Pharmacological properties
Pharmacodynamic properties
Testosterone Enanthate is an ester of testosterone. Testosterone is the primary androgenic hormone synthesized and released by the testes. Is responsible for the growth and development of male sex organs and secondary sexual characteristic features (aging prostate, seminal vesicles, penis, and scrotum), male hair distribution (face, groin, chest) develop laryngeal muscle and body fat distribution. Remember nitrogen, sodium, potassium and phosphorus, increase anabolism and decrease protein catabolism. The premature increase in serum testosterone in prepubertal epiphyseal closure and causes growth arrest. And Erythropoietin stimulates red blood cell production. The feedback mechanism inhibits the pituitary secretion of luteinizing hormone and follicle and causes suppression of spermatogenesis.
Women inhibit pituitary function, ovarian function, mammary glands, endometrial atrophy. Due to the action of estrogen antagonists used in the treatment of uterine myoma, endometriosis, breast cancer. Exhibit beneficial during the climacteric.
Pharmacokinetic properties
Testosterone Enanthate is slowly absorbed. Maximum plasma concentration are achieved in 72 hours after intramuscular administration. Duration of action - 2-4 weeks. In the blood about 98% of testosterone was coupled with a specific globulin fraction, which binds testosterone and estradiol. Biotransformation occurs in the liver to various 17-ketosteroizi that after conjugation with glucuronic or sulfuric acid is eliminated with urine (about 90%). Approximately 6% of the preparation is eliminated with feces absorbed in free-form.

Possible pain, itching and redness at the injection site.
Contraindications:
Individual hypersensitivity to the drug, prostate and breast carcinoma; prostate hyperplasia micturition disorder symptoms; nephrosis or the nephrotic phase of nephritis, edema; hypercalcemia; disturbances of liver function; diabetes; heart failure or coronary, myocardial infarction, atherosclerosis in elderly men; pregnancy, lactation.
Overdose
In acute overdose, the testosterone toxicity is very low.
In chronic overdose is possible to develop priapism. In this case, it is necessary to stop taking preparation, and after symptoms - resume with lower doses.
WARNINGS AND SPECIAL PRECAUTIONS FOR USE

Patients with latent or overt cardiac failure, impaired renal function, hypertension, epilepsy or migraine (or a history of the presence of these states) will be under constant supervision because androgens may cause sodium retention and in some cases water. The treatment duration will monitor liver function. At breast cancer patients, hipernefrom lung cancer bone metastases will control the level of calcium in the blood and urine. Androgens in prepubertal adolescents should be given with caution to avoid premature cessation of growth and puberty.
Interactions with other drugs:
Increase the effectiveness of anticoagulants and antidiabetic (dose adjustment is required), inhibits cyclosporine elimination. Hepatic enzyme inducers (barbiturates, rifampin, carbamazepine, phenylbutazone, phenytoin) reduce the effect of testosterone.
