Nine patients with severe coronary artery disease and disabling angina receiving either regular metoprolol or oxprenolol, together with glyceryl trinitrate tablets as required for chest pain, were studied. Nifedipine 10 mg three times per day was compared to placebo in a double blind randomized control trial, using patient diary cards and exercise tests. The number of recorded episodes of angin...
AIMS Nafcillin (Wyeth Laboratories, Philadelphia, PA, USA) has been reported to induce the metabolism of cyclosporin and warfarin, which are known substrates of cytochrome P-450 (CYP). However, there has not been any report to date on its possible interaction with nifedipine, an index substrate of the enzyme, CYP3A4. METHODS Nine healthy normotensive subjects participated in this randomized p...
Baicalin purified from the root of Radix scutellariae is widely used in clinical practices. This study aimed to evaluate the effect of baicalin on the pharmacokinetics of nifedipine, a CYP3A probe substrate, in rats in vivo and in vitro. In a randomised, three-period crossover study, significant changes in the pharmacokinetics of nifedipine (2 mg/kg) were observed after treatment with a low (0....
To characterize Ca(2+) transport in newborn rat cortical collecting duct (CCD) cells, we used nifedipine, which in adult rat distal tubules inhibits the intracellular Ca(2+) concentration ([Ca(2+)](i)) increase in response to hormonal activation. We found that the dihydropyridine (DHP) nifedipine (20 microM) produced an increase in [Ca(2+)](i) from 87.6 +/- 3.3 nM to 389.9 +/- 29.0 nM in 65% of...
Context Previous case reports have documented the effectiveness of l-type calcium channel blockers (such as nifedipine and verapamil) for treating different forms of hyperinsulinemic hypoglycemia (HH). Objective To systematically assess the glycemic response to nifedipine therapy in 11 patients with HH due to mutations in the ABCC8 gene. Design Dose escalation of nifedipine therapy. Setti...
