VIVUS, the company that is testing the new ED compound avanafil, annouced that they have had some good results in a recent phase III study. Up to 80% of men with ED had a good response, some within 15 minutes after taking avanafil.

 

The drug is similar to Viagra (sildenafil) but acts faster. Hopefully it will be priced lower.
