Protective Effects of Propolis and Chitosan Nanoparticles against Ibuprofen-Induced Hepatotoxicity in Albino Rats

Abstract

Post-marketing hepatotoxicity findings are more common or occur much later. NSAIDs (non-steroidal anti-inflammatory drugs) like ibuprofen are consumed in large quantities around the world. NSAIDs have a low incidence of hepatotoxicity but their wide use makes them a major contributor to drug-induced liver injury. Hepatitis is linked to systemic oxidative stress which results in cellular necrosis and fibrosis, as well as tissue lipoprotein peroxidation and glutathione depletion. Given the lack of safe and effective anti-hepatitis drugs in medicine today, natural substances appear to be a promising and safe alternative. Propolis and chitosan are considered natural substances that have a protective effect on the hepatocytes. The purpose of this study was to validate the protective effect of propolis/chitosan nanoparticle extracts on ibuprofen-induced hepatotoxicity. Thirty (30) albino rats were used for the experiment. Animals were exposed to ibuprofen (400 mg/kg body weight/day) for 4 weeks (7 days/week) followed by treatment with propolis (200 mg/kg body weight/day) and chitosan extract (200 mg/kg body weight/day) separately and also in combination for consecutive 4 weeks. This study revealed a significant increase in serum transaminases, alkaline phosphatase, albumin, and total bilirubin in serum, as well as an increase in lipid peroxidation (MDA) and nitric oxide (NO). Furthermore, GSH, GST, and SOD decreased significantly in the group that was exposed to ibuprofen. Furthermore, there was a significant increase in pro-inflammatory parameters such as IL-1β and NF-ĸB, as well as low levels of anti-inflammatory parameters such as IL-6 and BCl-2. These alterations were improved by propolis and chitosan extracts, which was further confirmed in experimental animals. This study demonstrated that propolis and chitosan nanoparticle extracts have the potential to protect against hepatotoxicity induced by ibuprofen, due to their ability to regulate anti-inflammatory and anti-oxidative defense activities.
