1,1-Dimetilbiguanida hydrochloride

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.

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.

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.

La metformina es un antidiabético que reduce las concentraciones de glucosa en sangre y mejora la sensibilidad a la insulina. Sus efectos metabólicos, entre ellos la inhibición de la gluconeogénesis hepática, están mediados al menos en parte por la activación de la ruta LKB1-AMPK (proteína cinasa activada por AMP). La activación de esta vía también parece estar implicada en las acciones antiproliferativas y proapoptóticas de la metformina en las líneas de células cancerosas.

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