Dicloxacillin is a narrow-spectrum β-lactam antibiotic of the penicillin class. [1] It is used to treat infections caused by susceptible (non-resistant) Gram-positive bacteria . [ 1 ] It is active against beta-lactamase -producing organisms such as Staphylococcus aureus , which would otherwise be resistant to most penicillins .
The production of a β-lactamase by a bacterium does not necessarily rule out all treatment options with β-lactam antibiotics. In some instances, β-lactam antibiotics may be co-administered with a β-lactamase inhibitor. For example, Augmentin (FGP) is made of amoxicillin (a β-lactam antibiotic) and clavulanic acid (a β-lactamase inhibitor).
The two types of beta-lactamases work on the basis of the two basic mechanisms of opening the β-lactam ring. [2] The SBLs are similar in structure and mechanistically to the β-lactam target penicillin-binding proteins (PBPs) which are necessary for cell wall building and modifying. SBLs and PBPs both covalently change an active site serine ...
[3] [4] A number of natural penicillins have been discovered, but only two purified compounds are in clinical use: penicillin G (intramuscular or intravenous use) and penicillin V (given by mouth). Penicillins were among the first medications to be effective against many bacterial infections caused by staphylococci and streptococci .
Antibiotics (or, more properly, antibacterial drugs) are drugs used to kill bacteria; they can have side effects or even cause adverse reactions in people, however they are not classified as toxins. In a synecological , true-to-nature situation in which more than one bacterial species is present, the growth of microbes is more dynamic and ...
Cefixime, sold under the brand name Suprax among others, is an antibiotic medication used to treat a number of bacterial infections. [5] These infections include otitis media, strep throat, pneumonia, urinary tract infections, gonorrhea, and Lyme disease. [5] For gonorrhea typically only one dose is required. [6]
Ceftaroline has also been described as "fifth-generation" cephalosporin, but does not have the activity against Pseudomonas aeruginosa or vancomycin-resistant enterococci that ceftobiprole has. [36] Ceftolozane is an option for the treatment of complicated intra-abdominal infections and complicated urinary tract infections.
Initiation of post-exposure prophylaxis with the use of antiretroviral drugs is dependent on a number of risk factors, though treatment is usually started after one high-risk event. In order to determine whether post-exposure prophylaxis is indicated, an evaluation visit will be conducted to consider risk factors associated with developing HIV.
