Key differences
Neurontin belongs to Neurological Medications while Addyi belongs to Women's Sexual Health. Indications, mechanisms and target populations differ. The comparison is most useful when a clinician has mentioned both medications and the patient wants to understand where each fits.
Mechanism and action
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… Addyi: Sexual desire is modulated by complex central nervous system pathways involving serotonin (generally inhibitory) and dopamine and norepinephrine (generally excitatory).
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.
When Addyi is preferred
Addyi is indicated for the treatment of acquired, generalised hypoactive sexual desire disorder (HSDD) in premenopausal women.
