Literature analysis of ADR after the listing of apatinib / 中国药房

ABSTRACT

OBJECTIVE To explore the characteristics and regulations of adverse drug reactions （ADR） caused by apatinib， and to provide a reference for the safe use of apatinib in clinic. METHODS Case and group reports on ADR and safety evaluation of apatinib were retrieved from Chinese and English databases such as CNKI， Wanfang medical network， VIP and PubMed since its listing in 2014， literature data were extracted and statistically analyzed after screening. RESULTS Totally 101 cases were included， involving 221 ADR. In the above cases， the male-to-female ratio was 1.24∶1， with the highest proportion of patients aged 51 to 70 years， most of the patients were given a dose of 500 mg or more， and the patients given low dose of apatinib combined with other antitumor drugs were also likely to have ADR. One to two types of adverse reaction were the most common， while the types could reach up to six. Most ADR occurred within 30 days after medication， and the systems/organs involved were mainly the cardiovascular system damage，skin and its accessories damage， gastrointestinal system damage and urinary system damage； the main clinical manifestations were hypertension/aggravation，hand-foot syndrome，abdominal pain diarrhea and albuminuria， etc. Hypertension/aggravation， hand-foot syndrome and myelosuppression were the most common serious ADR. Most ADR could be improved/cured by suspension of administration， dose downregulation and symptomatic treatment. All 4 patients who died had underlying diseases， and their ECOG scores all ≥2 points. Special ADR （such as reversible posterior encephalopathy syndrome， psychiatric disorders， and cognitive impairment） were mostly caused by apatinib itself， or may be caused by apatinib in combination with the primary or underlying disease. CONCLUSIONS Advanced age， large dose， combination medication， underlying diseases and poor physical condition might be the high risks for ADR caused by apatinib. It is recommended to monitor the blood pressure，urine protein and skin of hands and feet of all patients with medication on a daily basis，pay attention to the occurrence of special ADR， and timely detect abnormal states and give effective intervention，so as to avoid the aggravation of ADR and other secondary ADR.
