Andrographis paniculata Extract and Andrographolide Modulate the Hepatic Drug Metabolism System and Plasma Tolbutamide Concentrations in Rats

Figure 4

Induction by ethanolic extract of Andrographis paniculata (APE) and andrographolide (AND) of the hepatic protein (a) and mRNA (b) expression of P-glycoprotein (P-gp). Rats were orally administered methyl cellulose (Con), APE, or AND for 5 days. Protein and mRNA levels in pooled liver samples ( ) are shown. Values shown are the mean ± SD, . The significance of the difference among group means was determined by one-way ANOVA followed by Tukey’s test. Values of treatments not sharing the same letter differ significantly, .
