          摘  要  目的  分析吉非替尼基于药动学的潜在不良药物相互作用(PK-pADIs),并建立相应审方规则。方法  通过医院合理用药管
          理系统抽取我院2022年1月1日-2024年11月30日吉非替尼联合用药的门诊处方,基于Drugs.com 药物相互作用数据库鉴别处
                                                                                      ®
          方中存在的PK-pADIs,统计具体联用药物及PK-pADIs发生例次,并根据PK-pADIs严重性分级建立审方规则。结果与结论  共收
          集到吉非替尼联合用药处方 217 张,其中 28 张处方(12.90%)、共计 28 例患者存在 PK-pADIs 29 例次,以呼吸内科处方(22 张)为
          主;联用药物包括质子泵抑制剂(13例次)、细胞色素P450 3A4(CYP3A4)强抑制剂(7例次)、H2受体拮抗剂(4例次)、CYP3A4诱
          导剂(3例次)、CYP2D6底物(2例次),严重性分级分别为严重、中度、严重、中度、中度。根据上述PK-pADIs严重性分级,建立审方
          规则4项,即吉非替尼与抑酸药物联合使用,予“人工审核”处理;吉非替尼与地塞米松、美托洛尔和CYP3A4强抑制剂联用,予“提
          醒”处理,并通过提醒框告知医生加强相关指标监测。临床药师需深入呼吸内科等重点临床科室加强有关吉非替尼药物相互作用
          知识的培训,加强针对长期使用吉非替尼患者的合理用药监测与指导,及时发现并干预PK-pADIs,提高临床用药的合理性、安全
          性和有效性。

          Prescription  investigation  for  potential  adverse  drug  interactions  based  on  pharmacokinetics  of  gefitinib
          and establishment of review rules

          ABSTRACT   OBJECTIVE  To  analyze  the  potential  adverse  drug  interactions  based  on  pharmacokinetics (PK-pADIs)  of
          gefitinib,  and  establish  its  corresponding  prescription  review  rules.  METHODS  Outpatient  prescriptions  of  gefitinib  combination
          therapy  in  our  hospital  from  January  1,  2022  to  November  30,  2024  were  collected  through  rational  drug  software  system.  PK-
          pADIs  present  in  the  prescriptions  were  identified  based  on  the  Drugs.com   drug  interactions  database.  The  specific  combination
                                                                   ®
          drugs  and  cases  of  PK-pADIs  were  statistically  analyzed,  and  prescription  review  rules  were  established  according  to  the  severity
          classification  of  PK-pADIs.  RESULTS  &  CONCLUSIONS  A  total  of  217  prescriptions  of  gefitinib  combination  therapy  were
          enrolled. Among  them,  28  prescriptions (12.90%),  involving  a  total  of  28  patients,  had  29  cases  of  PK-pADIs,  with  respiratory
          medicine prescriptions (22 prescriptions) being the main type. The combination drugs included proton pump inhibitors (13 cases),
          strong  cytochrome  P450  3A4 (CYP3A4)  inhibitors (7  cases),  H2  receptor  antagonists (4  cases),  CYP3A4  inducers (3  cases),
          and  CYP2D6  substrates (2  cases). The  severity  classifications  for  these  interactions  were  severe,  moderate,  severe,  moderate  and
          moderate, respectively. Based on the above severity classification of PK-pADIs, four prescription review rules had been established
          as follows: when gefitinib was combined with acid-suppressing drugs, it should be subject to “manual review”; when gefitinib was
          combined with dexamethasone, metoprolol, or strong CYP3A4 inhibitors, an “alert” should be triggered, and the physician should
          be  informed  via  an  alert  box  to  strengthen  the  monitoring  of  relevant  indicators.  Clinical  pharmacists  need  to  conduct  in-depth
          training  on  knowledge  related  to  gefitinib  drug  interactions  in  key  clinical  departments  such  as  respiratory  medicine.  They  should
          strengthen  the  monitoring  and  guidance  of  rational  drug  use  for  patients  who  are  on  long-term  gefitinib  therapy,  and  promptly
          identify and intervene in PK-pADIs, thereby enhancing the rationality, safety, and effectiveness of clinical drug use.
