Guidelines for the management of side effects of the lung cancer targeted drug brigatinib

Brigatinib (Brigatinib), as a targeted therapy for anaplastic lymphoma kinase (ALK)-positive non-small cell lung cancer (NSCLC), brings new treatment hope to patients. However, along with its efficacy, there may also be a series of side effects. To help patients better cope with these challenges, below are detailed management guidelines for common side effects, signs of allergic reactions, and serious hazards of brigatinib.

1. Common side effects and management strategies

1. Digestive system reactions: Nausea, vomiting and diarrhea are common digestive system discomforts during brigatinib treatment. It is recommended that patients adjust their diet, choose light and easy-to-digest foods, and eat small amounts with frequent meals. If symptoms persist or worsen, you should consult your doctor promptly and consider using anti-nausea drugs or antidiarrheal drugs for symptomatic treatment.

2. Increased blood pressure: Blood pressure changes need to be closely monitored during treatment, especially for patients with a history of hypertension before treatment. If symptoms related to high blood pressure such as severe headache, severe pain in the neck or ears occur, you should seek medical attention immediately and use antihypertensive drugs for intervention under the guidance of a doctor.

3. Respiratory symptoms: Although difficulty breathing is rare, seek medical attention immediately if it occurs. Coughing may be a lung irritation reaction caused by drugs. If symptoms persist or worsen, you should also inform your doctor in time.

4. Skin reaction: Mild rashes can be relieved by topical ointment; if the rash is severe or accompanied by other symptoms, you may need to discontinue the medication and seek professional medical advice.

5. Muscle pain and headache: These symptoms are usually mild and can be relieved by rest, massage and other non-drug treatments. If symptoms persist or worsen, you should communicate with your doctor promptly.

6. Fatigue: Brigatinib may cause patients to feel tired. It is recommended that patients take adequate rest and take appropriate nutritional supplements to improve fatigue.

2. Signs and emergency treatment of allergic reactions

While taking brigatinib, if patients develop signs of an allergic reaction such as hives, difficulty breathing, swelling of the face, lips, tongue, or throat, they should seek medical attention immediately and inform their doctor. These may be severe allergic reactions requiring urgent medical intervention.

3. Monitoring and response to serious hazards

1. Lung problems: Symptoms such as cough, difficulty breathing, chest pain, and fever may be signs of interstitial lung disease (ILD) or pneumonia. Once these symptoms occur, you should stop taking the medicine immediately and contact your doctor.

2. Vision problems: Abnormal vision symptoms such as blurred vision, double vision, increased sensitivity to light, etc. should be reported to a doctor in a timely manner and an eye examination should be conducted under the guidance of a doctor.

3. Abnormal blood sugar: For patients with diabetes or glucose intolerance, brigatinib may cause an increase in blood sugar. It is recommended to monitor blood sugar levels regularly and adjust the hypoglycemic treatment plan under the guidance of a doctor.

4. Heart problems: Bradycardia is one of the heart problems that may occur during brigatinib treatment. Patients should monitor their heart rate regularly and seek medical attention promptly if symptoms occur.

5. Muscle injury and pancreatitis: Unexplained muscle pain, weakness, and upper abdominal pain may indicate muscle injury or pancreatitis. Patients should report these symptoms promptly and conduct further examination and treatment under the guidance of a doctor.

In conclusion, although brigatinib provides an effective treatment option for patients with ALK-positive NSCLC, management of side effects is equally important. Patients should follow medical advice, regularly monitor relevant health indicators, and seek medical treatment promptly if any symptoms of discomfort occur. At the same time, understanding and following the above side effect management guidelines can help patients better cope with the challenges during treatment. There are many versions of brigatinib currently on the market. Patients should purchase it as needed, but be sure to go through formal channels and pay attention to identify the authenticity of the drug.
