Pharmacology
Indication Testosterone propionate is an anabolic steroid and a short ester form of testosterone that becomes active in the body. It is often used for muscle mass building.
Mechanism of action The effects of testosterone in humans and other vertebrates occur by way of two main mechanisms: by activation of the androgen receptor (directly or as DHT), and by conversion to estradiol and activation of certain estrogen receptors. Free testosterone (T) is transported into the cytoplasm of target tissue cells, where it can bind to the androgen receptor, or can be reduced to 5α-dihydrotestosterone (DHT) by the cytoplasmic enzyme 5α-reductase. DHT binds to the same androgen receptor even more strongly than T, so that its androgenic potency is about 2.5 times that of T. The T-receptor or DHT-receptor complex undergoes a structural change that allows it to move into the cell nucleus and bind directly to specific nucleotide sequences of the chromosomal DNA. The areas of binding are called hormone response elements (HREs), and influence transcriptional activity of certain genes, producing the androgen effects.
Absorption Not Available
Protein binding 40% of testosterone in plasma is bound to sex hormone-binding globulin and 2% remains unbound and the rest is bound to albumin and other proteins.
Biotransformation Testosterone propionate is rapidly hydrolysed into testosterone. Testosterone is metabolized to 17-keto steroids through two different pathways. The major active metabolites are estradiol and dihydrotestosterone (DHT).
Route of elimination About 90% of a dose of testosterone given intramuscularly is excreted in the urine as glucuronic and sulfuric acid conjugates of testosterone and its metabolites; about 6% of a dose is excreted in the feces, mostly in the unconjugated form.
Toxicity Side effects include amnesia, anxiety, discolored hair, dizziness, dry skin, hirsutism, hostility, impaired urination, paresthesia, penis disorder, peripheral edema, sweating, and vasodilation.

Interactions
Drug Interactions
Drug Mechanism of interaction
Acenocoumarol The androgen, Testosterone, may incrase the anticoagulant effect of the Vitamin K antagonist, Acenocoumarol. Monitor for changes in the therapeutic effect of Acenocoumarol if Testosterone is initiated, discontinued or dose changed.
Cyclosporine The androgen, Testosterone, may increase the hepatotoxicity of Cyclosporine. Testosterone may also elevate serum concentrations of Cyclosporine. Consider alternate therapy or monitor for signs of renal and hepatic toxicity.
Docetaxel Testosterone propionate may increase the serum levels and toxicity of docetaxel.
Warfarin The androgen, Testosterone, may incrase the anticoagulant effect of the Vitamin K antagonist, Warfarin. Monitor for changes in the therapeutic effect of Warfarin if Testosterone is initiated, discontinued or dose changed.
