Evaluation of atorvastatin and simvastatin for treatment of multiple sclerosis.
Atorvastatin and simvastatin (members of the 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitor family) are widely prescribed as cholesterol-lowering agents. As they have been shown to exhibit potent immunomodulatory effects, they may become a future treatment option for autoimmune disease in general and multiple sclerosis (MS) in particular. Several recent reports have demonstrated that statins prevent and reverse chronic and relapsing experimental autoimmune encephalomyelitis, an animal model of MS. An open-label clinical trial assessing simvastatin in MS revealed a significant decrease in the number and volume of new MRI lesions and a favorable safety profile. The results of a large multicenter, placebo-controlled clinical trial assessing atorvastatin in patients with clinically isolated syndrome (a disease that predisposes to development MS) are expected soon. However, prospective placebo-controlled trials of atorvastatin or simvastatin in definite MS are difficult to perform due to ethical and financial objections. In this review, we discuss the backgrounds, mechanisms of action and future perspectives of atorvastatin and simvastatin as putative future treatment options in MS.
