SUMMARY OF PRODUCT CHARACTERISTICS

1 NAME OF THE MEDICINAL PRODUCT

Cefuroxime 250mg Powder for Solution for Injection

2 QUALITATIVE AND QUANTITATIVE COMPOSITION

Each vial contains cefuroxime sodium equivalent to 250 mg cefuroxime. Each vial contains approximately 14 mg sodium.

For a full list of excipients, see section 6.1.

3 PHARMACEUTICAL FORM

Powder for solution for injection.

Cefuroxime is white to faintly yellow powder.

4    CLINICAL PARTICULARS

4.1    Therapeutic indications

Cefuroxime is indicated for the treatment of the following infections when caused by susceptible organisms.

Respiratory tract infections: acute exacerbation of chronic bronchitis, hospital acquired pneumonia, severe community acquired pneumonia.

Upper urinary tract infections: pyelonephritis.

Peri-operative prophylaxis against infection in abdominal, orthopaedic and cardiac surgery.

Consideration should be given to official guidance on the appropriate use of antibacterial agents.

4.2 Posology and method of administration

Usual dosage _ for adolescents (aged 12 years to 17 years), adults and the elderly:

The dosage is 1.5 g/day to 6 g/day. In most infections a sufficient dose is 750 mg every 8 hour. In more severe infections the dose should be increased to 1.5 g every 8 hour by intravenous injection.

If necessary, the dosage frequency can be increased to every 6 hour up to total daily dose of 6g.

Prophylaxis

The usual dose is 1500 mg (1.5 g) intravenously with induction of anaesthesia for abdominal and orthopaedic operations, but may be supplemented with two 750 mg intramuscular doses eight and sixteen hours later. In cardiac operations, the usual dose is 1500 mg (1.5 g) intravenously with induction of anaesthesia continuing with 750 mg intramuscularly three times daily for a further 24 hours to 48 hours.

Dosage in impaired renal function for adolescents, adults and elderly It is not necessary to reduce the dose if creatinine clearance is more than 20 ml/min. The recommended maintenance dose in impaired renal function is as follows:

Creatinine clearance (ml/min)	Recommended dosage of cefuroxime (mg)	Frequency of dosage (hours)
>20	Normal dose
10-20	750	12
<10	750	24
Patients on continuous arteriovenous haemofiltration/haemo-dialysis	750	12

Special precautions are required if creatinine clearance is <10 ml/minute and treatment should take place under appropriate expert supervision (see section 4.4).

Serum concentration of cefuroxime should be monitored in patients with severe renal impairment.

For patients on haemodialysis a further 750 mg dose, by intravenous or intramuscular injection, should be given at the end of each session.

For low-flux haemofiltration follow the dosage recommended under impaired renal function.

Paediatric patients

Preterm (born at <36 weeks of gestation) and term newborn infants (age 0-27 days):

Cefuroxime is not recommended for the use in these age groups due to insufficient data on safety and efficacy. In the first weeks of life the serum half-life of cefuroxime can be three to five times that in adults (see section 5.2).

Infants, toddlers (age 28 days to 23 months) and children (2 years to 11 years):

The recommended dosage range is 30 to 100 mg/kg/day given as three or four divided doses. Most infections will respond to a dose of 60 mg/kg/day.

Infants, toddlers (28 days to 23 months) and children (2 years to 11 years) with impaired renal function:

There are insufficient data regarding use of cefuroxime in paediatric renal insufficiency and therefore such use is not recommended.

Route of Administration:

Cefuroxime 250mg Powder for Solution for Injection may be administered by intramuscular injection or intravenous injection (within 3-5 minutes), see section 6.6.

Intramuscular administration should be limited on special indication and/or exceptional clinical situations after benefit-risk-assessment. Intramuscular administration 3 times a day is not recommended.

Doses above 750 mg of cefuroxime should not be administered intramuscularly.

4.3 Contraindications

•    Hypersensitivity to cefuroxime or to any of the cephalosporins.

•    Previous immediate and/or severe hypersensitivity reaction to penicillin or to any other type of beta-lactam medicinal products.

4.4 Special warnings and precautions for use

Special care is indicated in patients who have experienced an allergic reaction to penicillins or beta-lactam antibiotics as cross-reactions may occur (for contraindications due to known hypersensitivity reactions see section 4.3).

If after administration of cefuroxime sodium hypersensitivity reactions occur, the use of cefuroxime sodium should be discontinued immediately and an appropriate treatment measures should be initiated.

Special care should be taken in patients with hepatic dysfunction.

As with other antibiotics, use of cefuroxime sodium may result in the overgrowth of Candida. Prolonged use may also result in the overgrowth of other non-susceptible organisms (e.g. Enterococci and Clostridium difficile), which may require interruption of treatment.

In patients who develop severe diarrhoea during or after use of cefuroxime sodium, the risk of life threatening pseudo-membranous colitis should be taken into account. The use of cefuroxime sodium should be discontinued and the appropriate treatment established. Anti-peristaltics are contra-indicated.

Cefuroxime solution is incompatible with aminoglycoside antibiotics (see section 6.2).

The use of cefuroxime may be accompanied by a false positive Coombs test. This may interfere with the performance of cross matching tests with blood (see section 4.8).

Cefuroxime is excreted via the kidneys. Therefore a dose adjustment is required in patients with impaired renal function (see section 4.2).

Due to an increased risk of cefuroxime accumulation in serum accompanied by an increased risk for undesirable effects patients with a creatinine clearance < 10 ml/min should be treated under expert supervision.

As a precaution, renal function should be monitored if renal function is already impaired.

The sodium content of cefuroxime should be taken into account when prescribed to patients requiring sodium restriction.

There are insufficient data regarding use of cefuroxime in paediatric renal insufficiency and therefore such use is not recommended.

This medicinal product contains less than 1 mmol sodium (23 mg) per vial, i.e. essentially ‘sodium- free’.

4.5 Interaction with other medicinal products and other forms of interaction

Cephalosporin antibiotics at high dosage should be given with caution to patients receiving concurrent treatment with potent diuretics such as furosemide, amphotericin and aminoglycosides, as concomitant use increases the risk of nephrotoxicity.

Bacteriostatic antibiotics may interfere with the bactericidal action of cephalosporins. Therefore, it is advisable to avoid giving tetracyclines, macrolides, or chloramphenicol in conjunction with cefuroxime.

Probenicid inhibits the tubular excretion of cefuroxime. When probenicid is administered concomitantly plasma concentrations of cefuroxime are enhanced.

Cefuroxime does not interfere in enzyme-based tests for glycosuria. Slight interference with copper reduction methods (Benedict's, Fehling's, Clinitest) may be observed. However, this should not lead to false-positive results, as may be experienced with some other cephalosporins.

It is recommended that either the glucose oxidase or hexokinase methods are used to determine blood/plasma glucose levels in patients receiving cefuroxime. This antibiotic does not interfere in the alkaline picrate assay for creatinine.

4.6 Pregnancy and lactation

Pregnancy

Data on a limited number of exposed pregnancies indicate no adverse effects of cefuroxime on the pregnancy or on the health of the foetus/newborn child. To date no other relevant epidemiological data are available. Animal studies do not show any harmful effects on embryonal and foetal development (see section 5.3). Cefuroxime reaches the embryo/foetus via the placenta. Due to the limited clinical experience Cefuroxime 250mg Powder for Solution for Injection should only be used during pregnancy after careful risk/benefit, especially during the first trimester.

Lactation

Cefuroxime is excreted in human milk. Cefuroxime 250mg Powder for Solution for Injection should only be used during lactation after careful risk/benefit assessment. Diarrhoea and fungus infection of the mucous membranes could occur in the breastfed infant, so that nursing might have to be discontinued. The possibility of sensitisation should be borne in mind.

4.7 Effects on ability to drive and use machines

Cefuroxime may sometimes be associated with side effects, such as dizziness, that may impair the ability to drive a vehicle, operate machinery or to work safely.

4.8 Undesirable effects

The following convention has been used for the classification of frequency:

Very common >1/10 Common >1/100 to <1/10 Uncommon >1/1,000 to <1/100 Rare >1/10,000 to <1/1,000

Very rare <1/10,000, not known (cannot be estimated from the available data).

Dependent on the dose and duration of the treatment approximately 3 % of all treated patients are expected to experience one or several of the adverse reactions mentioned below.

System Organ Class	Frequency	Undesirable effects
Infections and infestations	Rare	Pseudomembranous colitis. As with other antibiotics prolonged use may lead to secondary superinfections caused by insusceptible organisms, e.g. Candida, Enterococci and Clostridium difficile (see section 4.4).
Blood and lymphatic system disorder	Uncommon	Eosinophilia, leucopenia, neutropenia, thrombocytopenia
	Rare	Decreased haemoglobin concentration, agranulocytosis

	Very rare	Jaundice
Skin and subcutaneous tissue disorders	Common	Skin rashes, urticaria, pruritus
	Rare	Erythema multiforme, Stevens-Johnson syndrome and toxic epidermal necrolysis
Renal and urinary disorders	Common	Increased levels of creatinine and urea in serum, especially in patients with impaired renal function (see section 4.2 and 4.4)
	Uncommon	Acute interstitial nephritis. Nephrotoxicity. Acute renal tubular necrosis has followed excessive dosage and has also been associated with its use in older patients or those with preexisting renal impairment (see section 4.2 and 4.4).
General disorders and administration site conditions	Common	Pain at the injection site following intramuscular administration, thrombophlebitis and pain following intravenous injection, after rapid intravenous administration heat sensations or nausea may occur
	Rare	Drug fever
Investigations	Not known	The use of cefuroxime may be accompanied by a false positive Coombs test. This may interfere with the performance of cross matching tests with blood.

Reporting of suspected adverse reactions:

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal

product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at: www.mhra.gov.uk/yellowcard.

4.9 Overdose

Overdosage of cephalosporins can cause cerebral irritation leading to convulsions. Serum levels of cefuroxime can be reduced by haemodialysis or peritoneal dialysis.

5 PHARMACOLOGICAL PROPERTIES

5.1 Pharmacodynamic properties

Pharmacotherapeutic group: Second generation cephalosporin

ATC code: J01D C02

Mode of action

All cephalosporins 03-lactam antibiotics) inhibit cell wall production and are selective inhibitors of peptidoglycan synthesis. The initial step in drug action consists of binding of the drug to cell receptors, called Penicillin-Binding Proteins. After a P-lactam antibiotic has bound to these receptors, the transpeptidation reaction is inhibited and peptidoglycan synthesis is blocked, resulting in bacterial lysis.

PK/PD relationship

The efficacy is mainly determined by the length of time, during which the drug level is above the minimal inhibitory concentration of the pathogen

Mechanism of resistance

Bacterial resistance to cefuroxime may be due to one or more of the following

mechanisms:

•    hydrolysis by beta-lactamases. Cefuroxime may be efficiently hydrolysed by certain of the extended-spectrum beta-lactamases (ESBLs) and by the chromosomally-encoded (AmpC) enzyme that may be induced or stably depressed in certain aerobic gram-negative bacterial species

•    reduced affinity of penicillin-binding proteins for cefuroxime

•    outer membrane impermeability, which restricts access of cefuroxime to penicillin binding proteins in gram-negative organisms

•    drug efflux pumps

Methicillin-resistant staphylococci (MRS) are resistant to all currently available P-lactam antibiotics including cefuroxime.

Penicillin-resistant Streptococcus pneumoniae are cross-resistant to cephalosporins such as cefuroxime through alteration of penicillin binding proteins.

Beta-lactamase negative, ampicillin resistant (BLNAR) strains of H. influenzae should be considered resistant to cefuroxime despite apparent in vitro susceptibility.

Strains of Enterobacteriaceae, in particular Klebsiella spp. and Escherichia coli that produce ESBLs (extended spectrum p-lactamase) may be clinically resistant to therapy with cephalosporins despite apparent in vitro susceptibility and should be considered as resistant.

Breakpoints

EUCAST (European Committee on Antimicrobial Susceptibility Testing) breakpoints:

Organisms	Susceptible	Resistant
Enterobacteriaceae 1	< 8 mg/l	> 8 mg/l
Staphylococcus spp.	_*	_*
Streptococcus spp. (A, B, C, G)	< 0,5 mg/l	> 0,5 mg/l
Streptococcus pneumoniae	< 0,5 mg/l	> 1 mg/l
Haemophilus influenzae	< 1 mg/l	> 2 mg/l
Moraxella catarrhalis	< 1 mg/l	> 2 mg/l
Non-species related **	< 4 mg/l	> 8 mg/l

¹ The breakpoint pertains to a dosage of 1.5 g x 3 and to E.coli and Klebsiella spp only.

* Susceptibility of staphylococci to cefuroxime is inferred from the methicillin susceptibility.

Methicillin (Oxacillin)-resistant staphylococci are resistant to cephalosporines.

** Based on serum pharmacokinetic.

Susceptability

The prevalence of acquired resistance may vary geographically and with time for selected species and local information on resistance is desirable, particularly when treating severe infections. As necessary, expert advice should be sought when the local prevalence of resistance is such that the utility of the agent in at least some types of infections is questionable.

Bacteroides spp.

Clostridium difficile Others

Chlamydia spp.

Chlamydophila spp.

Legionella spp.

Mycobacterium spp.

The elimination half-life ranges between about 70 and 80 min after intramuscular or intravenous administration in healthy adults. Most of the dose of cefuroxime is excreted unchanged in active form. About 50% is excreted by glomerular filtration and about 50% through renal tubular secretion within 24 hours, with the majority being eliminated within 6 hours; high concentrations are achieved in the urine. Small amounts of cefuroxime are excreted in bile. The renal clearance is 136.0 and 169.6 ml/min/1.73 m² after 0.5 and 1 g cefuroxime intravenous and 137.9 and 146.3 ml/min/1.73 m² after 0.750 and 1 g cefuroxime intramuscular, respectively. The elimination is impaired in patients with impaired renal function.

Concomitant administration of oral probenecid slows tubular secretion of cefuroxime and decreases renal clearance by approximately 40%.

Oral probenecid (1 g) prolonged the half-life by 63% and increased the area under the concentration-time curve of intravenous cefuroxime (750 mg) by up to 50%.

Cefuroxime is dialysable and small amounts are removed by peritoneal dialysis.

Linearity/non-linearity

The peak plasma concentration and the area under the concentration curve increase with increasing dose.

Pharmacokinetics in special patient groups

The half-life of cefuroxime is prolonged in patients with renal impairment associated with the risk of accumulation. The serum half-life is 4.2 hours at a creatinine clearance of 23 ml/min and 22.3 hours at a creatinine clearance of 5 ml/min. Therefore dose adjustment is required in patients with impaired renal function (see section 4.2).

The serum half-life is prolonged in preterm and term newborn infants during the first weeks of life (3 to 5 times the value in adults).

5.3 Preclinical safety data

Effects in non-clinical studies were observed only at exposures considered sufficiently in excess of the maximum human exposure indicating little relevance to clinical use. Preclinical nephrotoxicity studies showed the product can cause renal damage in some species when administered in very high doses. Its nephrotoxicity increases when administered in combination with glycerol and furosemide.

The most prominent treatment-related effect was tissue damage at the injection sites.

A cefuroxime ester did not show clinically relevant effects when tested in vitro and in vivo for genotoxic potential. No long-term investigations for the determination of a tumorigenic potential were performed.

Investigations in rabbits and mice did not demonstrate reproductive toxicity or teratogenic-effects. Cefuroxime has been shown to pass the placenta.

Gamma-glutamyl transpeptidase activity in rat urine is inhibited by various cephalosporins, however, the level of inhibition is less with cefuroxime. This may have significance in the interference in clinical laboratory tests in humans.
