Aqueous extract of Kalanchoe pinnata leaves had immunosupressant effect on lupus nephritis model. When it combined with methylprednisolone, there is a risk of interaction. In this study rats divided into two groups, a group that received methylprednisolone (MP) (0.72?mg/kgBW) and a group that received MP in combination with extract (0.36?mg/kg BW MP and 140?mg/kg BW extract). These treatment were given everyday for 4 weeks. Methylprednisolone concentration in rats serum was measured using HPLC with extraction method according to Lawson method (1985). The column used was Inertsil C-18 using mobile phase KH2PO4 : metanol (15:85) buffer, flow rate 0.6?mL/minutes, UV detector (? = 230?nm) and pressure 1319 psi. The result showed that there was an interaction occurred. The combination of MP and aqueous extract of K. pinnata leaves showed interaction which causing methylprednisolone level comparable with methylprednisolone level in MP group. Mean of decreasing MP level in serum was 0.285?ppm. It means that aqueous extract of Kalanchoe Folium could elevate methylprednisolone concentration in plasma. Adjustment of the dose must be considered in this combination.
