Amoxicillin is an antibiotic while clavulanic acid is a non-antibiotic β-lactamase inhibitor which prevents metabolism of amoxicillin by certain bacteria. In addition to its β-lactamase inhibition, clavulanic acid shows central nervous system actions and effects and has been studied in the potential treatment of various psychiatric and ...
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. Another β-lactam/β-lactamase inhibitor ...

This is a list of common β-lactam antibiotics—both administered drugs and those not in clinical use—organized by structural class.
This means that individual antibiotics that used to be effective are no longer effective, [1] and because of the absence of new classes of antibiotic, they allow old antibiotics to be continue to be used. [2] In particular, they may be required to treat multiresistant organisms, [1] [2] such as carbapenem-resistant Enterobacteriaceae. [3]
Amoxicillin (α-amino-p-hydroxybenzyl penicillin) is a semisynthetic derivative of penicillin with a structure similar to ampicillin but with better absorption when taken by mouth, thus yielding higher concentrations in blood and in urine. [58] Amoxicillin diffuses easily into tissues and body fluids.
The effectiveness of auxiliary labels can vary greatly between different label formats and specific text, with a 2006 survey finding that one common multi-step, complex label ("Do not take dairy products, antacids, or iron preparations within 1 hour of this medication") was interpreted correctly only 7.6% of the time.
In areas of low clarithromycin resistance, including the United States, a 14-day course of "triple therapy" with an oral proton pump inhibitor, clarithromycin 500 mg, and amoxicillin 1 g (or, if penicillin allergic, metronidazole 500 mg), all given twice daily for 14 days, is recommended for first-line therapy. This regimen can achieve rates of ...
Currently marketed β-lactamase inhibitors are not sold as individual drugs. Instead they are co-formulated with a β-lactam antibiotic with a similar serum half-life. This is done not only for dosing convenience, but also to minimize resistance development that might occur as a result of varying exposure to one or the other drug.
