Statins for treatment of asthma?

Statins are widely used to treat hyperlipidemia and their immunosuppressive effect has been confirmed in immune mediated disease models.

The effect of pravastatin (shown on the right) on allergic airway inflammation in a mouse model was examined focusing on its effect on IL17 production.

Pravastatin suppresses the systemic sensitisation to allergen with downregulation of IL17 production. It also suppresses the immune response in the airway by suppressing antigen presentation in the lung.

Therefore, statins could be a novel therapeutic option for treatment of asthma.
