Which drugs interact with Pemigatinib

The core mechanism of Pemigatinib, a class of small molecule kinase blockers specifically targeting FGFR1, FGFR2, and FGFR3 receptors, lies in the effective inhibition of phosphorylation activity on these receptors and the subsequent development of complex signaling pathways.

Which drugs interact with Pemigatinib

Pemigatinib is a targeted drug that may interact with a variety of drugs during treatment.

1. Inhibitor of CYP3A4 enzyme

Some drugs, such as crizotinib and ketoconazole, may inhibit the activity of the CYP3A4 enzyme, resulting in a slowdown in the metabolism of Pemigatinib in the body and an increase in blood concentration, thereby increasing the risk of toxic side effects.

2. Inducers of the CYP3A4 enzyme

Some drugs, such as ribavirin and erythromycin, may induce the activity of the CYP3A4 enzyme, accelerate the metabolism of Pemigatinib, reduce its blood concentration, and affect the therapeutic effect.

How to deal with drug interactions

Measures to deal with drug interactions mainly include the following:

1. Reduce the number of drugs combined

In the case of guaranteed efficacy, the number of drugs used in combination should be minimized to reduce the risk of drug interactions.

2. Use drug interaction warning systems

Physicians should make full use of computerized drug interaction warning systems, which can assist physicians in reviewing patients' drug regimens and predicting and preventing adverse drug interactions and adverse reactions.

Precautions for the use of Pemigatinib

When using Pemigatinib, patients and their families need to pay attention to the following aspects to ensure safe and effective treatment.

1. Have regular eye exams

Although OCT is not routinely performed in clinical trials to detect asymptomatic RPED, patients should still have regular eye examinations, especially those with a history of ocular disease or high-risk factors. This helps to detect and treat any potential eye problems early.

2. Pay attention to liver function monitoring

Pemigatinib may have an effect on liver function, so regular monitoring of liver function parameters is required during use. If a person's liver function is abnormal, doctors may need to adjust the dose or take other measures.

【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.
