Cloxacillin
Encyclopedia
Cloxacillin is a semisynthetic antibiotic
in the same class as penicillin
. Cloxacillin was discovered and developed by Beecham
. It is sold under a number of trade names, including Cloxapen, Cloxacap, Tegopen and Orbenin.
Cloxacillin is used against staphylococci that produce beta-lactamase
, due to its large R chain, which does not allow the beta-lactamases to bind.
This drug has a weaker antibacterial activity than benzylpenicillin
, and is devoid of serious toxicity except for allergic reactions.
It has been suggested, in one study, that increased use of cloxacillin may permit reduced use of vancomycin
.

Beta-lactamase
Beta-lactamases are enzymes produced by some bacteria and are responsible for their resistance to beta-lactam antibiotics like penicillins, cephamycins, and carbapenems . These antibiotics have a common element in their molecular structure: a four-atom ring known as a beta-lactam...
