Mechanism and action
Propecia: DHT, produced from testosterone by 5-alpha-reductase, drives miniaturisation of scalp hair follicles in genetically susceptible men, gradually shortening anagen growth phases until follicles produce only fine vellus hair… 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.
When Propecia is preferred
Propecia is approved for the treatment of male pattern hair loss (androgenetic alopecia) in men aged 18 to 41.
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.
