• Description: Erlotinib is a tyrosine kinase inhibitor which acts on the epidermal growth factor receptor (EGFR), inhibiting EGFR-associated kinase activity (IC50 = 2.5 μM). This inhibits tumor growth in human head and neck carcinoma HN5 tumor xenografts in mice with an ED50 value of 9 mg/kg. Erlotinib also suppresses cyclin-dependent kinase 2 (Cdk2) activity in breast cancer cells (IC50 = 4.6 μM) and JAK2 mutant JAK2V617F positive hematopoietic progenitor cells (IC50 = 5 μM), which is associated with polycythemia vera, idiopathic myelofibrosis, and essential thrombocythemia. Formulations containing erlotinib have been used to treat certain forms of cancer, including non-small cell lung cancer.
• Uses: antineoplastic;tyrosine kinase inhibitor A tyrosine kinase inhibitor
• Clinical Use: ErlotinibTreatment of locally advanced or metastatic nonsmall cell lung cancer after failure of at least 1 other regimePancreatic cancer
• Drug interactions: Potentially hazardous interactions with other drugs Analgesics: increased risk of bleeding with NSAIDs.Antacids: concentration possibly reduced by antacids, give at least 4 hours before or 2 hours after erlotinib. Anticoagulants: increased risk of bleeding with coumarinsAntipsychotics: avoid concomitant use with clozapine, increased risk of agranulocytosis.Antivirals: avoid with boceprevir.Ulcer-healing drugs: avoid with cimetidine, esomeprazole, famotidine, lansoprazole, nizatidine, pantoprazole and rabeprazole; concentration reduced by ranitidine, give at least 2 hours before or 10 hours after ranitidine; concentration reduced by omeprazole - avoid.
