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 ...
Historically, the mole was defined as the amount of substance in 12 grams of the carbon-12 isotope.As a consequence, the mass of one mole of a chemical compound, in grams, is numerically equal (for all practical purposes) to the mass of one molecule or formula unit of the compound, in daltons, and the molar mass of an isotope in grams per mole is approximately equal to the mass number ...
[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 .
Therefore, the heat capacity of a sample of a solid substance is expected to be 3RN a, or (24.94 J/K)N a, where N a is the number of moles of atoms in the sample, not molecules. Said another way, the atom-molar heat capacity of a solid substance is expected to be 3 R = 24.94 J⋅K −1 ⋅mol −1 , where "amol" denotes an amount of the solid ...
Flucloxacillin has similar pharmacokinetics, antibacterial activity, and indications to dicloxacillin, and the two agents are considered interchangeable. It is reported to have higher, though rare, incidence of severe hepatic adverse effects than dicloxacillin, [ 28 ] but a lower incidence of renal adverse effects.
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.
