Norgestimate is a third-generation synthetic progestin used in combination oral contraceptives. It is a derivative of 19-nortestosterone and is considered to have low androgenic activity, making it a preferred choice for women sensitive to androgenic side effects such as acne or hirsutism. Once ingested, norgestimate is rapidly converted to its active metabolites (primarily norelgestromin and levonorgestrel-like compounds) that exert contraceptive effects.
It is used in combination with ethinylestradiol to prevent pregnancy and is also prescribed off-label for hormonal acne and menstrual regulation.
Indications include:
∙ Oral contraception
∙ Management of acne vulgaris in females
∙ Menstrual cycle regulation and dysmenorrhea

Impurities in norgestimate may arise from its complex multi-step semi-synthetic production, which involves selective oxidation, acetylation, and hydroxylation. Its impurity profile must meet ICH Q3A/B and USP/EP standards due to its chronic administration.

Norgestimate is used in combination birth control pills to prevent pregnancy and is also effective in treating acne, regulating periods, and managing hormonal imbalances.
It prevents ovulation, thickens cervical mucus to block sperm, and alters the endometrial lining to prevent implantation of a fertilized egg.
It is generally well tolerated but may not be suitable for women with a history of thromboembolic disorders, liver disease, or certain hormone-sensitive cancers.
Yes, under cool, dry conditions, but it is light-sensitive and should be stored in its original packaging to maintain potency.
