DEXEDRINE vs GOZELLIX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextroamphetamine is a central nervous system stimulant that enhances the activity of dopamine and norepinephrine in the brain by blocking their reuptake and increasing their release from presynaptic terminals.
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.
5–60 mg/day orally in divided doses, typically 5–20 mg 1–3 times daily; use immediate-release or extended-release formulations per indication.
250 mg subcutaneously once monthly.

Terminal elimination half-life is 4-6 hours for dextroamphetamine; clinical effects last longer due to CNS accumulation
Terminal elimination half-life: 14–16 hours in healthy adults; prolonged in renal impairment (up to 30 hours in ESRD).
Renal: 30-45% unchanged, 50-60% as deaminated metabolites; fecal: minor (<5%)
Primarily renal (approx. 80%) as unchanged drug; biliary/fecal excretion accounts for <5%.
