ADZENYS XR-ODT vs GOZELLIX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Adzenys XR-ODT contains amphetamine, a central nervous system stimulant that increases extracellular levels of dopamine and norepinephrine by inhibiting their reuptake and promoting 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.
Initial: 9.4 mg orally once daily in the morning; titrate in increments of 9.4 mg per week based on tolerability and response. Maximum: 56.4 mg once daily.
250 mg subcutaneously once monthly.

Approximately 9-14 hours in adults, 8-11 hours in children (6-12 years). Extended-release pharmacokinetics produce a longer clinical duration compared to immediate-release formulations.
Terminal elimination half-life: 14–16 hours in healthy adults; prolonged in renal impairment (up to 30 hours in ESRD).
Renal: approximately 90% as unchanged drug and metabolites (30%-40% as amphetamine, 40%-50% as hippuric acid and benzoic acid). Fecal: <4%. Biliary: negligible.
Primarily renal (approx. 80%) as unchanged drug; biliary/fecal excretion accounts for <5%.
