General description
Potassium clavulanate is an oxapenam derivative and belongs to the group of β-lactamase inhibitors. It is used in combination with the penicillin group of antibiotics to give them resistance to β-lactamase.
Application
The analytical standard can be used as follows:
- Simultaneous analysis of amoxicillin and clavulanate potassium in pharmaceutical formulations by capillary electrophoresis (CE) combined with capacitively coupled contactless conductivity detection (C4D)
- Development of a stability-indicating high-performance liquid chromatographic (HPLC) method combined with mass spectrometry (MS) to measure amoxicillin, clavulanate potassium, and their impurities in their combined dosage forms
- Residue analysis of potassium clavulanate and amoxicillin trihydrate by a UV spectrophotometric method in their bulk, combined tablet formulations, and human urine samples
- HPLC method-based determination of meropenem and potassium clavulanate in the presence of their degradation impurities in intravenous solutions in combination with a diode array detector (DAD)
- Determination of amoxicillin and clavulanic acid by capillary zone electrophoresis (CZE) in their combined commercial formulations
Biochem/physiol Actions
β-lactamase inhibitor, typically added to amoxicillin to increase its effectiveness.

Studies have shown that multiple genes influence antibiotic susceptibility, but the relationship between genotypic and phenotypic antibiotic susceptibility is unclear. We sought to analyze the concordance between the presence of antibiotic resistance (ABR) genes and antibiotic susceptibility results in urine

Inhibitor resistant (IR) class A β-lactamases pose a significant threat to many current antibiotic combinations. The K234R substitution in the SHV β-lactamase, from Klebsiella pneumoniae , results in resistance to ampicillin/clavulanate. After site-saturation mutagenesis of Lys-234 in SHV, microbiological and
