DESOXYN vs GOZELLIX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Desoxyn (methamphetamine) is a sympathomimetic amine that promotes release of catecholamines (primarily dopamine and norepinephrine) from presynaptic nerve terminals, blocks their reuptake, and inhibits monoamine oxidase (MAO) activity. It produces CNS stimulation and peripheral alpha- and beta-adrenergic effects.
GOZELLIX (relugolix) is a gonadotropin-releasing hormone (GnRH) receptor antagonist. It competitively binds to GnRH receptors in the anterior pituitary gland, reducing the release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), thereby suppressing ovarian estrogen and testicular testosterone production.
Adults: 5-60 mg/day orally in divided doses, typically starting at 5 mg twice daily; maximum 60 mg/day.
250 mg subcutaneously once monthly.

Terminal elimination half-life: 9–14 hours (mean 12 hours) in adults; prolonged in alkaline urine (up to 25–30 hours). Clinically, twice-daily dosing maintains steady state after 2–3 days.
Terminal elimination half-life: 14–16 hours in healthy adults; prolonged in renal impairment (up to 30 hours in ESRD).
Renal: ~90% as unchanged drug and metabolites (primarily 4-hydroxyephedrine and 4-hydroxynorephedrine) within 48 hours; urinary pH-dependent: acidic urine increases elimination. Biliary/fecal: minor.
Primarily renal (approx. 80%) as unchanged drug; biliary/fecal excretion accounts for <5%.
