Hirsutism drug-induced

Toxicities are numerous and include nephrotoxicity, hypertension, hyperglycemia, liver dysfunction, hyperkalemia, altered mental status, seizures, and hirsutism. Cyclosporine causes very little bone marrow toxicity. While an increased incidence of lymphoma and other cancers (Kaposi s sarcoma, skin cancer) have been observed in transplant recipients receiving cyclosporine, other immunosuppressive agents may also predispose recipients to cancer. Some evidence suggests that tumors may arise after cyclosporine treatment because the drug induces TGF-B, which promotes tumor invasion and metastasis. 

Normal sexual activity is associated with ovulation in most female mammals. Compounds affecting this process can adversely affect female libido. Ovarian failure induced by xenobiotic compounds has been associated with a decrease in libido in women. Certain types of oral contraceptives as well as drugs of abuse (methadone, cannabis, alcohol) cause decreases in female libido. The treatment for hirsutism, excessive growth of hair in both normal and abnormal locations, is the compound cyproterone acetate. It is an antiandrogen that has the side effect of severely decreasing libido in women. 

Direct vasodilators frequently produce baroreflex-induced tachycardia, but rarely orthostatic hypotension. They are usually prescribed with a beta blocker or a centrally acting antihypertensive to minimize the reflex increase in heart rate and cardiac output. It should be noted that another member of the directly acting class of antihypertensives is minoxidil. This potent, long-acting drug has gained considerable notoriety for its use as a topical hair-restorer. Oral use can result in hirsutism (unwanted hair growth over the face as well as other parts of the body). 

Co-cyprindiol is a mixture of the anti-androgenic progestogen, cyproter-one acetate 2 mg, with ethinylestradiol 35 micrograms. It is used for the treatment of acne and moderately severe hirsutism in women who may also wish to use it as an oral contraceptive, and its contraceptive efficacy is expected to be reduced by the same hepatic enzyme inducers (see Table 28. r, (p.975)) that interact with conventional combined oral contraceptives. The precautions described in this section for the combined hormonal contraceptives with the various drugs listed in Table 28.1 , (p.975), should therefore be followed, see Hormonal contraceptives + Antiepileptics Barbiturates or Phenytoin , p.985.
