Phản ứng phụ
Fever, rash, nausea, diarrhoea, vomiting, eosinophilia, leucopenia, neutropenia, thrombocytopenia, agranulocytosis, hepatotoxicity, increased AST, acute interstitial nephritis, haematuria, serum sickness-like reactions.
Potentially Fatal: Anaphylactic shock w/ collapse, Clostridium difficile-associated diarrhoea (CDAD).
IM/IV/Parenteral: B
MonitoringParameters
Monitor blood cultures, WBC, differential cell counts, urinalysis, BUN, serum creatinine, AST and ALT values. Observe for signs and symptoms of anaphylaxis during 1st dose.
Quá liều
Symptoms: Neuromuscular hypersensitivity (e.g. agitation, hallucinations, asterixis, encephalopathy, confusion, and seizures), electrolyte imbalance (if the preparation contains K or Na salts, esp in renal failure). Management: Symptomatic and supportive treatment.
Tương tác
Tetracycline may antagonise the bactericidal effect of oxacillin. Enhanced plasma concentrations by probenecid.
Lab Interference
May interfere w/ urinary glucose tests using cupric sulfate (Benedict's soln). False-positive urinary and serum proteins.
Tác dụng
Description: Oxacillin inhibits bacterial cell wall synthesis by binding to 1 or more of the penicillin-binding proteins (PBPs); which in turn inhibits the final transpeptidation step of peptidoglycan synthesis in bacterial cell walls. Bacteria eventually lyse due to ongoing activity of cell wall autolytic enzymes (autolysins and murein hydrolases) while cell wall assembly is arrested.
Pharmacokinetics:
Absorption: Incompletely absorbed from the GI tract. Absorption is reduced by the presence of food. Time to peak plasma concentration: 1 hr (oral); 30 min (IM).
Distribution: Distributed into synovial, pleural pericardial and ascitic fluids; bone, lungs, sputum and bile; cord serum and amniotic fluid. Crosses the placenta and enters breast milk. Volume of distribution: 0.39-0.43 L/kg. Plasma protein binding: Approx 93%.
Metabolism: Partially metabolised to active and inactive metabolites in the liver.
Excretion: Via urine (oral: approx 20-30%; IM: >40%) as unchanged drug and metabolites and bile. Plasma half-life: Approx 30 min.
