Product Description

Viagra, also called Sildenafil, helps relax body muscles and thus increase blood flow to particular body parts. Viagra is used to treat erectile dysfunction or impotence in men.

Common Uses

The commonest use of Viagra is the treatment of erectile dysfunction. Erectile dysfunction can be described as the inability to sustain an erection that can satisfactorily complete an act of sexual intercourse. This drug is the standard treatment for erectile dysfunction and is recommended by leading medical authorities. In fact, it is also recommended for use by men whose full sexual function has been interfered with by diabetes. People using antidepressants may also suffer from sexual dysfunction due to the illness or even the kind of treatment administered. According to research done in 1999, the use of Sildenafil also improved sexual function in men on antidepressants.

Further, Viagra is used to treats pulmonary hypertension. Sildenafil Citrate is widely used as a treatment for a rare disease called pulmonary arterial hypertension (PAH). The drug relaxes the arterial wall, leading to decreased arterial resistance and pressure. As a result, the workload of the right ventricle reduces. This improves the symptoms of the right-side heart failure.

Viagra is also used to treat altitude sickness. Sildenafil has been found to have the capacity to treat and prevent high altitude pulmonary oedema that comes with altitude sickness often experienced by mountain climbers. Although the condition has not elicited wide medical research, Sildenafil is already being used to palliate the symptoms of this condition.
