    Side effects

    Pharmacology

    Alclometasone induces the production of lipocortins, formally known as annexins, which inhibit phospholipase A2 – the enzyme responsible for the synthesis of arachidonic acid. Without the oxidation of arachidonic acid, eicosanoids, such as prostaglandins, thromboxanes, and leukotrienes, can't be produced.

    Alclometasone also inhibits the release of pro-inflammatory mediators from leukocytes (e.g., cytokines, histamine, leukotrienes, serotonin).
