Viagra

Viagra is one of the most widely usable and effective medicines for the treatment of ED (Erectile Dysfunction). In many cases, a single tablet helps improve circulation and maintain a simple, easy continuous erection. Like all medicines, Sildenafil has a specification and half-life which determines how long it lasts for the treatment of ED. In this guide, we show how long Sildenafil is active and compares it to many others.  Also, you can discuss with a doctor to know how to prevent erectile dysfunction.

Research indicates that erectile dysfunction affects more than 12 million men in the USA. Though the frequency of this problem increases with age and also it is not moderate to older adults. According to the result, Viagra usually starts working faster on taking an empty stomach because the possibility of slowing the absorption of an active digestive system in the body is less.

Sildenafil works by blocking Phosphodiesterase-5 (PDE-5) enzyme. An enzyme that promotes the breakdown of cGMP (Cyclic Guanosine Monophosphate) and regulates blood flow in the penis. However, sexual excitement is required to work and as a result, the blood vessels spread in the lungs.
