    Erectile dysfunction: an overview

    Peter Pommerville
    Canadian Journal of Urology, Vol.10, Suppl.1, pp. 2-6, 2003
    Abstract Sexual function is a central part of a man’s identity, helping to define who he is, and how he feels about himself. It is also a key determinant of relationship health. Erectile dysfunction (ED) threatens all of this, and is thus an important topic in male health. Erectile dysfunction is common around the world, especially in older men. Risk factors for ED overlap significantly with those for cardiovascular disease and endothelial dysfunction, especially diabetes. More >

    A historical review of erectile dysfunction

    Luc Valiquette
    Canadian Journal of Urology, Vol.10, Suppl.1, pp. 7-11, 2003
    Abstract Over the last three decades, there has been a significant increase in our understanding of the physiologic mechanisms responsible for erectile dysfunction. Erectile dysfunction has become a topic of considerable media and societal interest and acceptance. Paralleling the increase in knowledge has been an explosion in therapeutic options. This article will evaluate the therapeutic options, from a historical perspective of what has been available, and outline the progress that has been made. More >

    Pharmacology of phosphodiesterase 5 inhibitors

    Serge Carrier
    Canadian Journal of Urology, Vol.10, Suppl.1, pp. 12-16, 2003
    Abstract The phosphodiesterase enzymes, of at least 11 types, are ubiquitous throughout the body, and perform a variety of functions. Phosphodiesterase type 5 (PDE5) is the predominant enzyme in the corpus cavernosum, and plays a crucial role in penile erection. Inhibitors of PDE5 are the most effective oral agents in the treatment of erectile dysfunction. Sildenafil, tadalafil, and vardenafil are all potent inhibitors of PDE5 and show the same mechanism of action, although they have some pharmacological differences that may translate into varying clinical effects.

    Tadalafil: a new agent for erectile dysfunction

    Gerald B. Brock
    Canadian Journal of Urology, Vol.10, Suppl.1, pp. 17-22, 2003
    Abstract Oral phosphodiesterase 5 (PDE5) inhibitors for the treatment of erectile dysfunction are preferred by most men, and are recommended in guidelines as first-line therapy, because of convenience, high efficacy, and low rates of side effects. Tadalafil (Cialis™) is a new agent that has been studied in different patient populations. It has a different molecular structure than other PDE5 inhibitors, and a different pharmacologic profile that provides a longer period of effectiveness than other agents. This article will review clinical trials on tadalafil, to provide a comprehensive overview of its efficacy and safety. More >

    Cardiovascular safety of PDE5 inhibitors

    Sender Herschorn
    Canadian Journal of Urology, Vol.10, Suppl.1, pp. 23-28, 2003
    Abstract Erectile dysfunction (ED) and cardiovascular disease share many of the same risk factors and have some common elements of pathophysiology. Clinically, they often coexist. Another link between the two conditions is that sildenafil, the first oral therapeutic agent effective in treating ED, has been shown to potentiate the hypotensive effects of nitrates, a potentially serious side effect. Nitrates are commonly used in the treatment of coronary artery disease. As such, sildenafil (and, likely, other new phosphodiesterase type 5 [PDE5] inhibitors) is contraindicated in men who use nitrate medications. This article will examine the risk of More >
