概要
低力価の局所用コルチコステロイドと見なされており、局所的なそう痒性および/または炎症性疾患の補助治療に有用です。高力価のステロイドと比較してリスクが低いため、特に広範囲や小型の患者に対する最初の選択肢として適しています。
作用機序
Corticosteroids are non-specific anti-inflammatory agents. They act by inducing phospholipase A2 inhibitory proteins (lipocortins) in cells → reducing the formation, activity, and release of endogenous inflammatory mediators (e.g., histamine, prostaglandins, kinins).
They also reduce DNA synthesis via an anti-mitotic effect on epidermal cells and inhibit the migration of leukocytes and macrophages to the area, reducing erythema, pruritus, and edema.

薬物動態
吸収
Systemic absorption is rare but possible with long-term use over large areas.
過剰投与
Overdose via topical application is unlikely, but chronic overuse can lead to iatrogenic hyperadrenocorticism (Cushing's syndrome) and HPA axis suppression.
