Hướng dẫn pha thuốc
Intravenous:
Endometritis,Gynaecological infections: Add 13 ml of sterile water for injection or sodium chloride inj to a vial labeled as containing a combined potency of 3.1 g. This will provide a solution containing approx ticarcillin 200 mg/ml and clavulanic acid 6.7 mg/ml. This may be further diluted to 10-100 mg/ml in a compatible IV solution for intermittent infusion.

Tương kỵ
Ticarcillin is incompatible with sodium bicarbonate and aminoglycosides.
Chống chỉ định
Hypersensitivity to penicillins.
Thận trọng
Restricted sodium diet. Restricted sodium diet. Very high doses in poor renal function (risk of neurotoxicity) or heart failure. Avoid contact; skin sensitisation may occur. Monitor electrolyte concentrations, renal, hepatic and hematologic function periodically during prolonged therapy. Discontinue therapy if bleeding manifestations occur. Lactation.
Phản ứng phụ
Hypersensitivity reactions, GI disturbances, pseudomembranous colitis, blood dyscrasias, transient increase in liver enzymes, hepatitis, cholestatic jaundice, giddiness, neuromuscular hyperirritability, seizures, electrolyte disturbances, decreased serum uric acid concentration, increased serum creatinine and/or BUN concentrations. Thrombophlebitis and local reactions at the IV infusion site. Haemorrhagic cystitis especially in cystic fibrosis patients.
Potentially Fatal: Anaphylaxis.
Quá liều
Overdosage may cause neurotoxic effects, especially in patients with renal impairment. Treament is supportive and symptomatic. Haemodialysis can be used to enhance elimination of both ticarcillin and clavulanic acid.
Tương tác
Probenecid decreases clearance of ticarcillin. Increased bleeding risk with warfarin, acenocoumarol. Possible increase in ciclosporin, methotrexate levels with concurrent use. Possible contraceptive failure with combined oral contraceptives.
Lab Interference
May interfere with diagnostic tests for urinary glucose using copper sulfate, direct Coombs' test and test for serum proteins. May interfere with diagnostic tests that use bacteria. High urine concentrations may cause false-positive protein reactions with the following methods: Sulfosalicylic acid and boiling test, acetic acid test, biuret reaction and nitric acid test.
Tác dụng
Description: Ticarcillin and clavulanic acid is a fixed dose combination of ticarcillin disodium (a semisynthetic extended-spectrum penicillin) and the potassium salt of clavulanic acid (a β-lactamase inhibitor). Clavulanic acid, on its own has only weak antibacterial activity, but has a high affinity for β-lactamases that generally inactivate ticarcillin by hydrolysing its β-lactam ring. Hence clavulanic acid synergistically expands ticarcillin's spectrum of activity against many strains of β-lactamase-producing bacteria.
Pharmacokinetics:
Absorption: Absorption from GI: Ticarcillin: Poorly absorbed; clavulanate potassium: Well absorbed.
Distribution: Protein-binding: Ticarcillin 45-65%; clavulanic acid 22-30%. Both distributed into bone, blister and peritoneal fluid. Both cross placenta and distributed into breastmilk. Ticarcillin: Low distribution into CSF, higher when meninges are inflamed.
Metabolism: Clavulanate potassium: Extensively metabolised; ticarcillin: Limited metabolism.
Excretion: Excreted unchanged in urine: Ticarcillin 60-70%; clavulanic acid 35-45%.
Bảo quản
Store below 24°C.
