Testosterone Cypionate – Clinical Pharmacology

Endogenous androgens are responsible for the normal growth and development of the male sex organs and the maintenance of secondary sex characteristics. These effects include growth and maturation of the prostate, seminal vesicles, penis, and scrotum; development of male hair distribution, such as beard, pubic, chest, and axillary hair; laryngeal enlargement, vocal cord thickening, and alterations in body musculature and fat distribution.

Drugs in this class also cause retention of nitrogen, sodium, potassium, and phosphorous, decreasing urinary excretion of calcium. Androgens have been reported to increase protein anabolism and decrease protein catabolism. Nitrogen balance is improved only when there is a sufficient intake of calories and protein.

Androgens are responsible for the growth spurt of adolescence and the eventual termination of linear growth brought about by the fusion of the epiphyseal growth centers. In children, exogenous androgens accelerate linear growth rates but may cause a disproportionate advancement in bone maturation.

Use over long periods may result in the fusion of the epiphyseal growth centers and termination of the growth process. Androgens have been reported to stimulate the production of red blood cells by enhancing the production of the erythropoietic stimulation factor. During exogenous administration of androgens, endogenous testosterone release is inhibited through pituitary luteinizing hormone (LH) feedback inhibition.

At large doses of exogenous androgens, spermatogenesis may also be suppressed through feedback inhibition of pituitary follicle stimulating hormone (FSH). There is no substantial evidence that androgens are effective in fractures, surgery, recovery, and functional uterine bleeding.

Pharmacokinetics

Testosterone esters are less polar than free testosterone. Testosterone esters in oil injected intramuscularly are absorbed slowly from the lipid phase; thus, Testosterone Cypionate can be given at two to four weeks intervals. Testosterone in plasma is 98 percent bound to a specific testosterone-estradiol binding globulin, and about 2 percent is free. Generally, the amount of this sex-hormone binding globulin in the plasma will determine the distribution of testosterone between free and bound forms, and the free testosterone concentration will determine its half-life.

About 90 percent of a dose of testosterone injections is excreted in the urine as glucuronic and sulfuric acid conjugates of testosterone and its metabolites; about 6 percent of an amount is excreted in the feces, mostly in the unconjugated form.

The inactivation of testosterone occurs primarily in the liver. Testosterone therapy is metabolized to various 17-keto steroids through two different pathways. The half-life of Testosterone Cypionate, when injected intramuscularly, is approximately eight days.

In many tissues, the activity of testosterone therapy depends on the reduction of dihydrotestosterone, which binds to cytosol receptor proteins.

The steroid-receptor complex is transported to the nucleus, which initiates transcription events and cellular changes related to androgen action.

Indications and Usage for Testosterone Cypionate Description

Testosterone Cypionate description injection is indicated for replacement therapy in the male in conditions associated with symptoms of deficiency or absence of endogenous testosterone.

  • Primary hypogonadism (congenital or acquired) is testicular failure due to cryptorchidism, bilateral torsion, orchitis, vanishing testis syndrome, orchidectomy.
  • Hypogonadotropic hypogonadism (congenital or acquired): gonadotropin, LHRH deficiency, pituitary-hypothalamic injury from tumors, trauma, or radiation.

The safety and efficacy of Testosterone Cypionate description in men with “age-related hypogonadism” (also referred to as “late-onset hypogonadism”) have not been established.

Contraindications

  1. Known hypersensitivity to the drug
  2. Males with carcinoma of the breast
  3. Males with known or suspected carcinoma of the prostate gland
  4. Women who are or who may become pregnant
  5. Patients with serious cardiac, hepatic, or renal disease

Warnings

Hypercalcemia may occur in immobilized patients. If this happens, the drug should be discontinued.

Prolonged high doses of androgens (principally the 17-α alkyl-androgens) have been associated with developing hepatic adenomas, hepatocellular carcinoma, and peliosis hepatis —all potentially life-threatening complications. Geriatric patients treated with androgens may be at an increased risk of developing prostatic hypertrophy and prostatic carcinoma, although conclusive evidence to support this concept is lacking. There have been postmarketing reports of venous thromboembolic events, including deep vein thrombosis (DVT) and pulmonary embolism (PE), in patients using testosterone products, such as Testosterone Cypionate description.

Evaluate patients who report symptoms of pain, edema, warmth, and erythema in the lower extremity for DVT and those who present with acute shortness of breath for PE. If a venous thromboembolic event is suspected, discontinue treatment with Testosterone Cypionate description and initiate appropriate workup and management. Long-term clinical safety trials have not been conducted to assess the cardiovascular outcomes of testosterone replacement therapy in men.

To date, epidemiologic studies and randomized controlled trials have been inconclusive in determining the risk of major adverse cardiovascular events (MACE), such as non-fatal myocardial infarction, non-fatal stroke, and cardiovascular death, using testosterone compared to non-use. Some studies, but not all, have reported an increased risk of MACE in association with the help of testosterone replacement therapy in men.

Patients should be informed of this possible risk when deciding whether to use or continue the Testosterone Cypionate description. Edema, with or without congestive heart failure, may be a serious complication in patients with preexisting cardiac, renal, or hepatic disease. Gynecomastia may develop and occasionally persists in patients being treated for hypogonadism.

The preservative benzyl alcohol has been associated with serious adverse events, including the “gasping syndrome” and death in pediatric patients. Although normal therapeutic doses of this product ordinarily deliver amounts of benzyl alcohol that are substantially lower than those reported in association with the “gasping syndrome,” the minimum amount of benzyl alcohol at which toxicity may occur is unknown.

The risk of benzyl alcohol toxicity depends on the quantity administered and the hepatic capacity to detoxify the chemical. Premature and low-birthweight infants may be more likely to develop toxicity. Androgen therapy should be used cautiously in healthy males with delayed puberty. The effect on bone maturation should be monitored by assessing the bone age of the wrist and hand every six months. In children, androgen treatment may accelerate bone maturation without producing a compensatory gain in linear growth. This adverse effect may result in compromised adult stature.

The younger the child, the greater the risk of compromising final mature height. This drug is not safe and effective for enhancing athletic performance. This drug should not be used because of the potential risk of serious adverse health effects.

Precautions

Patients with benign prostatic hypertrophy may develop acute urethral obstruction. Priapism or excessive sexual stimulation may develop. Oligospermia may occur after prolonged administration or excessive dosage. If any of these effects appear, the androgen should be stopped, and if restarted, a lower dosage should be utilized. Testosterone Cypionate description should not be used interchangeably with testosterone propionate description because of differences in duration of action. Testosterone Cypionate description is not for intravenous use.

Information for Patients

Patients should be instructed to report any of the following: nausea, vomiting, changes in skin color, ankle swelling, too frequent erections of the penis.

Laboratory Tests

Hemoglobin and hematocrit levels (to detect polycythemia) should be checked periodically in long-term androgen administration patients. Serum cholesterol may increase during androgen therapy.

Drug Interactions

Androgens may increase sensitivity to oral anticoagulants. The anticoagulant dosage may require a reduction to maintain satisfactory therapeutic hypoprothrombinemia. Concurrent administration of oxyphenbutazone and androgens may result in elevated serum levels of oxyphenbutazone. In diabetic patients, the metabolic effects of androgens may decrease blood glucose and, therefore, insulin requirements.

Drug/Laboratory Test Interferences

Androgens may decrease levels of thyroxine-binding globulin, resulting in decreased total T4 serum levels and increased resin uptake of T3 and T4. However, free thyroid hormone levels remain unchanged, and there is no clinical evidence of thyroid dysfunction.

Carcinogenesis

Animal data Testosterone has been tested by subcutaneous injection and implantation in mice and rats—the implant induced cervical-uterine tumors in mice, which metastasized in some cases. There is suggestive evidence that injecting testosterone into some strains of female mice increases their susceptibility to hepatoma. Testosterone is also known to increase the number of tumors and decrease the degree of differentiation of chemically induced liver carcinomas in rats.

Human data There are rare reports of hepatocellular carcinoma in patients receiving long-term therapy with androgens in high doses. Withdrawal of the drugs did not lead to regression of the tumors in all cases. Geriatric patients treated with androgens may be at an increased risk of developing prostatic hypertrophy and prostatic carcinoma, although conclusive evidence to support this concept is lacking.

Pregnancy

Teratogenic Effects Pregnancy Category X. (See CONTRAINDICATIONS) Benzyl alcohol can cross the placenta.

SEE WARNINGS.

Nursing Mothers

Testosterone Cypionate description is not recommended for use in nursing mothers.

Pediatric Use

Safety and effectiveness in pediatric patients below the age of 12 years have not been established.

Adverse Reactions

The following adverse reactions in the male have occurred with some androgens.
