Excipients in topical corticosteroid preparations in Canada.
Topical corticosteroids are widely used for the treatment of dermatoses in Canada. The effects of the various nontherapeutic components of these formulations are less well known than those of the active ingredients and may cause adverse reactions. Information on the components is fragmentary and is scattered throughout the literature. We have attempted to consolidate this information into one source. Recent provincial legislation requiring the generic substitution of interchangeable products and the nondisclosure of all ingredients in product labelling hinder the search for an excipient that has caused an adverse reaction. Practitioner participation in the Cutaneous Adverse Reaction Registry of the Canadian Dermatology Association will identify sensitizing excipients and will support efforts by the profession to obtain more effective and safer products.
