“…In all cases, duplicate extraction recoveries did not differ by more than 6.5%. Literature studies have confirmed similar extraction recoveries from plasma, irrespective of irinotecan concentration: published recoveries were 66%-70% upon deproteinization with three volumes of 0.1% of acetic acid in methanol relative to plasma sample volume, or with one volume of acetonitrile relative to plasma sample volume 3,10,27 .…”

“…Within this time range, irinotecan levels are typically above or at the LOQ of the here-in proposed assay in plasma matrix 2,24 . Additionally, quantifying irinotecan in plasma of treated patients within 0.5-3.0 h from drug infusion, when irinotecan levels are in the upper region of the therapeutic window is considered sufficient to decide on whether a subsequent dose adjustment is required 10 . Our assay in plasma may thus be useful for the purposes of personalised dose adjustment, or for calculating irinotecan AUC based on PK models.…”

“…Teófilo et al used the DPV method to screen ecstasy compounds in the body using a boron-doped diamond electrode (BDD) [85]. In other research, DPV combined with solid phase extraction was used to measure irinotecan in a plasma matrix [86]. Huang, et al used a type of DPV with a triple application to increase sensitivity for the detection of DNA, as illustrated in Figure 10 [87].…”

“…CYP3A4, cytochrome P-450; UGT1A1/7, UDPglucuronosyltransferase; CE, liver carboxylase adsorptive stripping square wave voltammetry and differential pulse voltammetry. These techniques were successfully applied to the detection of CPT-11 in biological samples [21][22][23]. A simple and efficient fluorimetric assay to detect the active metabolite SN-38 was also validated in plasma [24].…”
