In this study of 246 black men, patients were randomly assigned to receive Viagra or placebo for six weeks, at which point they were given the choice to switch to the alternate treatment for another six weeks. At week six, a significantly larger percentage of Viagra-treated patients reported improved erections and improved ability to have sexual intercourse (79 percent and 81 percent) compared with placebo-treated patients (38 percent and 36 percent). Additionally, patient satisfaction was greater in the Viagra-treated group than in the placebo group.
Data also presented at the meeting by Culley Carson, M.D. of the University of North Carolina, Chapel Hill, examined the prevalence of ED in a nationally representative population sample of white, black and Hispanic American men, as defined by US census criteria, aged 40 and above. The study found that ED was a common problem among black men, with 24 percent of men reported to be only "sometimes" or "never" able to get and keep a satisfactory erection, compared to 22 percent of white and 20 percent of Hispanic men respectively.
Cardiovascular disease, high blood pressure and diabetes are all highly prevalent among black men. Because ED is often associated with such conditions, it is especially important to screen and treat black men who are experiencing erection problems," said Jean Bonhomme, M.D., Founder, National Black Men's Health Network. "We have now confirmed that Viagra is an effective and well tolerated treatment option for these men."
