Inflammatory bowel disease (IBD) is a chronic disease that affects quality of life. Various mediators are involved in IBD pathogenesis including inducible nitric oxide synthase (iNOS), nuclear factor kappa B (NF-κB), cytochrome c, heat shock protein 70 (HSP70) and tumor necrosis factor (TNF)-α. L-Arginine (L-Arg) can be depleted in IBD, and silymarin inhibits neutrophil infiltration, NF-κB, and TNF-α, which have crucial roles in inducing IBD.

Introduction: In addition to their lipid-lowering effect, statins have pleiotropic effects that may extend their use to the treatment and prevention of various other diseases such as cancer, osteoporosis, multiple sclerosis, rheumatoid arthritis, type 2 diabetes, and Alzheimer's disease. Consequently, the number of patients taking statins is expected to increase. A side effect of statins, statin-induced myopathy, which may result from reduced muscular coenzyme Q10 levels, limits their use.
