Nifedipine 80-90 neuropeptide Y Homo sapiens 111-114 8606797-6 1995 The effects of NPY were additive with nifedipine (at a supramaximal concentration of 5 microM), suggesting that NPY predominantly inhibits N-type Ca2+ channels present in these cells, and not L-type. Nifedipine 38-48 neuropeptide Y Homo sapiens 112-115 2706916-2 1989 The effect of a single oral dose (10 mg capsule) of nifedipine on NPY- and NA-induced reductions of forearm blood flow (FBF) was studied in seven healthy volunteers. Nifedipine 52-62 neuropeptide Y Homo sapiens 66-69 2706916-0 1989 Effect of oral administration of nifedipine on neuropeptide Y- and noradrenaline-induced vasoconstriction in the human forearm. Nifedipine 33-43 neuropeptide Y Homo sapiens 47-61 2706916-3 1989 Intra-arterial infusions of NPY and NA into the brachial artery before nifedipine caused dose-dependent reductions in FBF with threshold doses of 0.2 and 0.03 nmol x min-1, respectively. Nifedipine 71-81 neuropeptide Y Homo sapiens 28-31 2706916-6 1989 The NPY-induced decrease in FBF was slightly but significantly attenuated after compared to before nifedipine (19 +/- 6 vs. 28 +/- 5% at 1.0 nmol NPY x min-1; P less than 0.01). Nifedipine 99-109 neuropeptide Y Homo sapiens 4-7 2461438-4 1988 The relaxant action of the calcium antagonist nifedipine on NPY-evoked contraction of cerebral arteries was not inhibited by a Ca++-deficient medium or by a high-Ca++ medium. Nifedipine 46-56 neuropeptide Y Homo sapiens 60-63 3595720-7 1987 Nifedipine and felodipine reduced the contractile response to both NA and NPY on renal and skeletal muscle arteries. Nifedipine 0-10 neuropeptide Y Homo sapiens 74-77 2468060-11 1988 Nifedipine slightly enhanced plasma NA and NPY-LI but not A during exercise. Nifedipine 0-10 neuropeptide Y Homo sapiens 43-46 3595720-12 1987 In conclusion, NPY exerts a potent nifedipine-sensitive vasoconstrictor activity, especially on human skeletal muscle arteries in vitro, although the influx of extracellular calcium may not be a crucial mechanism. Nifedipine 35-45 neuropeptide Y Homo sapiens 15-18 3595720-13 1987 The NPY-induced contractions of mesenteric veins and the inhibition of nerve-evoked [3H]NA efflux seem to be mediated via nifedipine resistant messenger systems. Nifedipine 122-132 neuropeptide Y Homo sapiens 4-7 3595720-9 1987 Nifedipine still inhibited the NPY contractions in a Ca2+-free medium while high extracellular Ca2+ (7.5 mM) partly reduced the nifedipine effect. Nifedipine 0-10 neuropeptide Y Homo sapiens 31-34 3595720-10 1987 NPY reduced the nerve stimulation-evoked [3H]NA overflow from the mesenteric veins via a nifedipine resistant mechanism. Nifedipine 89-99 neuropeptide Y Homo sapiens 0-3 3028044-0 1986 Neuropeptide Y constricts human skeletal muscle arteries via a nifedipine-sensitive mechanism independent of extracellular calcium? Nifedipine 63-73 neuropeptide Y Homo sapiens 0-14 3841402-8 1985 The calcium-entry antagonist nifedipine abolished both the NPY-induced contractions and the enhancement of NA-evoked contractions. Nifedipine 29-39 neuropeptide Y Homo sapiens 59-62 2455193-14 1987 Calcium antagonists such as nifedipine inhibit the vasoconstrictor actions of NPY on arteries, but not on veins. Nifedipine 28-38 neuropeptide Y Homo sapiens 78-81
