This study presents the in-capillary enzymatic biotransformation of dextromethorphan, an antitusive drug and opioid receptor antagonist, and subsequent electrophoretic separation of its products. The study includes the optimization of separation parameters to fulfill the requirements of an online microreaction. The analyses were performed in a bare fused-silica capillary using 100 mM sodium tetraborate (pH 10.0) mixed with linear polyacrylamide (20%, v/v) and 2-propanol (10%, v/v). This BGE was suitable for monitoring both off-line and in-capillary incubations. The partial filling technique enabled the enzymatic reaction to be carried out in its optimal environment (20 mM sodium phosphate, pH 7.4). Finally, in-capillary microreaction in the presence of cytochrome P450 3A4 gave satisfactory outcomes.
