| One of the most efficient treatments of sexual dysfunction in men is Viagra oral therapy. The blue pill was initially invented to cure heart diseases and preclude heart attacks. Later on scientists concluded that the pills could relax blood arteries.
Erectile dysfunction (impotence) is a condition when the penis does not harden and engorge when a male is sexually excited, or when he cannot maintain an erection. Viagra may help a man with ED achieve and sustain an erection when he is sexually aroused. Viagra is developed for men only and must be taken as prescribed by a doctor.
An erection is the result of an increase in blood inflow into the genitals and particularly to the penis. The drug relaxes the blood vessels of the penile area during sexual stimulation, so blood flow to the organ increases.
When taken orally on an empty stomach, maximal drug concentration in blood is reported within 30 to 120 minutes after administration.
Viagra can effective up to 4 hours, but the response lessens with time. When taken with high fat products, the efficiency of the medication lowers.
As well as other prescription drugs, Viagra can lead to adverse side effects in some people. The commonest side effects are bad headaches, general ill feeling, upset stomach, redness in face, neck and/or chest and visual problems.
The medication is contraindicated in men with heart problems, forcible deformities of the penis, in men with a predisposition to lengthy erections triggered by sickle cell anemia, multiple myeloma (a type of cancer), leukaemia, liver and kidney problems, in males taking certain medications for HIV, in those over 65, in men having a recent history of a heart attack, stroke or heart rhythm disorder. There have been examples when males taking the drug died during sex.
When taken with other drugs (nitrate or nitroglycerin cardiac medicine), Viagra can bring on dangerous drop in blood pressure, which can be fatal. Thus, before taking the medication, consult your general practitioner about potential drug-to-drug interactions. |
