Introduction to Pharmacological Profile
Ethinyl Estradiol (EE):
A synthetic estrogen used widely in oral contraceptives, hormone replacement therapy, and other hormonal treatments. It is a cornerstone in combined hormonal contraceptives (CHCs) with extensive historical safety data.
Segesterone Acetate (SA):
A progestin with sustained-release properties, under minimal systemic absorption when formulated appropriately. Originally developed for contraceptive use, it is notable for its efficacy and safety profile. Recently, its combination with EE has attracted interest for novel delivery systems.
