Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective estrogen receptor degrader (SERD); binds to estrogen receptor alpha, inducing degradation and inhibiting estrogen signaling.
Testosterone replacement therapy; binds to androgen receptors, promoting protein synthesis, muscle growth, and secondary sexual characteristic development.
12.5 mg orally twice daily
Intramuscular injection: 50-100 mg every 2-4 weeks.

Terminal elimination half-life is 4-6 hours in adults with normal renal function; prolonged to 10-12 hours in moderate renal impairment (CrCl <50 mL/min).
Terminal half-life 2.5-3.5 hours; clinical context: requires multiple daily dosing to maintain steady-state levels
Renal excretion of unchanged drug accounts for 60-70%; biliary/fecal excretion accounts for 20-30%; <10% metabolized.
Renal (90% as glucuronide and sulfate conjugates, 10% unchanged); Biliary/fecal (10%)
