Introduction
|
|---|
Antibiotics are grouped into categories on the basis of their
mechanisms of action. These categories include cell-wall active
antibiotics, ribosomal active antibiotics, RNA active antibiotics,
DNA active antibiotics, antimetabolites, and the reducing compounds.
 |
Cell-Wall Active Antibiotics
|
|---|
The cell-wall active antibiotics include penicillins, β-lactamase
inhibitors, cephalosporins, other β-lactam antibiotics, and
vancomycin. β-lactamase inhibitors are combined with
the penicillins to enhance the antibiotic activity against β-lactamase-producing
organisms.
Penicillins
The penicillin class of antibiotics is frequently used for the
treatment of musculoskeletal infections. The penicillins can be
divided into general groups on the basis of their antibacterial
activity. The major penicillin groups of interest to an orthopaedic surgeon
are natural penicillins, aminopenicillins, penicillinase-resistant
penicillins, antipseudomonal penicillins (carboxypenicillins), and
extended spectrum penicillins (ureidopenicillins). There is overlap
among these groups; the differences are usually pharmacological
in nature.
The major side effects of all of the penicillins are hypersensitivity reactions
that range in severity from a rash to anaphylaxis1.
