[Interaction of isoxicam and digoxin]

The influence of maintenance therapy with Isoxicam, 200 mg daily, on digoxin steady-state plasma levels was studied on 12 healthy volunteers. One person dropped out from the investigation program on account of cardiac sensations following the invasion phase with digoxin. No statistically significant differences could be shown during concomitant therapy or after withdrawal of Isoxicam. Neither were toxic glycoside plasma concentrations observed. There were no pathological clinicochemical parameters, in particular no changes in renal function values.
