“ Azelnidipine inhibited it most potently among the Ca2+-channel blockers tested (azelnidipine, amlodipine, nifedipine, diltiazem, verapamil, and nicardipine) at … concentration of 10 μM. Longer stimulation with these agents induced the expression of inducible nitric oxide synthase and nitrotyrosine , with an increase of lactic dehydrogenase …, whereas azelnidipine suppressed these changes.”
“ Azelnidipine may inhibit nitrotyrosine expression and cell damage caused by overproduction of nitric oxide, suggesting a mechanism for its cardiovascular protective effect.”
