Topical steroids, having revolutionized dermatotherapy over several decades, remain the mainstay of treatment for steroid-responsive inflammatory dermatoses worldwide. Challenges, nevertheless, abound on the usage of topical steroids, particularly with their inappropriate application. Several steps and improved formulations are constantly evolving in the scientific world, aimed at addressing most of the associated adverse events. However, until the dawn of the 'ideal topical steroid', the implications of application misuse will remain significant. This review discusses the concept of 'misuse and abuse' of topical steroids, gives an overview of topical steroids, differentiates 'misuse' as opposed to 'abuse' of application of topical steroids as they occur in different settings and provides a schematic algorithm for the appropriate and optimal application of topical steroids. Consequently, this separation will allow a more accurate estimation of the burdens of these two aspects that require different solutions. 31-40 (2007) Topical glucocorticoids are the foundation of dermatotherapeutics [1], particularly for the noninfected inflammatory dermatoses, such as the eczemas and dermatitis. Their availability since 1952 has marked the most important milestone in dermatology to date [2,3]. Although the 'ideal' topical steroids have not yet been synthesized, topical administration of steroids still remains the safest mode of administration for glucocorticoids.Topical steroids are derivatives of the prototype hydrocortisone, a natural glucocortico steriod of the adrenal cortex. Chemical substitutions at certain key positions of the cyclopentanophenathrene nucleus, altering both its glucocorticoid and mineralocorticoid properties, affects the potency of these drugs. For example, halogenation at the 9-α position enhances the potency by improving activity within the target cell and decreasing breakdown into inactive metabolites [4], while masking or removing the hydrophilic 17-dihydroxyacetone side chain or the 16 α-hydroxy group increases the lipophilicity of the molecule, thereby enhancing penetration through the stratum corneum [1,5].The existence of a reservoir within the stratum corneum for most topical xenobiotics, particularly topical steroids [6,7], affects the choice of application frequency and the dose, while percutaneous absorption is dependent on the intrinsic property of the steroid, the vehicle used, the anatomical site, age of patient and method of application (i.e., under occlusion or hydration). However, individual variation in percutaneous absorption can also be quite pronounced. All of these factors must be taken into account when considering the potential for undesirable effects of topical steroids.Abuse of steroids could be regarded as the use of steroids to achieve purposes other than a therapeutic one, while misuse of steroids can be regarded as the inappropriate use of steroids for therapeutic purposes. These terms are introduced in this article for the purpose of describing the inapt use of prescr...
