Some bacteria produce beta lactamase enzyme, this enzyme will break the beta lactam ring structure of certain antibiotics (penicillin, cephalexin for example) rendering them ineffective against the infection. If you add a beta lactamase inhibitor to a beta lactam antibiotic (i.e clavulanaic acid added to amoxicillin) it decreases the potential of the bacteria to inactivate the antibiotic.

Which chemical inhibits beta lactamase enzymes?
Clavulanic acid is a potent inhibitor of beta-lactamase enzymes. It is often combined with certain antibiotics like amoxicillin to enhance their effectiveness by protecting them from degradation by beta-lactamase enzymes.
What is an example of a penicillin mixed with a beta-lactamase inhibitor?
The drug Augmentin, for example, contains a combination of amoxicillin and a betalactamase inhibitor, clavulanic acid.
What is a beta-lactamase?
A beta-lactamase is an enzyme produced by certain bacteria, which is responsible for their resistance to beta-lactam antibiotics.
What does AmpC stand for in the name AmpC beta-lactamase?
Ampicillin class C beta lactamase
What is co amoxilclav an what it is use for?
Co-amoxiclav is an approved British name for the combination antibiotic containing compounds such as amoxicillin trihydrate, a beta-lactam antibiotic, with potassium clavulanate, and a beta-lactamase inhibitor. The combination yields an antibiotic with an increased spectrum of action and restored efficacy against amoxicillin-resistant bacteria that produce beta-lactamase.
Is the drug ceftriaxone the same as unasyn?
No. Unasyn is the trade name for the combination of two generic drugs: ampicillin (a beta-lactam) and sulbactam (a beta-lactamase inhibitor). Ceftriaxone is a generic drug in another class of antibiotics altogether (cephalosporins).
Why are penicillins sometimes combined with beta-lactamase inhibitors?
Beta-lactamase inhibitors, protect the penicillin from bacterial enzymes that may destroy it before it can do its work.
What is the substitute drug for amoxcicillin?
If you are wondering what is the name of a drug that contains amoxicillin - one would be Augmentin. This is made of amoxicillin and clavulanate. Clavulanate is what is referred to as a 'beta lactamase inhibitor' and this allows amoxicillin to be effective against drug-resistant bacteria that produce beta lactamase. Words ending in -ase are generally enzymes that are going to break something down. The penicillin family of antibiotics are called 'beta lactams' due to their structure. Some bacteria have developed beta lactamase in order to break down these antibiotics, thereby becoming a drug-resistant bacteria.
What is Beta-lactamase positive?
Beta-lactamase-positive bacteria produce an enzyme called beta-lactamase which can inactivate beta-lactam antibiotics, such as penicillin, by breaking down the beta-lactam ring in the antibiotic molecule. This makes the bacteria resistant to beta-lactam antibiotics.
Is cepodoxime effective against Extended Species Beta Lactamase?
no
What is Clavubactin M?
Clavubactin M is the trade name of a veterinary formulation of clavulonic acid and amoxicillin; it is a penicillin-class drug combined with a beta-lactamase inhibitor that is intended for use in treating bacterial infections in companion animals.
Use of cefixime and clavulanic acid combination?
cefixime and clavulanic acid can be used as a second line therapy where cefixime alone is not able to show it's bacteriocidal activity. Cefixime comes under beta lactum antibiotic category and gets degrade inpresence of beta lactumase enzyme, bacterias have developed resistance against cefixime by producing beta lactamase and ESBLs. Clavulanic acid is an irreversible inhibitor of beta lactamase enzyme and have mild antibiotic activity. when this combination is used, clavulanic acid inhibits beta lactamase enzyme and allow cefixime work as a bacteriocidal. the combination is very useful against cefixime resistant becteria. more research work is required to understand the further use of this combination and also to find out the superiority of this combination over Amoxi+Clav combination.
