Although cefazolin is a very widely used cephalosporin, few data are available regarding its activity against B. fragilis. Because levels in serum and tissue are higher and the half-life in serum is longer for cefazolin than for other cephalosporins 8 ; , its potential synergy with clavulanic acid and sulbactam should reflect both the peak levels achieved immediately after an infusion and the low levels of BLI as compared with those of cefazolin which exist at the end of the dosing interval. Even with maximum doses of clavulanic acid and sulbactam, the short half-life of these drugs in serum 1.25 to 1.5 h ; results in levels in blood of approximately 0.5 p.g ml or less at the trough of an 8-h dosing interval. For the most resistant strains MIC, 16 p.g of cefazolin component per ml ; , increasing the concentration of BLI eightfold from 0.5 to 4.0 , ug ml resulted in the inhibition of 4 of strains by sulbactam and 3 of 8 strains by clavulanic acid. A further doubling of the concentration of BLI did not make any difference. Higher concentrations are not only clinically difficult to achieve in serum and tissue but are also inhibitory by themselves. Thus, for most strains of B. fragilis in which cefazolin plus a BLI is likely to be an active combination, even the low concentration of BLI present at the end of the dosing interval should be synergistic for the inhibition of bacterial growth. The results of tests performed with a 4: 1 fixed ratio of cefazolin to BLI do not simulate the ratios predicted for.
Janice E. Contreras, Regis P. Kowalski, Francis S. Mah, Paul P. Thompson. The Charles T. Campbell Laboratory, University of Pittsburgh, Pittsburgh, PA. Purpose: To compare the in vitro susceptibility of cefuroxime, a 2 generation cephalosporin that is being used in Europe for prophylaxis as an intracameral injection, to moxifloxacin, gatifloxacin, and cefazolin 1st generation cephalosporin ; . Methods: The MICs were determined for 92 bacterial isolates from endophthalmitis Mather Study ; to cefuroxime and cefazolin using E-tests. The in vitro susceptibility profiles were compared statistically Monte-Carlo Randomization ; to the previously determined moxifloxacin and gatifloxacin susceptibility results determined from E-tests ; Mather Study ; . Results: The in vitro susceptibility profiles for the four antibiotics were statistically equivalent for Staphylococcus pneumoniae N 14 ; , Coagulase-Negative Staphylococcus N 20 ; , Streptococcus aureus N 10 ; , St viridans N 10 ; , Betahemolytic streptococcus N 5 ; , and Haemophilus N 4 ; . Moxifloxacin and gatifloxacin provided higher susceptibility to Bacillus N 9 ; , Enterococcus N 9 ; , and Gram-Negative Bacteria N 11 ; than cefuroxime and cefazolin. Against all isolates, the in vitro susceptibility profiles of cefuroxime and cefazolin were equivalent. Conclusion: This study suggests, that based on in vitro susceptibility testing using actual endophthalmitis isolates, moxifloxacin and gatifloxacin would provide wider antibacterial coverage than cefuroxime or cefazolin. While the debate over the efficacy of intracameral antibiotics for the prophylaxis of post operative endophthalmitis continues, fourth generation fluoroquinolones may provide more broad spectrum coverage of endophthalmitis causing bacteria than cefuroxime. Independent Study: No pharmaceutical support.

These drugs must include the legend: "CAUTION: Federal Law prohibits dispensing without prescription." Hence prescription drugs are often known as legend drugs. Detailed legislation regarding the writing and filling of prescriptions is the responsibility of the individual states. A special class of prescription drugs, comprising narcotics, hypnotics, and other substances liable to abuse, is subject to stricter regulation by the Drug Enforcement Administration DEA ; , a branch of the United States Department of Justice. Drugs regulated by the DEA are called controlled substances. Besides being licensed to practice medicine, a physician must have a narcotic license issued by the DEA to prescribe these. Drugs that may be purchased by the lay consumer without a prescription are called nonprescription drugs or over-the-counter OTC ; drugs. Sources of Pharmaceutical Terms It must be conceded at the outset that the range of processes by which brand names come into existence is so broad as to defy simple classification. Only the most elaborate breakdown could find convenient niches for brand names as various as Akineton Greek, `motionless' ; , a drug for parkinsonism; Nivea Latin, `snowy' ; , a skin moisturizer; Flagyl, an antimicrobial originally used against flagellate parasites; Marezine Latin mare `sea' or Spanish mareo `seasickness' ; , a drug for motion sickness; Marinol, another antinauseant, made from marijuana; Ocean, a saline nasal spray; Premarin, an estrogenic material derived from pregnant mares' urine; GoLYTELY, an isosmotic laxative; Tears Naturale, an artificial ocular lubricant; and Bugs Bunny Plus Iron Children's Chewable Vitamins Sugar Free ; . But despite this broad diversity, it is possible to identify a number of recurring patterns in the formation of pharmaceutical brand names. The semantic or lexical material on which most brand names are based comes from a fairly narrow range of sources: the chemical designation of the drug, usually its generic name cefazolin Kefzol; betamethasone valerate Valisone its pharmacologic action Surfak, a surfactant; Reglan, a regulator of gastrointestinal motility the state it is intended to induce or maintain Cylert, to improve alertness in attention deficit disorder; Tranxene, a tranquilizer the disease or condition it is meant to correct or mitigate Parlodel and Zelopar, drugs for parkinsonism; Condylox, for condylomata acuminata the administration form Amphojel, Cortifoam, Libritabs the dose Augmentin 875, Thiosulfil Forte the concentration Benzac 10, Humulin 70 30 the delivery characteristics Niaspan, Slo-Mag and the manufacturer's name Gilead Viread, Robins Robaxin ; . As the examples given above clearly show, a drug name is typically formed by abridgment of the source material, by alteration of its spelling, or by a combination of both processes. Abridgment Contraction of the generic name by the simple omission of certain letters is a common practice. This may consist in removing the beginning of the generic name and cefprozil.

Recent studies in our laboratories have shown that between 70 to 80% of cefazolin is bound by serum protein in dogs. Cephaloridine was 10% protein bound and cephalothin was 40% protein bound in the same dogs. It was also found that, soon after administration of cefazolin, levels were extremely high when compared to equivalent doses of cephaloridine and cephalothin. It was felt that the discrepancy between these two findings might in part by explained by differences in the rates at which antibiotics were bound to canine serum proteins. The following studies were performed to explore that possibility.

General Criteria for all PDL categories A: To apply to all categories with brand and generic versions on different sides of the PDL: Prior Authorizations for non-preferred brands or in certain cases non-preferred generic form -- 1. Requests will be approved for patients that show reduced objective outcomes on the preferred version relative to the non-preferred version. 2. Requests will be approved for patients experiencing side effects on the preferred generic version only if the side effect has not been reported in the literature for the brand version. The completion and submission of the medwatch form will then also be required. B: To apply to all requests for non-preferred brands and other drugs with PA conditions for non FDA approved indications. Decisions will be made on a case by case basis until the DUR committee is able to review the evidence and make a recommendation. Interim approvals and DUR recommendations for approval of a drug for a non FDA approved indication will require a minimum of two published, peer reviewed, non contradicted, double-blinded, placebo-controlled, randomized studies establishing both safety and efficacy. C: PDL drugs may also be affected by dose consolidation requirements. See list of limited drugs start on the last page of PDL. D: 1. The minimum trial periods for each preferred drug is two weeks, unless otherwise stated within specific PDL drug categories. 2. A trial will not be considered valid if non preferred products were readily available paid by override, cash, or samples ; . 3. Certain drug trials, such as with preferred narcotics, may require evidence that the preferred drugs were actually tried example: with urine drug tests ; . 4. Trials withl less than a two week duration will be reviewed on a case-by-case basis. E: Other Criteria: Drugs that must be submitted on specific prior authorization forms may contain additional criteria that has not been repeated below in this document.
