- Hepatic, cardiac, renal failure( severe),
- Pregnancy and lactation.
Used with caution in patients with heart disease, bradycardia or electrolyte imbalance.
Mechanism of action
The active substance inhibits the kinase receptors responsible for the growth of formation, the formation of malignant cells in other organs. It is an inhibitor of growth factor and stem cells.
During treatment, suppression of tumor growth occurs even with regression. Metabolite activity is similar to that of sunitinib.
When taken is well absorbed. After 6-11 hours the amount of active substance in the blood reaches the maximum markings. The intake of food does not affect the pharmacokinetics. The degree of communication with proteins reaches 95%.With repeated administration, accumulation is observed 3-4 times.
Instruction for use of the drug
Suspension The regimen depends on the characteristics of the cancer:
- Stromal gastrointestinal tumors - the recommended dose is 50 mg per day for a total of 4 weeks. Then a break for 14 days.
- The renal cell carcinoma is 50 mg per day for a month.
- Inoperable or metastatic neuroendocrine tumors of people with disease progression - 37.5 mg daily without interruptions.
If the reception was missed, do not take capsules further.
Depending on the tolerability, the dose can be adjusted to 12.5 mg more or less. Older patients are not subject to dose changes.
Side effects of
Undesirable effects depend on the general condition of the body and the characteristics of the disease. The most serious side effects are:
- pulmonary embolism,
- tumor bleeding,
- febrile neutropenia,
- arterial hypertension.
With venous thrombosis patients, venous thromboembolism was observed in patients.
There is no specific antidote. Therefore, a symptomatic treatment is prescribed, which consists of rinsing the stomach and inducing vomiting reactions.
Before starting therapy, it is necessary to conduct a study of hematological parameters.
There have been reports of bleeding events leading to death. These manifestations are unexpected. Therefore, it is necessary to periodically inspect and assess blood counts.
In anticoagulant therapy, blood coagulability is monitored.
Thyroid gland studies are conducted in people with hypo- hyperthyroidism. Treatment is carried out in accordance with medical practice before treatment.
The use of the Sutene together with inhibitors of the isoenzyme CYP3A4 leads to an increase in the concentration of the active component in the blood. With the simultaneous use of this antitumor drug with cathonazole, the active metabolite content may increase.
Therefore, it is recommended not to allow the simultaneous administration of the Sutent with inhibitors of CYP3A4, choosing an alternative treatment regimen. If this is not possible, the daily dose should be reduced by 12.5 mg, but not less than 37.5 mg.
For many patients, the use of the drug is difficult due to its high cost. Moscow is the only city where you can get the medicine for free. But only a small number of cancer patients can count on this.
