Contraception
January 2011
Article Synopsis
- The study evaluated the blood concentrations and accumulation of levonorgestrel (LNG) and ethinyl estradiol (EE) in a new extended-regimen 91-day oral contraceptive.
- Conducted with 30 healthy female volunteers, participants took daily doses of LNG/EE for 84 days, followed by EE alone, with pharmacokinetic monitoring at various intervals.
- Results showed that the hormone levels after 84 days were similar to those seen at 21 days, indicating that the extended regimen does not cause additional accumulation compared to the traditional 28-day regimen.
