What are the side effects or side effects of lorlatinib/lorlatinib?

Lorlatinib/lorlatinib (Lorlatinib) is a targeted drug mainly used to treat adult patients with ALK-positive advanced non-small cell lung cancer (NSCLC). Indications for these patients include treatment-naive patients who have not received ALK therapy and patients whose disease has progressed after receiving alectinib, ceritinib, or crizotinib and at least one other ALK inhibitor. Lorlatinib has become an important treatment option for these patients due to its good efficacy and tolerability.

Although the use of lorlatinib can improve patient survival rates, it is also associated with some side effects. Of these, the most common side effects include hypercholesterolemia and hypertriglyceridemia, both of which involve dyslipidemia and are due to the drug's effect on lipid metabolism. In addition, edema is a common side effect, which is an abnormal accumulation of fluid in certain parts of the body and can cause discomfort to the patient. Peripheral neuropathy causes nerve damage in the hands and feet, and patients may experience symptoms such as numbness, tingling, or pain.

Weight gain, cognitive effects, fatigue, etc. are also common problems with lorlatinib treatment. Cognitive effects may involve problems with thinking, learning, and memory, which may affect patients' daily life and work. Fatigue is a common challenge faced by cancer patients, and the use of lorlatinib may aggravate this symptom. Other side effects such as difficulty breathing, joint pain, diarrhea, and cough also require the attention of doctors and patients.

It is important to note that some side effects of lorlatinib may be serious. Among them, problems with cognitive function can have a significant impact on a patient's quality of life, while pneumonia is a serious complication that can lead to hospitalization or even be life-threatening. Therefore, physicians need to monitor patients closely during treatment with lorlatinib to identify and manage these side effects in a timely manner.
