Sintesi

Exemestane works by lowering estrogen levels in postmenopausal women with hormone-sensitive breast cancer. Giving an estrogen-containing contraceptive at the same time supplies exogenous estrogen and can counteract the intended therapeutic effect. The pairing is also not appropriate in a patient with estrogen-dependent tumor.

Cosa significa questa interazione in parole semplici

Ethinyl estradiol-drospirenone and Exemestane can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.

Ethinyl estradiol-drospirenone belongs to Endocrine; Exemestane belongs to Oncology.

Livello di evidenza: Moderate

Perché avviene

Pharmacodynamic antagonism: exogenous ethinyl estradiol opposes the estrogen-lowering effect of aromatase inhibition.

Cosa fare

Avoid concurrent use of estrogen-containing products with exemestane. Use a non-hormonal method if contraception is needed.
