Calcineurin inhibitors are helpful immunosuppressive agents in clinical practice. Thanks to their lower cost respect with new immunosuppressive therapy, calcineurin inhibitors in our country continue being the most used treatment in solid organ transplant recipients or patients with autoimmune disease. In the 80's decade cyclosporine A (CsA) was introduced as the first calcineurin inhibitor transforming the immunosuppression therapy. Up to date, many articles evaluating beneficial and adverse effects of CsA have been published. In this review, basic aspects and actions of CsA are analyzed together with studies from our laboratory that pointed out the pathophysiological role of aldosterone as a mediator of functional and structural changes that are observed in CsA nephrotoxicity. Based in our findings, we proposed that in CsA nephrotoxicity, the aldosterone mediates renal vasoconstriction and enhances TGFbeta expression promoting the development of nefrotoxicity. Finally, results from our laboratory and others allow us to suggest that aldosterone receptors blockade with spironolactone or eplerone could be a pharmacological therapy to reduce or prevent acute and chronic CsA nephrotoxicity in transplant recipients.
