Mechanism and action
Ambien: Zolpidem is a positive allosteric modulator of the GABA-A receptor with relative selectivity for the alpha-1 subunit, which is associated with sedation and sleep induction. Aygestin: Norethindrone binds to progesterone receptors and exerts progestational effects: thickening cervical mucus, suppressing the LH surge, thinning the endometrium and reducing endometrial implant activity in endometriosis.
When Ambien is preferred
Ambien is approved in adults for the short-term treatment of insomnia, typically when difficulty falling asleep or maintaining sleep is associated with daytime impairment.
When Aygestin is preferred
Aygestin is approved for endometriosis-associated pain, abnormal uterine bleeding due to hormonal imbalance, and secondary amenorrhoea.
