[Preparation of oral berberine bisulfate liposomes].
The co-precipitate has been made from berberine bisulfate and polyvingyl pyrrolidone (PVP) with the ratio of 1 : 5. The liposomes entrapped berberine bisulfate have been prepared with the ration of drug to lipid 1 : 20 and the ratio of cholesterol to soy phosphatide 2 : 7. The percentage of encapsulation is 48.72%. The test in vivo of small intestinal absorption in rats shows that liposomes can increase the absorption by 4-fold odd compared with free ber-berine bisulfate.
