12A study in healthy volunteers to determine whether different drugs metabolised by the liver have any effects on how NRL972 is processed within the body.
Single intravenous administration of 2 mg NRL972 after pre-treatment with 600 mg p.o. rifampicin once daily from the evening of Day D-7 until the evening of Day D-1
Reference test: Single intravenous administration of 2 mg NRL972
Single intravenous administration of 2 mg NRL972 injection after pre-treatment with 100 mg cyclosporine on the evening of Day D-1 and on the morning of Day D01 one hour before administration of NRL972
