![]() There is no specified time limit for low-potency topical corticosteroid use. Topical corticosteroids are applied once or twice per day for up to three weeks for super-high-potency corticosteroids or up to 12 weeks for high- or medium-potency corticosteroids. Background: Topical corticosteroids are widely used to treat dermatological problems. ![]() One fingertip unit is the amount of medication dispensed from the tip of the index finger to the crease of the distal interphalangeal joint and covers approximately 2% body surface area on an adult. Patients may be taught application using the fingertip unit method. Correct patient application is critical to successful use. The quantity of corticosteroid prescribed depends on the duration of treatment, the frequency of application, the skin location, and the total surface area treated. Topical corticosteroids have a major role in the management of many inflammatory and autoimmune skin diseases (eg, atopic dermatitis, allergic contact dermatitis, radiation dermatitis, psoriasis, vitiligo, lichen planus, discoid lupus erythematosus). They are available in formulations such as ointments, creams, lotions, gels, foams, oils, solutions, and shampoos. Topical corticosteroids can work safely and effectively in patients who are pregnant or lactating. Cream, ointment: Temovate: 0.05: Gel, solution (scalp) Generic only 0.05: Cream: Tasoprol: 0. When prescribing topical corticosteroids for use in children, lower potencies and shorter durations should be used. Comparison of representative topical corticosteroid preparations (classified according to the United States system) Potency group Corticosteroid: Vehicle type/form: Brand names (United States). The risk of adverse effects increases with prolonged use, a large area of application, higher potency, occlusion, and application to areas of thinner skin such as the face and genitals. Topical corticosteroids are classified by strength and the risk of adverse effects such as atrophy, striae, rosacea, telangiectasias, purpura, and other cutaneous and systemic reactions. Such studies will not only help to explain how corticosteroids work, but also create a background that is essential for the development of novel non-steroidal anti-inflammatory drugs.Topical corticosteroids are an essential tool for treating inflammatory skin conditions such as psoriasis and atopic dermatitis. Additional studies of the mechanism of action of corticosteroids are warranted. Although this theory based on protein synthesis may not explain all effects of corticosteroids, these examples illustrate that a specific action on the molecular level can explain some of the characteristic and typical pharmacological effects of topically applied corticosteroids. These actions of corticosteroids on arachidonic acid metabolism and interleukin-1 formation produce anti-inflammatory, immunosuppressive and anti-mitogenic effects. In contrast, corticosteroids inhibit mRNA responsible for interleukin-1 formation. The formed lipocortin inhibits the activity of phospholipase A2, which releases arachidonic acid, the precursor of prostanoids and leukotrienes, from phospholipids. Thus corticosteroids are known to stimulate the production of a glycoprotein called lipocortin. Because mRNA acts as template for protein synthesis, corticosteroids can either stimulate or inhibit the synthesis of specific proteins. ![]() The binding process then changes the transcription of messenger RNA (mRNA). Topical corticosteroid creams and ointments are applied to the skin to reduce inflammation in conditions such as eczema, dermatitis and allergic skin reactions. You might see an improvement in your skin after 2 to 3 weeks of treatment. ![]() Apply Metaz-S Ointment 1-2 times a day or as prescribed by your doctor. They are generally used to relieve symptoms and suppress signs of the disorder when other measures such as emollients. It also reduces swelling and redness at the affected area. Topical corticosteroids are used for the treatment of inflammatory conditions of the skin (other than those arising from an infection), in particular eczema, contact dermatitis, insect stings, and eczema of scabies. 72 Since then, another 30 or so compounds have been developed, each in different formulations (e.g. Metaz-S Ointment moisturizes the skin and helps reduce dryness and itchiness. Hydrocortisone was first used as a skin treatment in 1952, when it was found to improve various dermatoses when applied topically. This complex moves into the nucleus, where it binds to DNA. Topical corticosteroids have been one of the cornerstones of the treatment of atopic eczema for > 50 years. After passage through the cell membrane corticosteroids react with receptor proteins in the cytoplasm to form a steroid-receptor complex. Corticosteroids modify the functions of epidermal and dermal cells and of leukocytes participating in proliferative and inflammatory skin diseases. ![]()
