Clinical pharmacists participated in the liver protection treatment process of a patient with advanced renal cell carcinoma with severe liver injury. By analyzing the patient's previous med-ication history, combined with laboratory examination, the possibility of severe liver dysfunction caused by pezopanib tablets was evaluated by using Naranjo's adverse drug reaction probability scale. Through consulting the literature and combined with the characteristics of patients' laboratory ex-amination, the possible mechanism of liver injury caused by pezopanib tablets was analyzed. It was suggested that the clinical drug should be stopped in time and individualized liver protection treat-ment should be carried out. Finally, the patient's liver injury was significantly improved. In this case, the clinical pharmacist combined pharmaceutical knowledge and clinical practice to provide effective pharmaceutical suggestions for the clinic, which fully reflects the value of the clinical pharmacist and provides a certain reference for the severe liver injury caused by pezopanib tablets in the future.
