What is Lazertinib Mesilate Monohydrate?
Lazertinib, the active ingredient in Lazcluze, is a tyrosine kinase inhibitor presented as a unknown/unknown for oral use. It treats non‑small cell lung cancer that carries epidermal growth factor receptor (EGFR) mutations in adult patients.
GNH USA supplies Lazcluze as a licensed, GDP‑compliant international pharmaceutical supplier serving oncology centres worldwide.
What is Lazertinib Mesilate Monohydrate used for?
Lazcluze is a targeted therapy that acts on EGFR‑mutated non‑small cell lung cancer.
Non‑small cell lung cancer with EGFR mutations: improves progression‑free survival and tumor response in patients whose tumours harbor activating EGFR alterations.
What are the side effects of Lazertinib Mesilate Monohydrate?
Adverse reactions may vary in frequency and severity.
Common Side Effects: - Diarrhea: mild to moderate gastrointestinal upset. - Skin rash: papulopustular eruption, often on the face or trunk. - Nausea: occasional feeling of queasiness. - Decreased appetite: reduced food intake. - Fatigue: general tiredness. - Elevated liver enzymes: transient increase in ALT/AST.
Serious or Rare Side Effects: - Interstitial lung disease: new or worsening respiratory symptoms. - Severe hepatic injury: marked elevation of liver enzymes or jaundice. - QT interval prolongation: potential cardiac arrhythmia risk. - Stevens‑Johnson syndrome: severe skin and mucosal reactions. - Grade 3/4 neutropenia: significant reduction in white blood cells. - Hepatotoxicity: liver failure requiring medical intervention.
What precautions apply to Lazertinib Mesilate Monohydrate?
Patients should be monitored for specific safety concerns before and during treatment.
Liver function monitoring: assess ALT, AST, and bilirubin regularly. Cardiac assessment: obtain baseline ECG and monitor QT interval. Pulmonary evaluation: watch for signs of interstitial lung disease. Avoid use in severe hepatic impairment: contraindicated in patients with Child‑Pugh C. Drug interaction awareness: review concomitant medications that affect CYP3A4. Store at below 25°C: keep in original container, protect from moisture and light.
What does Lazertinib Mesilate Monohydrate interact with?
Lazcluze may interact with other medicines that influence its metabolism or cardiac safety.
Major Interactions (Avoid): - Strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole): may increase plasma concentrations. - Strong CYP3A4 inducers (e.g., rifampin, carbamazepine): may reduce efficacy. - QT‑prolonging agents (e.g., certain antiarrhythmics): additive risk of arrhythmia.
Moderate Interactions (Monitor Closely):\n- Antacids containing aluminum or magnesium: may affect absorption, separate dosing by at least 2 hours. - Moderate CYP3A4 inhibitors (e.g., erythromycin): may modestly raise drug levels. - Warfarin: monitor INR as EGFR inhibitors can alter coagulation parameters.
