Aim of the study: The primary aim of this study was to evaluate the possible pharmacokinetic and pharmacodynamics (anti-inflammatory) herb-drug interaction of Andrographolide (AN) with meloxicam (Melx) in Wistar rats. Materials and methods: A sensitive and validated RP-HPLC method was developed for the simultaneous estimation of AN and Melx in rat plasma. The oral administration of AN (60mg/kg), Melx 1.55mg/kg) and co-admin group in male-Wistar rats were given. The plasma drug concentration was evaluated using the RP-HPLC method and the pharmacokinetic parameters such as Cmax, Tmax, MRT, T½, CL, Vd, and AUC were calculated. Pharmacodynamic parameters such as Change in paw volume, mechanical hyperalgesia, and mechanical nociceptive threshold were evaluated for predicting the herb-drug interaction.
