FLUOXYMESTERONE vs TLANDO
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Synthetic androgen receptor agonist; binds to androgen receptors, modulating gene expression and promoting protein synthesis, muscle growth, and secondary sexual characteristic development.
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.
Adults: 5-20 mg orally once daily. For replacement therapy, 5-10 mg daily; for hypogonadism, 5-20 mg daily for several months.
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: 9.2 hours; clinical context: supports once-daily dosing for androgen replacement, with steady-state achieved in ~2 days
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: 90% as glucuronide and sulfate conjugates; fecal: 10%
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.
