Uses of Mitotane

Mitotane is used to treat adrenal cortical carcinoma (non-surgical) and Cushing’s syndrome.

Mechanism of action

  • Adrenolytic agent.
  • Dysfunction of the adrenal cortex, adrenal atrophy of the shingles and shingles of the shingles and eventually tumor death (via binding to mitochondrial proteins).
  • Direct inhibition of the adrenal cortex and changes in the peripheral metabolism of steroids.

Reducing the effects of Mitotane by drugs


Enhanced effects of drugs by Mitotane:

Clarithromycin, Doxercalciferol, Ifosfamide, Lorlatinib, Tiotapa

Increased effects of Mitotane by drugs:



  1. Therapeutic drug concentrations should be monitored every 4-8 weeks until reaching the target concentration and then every 3 months (using gas chromatography-flame ionization
  2. At the beginning of treatment of children (with adrenocortical cancer), the serum concentration of the drug should be monitored every 2-4 weeks until reaching a concentration of 10 micrograms / ml and then every 1-2 weeks (even after reaching the target concentration of 14-20 micrograms / ml Liters). Dose adjustment should be made according to the narrow treatment window and drug accumulation.
  3. Adrenal function, free cortisol levels, adrenocorticotropin (ACTH), TSH and free thyroxine are monitored periodically during treatment.
  4. The patient should be monitored for central nervous system toxicity (confusion, depression, extreme fatigue, changes in speech and balance), adrenal crisis and ovarian macrocysts (vaginal bleeding and / or pelvic pain) and the patient should be warned to report these symptoms. Report speed.
  5. Behavioral and neurological examinations are recommended.
  6. It is necessary to check other medications used by the patient to adjust the dose if necessary or to use alternative therapy.
  7. The patient should be reminded of the need for regular medication and completion of treatment.

Mitotane drug recommendations

  1. Initial treatment should be performed in a hospital until the dose is stabilized.
  2. The dose should be adjusted according to the maximum tolerable dose for each patient and based on the presence of side effects and improvement of clinical responses.
  3. Treatment with glucocorticoids may also be necessary in patients treated with mitotane, especially in long-term treatment. After stopping treatment with mitotane, steroid treatment should be continued until the adrenal cortex returns to normal.
  4. Continuous treatment with the maximum tolerable amount of mitotane seems to be more effective than intermittent treatment.
  5. The duration of treatment also depends on the clinical response. Only 15% of patients who have been treated with the maximum tolerable dose for three months but have not responded to treatment show a clinical response by continuing treatment.
  6. It is recommended that in the event of shock or severe trauma, treatment with mitotane be discontinued immediately and temporarily, and that steroids be given, as decreased adrenal function may impair the natural response to these stresses.
