The study aimed to prepare an optimized PIP-phospholipid complex (PPC) to enhance hepatoprotective activity and investigate its pharmacokinetics in an animal model. Results showed that PPC exhibited stronger hepatoprotective potential than pure PIP at the same dosage level, with improved bioavailability and elimination half-life in rat serum.
Piperspecies is one of the most widely consumed spices for culinary purposes. Piperine (PIP) present inPiperspecies has a wide range of therapeutic activity including hepatoprotection. However, the major biological limitation of PIP is its low bioavailability after oral administration. Purpose of the study was to prepare an optimized and adequately characterized PIP-phospholipid complex (PPC) as a delivery system to overcome these limitations and to investigate the pharmacokinetics and hepato-protectivity of the formulation in the animal model. Response surface methodology was adopted to optimize the process parameters for PPC preparation. FT-IR, DTA, PXRD, SEM, molecular docking etc. were used for characterization. Solubility, log P, dissolution efficiency andin vivopharmacokinetics were also investigated. PPC showed enhanced hepatoprotective potential as compared to pure PIP at the same dose level (25 and 50 mg/kg). PPC restored the levels of serum marker and antioxidant enzymes. PPC also increased the bioavailability of PIP in rat serum by 10.40-fold in comparison with pure PIP at the same dose level and enhanced the elimination half-life (t(1/2 el)) from 0.477 +/- 1.76 to 9.80 +/- 1.98 h. Results concluded that PPC enhanced the hepatoprotection of PIP which may be due to the improved bioavailability and pharmacokinetics of PIP in rats.
