ORETON vs TESTODERM TTS
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Androgen receptor agonist; binds to androgen receptors, stimulating protein synthesis, growth of male reproductive tissues, and development of secondary sexual characteristics.
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.
Testosterone enanthate 50-400 mg IM every 2-4 weeks.
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.

8 hours for testosterone; clinical context: requires daily or weekly dosing for replacement therapy
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.
Renal (90% as metabolites, 5% unchanged), biliary/fecal (10%)
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.
