Summary
Desogestrel is a safe and effective progestogen for combined oral contraceptives (OCs). Clinical trials show it lacks androgenicity and favorably impacts lipid metabolism, supporting its use in newer OC formulations.
Area of Science:
- Pharmacology
- Endocrinology
- Reproductive Health
Background:
- Desogestrel is a novel progestagen developed for oral contraceptives.
- Two combined oral contraceptive (OC) formulations incorporating desogestrel have been developed.
- These OCs combine desogestrel with ethinyl estradiol (EE) in varying dosages.
Purpose of the Study:
- To evaluate the safety and efficacy of desogestrel in combined oral contraceptives.
- To assess the androgenic potential of desogestrel.
- To investigate the effects of desogestrel on lipid metabolism, specifically HDL cholesterol levels.
Main Methods:
- Large-scale, multicenter clinical trials were conducted.
- Receptor studies were performed to confirm hormonal activity.
- Lipid metabolism studies analyzed effects on HDL cholesterol.
Main Results:
- No tablet failures were reported in clinical trials, indicating high efficacy.
- Desogestrel demonstrated a lack of androgenicity at the dosages used.
- Desogestrel did not negate the beneficial rise in HDL cholesterol induced by ethinyl estradiol.
Conclusions:
- Desogestrel is a potent and safe progestogen for combined oral contraceptives.
- Its favorable androgenic and lipid profiles make it a preferred choice for safer OC options.
- The progestogen desogestrel contributes positively to cardiovascular health markers in OCs.
