Pharmacokinetics

Dihydrocodeine concentrations at the effect site were obtained by convolution of a first-order transfer function with the function describing the plasma concentration versus time courses. Miotic effects were related to effect-site concentrations by a sigmoidal pharmacodynamic model. In contrast to the rapid clearance of dihydro codeine from blood in the 14-year-old girl (apparent half-life of 3 hours), the 1-month-old baby boy still had high serum concentrations.

Dosage Studied

Zomepirac was statistically better than dihydrocodeine in the multiple dosing phase. Concurrent dosing of dihydROcodeine and ebastine produced a significant place preference. On the other hand, concurrent dosing with methylephedrine (4 mg/kg) and a mixture (SC) of caffeine (4mg/kg), chlorpheniramine (0.5mg/ kg) produced a positive effect.
