Pharmacokinetics and Safety of Cefazolin 2g in DUPLEX

2014-08-27 03:13:47 | BioPortfolio


The purpose of this study is to demonstrate the safety and pharmacokinetics of Cefazolin 2g for Injection USP and Dextrose Injection USP in the DUPLEX® Drug Delivery System to Cefazolin 1.5g for Injection USP and Dextrose Injection USP in daily doses of 6g in healthy adult subjects for 11 days of administration.


B. Braun Medical Inc. intends to conduct human PK studies and obtain marketing approval for Cefazolin 2g in the United States with identical indications of those already approved for the 1g strength. A pharmacokinetic study will be conducted with the Cefazolin 2g product manufactured by B. Braun Medical Inc. Cefazolin 1.5g dose will be prepared using 10g Cefazolin pharmacy bulk with 5% Dextrose. The clinical study proposed in this protocol is designed to evaluate the pharmacokinetic characteristics of 2g and 1.5g Cefazolin in Dextrose in healthy subjects at the maximum recommended infusion dose of 6g per day per FDA's recommendation.

The study is designed to simulate clinical practice and overall experience with cephalosporin administration. Cefazolin may be reconstituted with dextrose (or a number of other diluents as recommended in the innovator's package insert) in order to achieve an osmolality appropriate for intravenous infusion.

According to B. Braun's approved package insert for Cefazolin 1g, the maximum dose of 1.5g Cefazolin for Injection USP and Dextrose Injection USP is 1.5 grams every 6 hours for severe, life-threatening infections. In rare instances, doses of up to 12 grams of Cefazolin per day have been used. Lower doses are stated in the B. Braun package insert.

Medical and Biotech [MESH] Definitions

Adverse reactions that occur initially at the site of injection or infusion. Milder type is confined to a local allergic flare reaction. A more severe reaction is caused by extravasation of VESICANTS from the blood vessel at the site of injection and can cause damage to the surrounding tissue. In tumor flare reaction symptoms involve well beyond the injection site such as an increase in the tumor size and tumor markers levels, bone pain, and HYPERCALCEMIA.

A semisynthetic cephalosporin analog with broad-spectrum antibiotic action due to inhibition of bacterial cell wall synthesis. It attains high serum levels and is excreted quickly via the urine.

Total or subtotal destruction of the pituitary gland by chemical injection. It is usually achieved by injection of ethyl alcohol via trans-sphenoidal cannulation under stereotaxic control. It is usually performed for the treatment of intractable pain.

Hemorrhagic necrosis that was first demonstrated in rabbits with a two-step reaction, an initial local (intradermal) or general (intravenous) injection of a priming endotoxin (ENDOTOXINS) followed by a second intravenous endotoxin injection (provoking agent) 24 h later. The acute inflammation damages the small blood vessels. The following intravascular coagulation leads to capillary and venous THROMBOSIS and NECROSIS. Shwartzman phenomenon can also occur in other species with a single injection of a provoking agent, and during infections or pregnancy. Its susceptibility depends on the status of IMMUNE SYSTEM, coagulation, FIBRINOLYSIS, and blood flow.

The analysis of a chemical substance by inserting a sample into a carrier stream of reagent using a sample injection valve that propels the sample downstream where mixing occurs in a coiled tube, then passes into a flow-through detector and a recorder or other data handling device.
