Venous Leg Ulcer? – Simvastatin 40 mg/day Speeds Healing

With  leg ulcers less that 5 cm size, all healed in simvastatin group versus 50% control. With ulcers over 5 cm, 67% of simvastatin group closed versus none of control group.

  • Venous ulcers up to age 85
  • 32 simvastatin; 34 control group
  • Simvastatin 40 mg/day
  • duration ulcers – over 3.8 years!
  • In simvastatin group, 90%  complete ulcer closure compared 34% in the control group (RR 0.158, 95% CI 0.053–0.474)
  • Healing time 9.17 +/- 1.07 wks
  • Their feeling is that inflammatory processes cause leg ulcers to persist and statins have anti-inflammatory properties. They also thought it helped tissue hypoxia.l_ulcers_infl

Comments – This is a huge benefit to leg venous ulcers. Simvastatin is highly lipophilic (dissolves in fat):

“simvastatin, which has the highest lipophilicity”

Rosuvastatin (crestor) is not – so potentially it might be better to stick with simvastatin.

Interestingly, simvastatin showed early suggestion that it could help heal MS plaque (being so lipophylic gets into brain easily):

They used 80 mg/day and got over 40% reduction in plaque MRI signals over 6 month.

Simvastatin has been found to inhibit certain inflammatory cytokines in MS:

Atorvastatin also works in the animal model of MS:
Weber, Martin S., et al.
Neither T-helper type 2 nor Foxp3+ regulatory T cells are necessary for therapeutic benefit of atorvastatin in treatment of central nervous system autoimmunity.
Journal of neuroinflammation 11.1 (2014): 29.

However MS patients on Interferon DO NOT benefit from statins in several trials. Recent bottom line was that no conclusion can be made because of “conflicting results”:

Having said that, a fat loving statin is be good for leg ulcers condition -but they also enter and effect the brain easily. Older people might find it causes some cognitive dysfunction while they are on it – and they will have to put up with that…
