The Effect of Escitalopram on the Pharmacokinetics and Pharmacodynamics of Tramadol in Healthy Subjects

Escitalopram will be given to a panel of 16 healthy subject for 9 days. On the ninth day a single dose of tramadol is administered to the subjects and pharmacokinetic(PK) and pharmacodynamic(PD) measurements are done for the next 24 hours.

It is stated that escitalopram is only a weak inhibitor of CYP2D6 and therefore no effect is seen in Pk or PK of tramadol
