DEXAMPEX vs GOZELLIX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextroamphetamine is a central nervous system stimulant that increases extracellular dopamine and norepinephrine levels by blocking their reuptake and promoting 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.
5-10 mg orally once daily in the morning, maximum 20 mg/day.
250 mg subcutaneously once monthly.

Terminal elimination half-life 10–13 hours in adults (7–8 hours in children). Longer in alkaline urine (up to 20 hours) due to reduced renal tubular reabsorption.
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 deaminated metabolites); fecal/biliary <2%.
Primarily renal (approx. 80%) as unchanged drug; biliary/fecal excretion accounts for <5%.
