Child: Dosage is individualised depending on the severity of the infection and clinical judgement. <30 kg: 25-50 mg/kg daily in 2 divided doses; ≥30 kg: Same as adult dose.

Musculoskeletal and connective tissue disorders: Arthralgia. Nervous system disorders: Headache, dizziness. Skin and subcutaneous tissue disorders: Pruritus, rash. Potentially Fatal: Hypersensitivity reactions (e.g. anaphylaxis).
Chỉ số theo dõi
Monitor for signs of anaphylaxis during 1st dose. Monitor haematologic, renal, and hepatic function periodically during prolonged use. May perform culture and susceptibility tests prior to treatment initiation; consult local institutional recommendations before treatment initiation due to antibiotic resistance risks.
Tương tác
Increased incidence of rashes with allopurinol. May enhance the effect of anticoagulants. Bacteriostatic drugs (e.g. chloramphenicol, erythromycin, sulfonamides, tetracyclines) may interfere with the bactericidal effect of sultamicillin. Diminished therapeutic efficacy of estrogen-containing oral contraceptives. Decreased clearance of methotrexate thus increase toxicity. Increased and prolonged serum concentrations with probenecid.

Tác dụng
Description: Mechanism of Action: Sultamicillin is a prodrug of ampicillin and sulbactam linked as a double ester. Ampicillin prevents bacterial cell wall synthesis by binding to 1 or more of the penicillin-binding proteins resulting in inhibition of the final transpeptidation step of peptidoglycan synthesis in the bacterial cell walls. Sulbactam extends the spectrum of ampicillin activity due to its irreversible inhibition of β-lactamases that are found in penicillin-resistant organisms. It has limited antibacterial activity to Neisseriaceae. Pharmacokinetics: Absorption: Absorbed from the gastrointestinal tract. Bioavailability: 80%. Distribution: Crosses the placenta, enters breast milk (small amounts). Distributed in the bile, blister, and tissue fluids; penetrates the CSF with inflamed meninges only. Plasma protein binding: 28% (ampicillin); 38% (sulbactam). Metabolism: Metabolised via hydrolysis to provide a 1:1 molar ratio of ampicillin and sulbactam. Excretion: Via urine (50-75% as unchanged drug). Elimination half-life: Approx 0.75 hour (sulbactam); 1 hour (ampicillin).
