FORTESTA vs TLANDO
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Testosterone replacement therapy; testosterone binds to and activates androgen receptors, influencing gene transcription and protein synthesis, leading to the development of male secondary sex characteristics and maintenance of libido, muscle mass, and bone density.
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.
Apply one 30 mg metered-dose transdermal system to abdomen or upper arm once daily at the same time each day.
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 3–4 hours; not clinically significant for once-daily transdermal administration due to sustained absorption.
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.
Primarily renal (90% as glucuronide and sulfate conjugates, 10% unchanged); approximately 1% fecal.
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.
