PROFUREX Cefuroxime Sodium 750mg Powder for IM/IV Injection 1's
Indications/Uses
Dosage/Direction for Use
Infants and children: Doses of 30 to 100 mg/kg/day, given as three or four divided doses. A dose of 60 mg/kg/day will be appropriate for most infections.
Neonates: Doses of 30 to 100 mg/kg/day, given as two or three divided doses. In the first week of life, the serum half-life of cefuroxime can be three to five times that in adults.
Other Recommendations: Prophylaxis: The usual dose is 1.5 g IV with induction of anesthesia for abdominal, pelvic and orthopedic surgeries, but may be supplemented with two 750 mg IM doses 8 and 16 hours later. In cardiac, pulmonary, esophageal and vascular surgeries, the usual dose is 1.5 g IV with induction of anesthesia. continuing with 750 mg IM every 8 hours for a further 24 to 48 hours.
Total joint replacement: 1.5 g cefuroxime powder may be mixed dry with each pack of methylmethacrylate cement monomer before adding the liquid monomer.
Gonorrhea: 1.5 g cefuroxime should be given as a single dose. This may be given as 2x750 mg injection into different sites, e.g. each buttock.
Dosage in impaired renal function: Cefuroxime is excreted by the kidneys. Therefore, as with all such antibiotics, in patients with impaired renal function it is recommended that the dosage of PROFUREX be reduced to compensate for its slower excretion, except in mild impairment; (GFR>50 mL/min.). In adults with moderate impairment (GFR20-50 mL/min.) only 750 mg every 8 hours is required with marked impairment (GFR10-20 mL/min.) 750 mg every 12 hours is sufficient; and with severe impairment (GFR<10 mL/min.) 750 mg once daily is adequate. For patients on dialysis, a further 750 mg dose should be given at the end of each dialysis.
Administration: Intramuscular: Add 1 mL Water for Injection for 250 mg PROFUREX or 3 mL Water for Injection to 750 mg PROFUREX.
Shake gently to produce an opaque suspension.
Intravenous: Dissolve PROFUREX in Water for Injection using at least 2 mL for 250 mg, at least 6 mL for 750 mg or 15 mL for 1.5 g.
For short intravenous infusion (e.g. up to 30 minutes) 1.5 g may be dissolved in 50 mL Water for Injection.
These solutions may be given directly into the vein or introduced into the tubing of the giving set if the patient is receiving parenteral fluids.
PROFUREX is compatible with the more commonly used intravenous fluids.
Contraindications
Special Precautions
Cephalosporin antibiotics at high dosage should be given with caution to patients receiving concurrent treatment with potent diuretics such as furosemide as these combinations are suspected of adversely affecting renal function. Clinical experience with PROFUREX has shown that this is not likely to be a problem at the recommended dose levels. There is no experimental evidence of embryonic or teratogenic effects attributable to PROFUREX, but as with all drugs, it should be administered with caution during the early months of pregnancy.
PROFUREX does not interfere in the enzyme-based tests for glycosuria. Slight interference with copper reduction methods (Benedict's, Fehlings, Clinitest) may be observed. However, this should not lead to false-positive results, as may be experienced with some other cephalosporins.
PROFUREX may cause false-negative reactions in the ferricyanide test. Some cephalosporins can cause a falsely high reading in the alkaline picrate assay for creatinine, although the degree of elevation is unlikely to be of clinical importance. It is possible that cefuroxime may also interfere with this determination.
As with other antibiotics, prolonged use may result in the over-growth of non-susceptible organisms.
Adverse Reactions
The principal changes in hematological parameters seen in some patients are decreased hemoglobin concentration and eosinophilia.
A positive Coomb's test has been found in some patients treated with cefuroxime- this phenomenon can interfere with the crossmatching of blood.
Although there are sometimes transient increases in serum liver enzymes and serum bilirubin, particularly in patients with pre-existing liver disease, there is.no evidence of hepatic involvement.
There may also be some variation in the results of biochemical tests of renal function, but these do not appear to be of clinical importance. As a precaution, renal functions should be monitored if this is already impaired.
Transient pain may be experienced at the site of intramuscular injection. This is more likely to occur with higher doses. However, it is unlikely to be a cause for discontinuation of treatment.
Caution For Usage
The color of prepared solution and suspension of PROFUREX may darken on storage.
PROFUREX is compatible with the more commonly used intravenous infusion fluids. It will retain potency for up to 24 hours at room temperature in Sodium Chloride Injection BP 0.9% w/v, 5% Dextrose Injection BP, 0.18% w/v Sodium chloride plus 4% Dextrose Injection BP and Compound Sodium Lactate Injection BP (Hartmann's Solution). The pH of 2.74% w/v Sodium Bicarbonate Injection BP considerably affects the color of the solution is not recommended for the dilution of PROFUREX. However, if required, for patients receiving Sodium Bicarbonate Injection by infusion PROFUREX may be introduced into the tube of the giving set.
Storage
Suspension of PROFUREX for intramuscular injection and aqueous solutions for direct intravenous injection retain their potency for 5 hours if kept at temperatures not exceeding 25°C and for 48 hours if refrigerated. More diluted solutions, i.e. 1.5 g plus 50 mL Water for Injection, retain their potency for 24 hours if kept at temperatures not exceeding 25°C and for 72 hours if refrigerated.
Action
Microbiology: Bacteriology: PROFUREX is highly active against Staphylococcus aureus, including strains which are resistant to penicillin (but not the rare methicillin-resistant strains); Staphylococcus epidermidis, Haemophilus influenzae, Klebsiella spp., Enterobacter spp., Streptococcus pyogenes, Escherichia coli, Streptococcus mitis (viridans group), Clostridium spp., Proteus mirabilis, Proteus rettgeri, Salmonella typhi, Salmonella typhimurium, and other Salmonella spp., Shigella spp., Neisseria spp., (including 6-lactamase producing strains of N. gonorrheae) and Bordetella pertussis. It is also moderately active against strains of Proteus vulgaris, Proteus morgani, and Bacteroides fragilis.
In vitro, the activity of PROFUREX and aminoglycoside antibiotics in combination have been shown to be at least additive with occasional evidence of synergy.
