Target concentration intervention (TCI) is proposed as an alternative conceptual strategy to therapeutic drug monitoring (TDM). It is argued that the idea of a therapeutic range has limited the interpretation of measured drug concentrations and diminished the anticipated clinical benefit to patients by use of an oversimplified pharmacodynamic model. TCI on the other hand embraces pharmacokinetic and pharmacodynamic concepts and uses the idea of a target effect and associated target concentration to make rational individual dose decisions.
目标浓度干预(TCI)被提议作为治疗药物监测(TDM)的一种替代概念策略。有人认为,治疗范围的概念限制了对所测药物浓度的解释,并通过使用过于简化的药效学模型降低了对患者预期的临床益处。另一方面,TCI包含药代动力学和药效学概念,并利用目标效应和相关目标浓度的概念来做出合理的个体化剂量决策。
