Ensartinib is a targeted therapy for ALK-positive non-small cell lung cancer (NSCLC). Common adverse reactions include gastrointestinal symptoms, abnormal liver function and skin rashes. In severe cases, interstitial lung disease or cardiotoxicity may occur. Patients must take the medication as prescribed and undergo regular monitoring.
Common Adverse Reactions
Gastrointestinal reactions
Symptoms such as nausea, vomiting, diarrhea and decreased appetite can be alleviated by dietary adjustments or medication.
Skin reactions
Manifestations including rashes, pruritus and xerosis cutis. Mild symptoms can be managed with topical medication for care, while medical attention is required for severe cases.
Systemic symptoms
Fatigue, edema and myalgia or arthralgia are usually mild to moderate in severity.
Abnormal liver function
Elevated transaminases are relatively common. Regular liver function monitoring is necessary, and dose adjustment may be required if needed.
Severe Adverse Reactions (Requiring Immediate Medical Attention)
Interstitial lung disease/pneumonitis
Characterized by dyspnea, worsening cough or fever. Immediate drug withdrawal and medical consultation are mandatory.
Cardiotoxicity
May present as bradycardia or QT interval prolongation, necessitating regular electrocardiogram (ECG) monitoring.
Hyperglycemia
Some patients may experience elevated blood glucose levels, especially diabetic patients who need close blood glucose monitoring.
Other Potential Reactions
Ophthalmic disorders
Symptoms like blurred vision and photopsia may be associated with retinopathy.
Hematological abnormalities
Conditions such as anemia and neutropenia require regular blood routine tests.
Precautions and Medication Guidelines
Strictly follow the doctor’s instructions: Dose adjustment or drug withdrawal must be determined by the physician based on individual patient conditions.
Monitoring and follow-up
During treatment, patients need to undergo regular examinations of liver function, electrocardiogram, blood glucose and blood routine.
Lifestyle recommendations
Avoid strong sunlight exposure (to prevent skin rashes), maintain a balanced diet and engage in moderate physical activity.
If patients experience persistent vomiting, severe dyspnea, chest pain, jaundice or confusion, they should immediately stop taking the medication and contact their doctor. Targeted therapy requires individualized regimens, and patients must not adjust the medication on their own.
