DYANAVEL XR 15 vs GOZELLIX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dyanavel XR contains amphetamine, which is a central nervous system stimulant that increases synaptic concentrations 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.
1-3 capsules orally once daily in the morning. Each capsule contains 15 mg of amphetamine (equivalent to 15 mg dextroamphetamine/amphetamine).
250 mg subcutaneously once monthly.

Terminal elimination half-life: amphetamine (d-isomer) 9-11 hours, l-isomer 11-14 hours; allows for once-daily dosing in extended-release formulation
Terminal elimination half-life: 14–16 hours in healthy adults; prolonged in renal impairment (up to 30 hours in ESRD).
Renal (80-90% as unchanged drug and metabolites, primarily dehydro-amphetamine); fecal excretion minimal (<5%)
Primarily renal (approx. 80%) as unchanged drug; biliary/fecal excretion accounts for <5%.
