Tamsulosin is a highly selective α1-adrenoreceptor antagonist. It has been developed to treat signs and symptoms of benign prostatic hyperplasia. Tamsulosin is absorbed quickly and completely in intestinal mucosa and is eliminated gradually after oral administration, which might generate some side effects as postural hypotension in number of patients. Transdermal drug delivery systems were developed for prolonged tamsulosin delivery in order to control its bioavailability and minimize its side effects. Hence, the present review aims to discuss thoroughly the various transdermal drug delivery systems of tamsulosin investigated in recent years. This review also discusses the skin as a route of drug administration, technologies in transdermal drug delivery along with different techniques used in the preparation of transdermal delivery systems of tamsulosin and their effects on its release and permeation.
