What are Viagra, Cialis and Levitra for?
Almost all men, at some time in their lives, have occasional difficulty getting and keeping an erection. Treatment for erectile dysfunction, or impotence, can range from costly mechanical devices to surgery. The medical profession is now recommending oral medications as the option of choice for treatment for Erectile Dysfunction. There are three oral drugs approved by the FDA to treat erectile dysfunction: Viagra, Cialis and Levitra. All work by increasing the flow of blood
into the penis so that when a man is sexually stimulated, he can get an erection.
What are the differences between Viagra, Cialis and Levitra?
Viagra , Cialis and Levitra work by a similar mechanism to cause erections. There are
differences in how quickly it works and how long the drug works. Levitra works a little longer
than Viagra. But they both take effect in about 30 minutes. With Levitra, the effects last for
about 5 hours. With Viagra, the effects last approximately 4 hours.
Cialis works a bit faster (within about 15 minutes), and the effects last much longer -- up to 36 hours in some cases.
Viagra (sildenafil citrate) is definitely the most popular, but popularity alone shouldn’t
be a determining factor. The more recently approved Cialis (tadalafil) and Levitra (vardenafil
hydrochloride) are also highly effective and very safe alternatives, although they may not be as
popular yet. The problem for most people is actually deciding on the best alternative for them.
For starters, all three drugs help relax compromised or hardened penile arteries thus allowing more blood to flow into the penis and subsequently cause an erection.
