AMPHETAMINE SULFATE vs GOZELLIX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Increases presynaptic release of dopamine and norepinephrine, blocks reuptake, and inhibits monoamine oxidase, resulting in CNS stimulation.
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 1–3 divided doses, initial 5 mg once or twice daily, increase by 5 mg weekly.
250 mg subcutaneously once monthly.

Terminal elimination half-life: 10-13 hours in adults with acidic urine; prolonged to 16-34 hours with alkaline urine. In children, half-life is typically shorter (6-8 hours).
Terminal elimination half-life: 14–16 hours in healthy adults; prolonged in renal impairment (up to 30 hours in ESRD).
Renal excretion of unchanged amphetamine (approximately 30-40%) and its metabolites; urinary pH-dependent: acidic urine enhances elimination (up to 70% unchanged), alkaline urine reduces it. Minor biliary/fecal elimination (<10%).
Primarily renal (approx. 80%) as unchanged drug; biliary/fecal excretion accounts for <5%.
