Product Description

The FDA approved Viagra vigra 1998, and it became the first oral therapy for erectile dysfunction on the market. Vardenafil hydrochloride (Levitra) was approved in September, 2003, and Tadalafil (Cialis) was approved in November, 2003. Viagra, Levitra and Cialis work in much the same way. These PDE-5 inhibitors share many similarities, but they have differences as well. Although sildenafil citrate (Viagra), vardenafil HCl (Levitra) and tadalafil (Cialis) sometimes are called sexual viagra or cialis for premature ejaculation, pastille gen viagra do not directly cause an erection of the penis, but alter the body's response to sexual stimulation by enhancing the effect of the nitric oxide, a chemical that is normally released during stimulation. Nitric oxide causes relaxation of the muscles in the penis, which allows for better blood flow to the penile area.
