Summary The disposition of aprindine following a single oral dose can best be described by a two-compartment open model. The mean plasma half-life (t1/2β) increased from 8.0±2.1 h (SD) after a 25 mg dose to 9.4±2.9 h after 50 mg and to 15.8±2.6 h after 100 mg, with a decrease in total plasma clearance (Cl/F) and volume of distribution at steady state (Vdss/F) and during β-phase (Vdβ/F). The area under plasma concentration-time curve (AUC), maximum plasma concentration (Cmax) and the amount of unchanged aprindine excreted in the urine increased in a non-linear fashion with the increase in dose. The t1/2β after multiple oral doses showed a 3-fold increase over the single dose value. These results indicate that aprindine shows dose-dependent non-linear kinetics.
