Mitotane: Drug Types and Uses

Mitotane is an anti-tumor drug, specifically classified as a chemotherapy drug. It was originally discovered as a derivative of the pesticide DDT and was further studied and developed for its potential effectiveness in treating adrenocortical cancer. The chemical name of mitotane is chlorobenzene dichloroethane. Its structure is similar to the insecticides DDT and DDD, but it has unique pharmacological effects.

Mitotan is an important part of the treatment of adrenocortical carcinoma (ACC), especially for patients with inoperable or postoperative local recurrence and metastasis. It mainly slows down tumor growth by inhibiting the function of adrenocortical cells and reducing the production of steroid hormones such as cortisol, aldosterone and androgens. Mitotane can block key enzymes in the synthesis of adrenocortical hormones, such as 17α-hydroxylase, thereby inhibiting the synthesis of cortisol and androgens.

Mitotane is also used to treat certain types of adrenal hyperplasia. In adrenocortical hyperplasia, the cells of the adrenal cortex grow abnormally, which may lead to excessive secretion of hormones. Mitotane relieves symptoms by inhibiting the function of adrenocortical cells and reducing hormone production.

Mitotane is also used to treat hypercortisolism caused by tumors (Cushing's syndrome). Hypercortisolism is a disease caused by excessive secretion of cortisol from the adrenal cortex, which may lead to a series of symptoms, such as central obesity, moon face, buffalo hump, etc. Mitotane relieves symptoms by inhibiting the function of adrenocortical cells and reducing cortisol production.

Although mitotane has significant efficacy, it also has some adverse reactions, such as gastrointestinal reactions, neuromuscular toxicity, eye toxicity, genitourinary system toxicity, cardiovascular toxicity, etc. In addition, mitotane may cause damage to the liver and kidneys. Therefore, when using mitotane, you must strictly follow the doctor's instructions, regularly monitor the patient's physical condition and drug concentration, and promptly adjust the treatment plan and respond to adverse reactions.
