چکیده انگلیسی
Andrographolide (AND) is one of diterpenoids separated from Andrographis paniculata with a wide spectrum of biological activities of being anti-inflammatory, anticancer, hepatoprotective, and antihyperlipidemic. But its poor water solubility and instability resulted in lower bioavailability and seriously limited its pharmacological function. In this study, AND-loaded solid lipid nanoparticles (AND-SLNs) were prepared by a high-pressure homogenization method and presented as spherically shaped under transmission electron microscopy with an average diameter of 286.1 nm and zeta potential of â 20.8 mV. The average drug-entrapment efficiency and drug loading were 91.00% and 3.49%, respectively. The results indicated that the lower bioavailability of AND is not only because of the poor solubility but also owing to its metabolic instability in intestinal segments. Furthermore, the transport mechanism of AND in Caco-2 cell model is complex in which an active transport carrier (P-glycoprotein) is involved in. The bioavailability and antihyperlipidemic activity of AND were improved by AND-SLNs by increasing the solubility and stability of AND in the intestine and by changing its transport mode in Caco-2 cell. The bioavailability of AND was increased to 241% by AND-SLNs as compared with AND suspension. AND-SLNs would be a promising drug-delivery system to enhance the oral absorption and bioavailability of AND.
