Topical steroids are the topical forms of corticosteroids. Topical steroids are the most commonly prescribed topical medications for the treatment of rash, eczema, and dermatitis. Topical steroids have anti-inflammatory properties, and are classified based on their vasoconstriction abilities. There are numerous topical steroid products. All the preparations in each class have the same anti-inflammatory properties, but essentially differ in base and price. Over the past decade, much awareness has been brought to the side effects and damage that long term topical steroid use can bring, particularly in cases where it used for the treatment of eczema.〔(【引用サイトリンク】title=Side effects of topical steroids: A long overdue revisit )〕 == Medical uses == Weaker topical steroids are utilized for thin-skinned and sensitive areas, especially areas under occlusion, such as the armpit, groin, buttock crease, breast folds. Weaker steroids are used on the face, eyelids, diaper area, perianal skin, and intertrigo of the groin or body folds. Moderate steroids are used for atopic dermatitis, nummular eczema, xerotic eczema, lichen sclerosis et atrophicus of the vulva, scabies (after scabiecide) and severe dermatitis. Strong steroids are used for psoriasis, lichen planus, discoid lupus, chapped feet, lichen simplex chronicus, severe poison ivy exposure, alopecia areata, nummular eczema, and severe atopic dermatitis in adults.〔 To prevent tachyphylaxis, a topical steroid is often prescribed to be used on a week on, week off routine. Some recommend using the topical steroid for 3 consecutive days on, followed by 4 consecutive days off.〔Recommendations from New Zealand Dermatological Society Incorporated on (corticosteroids )〕 Long-term use of topical steroids can lead to secondary infection with fungus or bacteria (see tinea incognito), skin atrophy, telangiectasia (prominent blood vessels), skin bruising and fragility. The use of the finger tip unit may be helpful in guiding how much topical steroid is required to cover different areas of the body. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「topical steroid」の詳細全文を読む スポンサード リンク
