| Abstract: | Resolution of racemic tiaprofenic acid (TA) has been performed using immobilized human serum albumin as the stationary phase. The eluent was phosphate buffer—acetonitrile—n-octanoic acid (90:10:0.015, v/v). Detection was achieved at 305 nm. The pharmacokinetics of the enantiomers were studied following oral administration into humans and after subcutaneous injection in rats. Plasma concentrations of (+)-TA were much greater than those of (−)-TA. For the rat, the pharmacokinetic parameters between (−)-TA and (+)-TA were all statistically different (p < 0.005). |
