Pharmacological treatment of erectile dysfunction.

There is growing evidence that the field of pharmacotherapy, particularly oral drugs, will be dominant in the future management of sexual dysfunction. Basic research has led to the understanding of the intracellular mechanisms that control penile smooth muscle contractility and therefore erection, opening a vast area for pharmacological intervention. Moreover, the importance of central neurohormonal mechanisms has made these pathways the target for new centrally acting drugs. Given these trends most patients suffering from erectile dysfunction will respond to pharmacological agents in the not so distant future.
