Analysis Note

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

Application

Verapamil hydrochloride may be used as a pharmaceutical reference standard for the determination of the analyte in drug raw material and pharmaceutical formulations by high performance liquid chromatography and spectrophotometric method, respectively.

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.

Biochem/physiol Actions

α₁-adrenoceptor antagonist; L-type calcium channel blocker. Blocks L-type Ca²⁺ channels in smooth and cardiac muscle, induces apoptosis of human primary and metastatic colon adenocarcinoma cells in vitro. Drug resistance reversal agent acting on Pgp, e.g. decrease renal tubule elimination of digoxin. Increases basal ATPase activity of Pgp. Substrate of Cyp3A4 and CYP2C6.
