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… Neurontin: Gabapentin binds the alpha-2-delta auxiliary subunit of voltage-gated calcium channels in the central nervous system, reducing presynaptic calcium influx and the release of excitatory neurotransmitters such as glutamate…
When Propecia is preferred
Propecia is approved for the treatment of male pattern hair loss (androgenetic alopecia) in men aged 18 to 41.
When Neurontin is preferred
Neurontin is approved in adults and children aged 3 years and older as adjunctive therapy for partial-onset seizures, and in adults for post-herpetic neuralgia.
