Pharmacokinetics of fosfomycin in normal and burn patients. Effect of probenecid.
The pharmacokinetics of fosfomycin are modified in burn patients, suggesting a net tubular secretion in such patients. In an attempt to verify this hypothesis, five healthy normal volunteers were studied The pharmacokinetics of fosfomycin were studied with and without probenecid. In the absence of probenecid, the renal clearance of the drug was equal to that of creatinine. With probenecid, the renal clearance of fosfomycin decreased, whereas creatinine clearance did not. This result suggests the existence of a tubular secretion, which might be enhanced in burn patients.
