  • Title: Pharmacokinetic study of trimebutine maleate in rabbit blood using in vivo microdialysis coupled to capillary electrophoresis.
    Author: Wang L, Zhang Z, Yang W.
    Journal: J Pharm Biomed Anal; 2005 Sep 15; 39(3-4):399-403. PubMed ID: 15939564.
    Abstract:
    In vivo microdialysis was used together with capillary electrophoresis (CE) to monitor the concentration of trimebutine maleate (TM) in rabbit blood. Dialysis probe was perfused at 3 microl/min resulting in relative recovery of 26.6+/-3.1% (n=3). After a one step sample preparation the samples were injected directly into the capillary. TM was detected on-column using UV detector at 214 nm. Separation of TM from other components in the dialysate was achieved within 15 min. Evaluation was based on the relative collected peak height (TM/IS). The response for TM in the blood dialysate was linear over the range of 0.5-100 microg/ml. The detection limit of TM in the blood dialysate was 0.1 microg/ml (S/N=3). This method has been successfully applied to the pharmacokinetic study of trimebutine maleate in rabbit blood following oral administration of 200 mg/kg. It provides a fast and simple technique for the pharmacokinetic study of TM in vivo.
