All these agencies impede the enzyme phosphodiesterase kind 5 (PDE-5) and pertains to a class of pharmaceuticals called phosphodiesterase (PDE) inhibitors.
Viagra was the first and is likely the most well renowned of the three PDE-5 inhibitors utilised to heal erectile dysfunction. Viagra was accepted as an productive agency for healing erectile dysfunction in March 27, 1998. Viagra is constructed by Pfizer, Inc.
Levitra was the second PDE-5 inhibitor to arrive to market in the United States, and it was accepted by the FDA in August 19, 2003. Levitra is constructed by Bayer Pharmaceuticals Corporation.
Cialis was the third PDE-5 inhibitor to arrive to market and was accepted by the FDA at the end of November 21, 2003. Cialis is constructed by Lilly ICOS LLC.
The foremost benefit of PDE-5 inhibitors is that they manage not origin an erection at unsuitable times, because they proceed only in answer to sexy stimulation. If there is no sexy stimulation pharmaceutical continues in the background. All three are taken orally former to designed sexy undertaking, portraying to boost body-fluid flow in the penis in answer to sexy stimulation. However, there are significant dissimilarities between the three, dissimilarities that could leverage security, specificity, length of activity, harmful consequences, and finally, public acceptance inside this class of drug.
Mechanism of Action
PDE-5 inhibitors manage not exactly origin an erection of the penis, but they adjust the body’s answer to sexy stimulation by enhancing the result of the nitric oxide, a chemical that is commonly issued throughout stimulation.

Pharmaceutical Forms, Onset of Action and Duration of Effect
Viagra and Levitra disagree only minimally in periods of their structure, while Cialis disagrees markedly from Viagra and Levitra in periods of its molecular structure, which is furthermore echoed in pharmacokinetic differences.
Viagra: 25 mg, 50 mg 100 mg tablets
Onset of action: 30 minutes (effect delayed if taken with food)

Levitra is contraindicated in patients taking alpha-blockers.
Cialis is contraindicated in patients taking alpha-blockers, except for tamsulosin (Flomax).
