| One of the most efficacious treatment methods of impotence in men is Viagra oral therapy. The blue pill was initially introduced to cure heart diseases and prevent heart attacks. Later on scientists discovered that the pills could dilate blood vessels.
Erectile dysfunction (impotence) is a condition when the penis does not become firmer and larger when a male is sexually excited, or when he cannot sustain an erection. Viagra may help a man with ED attain and sustain an erection during sexual arousal. Viagra is for males only and must be used if recommended by a medical practitioner.
An erection is the result of an increase in blood inflow into the genitals and in particular to the penis. The medication works by relaxing the blood vessels of the penis during sexual stimulation, so more blood can flow into it.
When taken orally before a meal, maximum drug concentration in plasma is observed within 30 to 120 minutes after administration.
Viagra can efficient up to 4 hours, but the response decreases with time. When taken with products rich in fat, the effectiveness of the drug lowers.
As well as other prescription medications, Viagra can trigger adverse side effects in some males. The most frequently observed side effects in males taken Viagra are headaches, stomachache, diarrhoea, sweating, redness in face, neck and/or chest, temporary visual changes (colour perception changes, light perception changes and blurred vision).
The medication is contraindicated in men with cardiac problems, physical deformities of the penis, in males predisposed to lengthy erections brought on by blood cell disorders, liver and kidney problems, in males taking certain medications for HIV, in those over 65, in males having a recent history of a cardiac attack, stroke or heart rhythm disorder. Deaths have occurred during sex in males using the pill.
If taken with other drugs (nitrate or nitroglycerin cardiac medicines), Viagra can trigger serious drop in blood pressure, which can be lethal. Thus, before taking the drug, talk to your medical practitioner about potential drug-to-drug interactions. |
