Cefoperazone and Sulbactam for injection

 

Composition

Each vial contains:

Sterile Cefoperazone Sodium USP

equivalent to Anhydrous Cefoperazone 500mg/ 1000mg

Sterile Sulbactam Sodium USP

equivalent to Anhydrous Sulbactam 500mg/ 1000mg

 

Description

The Sulbactam sodium and Cefoperazone sodium combination consists of a betal lactamase inhibitor plus a betal lactam.

This Sulbactamsoidum and Cefoperazone sodium combination is available as dry powder for reconstitution in a 1:1 ratio. Vials contains the equivalent of 500mg + 500mg (1 g vial), 1000mg (2 g vial) of sulbactam and cefoperazone respectively.

 

Indications

Zifam CS1/CS2 is indicated for the treatment of the following infections when caused by susceptible organisms:

 

 Dosage & Administration

Total dosage(g) Equivalent dosage of Sulbactam + Cefoperazone (g) Volume of diluent conc.(ml) Maximum final dose of Sulbactam + Cefoperazone (mg/ml)
1.0 0.5+0.5 4.0 125+125
2.0 1.0+1.0 8.0 125+125

The usual adult dose of Zifam CS1/CS2 is 2 to 4 g per day (i.e 1 to 2g per day cefoperazone activity, given intravenously or intramuscularly in equally divided dose every 12 hours. In severe or refractory infections the daily dosage of Zifam CS1/CS2 may be increased up to 8 g of the 1:1 ratio may require additional cefoperazone administered separately. Doses should be administered every 12 hours in equally dosage of sulbactam is 4g.

The usual dosage of Zifam CS1/CS2 in children is 40 to 80mg/kg/day (i.e. 20-40 mg/kg/day cefoperazone activity) in 2 to 4 equally divided doses. In severe or refractory infections the daily dosage of Zifam CS1/CS2 may be increased up to 160mg/kg/day of the 1:1 ratio (i.e., 80 mg/kg/day cefoperazone activity) in 2 to 4 equally divided doses.

For neonates in the first week of life, the drug should be given every 12 hours. The maximum daily dosage of sulbactam in pediatrics should not exceed 80 mg/kg/day. If more than 80mg/kg/day of Cefoperazone activity are necessary, additional Cefoperazone should be administered.

 

Intravenous Administration: For intermitted infusion each vial of Zifam CS1/CS2 should be reconstituted with the appropriate amount of 5% dextrose in Water, 0.9% Sodium chloride injection or Water for injection and then diluted to 20ml with the same solution followed by administration over 15 to 60 minutes.

 

Intramuscular Administration: Water for injection should be used for reconstitution. For a concentration of cefoperazone of 250 mg/ml or larger, a two step dilution is required using water for injection followed by 2% lidocaine to approximate a 0.5% lidocaine solution. LidocaineHCL 2 % is a suitable vehicle for intramuscular administration; however, it is not for initial reconstitution.

 

Adverse Effects

Zifam CS1/CS2 is generally well tolerated. Adverse reactions are mild and transient. The common side effects reported are gastro-intestinal disturbances, hypersensitivity reactions including skin rashes, urticaria, pruritus, interstitial nephritis, drug fever and very rarely anaphylaxis.

Transient pain may be experienced at the site of intramuscular injection and occasionally, thrombophlebitis may follow at the site of intravenous injection.

 

Drug interactions

Zifam CS1/CS2 has been shown to be compatible with Water for injection, 5% dextrose, 0.9% Sodium chloride. Initial reconstitution with Lactated Ringer’s Solution or with 2% lidocaine HCI solution should be avoided since these mixtures has been shown to be incompatible.

However, a two-step dilution process involving initial reconstitution in Water for injection will result in a compatible mixture when further diluted with Lactated Ringer’s Solution. Solutions of Zifam CS1/CS2 and aminoglycosides should not be directly mixed, since there is a physical incompatibility between them. If combination therapy with Zifam CS1/CS2 and an aminoglycoside is contemplated, this can be accomplished by sequential intermittent intravenous infusion provided that a separate secondary intravenous tubing is used, and that the primary intravenous tubing is adequately irrigated with an approved diluent between doses. It is also suggested that doses of Zifam CS1/CS2 be administered throughout the day at times as far removed from the administration of the aminoglycoside as possible.

 

Overdosage

Limited information is available on the acute toxicity of cefoperazone sodium and sulbactam sodium in humans. Overdosage of the drug would be expected to produce manifestations that are principally extensions of the adverse reactions reported with the drug.

The fact that high cerebrospinal fluid concentrations of beta-lactam antibiotics may cause neurological effects, including siezures, should be considered. Because cefoperazone and sulbactam are both removed from the circulation by haemodialysis, these procedures may enhance the elimination of the drug from the body if over dosage occurs in patients with impaired renal function.
