Quá liều
Symptoms: Neurological effects including convulsions. Management: May be removed by haemodialysis.
Tương tác
Increased and prolonged serum levels w/ probenecid. Increased incidence of rashes w/ allopurinol. May reduce effectiveness of oestrogen-containing OC. May increase risk of methotrexate toxicity. Bacteriostatic drugs (e.g. chloramphenicol) may interfere w/ the bactericidal effect of ampicillin. Additive effect w/ anticoagulants.
Lab Interference
False positive urine glucose test using cupric sulfate (e.g. Clinitest®, Benedict's soln, Fehling's soln).
Tác dụng
Description: Ampicillin binds to 1 or more of the penicillin-binding proteins (PBPs), thus inhibiting the final transpeptidation step of peptidoglycan synthesis in bacterial cell walls. Sulbactam inhibits the activity of β-lactamases and extends the spectrum of ampicillin to include β-lactamase producing organisms.
Pharmacokinetics:
Absorption: Ampicillin: Moderately well absorbed from the GI tract. Time to peak plasma concentration: Approx 1-2 hr. Sulbactam: Poorly absorbed from the GI tract.
Distribution: Ampicillin: Widely distributed; therapeutic conc achieved in ascitic, pleural and joint fluids; a little diffusion into CSF except when meninges are inflamed. It crosses the placenta and enters breast milk (small amounts). Plasma protein binding: Approx 20%. Sulbactam: Widely distributed in bile, blister and tissue fluids; distributed in CSF when meninges are inflamed. Plasma protein binding: 38%.
Metabolism: Ampicillin: Converted to some extent to penicilloic acid. Sulbactam: Undergoes enterohepatic recycling.
Excretion: Ampicillin: Via urine (approx 20-40% of oral dose as unchanged drug); faeces. Plasma half-life: Approx 1-1.5 hr. Sulbactam: Via urine (approx 75-85% as unchanged drug). Elimination half-life: 1-1.3 hr.
Bảo quản
