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.
Androgen receptor agonist; binds to androgen receptors, stimulating protein synthesis, growth of male reproductive tissues, and development of secondary sexual characteristics.

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).
8 hours for testosterone; clinical context: requires daily or weekly dosing for replacement therapy
Renal excretion of unchanged drug accounts for 60-70%; biliary/fecal excretion accounts for 20-30%; <10% metabolized.
