What is the correct dosage for using mobosetinib/mobosetinib

The recommended standard dose of Mobocertinib for the treatment of non-small cell lung cancer (NSCLC) is 160 mg orally per day, usually taken once on an empty stomach. Patients should take the drug at a fixed time every day to keep the drug concentration stable to exert a sustained inhibitory effect. This dose was determined based on a comprehensive evaluation of efficacy and tolerability in patients with EGFR exon 20 insertion mutation-positive advanced non-small cell lung cancer in clinical trials.

During the medication period, patients should be careful not to take it with potent CYP3A4 inhibitors or inducers at the same time, so as not to affect the metabolism and blood concentration of moboxetinib. If combined use is necessary, a professional physician should adjust the dose or monitor blood drug concentrations based on drug metabolism interactions to avoid increased toxicity or weakened efficacy. In addition, patients should avoid eating foods containing CYP3A4 activity such as grapefruit, which may significantly interfere with the drug metabolism process.

If intolerable adverse reactions occur, such as severe diarrhea, QT interval prolongation, rash or abnormal liver function, dosage adjustment should be considered under the guidance of a doctor. According to international treatment guidelines, the reduction step is usually from 160 mg to 120 mg, and if still intolerable, then to 80 mg. When serious adverse reactions cannot be controlled, the drug may need to be temporarily discontinued or permanently discontinued. Therefore, patients should undergo regular monitoring of liver function, electrolytes, electrocardiogram and blood images to determine whether the treatment plan needs to be adjusted.

It is worth noting that if you miss a dose during the medication, you should take it within 12 hours. It is not recommended to take it after 12 hours, but you should wait for the next dose directly to avoid the risk of toxicity caused by excessive dosage. In addition, medicines should be stored in a dry and cool place away from direct sunlight, and medications should not be stopped or the dosage changed on your own.
