What is the standard dosage of capmatinib?

Capmatinib is a highly selective oral MET inhibitor approved for the treatment of adult patients with metastatic non-small cell lung cancer (NSCLC) caused by MET exon 14 skipping mutations. The dosage and mode of drug administration are key factors in ensuring efficacy and controlling toxic and side effects. Standard usage regimens are clearly stipulated in the instructions and international clinical guidelines.

The standard recommended dose of capmatinib is400 mg taken orally twice daily, usually 12 hours apart. This dose is fixed and does not adjust based on weight or age. It can be taken with food or on an empty stomach. Food will not significantly affect its pharmacokinetic properties, so patients have certain flexibility in their medication time. In order to maintain stable blood concentration and sustained inhibitory effect, it is recommended to take it twice a day at the same time.

The drug is in the form of tablets. It is recommended to swallow the tablets whole and not to be broken, crushed or chewed to ensure the complete release of the drug effect. If you miss a dose and it is far away from the next dose, you can take it as soon as possible; if it is close to the next dose, it is recommended to skip the missed dose and continue taking the medicine normally. Do not double the dose due to missed doses.

Liver function, blood tests, and pulmonary symptoms should be regularly tested during treatment, because capmatinib may cause side effects such as elevated liver enzymes, interstitial lung disease, or photosensitivity reactions. If unacceptable toxicity occurs, the doctor may adjust the dose to 200 mg twice daily based on the patient's tolerance, or suspend the medication if necessary.

In general, the standard dosage of capmatinib is based on the balance between its inhibitory efficacy and safety window on theMET pathway. Patients must strictly follow medical instructions during use to ensure continuity of treatment and maximum efficacy.
