The potential use and abuse of viagra and other PDE-5 inhibitors for the treatment of erectile dysfunction

Studies worldwide suggest that the majority of men maintain moderate to high levels of sexual interest throughout their lifespan, but often report some degree of sexual dysfunction. This review is designed to provide essential information regarding erectile dysfunction (ED) and its treatment with Viagra (sildenafil) and other phosphodiesterase-5 (PDE-5) inhibitors such as Levitra and Cialis. The prevalence and aetiology of ED, in comparison to the normal changes associated with ageing, are presented. Misconceptions about Viagra and other PDE-5 inhibitors, as well as these drugs' mechanism of action, clinical efficacy, side-effects, and contraindications are discussed, and the impact of these male enhancement drugs upon sexual partners, their possible use among women, and the influence of extensive product marketing campaigns are addressed. The potential for psychotherapists to assist men (and their partners) with treatment via health education, e-health information, and concurrent sex therapy also is highlighted. The overarching goal is to assist individuals in making informed decisions about the appropriate use of performance enhancing drugs.
