Prescription ED medicines are created to improve, increase, and stimulate blood flow to the penis. Each drug works in different ways with specific properties of your body. Each ingredient works in different ways and target a different part of the process.
One of the key ways this is done is focusing on something called PDE5. Such drugs inhibit PDE5 and enhance the effects of nitric oxide improving blood flow and relaxing muscles in the penis. This increases blood flow and relaxed muscles allows you to get an erection in response to sexual stimulation.
There are three common and popular medications on the market:
All three medications work in much the same way. Sildenafil was developed as a heart medication (history). They inhibit PDE5 resulting in the increase of nitric oxide. These medications vary in dosage, how long they work and their side effects. Of the three drugs, Cialis (Tadalafil) has the longest half-life which means it lasts longest in your body but also takes longer to start to work.
Avanafil approved by the FDA in 2012 is the newest ED drug to win approval works quickly, studies show that most men will be able to have an erection in as little as 15 minutes. Avanafil is marked as Stendra by Vivus. Sildenafil (Viagra) and Vardenafil (Levitra) works in 30 – 60 minutes, while Tadalafil (Cialis) take even longer.
The also have serious and potentially deadly side effects. This is why many men have turned to natural over the counter herbal cures. Natural alternatives are also much much cheaper and do not require an expensive trip to the doctors and tests.
Men who have erectile dysfunction may be eager to solve that specific problem, but a new study adds to a growing body of evidence suggesting that erectile dysfunction may be a sign of other health problems.
Researchers found 2,200 deaths linked to prescription erectile dysfunction (ED) drugs, based on reports to the Food and Drug Administration’s (FDA) Office of Surveillance and Epidemiology from 2000 to 2010. Avanafil is thought to have lower side effects than other drugs in its class.
