Curcumin in the Treatment of Kidney Disease: A Systematic Review with a Focus on Drug Interactions

), attracts considerable interest as a potential therapy for KD due to its anti-inflammatory, antioxidant and anti-fibrotic properties. Despite the benefits of curcumin, co-administration with kidney medications may cause drug interactions. Here, we systematically reviewed the efficacy of curcumin in alleviating KD and its safety when used with conventional treatments. Search terms included: curcumin AND ("diabetic nephropathy" OR "renal disease" OR "kidney disease"). Data on mechanisms of action, redox status, clinical benefits, side effects, and drug interactions were extracted and analyzed. Curcumin reduces oxidative stress, inflammation, apoptosis, fibrosis, ER stress, and lipid and glucose metabolism. Curcumin has multifaceted nephroprotective effects, while it is safe and well-tolerated. The curcumin-drug interactions reviewed were: -piperine, -epigallocatechin gallate, -losartan, -ginkgolide B, -rosuvastatin, -insulin, -cilostazol, and -ginger. These interactions improve curcumin bioavailability, and synergistic anti-inflammatory/antioxidant/antifibrotic and renoprotective effects. Future research should prioritize large-scale clinical trials to evaluate the efficacy and safety of curcumin in diverse KD populations.
