Statins in Diabetic Foot Ulcer Healing: From Biological Mechanisms to Clinical Evidence. A Comprehensive Literature Review.

Diabetic foot ulcers are a serious complication of diabetes that can lead to amputation, making better treatments essential. This review explored whether statins—drugs commonly prescribed to lower cholesterol—might also aid wound healing. In laboratory studies, statins consistently improved healing by enhancing blood flow, promoting new blood vessel growth, and increasing collagen, a protein that strengthens tissue. However, clinical evidence from patient studies is mixed: some observational studies found no clear benefit, while certain randomized trials suggested fewer ulcer recurrences. The authors conclude that statins show promise but require more high-quality human trials before they can be recommended specifically for ulcer healing. Importantly, statins are currently prescribed for heart health, not wound care, and patients should not start them for this purpose without consulting their doctor. New delivery methods like topical creams and scaffolds are being investigated to target statin effects directly at the wound site.
