title: Inhibition by indomethacin and niflumic acid of catecholamine--uptake into rat hypothalamic and striatal synaptosomes.
abstract: Niflumic acid and indomethacin showed to be inhibitors of catecholamine--uptake into rat striatal and hypothalamic synaptosomes. Whereas the inhibition by niflumic acid was non-competitive for both amines at similar Ki values, the action of indomethacin displayed differences between areas as well as amines: the potency of inhibition by indomethacin was greater in striatal than in hypothalamic synaptosomes irrespective of the amine; the type of inhibition by indomethacin was non-competitive for norepinephrine, but competitive for dopamine regardless of the brain area.
