How many years of Zongatinib (Zongatinib) is generally taken and the safety of long-term use

Zongertinib is an oral targeted drug mainly used to treat patients with advanced non-small cell lung cancer who have specific gene mutations (such as ROS1 or RET). Regarding the length of time for taking the drug, there is no uniform fixed number of years in clinical practice. It is usually determined based on the patient's tolerance to the drug, efficacy and disease progression. Generally speaking, as long as the patient tolerates the medication and the disease does not progress significantly, doctors will recommend continued medication to maintain tumor control.

When using zongatinib for a long time, safety is a key concern for patients and doctors. Clinical studies have shown that common adverse reactions of this drug include mild to moderate nausea, fatigue, diarrhea, hematological abnormalities, and increased liver function indicators. Most side effects can be controlled through drug dose adjustment, supportive treatment, or intermittent medication, but hematological indicators, liver and kidney functions, and electrocardiograms still need to be regularly monitored to reduce potential risks.

For patients who require long-term use, drug tolerance is a critical factor. Some patients may experience decreased dose compliance, accumulation of minor side effects, or rare serious events during long-term use, such as cardiac QT interval prolongation or liver damage. Therefore, during long-term treatment, doctors usually adjust the dose or arrange intermittent review based on the patient's clinical condition to balance efficacy and safety.

In addition, long-term medication also requires attention to drug interactions. Zongertinib is mainly metabolized by the liver. If CYP3A inhibitors or inducers are used at the same time, the plasma concentration may be affected, thereby affecting the efficacy or increasing the risk of toxicity. Therefore, patients must inform their doctor when taking other medications or supplements and have them reviewed regularly to ensure the safety and effectiveness of long-term medication.
