Itraconazole induced hypertension and hypokalemia: Mechanistic evaluation.

We describe a case of apparent mineralocorticoid excess (hypertension, hypokalemia, metabolic alkalosis and low plasma renin activity) secondary to itraconazole therapy. Inhibition of 11β-hydroxysteroid dehydrogenase 2 was demonstrated, and withholding itraconazole led to resolution of adverse effects that did not recur with voriconazole. This report adds to a growing body of evidence linking apparent mineralocorticoid excess with certain triazoles.
