Cefodizime is a 3rd generation cephalosporin antibiotic with broad spectrum activity against aerobic gram positive and gram negative bacteria. Clinically, it has been shown to be effective against upper and lower respiratory tract infections, urinary tract infections, and gonorrhea. Cefodizime is a bactericidal antibiotic that targets penicillin-binding proteins (PBPs) 1A/B, 2, and 3 resulting in the eventual death of the bacterial cell. In vivo experimental models of infection showed that bacterial clearance by this drug is at least as effective compared with other 3rd generation cephalosporins. It has similar adverse effect profile to other 3rd generation cephalosporins as well, mainly being limited to gastrointestinal or dermatological side effects.^[1]

Efficacy and susceptibility

Cefodizime demonstrated superior clinical efficacy that what could be predicted from its in vitro experimental results. Certain immunomodulatory properties of the drug might account for its increased in vivo activity against specific bacterial species. These immunomodulatory properties stimulate some phagocyte and lymphocyte cellular functions when they have been impaired.^[1] It was shown in a 2004 study that cefodizime increased expression of toll-like receptor 4 (TLR-4) in neutrophils stimulated by Klebsiella pneumoniae infection which then affected the production of cytokines in the stimulated cells.^[2] A 1992 study conducted in vitro susceptibility studies for cefodizime and found that gram negative bacteria with consistent susceptibility include: Enterobacteriaceae including E. coli , K. pneumoniae, Morganella morganii , Proteus mirabilis , P. vulgaris , Shigella sonnei , Yersinia enterocolitica , Salmonella , Haemophilus influenzae , Moraxella catarrhalis , Neisseria gonorrhoeae , and Neisseria meningitidis . In vitro susceptible gram positive bacteria include: methicillin-sensitive Staphylococcus aureus, and Streptococcus agalactiae , S. pneumoniae and S. pyogenes . Cefodizime was shown to be ineffective in vitro against Enterobacter spp. , Pseudomonas aeruginosa , and Xanthomonas maltophilia . Gram positive bacteria it was inactive against include Staphylococcus epidermidis and methicillin-resistant Streptococcus aureus . In this trial, bacteria were considered susceptible if 90% or more of the strains were inhibited by cefodizime concentrations of at least 8 mg/L in vitro.^[1]

Pharmacokinetics

Intramuscular cefodizime bioavailability ranges from 90% to 100%. It distributes into many tissues and is approximately 81% bound to plasma proteins, chiefly albumin. The drug reaches minimum inhibitory concentrations approximately 2–3 hours after administration, maintaining it for several hours afterwards. Clearance of cefodizime from the body is predominantly renal, with the majority of the drug excreted unchanged within the first 12 hours. More specifically, cefodizime is mainly cleared via glomerular filtration in the kidney, in addition to some tubular secretion. In patients with normal renal function, the terminal phase elimination half-life is approximately 3.5 hours.^[1]

Adverse effects

Cefodizime has been shown to be generally well tolerated in drug trials and its adverse effects are mainly gastrointestinal or dermatological. Gastrointestinal adverse effects were observed in 2.4% of patients during clinical trials and included: diarrhea, nausea, vomiting, and elevated transaminases. Allergic symptoms were observed in 1.1% of patients and include: exanthema, urticaria, and pruritus. Other adverse effects observed include local site reactions, pain at site of injection, and phlebitis.^[1]

Administration

Cefodizime is available as an intramuscular injection or as an intravenous bolus or infusion and is usually given 1 or 2 times a day. In clinical trials, the most frequently used adult dosages ranged from 2 grams to 4 grams IM or IV per day given as a single dose or in 2 divided doses.^[1]

Tigecycline, sold under the brand name Tygacil, is an tetracycline antibiotic medication for a number of bacterial infections. It is a glycylcycline administered intravenously.

As a tetracycline derivative antibiotic, its structural modifications has expanded its therapeutic activity to include Gram-positive and Gram-negative organisms, including those of multi-drug resistance.

Carbapenems are a class of very effective antibiotic agents most commonly used for the treatment of severe bacterial infections. This class of antibiotics is usually reserved for known or suspected multidrug-resistant (MDR) bacterial infections. Similar to penicillins and cephalosporins, carbapenems are members of the beta lactam class of antibiotics, which kill bacteria by binding to penicillin-binding proteins, thus inhibiting bacterial cell wall synthesis. However, these agents individually exhibit a broader spectrum of activity compared to most cephalosporins and penicillins. Furthermore, carbapenems are typically unaffected by emerging antibiotic resistance, even to other beta-lactams.

Ampicillin/sulbactam is a fixed-dose combination medication of the common penicillin-derived antibiotic ampicillin and sulbactam, an inhibitor of bacterial beta-lactamase. Two different forms of the drug exist. The first, developed in 1987 and marketed in the United States under the brand name Unasyn, generic only outside the United States, is an intravenous antibiotic. The second, an oral form called sultamicillin, is marketed under the brand name Ampictam outside the United States, and generic only in the United States. Ampicillin/sulbactam is used to treat infections caused by bacteria resistant to beta-lactam antibiotics. Sulbactam blocks the enzyme which breaks down ampicillin and thereby allows ampicillin to attack and kill the bacteria.
