Generic Viagra makes it simple for ED men to regain virile functions. However, the drug form does not cause a man to be sexually aroused. The reputed drug is the only trusted formula that works effective if you are sexually aroused. When you are sexually aroused, nervous system in erectile tissue of penile releases nitric oxide (NO). This nitric oxide stimulates an enzyme, which produces a messenger called cyclic guanosine monophosphate (cGMP). Further, cGMP relaxes the smooth muscle cells. Firstly, this act leads arteries in your penile dilate and eases flow of blood. Another result is that erectile tissue in the penile itself fills with blood. This combined process results in sturdy erection that stays for longer time. Generic Viagra does its working by maintaining the level of cGMP in the smooth muscle cells. In case you are not turned on, your brain may not stimulate the release of any nitric oxide and you will not produce any cGMP, which eventually will lead to failure in erection even post consumption of pill.
Clinical studies have shown that Generic Viagra is more effective that other drugs in the same class for improvement in erectile function. Although the drug is established to be a safe and effective, it isn't appropriate for everyone and may not work in all cases. Sildenafil citrate in the drug helps to attain erection but it relies on natural arousal as a trigger.
On average, the drug becomes effective in just an hour when you consume it on an empty stomach. The drug can remain effective for between four and six hours. If you consume the drug form post high fat meal, drug may take longer than an hour to show its effective results.
