Brief summary
The pharmacokinetics of 50 mg BIBR 1048 administered as two newly developed capsule formulation using melt extrusion technology was assessed in two separate, single dose, 3-way crossover, open design, randomised studies. The 3-way crossover treatments included administration of the tartaric acid solution of 50 mg BIBR 1048, the capsule formulation A or B and administration of the capsules with coadministration of pantoprazole.
Interventions
BIBR 1048 MS, formulation A 50 mg
BIBR 1048 MS, formulation B 50 mg
BIBR 1048 MS, powder plus solution 50 mg
Pantoprazole 40 mg
