Oral Beta-Lactam Antibiotics

What are common beta-lactam antibiotics?

Oral Beta-Lactam Antibiotics

Class Drug
Beta-lactam–beta-lactamase inhibitor combination Amoxicillin-clavulanate (Augmentin)
Antipseudomonal penicillin Carbenicillin (Geocillin)
First-generation cephalosporin Cefadroxil (Duricef)
Cephalexin (Keflex)

How many beta lactamases are there?

There are nine Class A β-lactamases, three Class C β-lactamases, a Class D β-lactamase, a Class B β-lactamase, and TII2115 protein. Cluster 2 is formed by 20 nodes: 14 PBPs, four Class A β-lactamases, a Class C β-lactamase, and OXA-23 from Class D β-lactamases.

Is Augmentin a beta-lactam?

For example, Augmentin (FGP) is made of amoxicillin (a β-lactam antibiotic) and clavulanic acid (a β-lactamase inhibitor). The clavulanic acid is designed to overwhelm all β-lactamase enzymes, and effectively serve as an antagonist so that the amoxicillin is not affected by the β-lactamase enzymes.

Is Augmentin bactericidal or bacteriostatic?

Amoxicillin and clavulanate (Augmentin) As a beta-lactam antibiotic, amoxicillin is mainly bactericidal. Inhibits third and final stage of bacterial cell wall synthesis by preferentially binding to specific PBPs located inside the bacterial cell wall.

What are some examples of macrolides?

Macrolides are a class of antibiotic that includes erythromycin, roxithromycin, azithromycin and clarithromycin. First-line indications for macrolides include the treatment of atypical community acquired pneumonia, H. Pylori (as part of triple therapy), chlamydia and acute non-specific urethritis.

Where are B lactamases found?

Although TEM-type β-lactamases are most often found in E. coli and K. pneumoniae, they are also found in other species of gram-negative bacteria with increasing frequency.

Which antibiotics are bactericidal?


  • Aminoglycosides: Tobramycin, gentamicin, amikacin.
  • Beta-lactams (penicillins, cephalosporins, carbapenems): Amoxicillin, cefazolin, meropenem.
  • Fluoroquinolones: Ciprofloxacin, levofloxacin, moxifloxacin.
  • Glycopeptides: Vancomycin.
  • Cyclic Lipopeptides: Daptomycin.
  • Nitroimidazoles: Metronidazole.

What can bacteria produce beta lactamase?

Beta-lactamases are enzymes produced by bacteria that break open the beta-lactam ring, inactivating the beta-lactam antibiotic. Some beta-lactamases are encoded on mobile genetic elements (eg, plasmids); others are encoded on chromosomes. There are numerous different types of beta-lactamases.

What is a good substitute for amoxicillin?

Seven best natural antibiotics. Garlic may be an effective treatment against bacteria.

  • Risks of natural antibiotics. Just because something is labeled natural,it is not necessarily safe.
  • When to use prescribed antibiotics. Antibiotics may be prescribed to speed recovery from illness or to prevent the spread of infectious diseases.
  • Outlook.
  • What drug class is antibiotic?

    Based on Drug Class, the Zoonotic Disease Treatment Market was studied across Antibacterial Medication and Antibiotics. Based on Disease Type, the Zoonotic Disease Treatment Market was studied

    How many classifications do antibiotics have?

    The first penicillin gave rise to an entire class of antibiotics known as penicillins. Penicillins are derived from a specific mold (a type of fungi)— Penicillium.

  • Cephalosporins are related to penicillins. They both belong to a larger class called beta lactams.
  • Macrolides are a completely different class of antibiotics from the beta lactams.
