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.
TLANDO (testosterone undecanoate) is an androgen that binds to and activates androgen receptors, leading to increased protein synthesis, muscle mass, bone density, and secondary sexual characteristics. Testosterone is converted to dihydrotestosterone (DHT) via 5α-reductase in target tissues, exerting both androgenic and anabolic effects.
12.5 mg orally twice daily
TLANDO (testosterone undecanoate) is administered orally. The recommended adult dose is 225 mg twice daily (approximately every 12 hours) with a meal containing fat. Swallow capsules whole; do not chew or crush.

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).
The terminal elimination half-life of testosterone is 10-100 minutes; however, for TLANDO (testosterone undecanoate) after oral administration, the apparent half-life is approximately 7-10 hours due to the slow release from chylomicrons and prolonged absorption.
Renal excretion of unchanged drug accounts for 60-70%; biliary/fecal excretion accounts for 20-30%; <10% metabolized.
Approximately 90% of a dose is excreted in urine as glucuronide and sulfate conjugates of testosterone and its metabolites; about 6% is excreted in feces via bile. Unchanged testosterone accounts for less than 1% of urinary excretion.
