Hướng dẫn pha thuốc
Reconstitute vials labelled as 500 mg or 1 g with 10 mL or 20 mL of sterile water for inj, respectively, to provide a final concentration of 50 mg/mL. For IV infusion, may further dilute the reconstituted solution with a compatible infusion fluid (e.g. NaCl 0.9%, dextrose 5% in water) to a final concentration of 1-20 mg/mL. Alternatively, vials for infusion may be directly reconstituted with a compatible infusion fluid.

Significant: CNS effects (e.g. seizure, delirium), fungal or bacterial superinfection (prolonged use), severe cutaneous reactions (e.g. acute generalised exanthematous pustulosis [AGEP], erythema multiforme, Stevens-Johnson syndrome [SJS], toxic epidermal necrolysis [TEN], drug reaction with eosinophilia and systemic symptoms [DRESS]). Blood and lymphatic system disorders: Thrombocythaemia. Gastrointestinal disorders: Nausea, diarrhoea, vomiting, abdominal pain. General disorders and administration site conditions: Inj site inflammation, pain, and thrombophlebitis. Investigations: Increased transaminases, blood alkaline phosphatase, and blood LDH. Nervous system disorders: Headache, paraesthesia. Skin and subcutaneous tissue disorders: Rash, urticaria, pruritus. Potentially Fatal: Serious hypersensitivity reactions (e.g. anaphylaxis), Clostridioides difficile-associated diarrhoea and pseudomembranous colitis.
Perform culture and sensitivity tests; consult local institutional recommendations before treatment initiation due to antibiotic resistance risks. Monitor LFT, renal function, and CBC periodically during prolonged treatment. Monitor for signs of anaphylaxis during initiation of treatment.
Tương tác
May decrease the serum concentrations of valproic acid to subtherapeutic levels, thereby increasing the risk of breakthrough seizures. Increased serum concentration and prolonged elimination half-life with probenecid. May enhance the anticoagulant effects of warfarin.

Tác dụng
Description: Mechanism of Action: Meropenem, a synthetic carbapenem β-lactam antibiotic, exhibits bactericidal action against most Gram-positive and Gram-negative bacteria by binding to penicillin-binding proteins (PBPs), which inhibits bacterial cell wall synthesis, thus resulting in cell wall lysis. Pharmacokinetics: Absorption: Time to peak plasma concentration: Approx 1 hour (tissue; except in bile, lung, and muscle); 2-3 hours (CSF; inflamed meninges). Distribution: Extensively distributed into body tissues and fluids including bone, skin, fascia, muscle, peritoneal fluid, urinary tract, gynaecological tissues, lung, bronchial mucosa, bile, heart valves, and CSF. Enters breast milk (small amounts). Volume of distribution: 15-20 L. Plasma protein binding: Approx 2%. Metabolism: Metabolised in the liver via hydrolysis into an inactive form. Excretion: Mainly via urine (approx 70% as unchanged drug; approx 28% as inactive metabolite); faeces (2%). Elimination half-life: Approx 1 hour.
