概要
Bosentan induces CYP3A4 and can lower hormonal contraceptive exposure, reducing contraceptive reliability. This is the opposite of the legacy direction, and drospirenone does not meaningfully affect bosentan.
この相互作用をわかりやすく説明すると
Bosentan and Drospirenone 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.
Bosentan belongs to Miscellaneous; Drospirenone belongs to Endocrine.
なぜ起こるのか
Bosentan induces CYP3A4, increasing the metabolism of drospirenone and other contraceptive steroids.
対処法
Do not rely on hormonal contraception alone during bosentan therapy; add or switch to a reliable non-hormonal method such as an intrauterine device or use dual methods.
