A new study published in the Journal of the American Medical Association (JAMA) shows the same drug can be sold over the counter without needing a prescription, and it also shows it could be used as a way to promote weight loss. The study, presented at the American Heart Association Scientific Sessions in Washington, D. C., in September 2015, looked at two popular brands of Viagra, known generically as sildenafil and tadalafil, and two alternative options for treating erectile dysfunction, including sildenafil and tadalafil. The research team found that patients with mild to severe erectile dysfunction (ED) who took sildenafil or tadalafil had a modest increase in blood pressure compared with patients taking placebo. The researchers also found that patients who took sildenafil were not significantly more likely to have a heart attack or stroke, a rare but fatal heart condition. The researchers also found that patients who took the two brand-name sildenafil drugs did not experience any clinically significant side effects, including headache, dizziness, stomach ache, or upset stomach. Overall, the findings were similar for patients who took either brand-name or generic sildenafil or tadalafil, which is a class of drugs that are commonly used to treat ED. Sildenafil was the drug of choice for some, but the study authors say that this finding could not be confirmationally tested using clinical trials.
VIDEOThe JAMA study was a follow-up of a phase III randomized, double-blind, placebo-controlled trial of sildenafil, a generic equivalent of Pfizer’s Viagra, in more than 1,100 patients with mild to severe ED who took either sildenafil or tadalafil. The study was funded by Pfizer, which has a joint venture with Takeda to develop and commercialize sildenafil. The two drugs were designed to treat different types of ED. The researchers compared the patients to a control group, which was randomly assigned to take either placebo or sildenafil. The control group received standard care, while the sildenafil group received standard care and sildenafil. The study found that patients who took sildenafil had a modest increase in blood pressure compared with patients taking placebo. The researchers also found that patients who took the two brand-name sildenafil drugs did not experience any clinically significant side effects, such as headache, dizziness, stomach ache, or upset stomach. The researchers also found that patients who took the two brand-name drugs were not significantly more likely to have a heart attack or stroke, a rare but fatal heart condition.
“These findings are exciting news for both physicians and patients with mild to severe ED,” said Dr. Katerina A. Parikh, an associate professor of medicine at Harvard Medical School who is also the study’s lead author. “These findings suggest that patients who take sildenafil or tadalafil should be treated with caution and should be prescribed caution because the risk of cardiac events, such as a heart attack or stroke, is higher for patients taking sildenafil.”
Researchers also found that patients who took the two brand-name drugs were not significantly more likely to have a heart attack or stroke, a rare but fatal condition. They also found that patients who took sildenafil were not significantly more likely to have a heart attack or stroke, a rare but fatal condition. Overall, the researchers said, the findings were similar to those for patients who took either sildenafil or tadalafil.
“While these findings are exciting, they also emphasize that the potential benefits of using sildenafil or tadalafil for treating ED are modest,” said Dr. A. V. Shah, a senior fellow in the department of health and clinical pharmacology at Harvard Medical School and a coauthor of the study. “Patients taking sildenafil or tadalafil should be prescribed caution and should be advised to see their doctor if they experience any adverse reactions to these drugs or to seek alternative treatment options.”
The drug is also a phosphodiesterase type 5 (PDE5) inhibitor, a class of drugs that is used to treat erectile dysfunction and pulmonary arterial hypertension.
