Understanding Levonorgestrel: The API in PLAN B

Levonorgestrel is a synthetic progestin used as a hormonal contraceptive. Its role in PLAN B is to inhibit ovulation, preventing fertilization or implantation. The API's purity (>99%) and consistent bioavailability are paramount, as deviations can compromise contraceptive effectiveness or trigger adverse effects.

Ensuring high-quality API sourcing is crucial for pharmaceutical companies to maintain regulatory compliance, reduce supply chain risks, and meet global demand efficiently.
