Nifedipine-d6 is intended for use as an internal standard for the quantification of nifedipine by GC- or LC-MS. Nifedipine is a dihydropyridine L-type calcium channel blocker that reduces the amplitude of spontaneous contractions in isolated rabbit ileum when used at a concentration of 1 μM. Nifedipine (1 μM) reduces TGF-β-induced calcium oscillations in human fibroblasts and prevents impairment of lung function in a mouse model of pulmonary fibrosis induced by bleomycin when administered at a dose of 10 mg/kg per day. It also reduces increases in mean arterial blood pressure induced by angiotensin II in spontaneously hypertensive rats when administered at a dose of 10 μg/kg. Formulations containing nifedipine have been used in the treatment of hypertension and angina.

Highly sensitive and rapid ultra-performance liquid chromatography-tandem mass spectrometry method for the determination of nifedipine in human plasma and its application to a bioequivalence study
Biomed Chromatogr 2012 Dec;26(12):1509-18.PMID:22383257DOI:10.1002/bmc.2725
An ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method has been developed for the determination of nifedipine in human plasma using Nifedipine-d6 as the internal standard (IS). The plasma samples were prepared by solid-phase extraction on Phenomenex Strata-X cartridges employing 200 μL human plasma. Chromatography was carried out on Waters Acquity UPLC BEH C₁₈ (50 × 2.1 mm, 1.7 µm particle size) analytical column under isocratic conditions using a mobile phase consisting of 4.0 mm ammonium acetate-acetonitrile (15:85, v/v). The precursor → product ion transitions for nifedipine (m/z 347.2 → 315.2) and IS (m/z 353.1 → 318.1) were monitored on a triple quadrupole mass spectrometer, operating in the multiple reaction monitoring and positive-ion mode. The method was validated over a wide dynamic concentration range of 0.050-150 ng/mL. Matrix effect was assessed by post-column analyte infusion and the mean extraction recovery was 95.6% across four quality control levels. The method is rugged and rapid with a total run time of 1.2 min and was applied to a bioequivalence study of 20 mg nifedipine tablet formulation in 30 healthy Indian subjects under fasting condition. Assay reproducibility was confirmed by reanalysis of 116 incurred samples.
