Ceftazidime description
Ceftazidime is a semisynthetic, broad-spectrum, beta-lactam antibiotic for parenteral administration. It is the pentahydrate of pyridinium, 1-acetyl]amino]-2-carboxy-8-oxo-5-thia-1-azabicyclooct-2-en-3-yl]methyl]-, hydroxide, inner salt, ].
It has the following structure :
The empirical formula is C22H32N6O12S2, representing a molecular weight of 636.6.
FORTAZ is a sterile, dry-powdered mixture of ceftazidime pentahydrate and sodium carbonate. The sodium carbonate at a concentration of 118 mg/g of ceftazidime activity has been admixed to facilitate dissolution. The total sodium content of the mixture is approximately 54 mg (2.3 mEq)/g of ceftazidime activity.
FORTAZ in sterile crystalline form is supplied in vials equivalent to 500 mg, 1 g, 2 g, or 6 g of anhydrous ceftazidime and in ADD-Vantage vials equivalent to 1 or 2 g of anhydrous ceftazidime. Solutions of FORTAZ range in color from light yellow to amber, depending on the diluent and volume used. The pH of freshly constituted solutions usually ranges from 5 to 8.
FORTAZ is available as a frozen, iso-osmotic, sterile, nonpyrogenic solution with 1 or 2 g of ceftazidime as ceftazidime sodium premixed with approximately 2.2 or 1.6 g, respectively, of Dextrose Hydrous, USP. Dextrose has been added to adjust the osmolality. Sodium hydroxide is used to adjust pH and neutralize ceftazidime pentahydrate free acid to the sodium salt. The pH may have been adjusted with hydrochloric acid. Solutions of premixed FORTAZ range in color from light yellow to amber. The solution is intended for intravenous (IV) use after thawing to room temperature. The osmolality of the solution is approximately 300 mOsmol/kg, and the pH of thawed solutions ranges from 5 to 7.5.
The plastic container for the frozen solution is fabricated from a specially designed multilayer plastic, PL 2040. Solutions are in contact with the polyethylene layer of this container and can leach out certain chemical components of the plastic in very small amounts within the expiration period. The suitability of the plastic has been confirmed in tests in animals according to USP biological tests for plastic containers as well as by tissue culture toxicity studies.
Tazicef (ceftazidime for injection, USP) is a sterile, dry-powdered mixture of ceftazidime pentahydrate and sodium carbonate. The sodium carbonate at a concentration of 118 mg/gram of ceftazidime activity has been admixed to facilitate dissolution. The total sodium content of the mixture is approximately 54 mg (2.3 mEq)/gram of ceftazidime activity.
Tazicef in sterile crystalline form is supplied in vials equivalent to 1 gram or 2 grams of anhydrous ceftazidime, in piggyback vials equivalent to 1 gram or 2 grams of anhydrous ceftazidime and in ADD-Vantage vials equivalent to 1 gram or 2 grams of anhydrous ceftazidime. Solutions of Tazicef range in color from light yellow to amber, depending on the diluent and volume used. The pH of freshly reconstituted solutions usually ranges from 5.0 to 7.5.
Ceftazidime for injection, USP is a sterile, dry-powdered mixture of ceftazidime pentahydrate and sodium carbonate. The sodium carbonate at a concentration of 118 mg/g of ceftazidime activity has been admixed to facilitate dissolution. The total sodium content of the mixture is approximately 54 mg (2.3 mEq)/g of ceftazidime activity.
Ceftazidime for injection, USP is a white to cream-colored crystalline powder. Solutions of ceftazidime for injection, USP range in color from light yellow to amber, depending on the diluent and volume used. The pH of freshly constituted solutions usually ranges from 5 to 8.
Ceftazidime for injecton, USP in sterile crystalline form is supplied in 6 gram Pharmacy Bulk Package bottles equivalent to 6 grams of anhydrous ceftazidime.
The Pharmacy Bulk Package bottle contains 708 mg of sodium carbonate. The sodium content is approximately 54 mg (2.3 mEq) per gram of ceftazidime.
The 6 g Pharmacy Bulk Package bottle is a container of sterile preparation for parenteral use that contains many single doses. The contents are intended for use in a pharmacy admixture program and are restricted to the preparation of admixtures for intravenous use. THE 6 g PHARMACY BULK PACKAGE IS NOT FOR DIRECT INFUSION. FURTHER DILUTION IS REQUIRED BEFORE USE.
