概要

Estrogens oppose the estrogen-lowering action of exemestane, an aromatase inactivator used in hormone receptor-positive breast cancer. Coadministration may undermine its efficacy.

この相互作用をわかりやすく説明すると

Estradiol 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.

Estradiol belongs to Endocrine; Exemestane belongs to Oncology.

エビデンスレベル: Moderate

なぜ起こるのか

Pharmacodynamic antagonism: exogenous estradiol replaces the estrogen suppressed by exemestane.

対処法

Avoid concurrent systemic estrogen therapy with exemestane and use non-hormonal options for menopausal symptoms.
