Linezolid in Healthy Volunteers

February 13, 2019 updated by: Sutep Jaruratanasirikul, Prince of Songkla University

Pharmacokinetics/Pharmacodynamics of Oral Linezolid 300 mg/Day in Healthy Volunteers

Linezolid is the first synthetic antibiotic of oxazolidinone group that can inhibit bacterial protein synthesis. Previous studies have found that linezolid was an effective treatment for multidrug-resistant (MDR) and extensively drug-resistant (XDR) tuberculosis (TB). In addition, the current dosage recommendation (1,200 mg/day) occasionally resulted in serious adverse events including bone marrow suppression and peripheral neuropathy.

The objective study were determine the pharmacokinetics of oral linezolid 300 mg /day in healthy volunteers. This study conducted in six healthy volunteers. All subject received an oral linezolid 300 mg/day by directly observed treatment (DOT) at the same time each day for 5 days. Blood samples were collected on day 5 at 0, 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 12 and 24 h post dosing. The separated plasma samples were evaluated by ultra-performance liquid chromatography (UPLC). All pharmacokinetic parameters were calculated.
