TESTODERM TTS vs TESULOID
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Testosterone is an androgen receptor agonist. It binds to and activates androgen receptors, leading to changes in gene expression that promote the development and maintenance of male secondary sexual characteristics, anabolic effects, and spermatogenesis.
Tesuloid is a monoclonal antibody that binds to and inhibits the activity of interleukin-23 (IL-23), thereby reducing pro-inflammatory cytokine production and immune-mediated inflammation.
Apply 4 mg (one 4 mg/24 hr system) or 6 mg (one 6 mg/24 hr system) transdermally once daily, applied to clean, dry, intact skin on the back, abdomen, thighs, or upper arms. Rotate application sites with an interval of at least 7 days.
Intravenous infusion of 500 mg over 60 minutes every 2 weeks.

The terminal elimination half-life of testosterone administered transdermally is approximately 1.5–2 hours. This short half-life requires daily application of the patch to maintain therapeutic levels.
16–20 hours in healthy adults; prolonged to 30–40 hours in moderate renal impairment (CrCl <50 mL/min); clinically significant accumulation risk in renal disease.
Testosterone is excreted primarily in the urine as glucuronide and sulfate conjugates (approximately 90%), with about 6% excreted in feces via bile. Less than 1% is excreted unchanged.
Primarily renal excretion (85% unchanged, 10% as glucuronide conjugate); 5% fecal.
