Pharma

Description

TESTO-PHARM 100 (Testosterone Propionate Injection 100 mg/ml) is Clear, Colourless, oily liquid for Intramuscular use. Each ml contains Testosterone Propionate 100 mg.

Pharmacodynamics

The esterification of testosterone at the 176-hydroxy position makes the molecule hydrophobic and extends its duration of action. The slow release of testosterone ester from an oily depot in the muscle accounts for its extended duration of action. The longer the side chain, the greater the hydrophobicity of the ester, and the longer the duration of action.

Indications and Usage

The primary indication for androgens, such as testosterone or its esters, is as replacement therapy in male hypogonadal disorders caused by either pituitary or testicular disorders or in hypogonadism following orchidectomy. Androgens and anabolic steroids have sometimes been used with oestrogens in the management of certain menopausal disorders, but the use of androgens and anabolic steroids in women with osteoporosis is no longer advocated because their adverse effects essentially outweigh any benefit they may produce

Dosage and Administration

The testosterone esters are usually formulated as oily solutions for intramuscular use to give a prolonged duration of action. Testosterone propionate up to 50 mg two or three times weekly or 100 mg once in a week is recommended.

Adverse effects

Testosterone and other androgens may give rise to adverse effects related to their androgenic or anabolic activities. These include increased retention of sodium and water, oedema, hypercalcaemia, and impaired glucose tolerance. Other effects include increased low density- lipoprotein cholesterol, decreased high-density- lipoprotein cholesterol, increased haematocrit, and suppression of clotting factors. Androgens may cause headache, depression, and gastrointestinal bleeding. It has been suggested that androgens may induce sleep apnoea in susceptible patients. Abnormal liver function tests may occur and there have been reports of liver toxicity including jaundice and cholestatic hepatitis. There have also been reports of peliosis hepatis and hepatic tumours in patients who have received high doses over prolonged periods. These adverse hepatic effects have occurred primarily with the 17a-alkylated derivatives (e.g. methyltestosterone, Stanozolol). In men, large doses suppress spermatogenesis and cause testicular atrophy. Epididymitis and bladder irritability can occur. Priapism is a sign of excessive dosage and may occur especially in elderly males. Gynaecomastia may occur. Androgens may cause prostatic hyperplasia and accelerate the growth of malignant neoplasms of the prostate. Continued use produces symptoms of virilism, such as hirsutism or male pattern baldness, deepening of the voice, atrophy of the breasts and endometrial tissue, oily skin, acne, and hypertrophy of the clitoris. Virilisation may not be reversible, even after stopping therapy. Large and repeated doses in early puberty may cause closure of the epiphyses and stop linear growth. Children may experience symptoms of virilisation: in boys there may be precocious sexual development with phallic enlargement and increased frequency of erection, and in girls, clitoral enlargement. Gynaecomastia may also occur in boys. Masculinisation of the external genitalia of the female fetus may occur if androgens are given during pregnancy. After transdermal application of testosterone, skin reactions may include irritation, erythema, allergic contact dermatitis, and sometimes burn-like lesions. Skin reactions are more common with patches that contain permeation enhancers. The anabolic steroids, because they generally relain some androgenic activity, share the adverse effects of the androgens described above, but their virilising effects, especially in women, are usually less. There have been reports of adverse psychiatric effects in athletes taking large doses to try and improve performance.
