Just when Sildenafil citrate, popularly marketed as Viagra, hit the market, males with problems in their sexual activities, especially when it comes to erection, have finally found a solution to solve the matter easily. Once this medicine is taken, it can already take effect after 60 minutes and last for around 4 hours. Psychological issues related erectile dysfunction can also be overcome with the help of the pill.

But other than that, Viagra has also been seen as a treatment for pulmonary arterial hypertension. This medicine allows the arterial wall to relax which results to lesser arterial resistance and pressure. Still, pulmonary hypertension is a rare condition though.

Though Viagra is considered as an effective medication and has been approved by FDA, it is still recommended that taking this pill requires a prescription from a doctor. After all, there are still some matters which need the attention of a medical expert before a prescription can be made. This is because there are some conditions that are needed to be looked after first before the medicine can be taken in by a person.
