Ingredients

Viagra’s active ingredient is Sildenafil Citrate.

Action

The scientists who discovered sildenafil citrate were not looking for a treatment for erectile dysfunction at all, but rather a drug to treat hypertension and angina. While the treatment had little effect on these ailments, it did produce pronounced erections. Viagra increases the efficiency of hormones produced by sexual desire, which will cause better blood supply in penis, relaxing smooth muscle. In spite of rumors, there is no clinical evidence that it improves sexual performance in men who are not experiencing regular erectile dysfunction.

So if there is no sexual desire, Viagra is useless.
