Hormonal Lovastatin

Endocrine effects Statins interfere with cholesterol synthesis and lower circulating cholesterol levels and, as such, might theoretically blunt adrenal or gonadal steroid hormone production. Small declines in total testosterone with no commensurate elevation in LH have been noted with the use of fluvastatin. Pravastatin showed inconsistent results with regard to possible effects on basal steroid hormone levels atorvastatin, lovastatin, rosuvastatin, and simvastatin did not reduce basal plasma cortisol concentration or basal plasma testosterone concentration or impair adrenal reserve. Appropriately evaluate patients who display clinical evidence of endocrine dysfunction. Exercise caution when administering HMG-CoA reductase inhibitors with drugs that affect steroid levels or activity, such as ketoconazole, spironolactone, and cimetidine.

An isolated report describes raised serum thyroid hormone levels and evidence of thyrotoxicosis in a man taking levothyroxine with lovastatin. In contrast another isolated case report describes hypothyroidism in a woman taking levothyroxine with lovastatin. Another report describes reduced efficacy of levothyroxine in two patients taking simvastatin, one of whom was successfully treated with pravastatin.
