The correct way to take giritinib (segatan) and recommended daily dosage

Gilitinib is an oral small molecule FLT3 inhibitor, mainly used to treat patients with FLT3 mutation-positive relapsed or refractory acute myeloid leukemia (R/R AML). As a targeted drug, giritinib inhibits leukemia cell proliferation and induces apoptosis by inhibiting the activity of FLT3 kinase and blocking abnormal signaling. Proper administration and dosage management are crucial to ensure efficacy and safety.

Giritinib is generally taken in oral form, once a day, and it is recommended to take it at a fixed time to maintain stable blood concentration. The drug can be taken on an empty stomach or with food, but some patients may choose to take it with a meal to reduce gastrointestinal discomfort. When taking the medicine, the tablet should be swallowed whole and should not be chewed or crushed to avoid affecting the absorption and efficacy of the medicine. If you miss a dose, you should take it as soon as possible on the same day. However, if it is close to the next dose time, skip the missed dose and do not take double dose.

Regarding dosing recommendations, the standard starting dose for adult patients is generally 120 mg once daily. In clinical application, based on the patient's tolerance, liver and kidney function, and concomitant medications, doctors may adjust the dose to range from 80 mg to 200 mg per day. If serious adverse reactions occur during treatment, such as a significant decrease in platelets or white blood cells, abnormal liver function, or prolongation of the QT interval, the drug must be temporarily discontinued or the dosage appropriately reduced under the guidance of a doctor to ensure drug safety.

During giritinib treatment, patients should regularly review blood routine, liver and kidney function, electrocardiogram and other indicators in order to promptly detect potential side effects and intervene. At the same time, simultaneous use with potent CYP3A4 inhibitors or inducers should be avoided to avoid affecting the drug's plasma concentration and efficacy. Through standardized medication and scientific management, patients can maximize the efficacy of giritinib while minimizing the risk of adverse reactions, achieving safe and effective targeted therapy.
