Cephradine is used in the treatment of infections caused by sensitive organisms.
Cephradine is a cephalosporin antibiotic with broad spectrum bactericidal activity against both gram-positive and gram-negative bacteria. Cephradine interferes with the synthesis of bacterial cell wall by inhibiting transpeptidase enzyme. As a result the bacterial cell wall is weakened, the cell swells and then ruptures.
First generation Cephalosporins
Oral: The usual dose is 1-2 gm daily in 2 to 4 divided doses. In severe and prolonged infection, the dose can be increased up to 4 gm daily which should be taken in equally divided doses.
Injection: The usual dose is 2-4 gm daily which should be given intramuscularly or intravenously in 3-4 divided doses. Special dose in the following infections:
Oral: The usual total dose is 25 to 50 mg/kg/day given in 2 to 4 equally divided doses.
Injection: 50 to 100 mg/kg/day in 4 equally divided doses. The usual total dose may be increased up to 200-300 mg/kg/day.
Perioperative prophylaxis: Recommended dose is 1-2 gm by intramuscular or intravenous route; subsequent parenteral or oral doses are given as appropriate. Therapy should be continued for a minimum of 48-72 hrs. after the patient becomes asymptomatic or evidence of bacterial eradication has been obtained.
Side effects include nausea, vomiting, diarrhoea and abdominal discomfort. Allergic reactions including skin rashes, urticaria, eosinophilia, angioedema and anaphylaxis may occur and elevation of hepatic enzyme values have been noted. Neutropenia has been reported. Super-infection with resistant microorganisms, particularly candida, may follow the treatment. There is also a possibility of development of pseudomembranous colitis. Transient pain may be experienced at the injection site. Thrombophlebitis has been reported following intravenous administrations.
There is evidence of partial cross allergenicity between the penicillins and the cephalosporins. Therefore cefradine should be used with caution in those patients with known hypersensitivity to penicillins.
Increased risk of nephrotoxicity with loop diuretics. Decreased renal clearance with probenecid.
Although there have been no reports of adverse effect on the fetus, safety of use during pregnancy has not been definitely established. The drug should be used during pregnancy only when clearly indicated. Cephalosporins are distributed into breast milk and the drug should be used with caution in nursing mother.
Patients with known hypersensitivity to the cephalosporin antibiotics.
Powder for Suspension: For the suspension, shake the bottle well before adding water. Then add 60 ml of boiled and cooled water (with the help of the provided cup) to thebottle. Then continue shaking the bottle gently until the powder is mixed properly. Shake the bottle well before each use.

500 mg Intramuscular Injection: Add 2.0 ml of water for injection to 500 mg vial and shake.
500 mg Intravenous Injection: Add 5.0 ml of water for injection to 500 mg vial and shake. The solution should be slowly injected directly into a vein over a 3 to 5 minutes period.
1 gm Intramuscular Injection: Add 4.0 ml of water for injection to 1 gm vial and shake.
1 gm Intravenous Injection: Add 10.0 ml of water for injection to 1 gm vial and shake. The solution should be slowly injected directly into a vein over a 3 to 5 minutes period.
Cephradine capsule should be kept below 30° C. Cephradine dry powder for suspension should be kept below 25° C & powder vial for injection should be kept below 25° C.
The reconstituted suspension, forte suspension and paediatric drops should be used within 7 days of preparation if kept at room temperature or within 14 days if kept in a refrigerator.
The Cephradine solution should be protected from bright or direct sunlight. All strengths of reconstituted products should be used immediately.
The reconstituted Cephradine injection solution should be used within 2 hours of preparation if kept at room temperature or within 12 hours when refrigerated at 2° to 8° C.
Dosage in renal impairment: In patients with impaired renal function, doses and frequency of administration of cephradine must be modified according to the degree of impairment, severity of infection, susceptibility of the causative organism and serum concentration of the drug. For adults, a loading dose of 750 mg should be given subsequently followed by 500 mg with the mentioned time interval:
CrCl >20 ml/min: Time interval 6-12 hours
CrCl 15-19 ml/min: Time interval 12-24 hours
CrCl 10-14 ml/min: Time interval 24-40 hours
CrCl 5-9 ml/min: Time interval 40-50 hours
CrCl <5 ml/min: Time interval 50-70 hours
