Development of Phytosome Loaded with Pandanus amaryllifolius Roxb Extract with its LC–MS Approach against Azithromycin Induced Cardiotoxicity in Rats
摘要
This study evaluates the cardioprotective potential of Pandanus amaryllifolius leaf extract and its phytosomal formulation against azithromycin-induced cardiotoxicity in Wistar rats. Phytochemical analysis via LC–MS identified bioactive compounds including kaempferol and pandamarine. Antioxidant potential was confirmed through DPPH assay (IC₅₀ = 72.9 µg/mL), total phenolic content (34.42 mg GAE/g), and total flavonoid content (17.85 mg QE/g). Phytosomes were optimized for particle size (253.9 nm) and zeta potential (− 0.53 mV) and characterized using FTIR and TEM. Rats received azithromycin (30 mg/kg) with or without extract (100, 200, 400 mg/kg) or phytosomal formulation. Azithromycin elevated QT interval, heart weight, serum CK-MB, LDH, lipid profile, and malondialdehyde, while reducing SOD, GSH, and HDL levels. Both extract and formulation significantly restored ECG parameters, antioxidant enzyme activity, lipid profile, and reduced myocardial damage, with the phytosomal formulation showing superior effects. Histopathology confirmed preservation of myocardial architecture in treated groups, particularly with phytosomes. Findings suggest Pandanus amaryllifolius exerts cardioprotection via antioxidant, anti-inflammatory, and lipid-lowering mechanisms, enhanced by phytosomal delivery. This natural therapeutic shows promise in preventing drug-induced cardiotoxicity, warranting further molecular and clinical evaluation.
