Metabolism and Pharmacokinetics of [14C]-BIIL 284 BS in Healthy Volunteers

The aims of this phase I study are to define the metabolism, excretion and pharmacokinetics of \[14C\]-BIIL 284 BS after administration of a single oral dose of 25 mg \[14C\]-BIIL 284 BS in 6 healthy volunteers. Tolerability was also assessed.
