Morniflumate, given at therapeutic dosages to healthy human volunteers, on leukotriene B4 (LTB4) and thromboxane (TXB2) synthesis, both in purified PMNs (polymorphnuclear neutrophils) and in whole blood. In whole blood experiments, morniflumate reduced blood leukotriene B4 (LTB4) synthesis induced by Ca-ionophore A23187 Bx approximately 50%, both after a single dose and at steady state; the level of inhibition showed a pattern similar to the plasma levels of the bioactive metabolite of morniflumate (M1). The inhibition of serum thromboxane B2 (TXB2) levels was higher than 85%. Hence, morniflumate is demonstrated to reduce arachidonic acid metabolism, by exerting its effects on cyclooxygenase and 5-lipoxygenase. This characteristic might provide a better approach for anti-inflammatory therapy. In several animal models orally administered morniflumate, the beta-morpholinoethyl ester of niflumic acid, proved almost equal to the parent compound in anti-inflammatory, analgesic and antipyretic activity with the absence of gastric irritating/ulcerogenic effects of its acidic parent compound.

The primary mechanism of niflumic acid and its ester is action is inhibition of enzymes involved in the synthesis of inflammatory prostaglandins. This medication inhibits cyclooxygenase and 5-lipoxygenase pathways, which lead to fever and inflammation. Niflumic acid, a calcium-activated Cl- channel blocker, is an analgesic and anti-inflammatory agent used in the treatment of inflammatory conditions. Niflumic acid does directly inhibit calcium channels or activate potassium channels. Niflumic acid selectively reduces noradrenaline- and 5-HT-induced pressor responses by inhibiting a mechanism which leads to the opening of voltage-gated calcium channels. Niflumic acid (NFA) produces biphasic behavior on human CLC-K channels that suggests the presence of two functionally different binding sites: an activating site and a blocking site.
