VIAGRA (sildenafil) as candidate drug for Alzheimer’s disease

 

According to findings published in Nature Aging, the research team, led by Feixiong Cheng, Ph.D., of Cleveland Clinic's Genomic Medicine Institute, used computational methodology to screen and validate FDA-approved drugs as potential therapies for Alzheimer's disease. Through a large-scale analysis of a database of more than 7 million patients, they determined that sildenafil is associated with 69% reduced incidence of Alzheimer's disease, indicating the need for follow-up clinical trial testing of the drug's efficacy in patients with the disease.

"Recent studies show that the interplay between amyloid and tau is a greater contributor to Alzheimer's than either by itself," said Dr. Cheng. "Therefore, we hypothesized that drugs targeting the molecular network intersection of amyloid and tau endophenotypes should have the greatest potential for success."

Without the development of effective new treatments, Alzheimer's disease is set to impact 13.8 million Americans by 2050, underscoring the need for rapid development of prevention and treatment strategies. Drug repurposing -- use of an existing drug for new therapeutic purposes -- offers a practical alternative to the costly and time-consuming traditional drug discovery process.
