GOZELLIX vs LISDEXAMFETAMINE DIMESYLATE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Lisdexamfetamine is a prodrug of dextroamphetamine, which blocks the reuptake of norepinephrine and dopamine from the synaptic cleft and increases their release into the extraneuronal space.
250 mg subcutaneously once monthly.
30–70 mg orally once daily in the morning.

Terminal elimination half-life: 14–16 hours in healthy adults; prolonged in renal impairment (up to 30 hours in ESRD).
Terminal elimination half-life of lisdexamfetamine is approximately 1 hour (prodrug conversion), while dextroamphetamine (active moiety) has a half-life of 10-12 hours in adults. In children, half-life is slightly shorter (9-11 hours). Clinically, once-daily dosing provides symptom control for ADHD.
Primarily renal (approx. 80%) as unchanged drug; biliary/fecal excretion accounts for <5%.
Primarily renal: approximately 95% of the dose is excreted in urine, with about 70% as intact lisdexamfetamine, 20% as dextroamphetamine and its metabolites (hippuric acid, benzoic acid), and minimal biliary/fecal elimination (<5%).
