Progestin-Only Contraceptive Slynd Gets FDA Approval

Slynd contains drospirenone, a spironolactone analogue.

The Food and Drug Administration (FDA) has approved Slynd (drospirenone; Exeltis) for use by females of reproductive potential to prevent pregnancy.

Slynd, a progestin-only oral contraceptive, lowers the risk of becoming pregnant primarily by suppressing ovulation. It contains the synthetic progestin drospirenone in a 4mg dosage strength that is given in a 24/4 dose regimen. Drospirenone is a spironolactone analogue with antimineralocorticoid and antiandrogenic activity.

The efficacy of Slynd in preventing pregnancy was evaluated in a single arm trial involving 953 female patients ≤35 years of age with 5547 evaluable cycles. Study findings showed that during these cycles, 1.8% of patients (n = 17) reported pregnancy, resulting in a Pearl Index of 4.0 (95% CI, 2.3-6.4).
