Description

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.
