5. Gonorrhoea: Acute
uncomplicated gonococcal urethritis and cervicitis.
6. Early lyme disease and
subsequent prevention of late Lyme disease.
Pharmacology
Cefuroxime is a well-characterized and effective antibacterial
agent, which has broad-spectrum bactericidal activity against a wide range of common
pathogens, including β-lactamase producing strains. Cefuroxime has good stability
to bacterial β-lactamase and consequently, is active against many
ampicillin-resistant and amoxycillin-resistant strains.
Composition
Cefuroxime 125 mg tablet: Each film coated tablet
contains Cefuroxime 125 mg as Cefuroxime axetil BP.
Cefuroxime 250 mg tablet: Each film coated tablet

Cefuroxime 500 mg tablet: Each film coated tablet
contains Cefuroxime 500 mg as Cefuroxime axetil BP.
Cefuroxime powder for suspension (70 ml): Each 5 ml
reconstituted suspension contains 125 mg Cefuroxime, as Cefuroxime axetil BP.

750 mg, as Cefuroxime sodium BP.
Cefuroxime 1.5 gm IV injection: Each vial contains
Cefuroxime 1.5 gm, as Cefuroxime sodium BP.
Dosage and Administration
Adults: Most
infections well respond to 250 mg b.i.d. In mild to moderate lower respiratory tract
infections e.g bronchitis 250 mg b.i.d. should be given. For more severe lower
respiratory tract infections or if pneumonia is suspected then 500 mg b.i.d.
should be given.
For urinary tract infections
a dose of 125 mg b.i.d. is usually adequate, in pyelonephritis the recommended dose
is 250 mg b.i.d. A single dose of one gram is recommended for the treatment of uncomplicated
gonorrhea.
Lyme disease in adults and
children over the age of 12 years: The recommended dose is 500 mg b.i.d. for 20
days.
Children:
The usual dose is 125 mg b.i.d. or 10 mg/kg b.i.d. to a maximum of 250 mg
daily.
For otitis media, in
children less than two years of age the usual dosage is 125 mg b.i.d. or 10
mg/kg b.i.d. to a maximum of 250 mg daily and in children over two years of age
250 mg b.i.d. or 15 mg/kg b.i.d. to a maximum of 500 mg daily.
There is no experience in
children under three months of age. The usual course of therapy in seven days. Cefuroxime

equally divided doses every 6 to 8 hours. Use 100 mg/kg/day (not to exceed the
maximum adult dose) for more severe or serious infections.
Bone
and Joint Infections: 150 mg/kg/day (not to exceed the maximum
adult dose) in equally divided doses every 8 hours.
Bacterial
meningitis: Initially 200 to 240 mg/kg/day IV in divided
doses every 8 hours.
Direction for Reconstitution
Cefuroxime 750 mg intramuscular Injection: Add 3 ml water
for injection BP and shake gently for dispersion
For 750 mg intravenous
injection: Add 6 ml water for injection BP and shake gently for dispersion.
For 1.5 mg intravenous
injection: Add 16 ml water for injection BP and shake gently for dispersion.
For Suspension: shake the
bottle well before adding water. Then add 35 ml of boiled and cooled water
(with the help of the provided cup from different company) to the bottle. Then
continue shaking the bottle until the powder is dissolved property.
Contraindication
Cefuroxime is
contraindicated in patients with known allergy to Cephalosporins.
Side Effect
Cefuroxime has been
associated with nausea and vomiting in a small number of patients.
Acute Over dosage
Excessively large dosage of
all cephalosporins can cause cerebral irritation and may cause convulsions.
This complication is unlikely to occur in routine practice unless the patient
is in renal failure hemodialysis or peritoneal dialysis can remove Cefuroxime.
Precaution
As with antibiotics,
prolonged use of Cefuroxime may result in the over growth of non-susceptible organisms
(e.g. Canada enterococci, Clostridium difficult), which may require
interruption of treatment.
Use in Pregnancy and Lactation
While all antibiotics should
be avoided in the first trimester if possible. Cefuroxime has been safety used
in later pregnancy to treat urinary and other infections. The placental
transfer of Cefuroxime into the fetus was studied in 20 women and
therapeutically active concentrations were found in the serum of infants for up
to 6 hours after delivery. Cefuroxime is excreted in human milk and
consequently caution should be exercised when Cefuroxime is administered to a
nursing mother.
Drug Interaction
No potentially hazardous
interactions have been reported.
