Ceftazidime for Injection) PHARMACY BULK PACKAGE – NOT for DIRECT INFUSION
PRESCRIBING INFORMATION FORTAZ® (ceftazidime for injection) PHARMACY BULK PACKAGE – NOT FOR DIRECT INFUSION To reduce the development of drug-resistant bacteria and maintain the effectiveness of FORTAZ and other antibacterial drugs, FORTAZ should be used only to treat or prevent infections that are proven or strongly suspected to be caused by bacteria. DESCRIPTION Ceftazidime is a semisynthetic, broad-spectrum, beta-lactam antibacterial drug for parenteral administration. It is the pentahydrate of pyridinium, 1-[[7-[[(2-amino-4 thiazolyl)[(1-carboxy-1-methylethoxy)imino]acetyl]amino]-2-carboxy-8-oxo-5-thia-1 azabicyclo[4.2.0]oct-2-en-3-yl]methyl]-, hydroxide, inner salt, [6R-[6α,7β(Z)]]. It has the following structure: The molecular 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. The Pharmacy Bulk Package vial contains 709 mg of sodium carbonate. The sodium content is approximately 54 mg (2.3mEq) per gram of ceftazidime. FORTAZ in sterile crystalline form is supplied in Pharmacy Bulk Packages equivalent to 6g of anhydrous ceftazidime. The 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 PHARMACY BULK PACKAGE IS NOT FOR DIRECT INFUSION, FURTHER DILUTION IS REQUIRED BEFORE USE. -

PRODUCT INFORMATION CEFTIN® Tablets (cefuroxime axetil tablets) CEFTIN® for Oral Suspension (cefuroxime axetil powder for oral suspension) DESCRIPTION: CEFTIN Tablets and CEFTIN for Oral Suspension contain cefuroxime as cefuroxime axetil. CEFTIN is a semisynthetic, broad-spectrum cephalosporin antibiotic for oral administration. Chemically, cefuroxime axetil, the 1-(acetyloxy) ethyl ester of cefuroxime, is (RS)-1-hydroxyethyl (6R,7R)-7-[2-(2-furyl)glyoxylamido]-3-(hydroxymethyl)-8-oxo-5- thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylate, 72-(Z)-(O-methyl-oxime), 1-acetate 3-carbamate. Its molecular formula is C20H22N4O10S, and it has a molecular weight of 510.48. Cefuroxime axetil is in the amorphous form and has the following structural formula: CEFTIN Tablets are film-coated and contain the equivalent of 125, 250, or 500 mg of cefuroxime as cefuroxime axetil. CEFTIN Tablets contain the inactive ingredients colloidal silicon dioxide, croscarmellose sodium, FD&C Blue No. 1 (250- and 500-mg tablets only), hydrogenated vegetable oil, hydroxypropyl methylcellulose, methylparaben, microcrystalline cellulose, propylene glycol, propylparaben, sodium benzoate (125-mg tablets only), sodium lauryl sulfate, and CEFTIN® Tablets (cefuroxime axetil tablets) CEFTIN® for Oral Suspension (cefuroxime axetil powder for oral suspension) titanium dioxide. CEFTIN for Oral Suspension, when reconstituted with water, provides the equivalent of 125 mg or 250 mg of cefuroxime (as cefuroxime axetil) per 5 mL of suspension. CEFTIN for Oral Suspension contains the inactive ingredients povidone K30, stearic acid, sucrose, and tutti-frutti flavoring. CLINICAL PHARMACOLOGY: Absorption and Metabolism: After oral administration, cefuroxime axetil is absorbed from the gastrointestinal tract and rapidly hydrolyzed by nonspecific esterases in the intestinal mucosa and blood to cefuroxime. -

There was minimal difference in overall wound infection rates between cefuroxime and amoxicillin+clavulanate group and side–effects in cefuroxime group were slightly less. Therefore, cefuroxime appears to be slightly more effective antibiotic for use as surgical prophylaxis. Keywords: Hernioplasty. Wound infection. Antibiotic prophylaxis. Surgical site infection Introduction Wound infection is very common problem worldwide. Surgical site Infections (SSI) are potential complications associated with any type of procedure and are among the most preventable hospital acquired infection. SSI effect on average 11% of patients undergoing a surgical procedure and second to third most frequent type of hospital acquired infection in US and Europe. At present, no country is free from the burden of diseases caused by HAI. Commonest causative organisms are staphylococci, streptococci etc. Antibiotics are used to prevent infection at surgical site. -
Empiric Antibiotic Therapy in Urinary Tract Infection in Patients with Risk
Bischoff et al. BMC Infectious Diseases (2018) 18:56 DOI 10.1186/s12879-018-2960-9 RESEARCH ARTICLE Open Access Empiric antibiotic therapy in urinary tract infection in patients with risk factors for antibiotic resistance in a German emergency department Sebastian Bischoff1, Thomas Walter2, Marlis Gerigk3, Matthias Ebert1 and Roger Vogelmann1* Abstract Background: The aim of this study was to identify clinical risk factors for antimicrobial resistances and multidrug resistance (MDR) in urinary tract infections (UTI) in an emergency department in order to improve empirical therapy. Methods: UTI cases from an emergency department (ED) during January 2013 and June 2015 were analyzed. Differences between patients with and without resistances towards Ciprofloxacin, Piperacillin with Tazobactam (Pip/taz), Gentamicin, Cefuroxime, Cefpodoxime and Ceftazidime were analyzed with Fisher’s exact tests. Results were used to identify risk factors with logistic regression modelling. Susceptibility rates were analyzed in relation to risk factors. Results: One hundred thirty-seven of four hundred sixty-nine patients who met the criteria of UTI had a positive urine culture. An MDR pathogen was found in 36.5% of these. Overall susceptibility was less than 85% for standard antimicrobial agents. Logistic regression identified residence in nursing homes, male gender, hospitalization within the last 30 days, renal transplantation, antibiotic treatment within the last 30 days, indwelling urinary catheter and recurrent UTI as risk factors for MDR or any of these resistances.ForpatientswithnoriskfactorsCiprofloxacinhad90%,Pip/taz88%, Gentamicin 95%, Cefuroxime 98%, Cefpodoxime 98% and Ceftazidime 100% susceptibility.

Each dose was given with 1 g probenecid. Of the 62 assessable patients who received ampicillin, two failed to respond to treatment. Of 67 assessable patients who received cefuroxime axetil, one failed to respond. Pencillinase producing strains of Neisseria gonorrhoeae were isolated from five patients; one received ampicillin and failed to respond, whereas the other four received cefuroxime axetil and three were cured. A single oral dose of 1 5 g cefuroxime axetil with 1 g probenecid seemed to be an effective treatment for acute gonococcal urethritis, especially for penicillin resistant strains.

1 Cephalosporins and Vancomycin
Alice Prince CEPHALOSPORINS AND VANCOMYCIN CEPHALOSPORINS These compounds are closely related in structure, mechanism of action, spectrum of activity and pharmacology to the penicillins. They are produced by fungi and synthetic modification. I. CHEMISTRY Contains 6-membered dihydrothiazine ring. Substitutions at position 3 generally affect pharmacology; substitutions at position 7 affect antibacterial activity, but this is not invariably true. 1 II. MECHANISM OF ACTION Cephalosporins are bactericidal. They inhibit enzymatic reactions necessary for stable bacterial cell walls by binding to PBPs. Bacterial cells must be growing. III.

MECHANISM OF RESISTANCE TO CEPHALOSPORINS A. Failure to reach receptor sites, permeability. B. Destroyed by β-lactamase. Some gram-negative bacteria produce large amounts of β- lactamase constitutively. C. Failure to bind to penicillin binding proteins, in gram negative and gram positive organisms. V. ANTIMICROBIAL ACTIVITY The cephalosporins have been grouped into "generations" corresponding to their development by the pharmaceutical industry in response to clinical needs. In general, the later generations of cephalosporins have greater gram-negative activity at the expense of gram-positive activity. A.
