In the dose–response study, increasing doses of sildenafil were associated with improved erectile function (P values for increases in scores for questions about achieving and maintaining erections were <0.001). For the men receiving 100 mg of sildenafil, the mean score for the question about achieving erections was 100 percent higher after treatment than at base line (4.0 vs. 2.0 of a possible score of 5). In the last four weeks of treatment in the dose-escalation study, 69 percent of all attempts at sexual intercourse were successful for the men receiving sildenafil, as compared with 22 percent for those receiving placebo (P<0.001).

No effective oral therapy for erectile dysfunction is currently available.6 Normal penile erection depends on the relaxation of smooth muscles in the corpora cavernosa. In response to sexual stimuli, cavernous nerves and endothelial cells release nitric oxide, which stimulates the formation of cyclic guanosine monophosphate (GMP) by guanylate cyclase.7–9 The mechanism by which cyclic GMP stimulates relaxation of the smooth muscles remains to be elucidated.
Sildenafil is a selective inhibitor of cyclic-GMP–specific phosphodiesterase type 5, the predominant isozyme metabolizing cyclic GMP in the corpus cavernosum.10 By selectively inhibiting cyclic-GMP catabolism in cavernosal smooth-muscle cells,11 sildenafil would be expected to restore the natural erectile response to sexual stimulation but not cause erections in the absence of such stimulation.

However, back pain and joint aches can occur with Cialis. Although Viagra, Levitra and Cialis have been shown to be effective in many men with erectile dysfunction, they are not effective in patients who have a prostatectomy, unless a nerve-sparing approach was used. These medications must not be used with medications containing nitrate, such as nitroglycerin, Nitrostat, Nitro-Bid, Nitro-Dur, Isordil and Ismo, or Deponit. Sildenafil is rapidly absorbed, with maximal plasma concentrations occurring within one hour after oral administration and a mean terminal half-life of three to five hours.10 In a placebo-controlled pilot study of 12 men, sildenafil significantly improved the erectile response during visual sexual stimulation.10,12 We therefore undertook two studies to evaluate in a home setting the efficacy and safety of sildenafil in men with erectile dysfunction. In two sequential studies, we studied a total of 861 men 18 years of age or older with a clinical diagnosis of erectile dysfunction (as defined previously1) of six months' duration or longer at 37 centers in the United States. Each man had to be in a stable relationship with a female partner that had begun at least six months earlier. The cause of erectile dysfunction was determined from the medical history, physical examination, and other diagnostic procedures, including a test involving the intracavernosal injection of a vasoactive drug (done in 31 percent of the men), a RigiScan test of nocturnal penile tumescence (26 percent), penile duplex ultrasonography (21 percent), and endocrine testing (21 percent). On the basis of these evaluations, the men were classified as having organic, psychogenic, or mixed erectile dysfunction.
Of the 861 men studied, 605 (70 percent) were judged to have organic erectile dysfunction, 99 (11 percent) to have psychogenic erectile dysfunction, and 157 (18 percent) to have mixed erectile dysfunction.
