Analysis of the Reports of Adverse Dug Reaction Induced by EGFR-TKI in Shandong Province / 中国药房

ABSTRACT

OBJECTIVE：To analyze the clinical manifestations and characteristics of adverse drug reactions （ADR）induced by EGFR-TKI，and to provide reference for safe use of drugs in clinic. METHODS ：The relevant data of EGFR-TKI-induced ADR reports which were reported to Shandong ADR Monitoring Center from January 2018 to December 2020 were summarized ，and analyzed statistically in respects of age ，gender，drug variety ，ADR classification ，usage and dosage ，occurrence time ，involved organs/systems，clinical manifestations and prognosis of patients. RESULTS & CONCLUSIONS ：A total of 120 ADR reports induced by EGFR-TKI were included ，involving 120 patients. Among 120 patients，the female （60.83％）was more than the male （39.17％），and the age was mainly 50-79 years old （79.16％）. A total of 5 drugs including gefitinib ，ositinib，afatinib，ektinib and erlotinib were involved. ADR occurred in 72，11，15，6 and 16 patients using the above drugs respectively ；the main ADR was general ADR （70.83％），followed by severe ADR （22.50％），new general ADR （5.00％）and new severe ADR （1.67％）. All patients were given drugs orally ，off-label use was found in 2 patients who used ektinib ，and the rest met the medication requirements of the drug instructions. ADR occurred in 61 patients（50.83％）within 1 month after medication ，34 patients （28.33％）within 1-3 months after medication ，25 patients（20.83％）within 4-12 months after medication ，and no ADR occurred after 12 months. ADR of organs/systems involved were mainly the lesion of skin and its appendant injury，gastrointestinal system injury and hepatobiliary system injury. The main clinical manifestations were rash ，diarrhea and abnormal liver function ；in addition，some patients developed severe or new severe ADR such as interstitial pneumonia ，bone marrow suppression ，tongue swelling and cerebral infarction. Totally 102 patients recovered or improved after drug withdrawal or symptomatic treatment ，12 patients had unknown outcome ，and 6 patients did not improve. It is suggested that pharmaceutical care should be strengthened within 1 month after EGFR-TKI administration ，so as to guard against the occurrence of new and serve ADR and ensure the safety of clinical medication.
