►  Side Effect : increased retention of sodium and water, oedema, hypercalcaemia, and impaired glucose tolerance., increased lowdensity- lipoprotein cholesterol, decreased high-density- lipoprotein cholesterol, increased haematocrit, and suppression of clotting factors., headache, Depression, gastrointestinal bleeding, jaundice, cholestatic hepatitis, peliosis hepatis and hepatic tumours in patients who have received high doses over prolonged periods., 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, In women, the inhibitory action of androgens on the activity of the anterior pituitary results in the suppression of ovarian activity and menstruation. 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.,

►  Drug Interaction : Drug interaction of Testosterone is with ,  Levothyroxine, Warfarin ,
Ref :-   Book : Martindale    Page : 2339   Edition : 37,

  ►    Mechanism of Drug Drug Interaction :  Testosterone and other androgens and anabolic steroids have been reported to enhance the activity of a number of drugs, with resulting increases in toxicity. Drugs affected include ciclosporin, levothyroxine, and anticoagulants such as warfarin. Resistance to the effects of neuromuscular blockers has also been reported. As androgens and anabolic steroids can alter glucose metabolism, doses of insulin or oral antidiabetics may need adjustment.,

►  Contraindication : Testosterone and other androgens and anabolic steroids should be used cautiously in patients with cardiovascular disorders, renal or hepatic impairment, epilepsy, migraine, diabetes mellitus or other conditions that may be aggravated by the possible fluid retention or oedema caused., They should not be given to patients with hypercalcaemia or hypercalciuria, and should be used cautiously in conditions in which there is a risk of these developing such as skeletal metastases., The use of the 17α-alkylated derivatives, which are associated with an increased risk of hepatotoxicity, is probably best avoided in patients with hepatic impairment, and certainly if this is severe. Hepatic function should be monitored during therapy., In men, androgens and anabolic steroids should not be given to those with carcinoma of the breast or prostate (although in women they have been used in the treatment of certain breast carcinomas., The prostate should be examined regularly during treatment., Androgens and anabolic steroids should be used with extreme care in children because of the masculinising effects and also because premature closure of the epiphyses may occur resulting in inhibited linear growth and small stature. Skeletal maturation should be monitored during therapy., Patients using testosterone gels should take care to wash their hands after every application, and to cover the site with clothing once the gel has dried. The area should also be washed thoroughly before skin-to-skin contact with another person. Inappropriate virilisation, advanced bone age, increased libido, and aggressive behavior have been repor,

  ►  Mechanism of Action :   testosterone acts intracellularly in target cells. In skin, prostate, seminal vesicles, and epididymis, it is converted to 5α-dihydrotestosterone by 5α-reductase. In these tissue dihydrotestosterone is the dominant androgen.Testosterone and dihydrotestosterone bind to the intracellular androgen receptor, initiating a series of events similar to those described above for estradiol and progesterone, leading to growth, differentiation, and synthesis of a variety of enzymes and other functional proteins.,
