What is a role of beta lactamase inhibitor?
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.

What is beta-lactamase?
Beta lactamase is an enzyme, which is produced by some bacteria. This enzyme brakes the beta lactum ring that is present in beta lactum antibiotics. You have four groups in beta-lactum antibiotics. They are penicillins, cephalosporins, monobactums and carbapenems. So you naturally have the enzymes penicillinase, cephalospoinase, monobactamase and carbapenamase. Whether they are one and the same enzyme or four different enzymes is not clear to the contributor and needs comment by expert in this field.
Asked in Medication and Drugs, Antibiotics, Amoxicillin
Is amoxicillin the same as augmentin?
Not exactly. Augmentin contains Amoxicillin and another drug, clavulonic acid. The latter augments the antimicrobial spectrum of Amoxicillin. Amoxicillin is a penicillin-like drug effective against certain types of bacteria, unless those baceria possess the enzyme that can inactivate these types of antibiotics. This enzyme is called beta-lactamase. Some bacteria have the ability to make beta-lactamase and some do not; some bacteria can develop the ability to make beta-lactamase if exposed to penecillin-like drugs over a period of time (one way bacterial develop resistance to antibiotics). Clavulonic acid blocks beta-lactamase, allowing the amoxicillin to work on bacteria whether or not they possess 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.
What alternative medication contains amoxicillin?
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 the difference between amoxicillin an cloxicillin?
They are both lactam containing antibiotics, like penicillin, but they differ in the size of the R groups attached to the alpha site of the lactam ring. The larger R group on cloxicillin keeps beta-lactamase from attaching, making it a superior antibiotic to amoxicillin, which is very susceptible to beta-lactamase, in the absence of a beta-lactamase inhibitor such as clavulanic acid. To my knowledge, cloxicillin is not widely used in medicine. This is due to broader spectrum antibiotics taking its place, such as vancomycin.

How do beta blockers and ACE inhibitors affect tattooing?
Beta blockers and ACE inhibitors have an affect on people's experiences during tattooing. For instance, people on beta blockers and ACE inhibitors report not being able to sit for tattoos as long as they would like. Additionally, it decreases people's threshold for pain, making the tattoo experience less pleasurable.
What do Ampicillin amoxicillin mezlocillin and penicillin G have in common?
Asked in Medication and Drugs
What pill has the letters AMC on it?
Pill imprint AMC has been identified as Amoxicillin. Amoxicillin is used in the treatment of urinary tract infection; upper respiratory tract infection; bacterial infection; bronchitis; kidney infections (and more), and belongs to the drug class beta-lactamase inhibitors. There is no proven risk in humans during pregnancy.

What is an example of a penicillin mixed with a beta-lactamase inhibitor?
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.
