The Wall Street Journal reported that the FDA has approved another erectile dysfunction drug.
Stendra (avanafil), made by Vivus, works by increasing blood flow, as do competitors Viagra by Pfizer Inc., Cialis by Eli Lilly & Co., and Levitra by Bayer AG and GlaxoSmithKline. The Journal notes that Stendra is the first product approved for Vivus, which also has an obesity drug, Qnexa, awaiting FDA approval.
The AP reported, “Vivus licensed Stendra from Japanese drugmaker Mitsubishi Tanabe Pharma. It has worldwide rights to the drug except for some countries in the Asia-Pacific region.”
But “analysts … expect Vivus to sell Stendra to another drug company to help fund future sales of its experimental obesity drug Qnexa.”
The Philadelphia Daily News reported that while “Viagra can take up to 60 minutes to work,” avanafil “requires patients to take it 30 minutes before sexual activity.”
And “the FDA said Stendra, like other ED drugs, should not be used by men who also take nitrates, commonly used to treat chest pain, because the combination can cause a sudden drop in blood pressure.”
Also side effects may include “headache, redness of the face and other areas, nasal congestion, common cold-like symptoms and back pain.”
Finally, “the FDA warned patients who experience a sudden loss of vision or hearing to stop taking the drug and call a doctor right away.”
USA Today in its “Healthy Perspective” blog, called it “a faster-working alternative to Viagra and other erectile dysfunction drugs.”
Indeed, “the drug has been shown to work in as little as 15 minutes.”
