Cloxacillin is an antibiotic useful for the treatment of several bacterial infections. [1] This includes impetigo , cellulitis , pneumonia , septic arthritis , and otitis externa . [ 1 ] It is not effective for methicillin-resistant Staphylococcus aureus (MRSA). [ 2 ]
Flucloxacillin, also known as floxacillin, is an antibiotic used to treat skin infections, external ear infections, infections of leg ulcers, diabetic foot infections, and infection of bone. [6] It may be used together with other medications to treat pneumonia, and endocarditis. [6]

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. Dicloxacillin is available under a variety of trade names including Diclocil . [2]
Penicillin resistance in Staphylococcus aureus [3] appeared very soon after penicillin entered general clinical use in 1943, and the mechanism of resistance was the production of β-lactamase. Modification of the penicillin molecule so that it was resistant to being broken down by β-lactamase was able to temporarily overcome this problem.
It is similar to methicillin, and has replaced methicillin in clinical use. Other related compounds are nafcillin, cloxacillin, dicloxacillin, and flucloxacillin. Since it is resistant to penicillinase enzymes, such as that produced by Staphylococcus aureus, it is widely used clinically in the US to treat penicillin-resistant Staphylococcus aureus.
It is relatively safe for use during pregnancy. [3] It is in the penicillin and beta lactam family of medications. [4] It usually results in bacterial death. [4] Phenoxymethylpenicillin was first made in 1948 by Eli Lilly. [5]: 121 It is on the World Health Organization's List of Essential Medicines. [6] It is available as a generic medication. [4]
The side effects of penicillin can be altered by taking other medications at the same time. Taking oral contraceptives along with penicillin may lower the effects of the contraceptive. When probenecid is used concurrently with penicillin, kidney excretion of probenecid is decreased resulting in higher blood levels of penicillin in the ...
