Overview of APIs in Lessina-28

Ethinylestradiol

Ethinylestradiol (EE) is a synthetic estrogen and a cornerstone API in combined oral contraceptives. Its synthesis requires complex chemical processes involving multiple steps, including the preparation of estrogenic cores and subsequent functionalization.

Drospirenone

Drospirenone (DRSP) is a synthetic progestin with antimineralocorticoid properties. Its synthesis is more intricate due to its unique chemical structure resembling spironolactone, demanding specialized manufacturing expertise.
