Mitotane

Chemical compound

Mitotane, sold under the brand name Lysodren, is a steroidogenesis inhibitor and cytostatic antineoplastic medication which is used in the treatment of adrenocortical carcinoma and Cushing's syndrome.[3][4][5][6] It is a derivative of the early insecticide DDT and an isomer of p,p'-DDDTooltip dichlorodiphenyldichloroethane (4,4'-dichlorodiphenyldichloroethane) and is also known as 2,4'-(dichlorodiphenyl)-2,2-dichloroethane (o,p'-DDD).[7]

Medical uses

Mitotane has been produced by Bristol Myers Squibb but it is marketed as an orphan drug for adrenocortical carcinoma due to the small number of patients in need of it. Its main use is in those patients who have persistent disease despite surgical resection, those who are not surgical candidates, or those who have metastatic disease. In a 2007 retrospective study of 177 patients from 1985 to 2005 showed a significant increase in the recurrence-free interval after radical surgery followed by mitotane when compared to surgery alone.[8] The drug is also sometimes used in the treatment of Cushing's syndrome.[5]

Side effects

The use of mitotane is unfortunately limited by side effects,[9] which, as reported by Schteinberg et al., include anorexia and nausea (88%), diarrhea (38%), vomiting (23%), decreased memory and ability to concentrate (50%), rash (23%), gynecomastia (50%), arthralgia (19%), and leukopenia (7%).[10]

Pharmacology

Pharmacodynamics

Mitotane is an inhibitor of the adrenal cortex. It acts as an inhibitor of cholesterol side-chain cleavage enzyme (P450scc, CYP11A1), and also of 11β-hydroxylase (CYP11B1), 18-hydroxylase (aldosterone synthase, CYP11B2), and 3β-hydroxysteroid dehydrogenase (3β-HSD) to a lesser extent.[3][9] In addition, mitotane has direct and selective cytotoxic effects on the adrenal cortex, via an unknown mechanism, and thereby induces permanent adrenal atrophy similarly to DDD.[11][12]

Chemistry

Analogues of mitotane include aminoglutethimide, amphenone B, and metyrapone.

History

Mitotane was introduced in 1960 for the treatment of adrenocortical carcinoma.[5]

Society and culture

Generic names

Mitotane is the generic name of the medication and its INNTooltip International Nonproprietary Name, USANTooltip United States Adopted Name, BANTooltip British Approved Name, and JANTooltip Japanese Accepted Name.[6][13]

Brand names

Mitotane is sold under the brand name Lysodren.[6]

Veterinary use

Mitotane is also used to treat Cushing's disease (pituitary-dependent Cushing's syndrome) in dogs. The medication is used in the controlled destruction of adrenal tissue, leading to a decrease in cortisol production.[14]
