Analysis Note

These secondary standards offer multi-traceability to the USP, EP (PhEur) and BP primary standards, where they are available.

Application

These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.

Metformin hydrochloride may be used as a pharmaceutical reference standard for the quantification of the analyte in pharmaceutical formulations using different chromatography techniques.

Biochem/physiol Actions

Metformin is an antidiabetic agent that reduces blood glucose levels and improves insulin sensitivity. Its metabolic effects, including the inhibition of hepatic gluconeogenesis, are mediated at least in part by activation of the LKB1-AMPK (AMP-activated protein kinase) pathway. Activation of this pathway also appears to be involved in the antiproliferative and proapoptotic actions of metformin in cancer cell lines.

General description

Metformin is a biguanide hypoglycaemic agent and an oral antidiabetic medication widely used in the treatment of type 2 diabetes. It is effective in glycemic control and decreases the intestinal absorption of glucose, without the problem of serious lactic acidosis.

Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.
