DYANAVEL XR vs GOZELLIX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dyanavel XR is a central nervous system stimulant that increases the levels of dopamine and norepinephrine in the synaptic cleft by inhibiting their reuptake and increasing their release, thereby enhancing neurotransmission in the brain regions involved in attention and impulse control.
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 dose: 5 mg orally once daily in the morning. Maximum dose: 20 mg once daily. May increase by 5–10 mg weekly based on tolerability and response.
250 mg subcutaneously once monthly.

Mean terminal elimination half-life is approximately 8-10 hours for d-amphetamine and 12-14 hours for l-amphetamine; the extended-release formulation maintains therapeutic concentrations for 12-14 hours.
Terminal elimination half-life: 14–16 hours in healthy adults; prolonged in renal impairment (up to 30 hours in ESRD).
Approximately 30-50% of a dose is excreted unchanged in urine; remainder as metabolites (primarily hippuric acid) via renal elimination. Fecal excretion is minimal.
Primarily renal (approx. 80%) as unchanged drug; biliary/fecal excretion accounts for <5%.
