    Area of Science:

    • Reproductive endocrinology
    • Pharmacology

    Context:

    • The antiprogestin RU 486 (mifepristone) alters uterine function during early pregnancy.
    • Nonsurgical abortion methods increasingly utilize hormonal interventions.

    Purpose:

    • To review the mechanism of action of RU 486 in early pregnancy.
    • To discuss its application in combination with prostaglandins for abortion.
    • To explore other clinical implications of RU 486.

    Summary:

    • RU 486 increases myometrial sensitivity to prostaglandins (PG), facilitating uterine contractions.
    • Combined with PG analogues, it forms the basis for early-term nonsurgical abortions.
    • Cervical softening by RU 486 is beneficial for second and third-trimester abortions.

    Impact:

    • RU 486 has revolutionized early pregnancy termination options.
    • Understanding its effects is crucial for reproductive health and safety.
    • Potential broader clinical uses and risks warrant further investigation.
