Arm Intervention/treatment
Experimental: Reference
No pre-treatment
Drug: NRL972
Single intravenous administration of 2 mg NRL972
Experimental: T1
Cloxacillin pre- and co-treatment

Primary Outcome Measures :
  1. Total clearance by non-compartmental analysis. Apparent terminal disposition half-life t½ by non-compartmental analysis [ Time Frame: 4 hours post-dose ]

Secondary Outcome Measures :
  1. Non-compartmental PK-analysis based on the extensive profile (up to last quantifiable data point), the 'short' profile (over the first hour after injection), and the two-point profile based on selected data-pairs over the 1st hour after dosing [ Time Frame: 4 hours post-dose ]
