What is Topical Corticosteroid Tachyphylaxis

Topical corticoids and oatmeal are widely used to treat dermatologic diseases. Adverse drug reactions of topical corticoids (ADRs) are frequent, especially in long treatments or with potent corticoids. This chapter proposes a new pharmaceutical form of a topical corticoid(s) and colloidal oatmeal with a device for a rigorous dosing and discontinuation of treatment (titration and dose reduction). This new pharmaceutical form was based on a conceptual framework. The proposed device avoids the use of the FTU method, “fingertip unit,” which may not be accurate. A precise dosing can potentially reduce the risk of ADRs. Colloidal oats confer anti-irritant, moisturizing, and anti-inflammatory properties, which may reduce the needed time to control and treat the skin disease. A new pharmaceutical form of a topical corticoid and colloidal oatmeal with a precise dosing device is proposed as a safer and efficient alternative to the FTU method.
