Mitotane works primarily by inhibiting the function of adrenal cortical cells. It can inhibit cholesterol side-chain lyase, a key enzyme in steroid hormone synthesis, thereby reducing the synthesis of steroid hormones such as cortisol.
The use of Mitotane mainly includes oral administration, and the specific use method and dose need to be determined according to the specific situation of the patient and the guidance of the doctor.
Adults may start with a low dose of Mitotane, which is then titrated according to the patient's response and tolerability until the maximum tolerated dose is reached.
It is generally recommended that the daily dose should not exceed 18 mg and should be taken in divided doses.
In children, the efficacy and safety of Mitotane are not fully established, and the dose should be determined by the physician based on the patient's weight or body surface area.
Adrenocortical carcinoma causes abnormal levels of sex hormones, and its clinical manifestations mainly include:
Women may present with significant virilizing features such as hirsutism, acne, thickened voice, breast atrophy, menstrual disturbances, or amenorrhea due to excessive androgen secretion by the tumor.
Although male patients are less likely to be directly feminized, signs of androgenism such as abnormal body hair and changes in sexual organs may be present.
In addition to the above-mentioned changes in sex characteristics, abnormal levels of sex hormones may also cause systemic metabolic disorders, such as osteoporosis, muscle weakness, and weight loss, which may be related to changes in overall physiological function caused by abnormal hormone levels.
The clinical manifestations of adrenocortical carcinoma are complex and diverse, and the early symptoms may not be obvious, once the symptoms appear, it is necessary to seek medical attention in time and perform relevant examinations to confirm the diagnosis.
For abnormal sex hormone levels caused by adrenocortical carcinoma, the main countermeasures include:
Adrenocortical carcinoma is the root cause of abnormal sex hormone levels, and the first priority is to perform surgical treatment, such as adrenalectomy, to remove the source of the tumor and fundamentally solve the problem of abnormal sex hormone secretion.
Hormone replacement therapy may be needed before and after surgery, or if surgery is not possible, to maintain stable hormone levels in the patient's body and relieve symptoms caused by abnormal sex hormone levels.
During treatment, the patient's sex hormone level and physical condition should be closely monitored, and the treatment plan should be adjusted in time to ensure the treatment effect.
【Warm tips】When patients buy generic drugs, they should choose formal channels to ensure the quality and safety of the drugs. Avoid purchasing counterfeit products from informal sources.
