Subjects were randomized to use of a placebo (n = 82), 5 mg of tadalafil (n = 85), or 50 mg of sildenafil (n = 77) daily for 6 months. Electroretinographs were recorded using the International Society for Clinical Electrophysiology of Vision (ISCEV) protocol and standardized ERG equipment at all 15 study sites. Other tests of ocular anatomy and visual function were performed at each assessment. The primary outcome was the average mean change for both eyes from baseline to endpoint in ERG b-wave amplitude using dark-adapted combined standard response to a bright ISCEV standard flash. Secondary endpoints were other ERG parameter changes, visual acuity, number of errors in color discrimination testing, mean deviation in automated visual field testing, and intraocular pressure (IOP). No significant differences were found between treatment/placebo groups for the primary outcome, most other ERG variables, visual function, IOP, or anatomic assessments.

Results of this study in men aged ≥45 years with ED and concomitant lower urinary tract symptoms showed that if taken daily, sildenafil. From the American Urological Association ATLANTA—For the first time, an oral phosphodiesterase type 5 (PDE-5) inhibitor has been shown to improve lower urinary tract symptoms associated with benign prostatic hyperplasia (BPH) in men with concomitant erectile dysfunction (ED), according to data presented at the annual meeting of the American Urological Association. Results of this study in men (aged ≥45 years) with ED and concomitant lower urinary tract symptoms showed that if taken daily, sildenafil (Viagra) was comparable to alpha-1 blockers in improving the International Prostate Symptom Score (IPSS) in these patients. “This is the first study of its kind,” said lead investigator Kevin Mc Vary, MD, of Northwestern University Feinberg School of Medicine, Chicago. “It is important, because it links the 2 diseases biologically. If you can affect a man’s erectile dysfunction simultaneously while trying to impact his lower urinary tract symptoms with 1 pill, it is very intriguing and exciting.” Previous studies have suggested that PDE-5 inhibition promotes relaxation of smooth muscles in the lower urinary tract and may improve urinary tract symptoms. In this 12-week, double-blind, placebo-controlled study, 366 men who scored ≤25 on the erectile function domain of the International Index of Erectile Function, had an IPSS of ≥12, and a prostate-specific antigen score . “Both diseases occur with aging in men, and it was thought to be just overlapping curves. But to show that you can impact them with a medication shows there is a common pathophysiology,” he added. The safety and scientific validity of this study is the responsibility of the study sponsor and investigators.
