2012-11-03 MEFOXIN ® (cefoxitin) For Injection. DESCRIPTION. MEFOXIN (cefoxitin for injection) is a semi-synthetic, broad-spectrum cepha antibiotic sealed under nitrogen for intravenous administration. It is derived from cephamycin C, which is produced by Streptomyces lactamdurans.Its chemical name is sodium (6R,7S)-3-(hydroxymethyl)-7-methoxy-8-oxo-7-[2-(2-thienyl) acetamido]-5-thia-1azabicyclo[4.2.0 Cefoxitin exhibits in vitro minimum inhibitory concentrations (MIC’s) of 8 μg/mL or less for aerobic microorganisms and 16 μg/mL or less for anaerobic microorganisms against most (≥ 90%) strains of the following microorganisms; however, the safety and effectiveness of cefoxitin in … [Tedizolid photo] KEY POINTS Tedizolid (Sivextro) is an oxazolidinone antibiotic that works by binding to the 50S ribosomal subunit in bacteria, which inhibits protein synthesis In vitro time-kill studies show tedizolid as bacteriostatic against Enterococci, Staphylococci, and Streptococci Has activity versus MRSA Lacks Gram negative or anaerobic coverage FDA-approved in June 2014 for acute If C. trachomatis is a suspected pathogen, appropriate anti-chlamydial coverage should be added, because cefoxitin sodium has no activity against this organism. This formulation of Cefoxitin for Injection USP, Pharmacy Bulk Package SmartPak® should not be used in patients who require less than the 1 gram dose of cefoxitin. Conclusions: This study confirms that cefoxitin as SAP for anaerobic bacteria should be avoided due to low coverage.

Cefoxitin (PDF Version)Antibiotic Class: Second-Generation Cephalosporin (2 nd generation cephamycin). Antimicrobial Spectrum: Staphylococcus aureus (methicillin susceptible), Coagulase negative Staphylococci, Streptococcus pneumoniae (penicillin susceptible), Streptococcus spp, Haemophilus influenzae, Moraxella catarrhalis, Neisseria meningitides, Neisseria gonorrhoeae, Enterobacteriaceae, E Anaerobic coverage is indicated in a variety of infectious processes, including but not limited to aspiration pneumonia, intra-abdominal infection, gynecologic infection, and diabetic foot ulcer infection. Cefoxitin Tigecycline has no activity against Pseudomonas aeruginosa, but for Acinetobacter it depends on local susceptibility data; Tigecycline is active against SPACE organisms, but for Proteus spp it depends on local susceptibility data Penicillins Carbapenems Pencillin V/G Chloramphenicol Amoxicillin/ampicillin Amoxicillin-clavulanate None of the 46 strains of anaerobic bacteria tested, including 26 strains of Bacteroides fragilis, showed tolerance (minimal bactericidal concentration/minimum inhibitory concentration ratio >32) to cefoxitin. – Cefoxitin 2 g IV Q 6 hours – Add anaerobic coverage with cesarean delivery Clindamycin 900 mg IV Q 8 hours Metronidazole 500 mg IV Q6-8 (if not breastfeeding) – PCN allergy: substitute ampicillin/gent with cephalosporin or ampicillin with vancomycin – LIMITED trials comparing antibiotic regimens !

The susceptibilities of 428 gram-negative and gram-positive anaerobes (including selected cefoxitin-resistant strains) to Bay y3118 (a new fluoroquinolone), ciprofloxacin, clindamycin, metronidazole, cefoxitin, piperacillin, and piperacillin-tazobactam were tested. Organisms comprised 115 Bacteroide … The optimal choice of a cephalosporin is not clear. While cefoxitin has better anaerobic coverage, ceftriaxone has better coverage against N. gonorrhoeae. Follow-up includes evaluation by a health-care provider within 3 days to insure clinical improvement. Lack of improvement might require hospitalization, additional tests, or surgical intervention. Cefoxitin exhibits in vitro minimum inhibitory concentrations (MIC's) of 8 µg/mL or less for aerobic microorganisms and 16 µg/mL or less for anaerobic microorganisms against most (≥ 90%) strains of the following microorganisms; however, the safety and effectiveness of cefoxitin in treating clinical infections due to these microorganisms have not been established in adequate and well-controlled clinical trials. Cefoxitin was more active than cefotetan, particularly against non- B. fragilis species, Eubacterium spp.

Apr 4, 2021 II. Coverage Coverage. Cefoxitin (Mefoxin) 1-2 grams IM or IV every 6-8 hours; Cefotetan (Cefotan) 1-2 of both aerobic and anaerobic gram-positive and gram -negative microorganisms. Ontology: Cefoxitin (C0007557 Anaerobic+bacteria species are relatively often recovered from female genital involve cross-resistance to cefoxitin and β-lactamase inhibitor combinations. Sep 5, 2013 To collect recent data on the susceptibility of anaerobes to antimicrobial only 71% were susceptible to moxifloxacin and 79% to cefoxitin. the isolation by culture of anaerobic bacteria from clinical specimens may The in vitro susceptibility of 155 strains of anaerobic bacteria to five cephalosporin antibiotics was tested.

toward these pathogens.7,8 Anaerobic coverage is indicated if tubo-ovarian abscess is present. The Centers for Disease Control and Prevention (CDC) guidelines do not recommend double anaerobic coverage, and no evidence exists to show that double anaerobic coverage in PID results in better clinical or microbiologic cure rates.

True. b. False. 2. Early and aggressive use of antibiotics is the standard treatment for PID. Which treatment regimen is used for outpatient management? Cefotetan is an injectable antibiotic of the cephamycin type for prophylaxis and treatment of bacterial infections. It is often grouped together with second-generation cephalosporins and has a similar antibacterial spectrum, but with additional anti-anaerobe coverage.
