Improving gallic acid and quercetin bioavailability by polymeric nanoparticle formulation

Abstract

The anticancer activity and pharmacokinetic properties of encapsulated polyherbal nanoparticles (gallic acid (GA) and quercetin nanocomposite) and polyherbal extract (amla and pomegranate fruit peels) in normal and DMH-induced colorectal cancer in rats were examined in this work. In normal and DMH-induced rats, a pharmacokinetic study demonstrated that polyherbal nanoparticles had a typical sustained release profile with a fourfold increase in bioavailability when compared to polyherbal extract. Based on serum–concentration profiles of polyherbal nanoparticles and polyherbal extract following oral administration, the pharmacokinetic parameters for polyherbal nanoparticles and polyherbal extract were established using a single compartmental approach. This research suggests that encapsulating GA and quercetin in polymeric nanoparticles improves their oral bioavailability and anti-colon cancer efficacy. Polymeric nanoparticles could be a novel therapeutic possibility for carcinogenesis prevention.
