structure, function and research model of P-gp are brie? y introduced. Key Words: pharmaceutical excipient; P-glycoprotein; ef? ux; inhibition; review P- 糖蛋白 (P-glycoprotein，P-gp) 是一种分 那韦 (saquinavir) 及地高辛 (digoxin) 等。因此，开 子量为 170 000 的跨膜糖蛋白，广泛分布在肝脏、 发 P-gp 抑制
