Viagra Information:

One of themain disorders in men, which leads to social insecurity andpsychological distress, is an erectile dysfunction (ED) or impotence.Erectile dysfunction is caused by the lack of flow of blood into theblood vessels in the penis. Erectile dysfunction can be of varioustypes, and can be caused by a number of things such as psychologicalstress, current medication, or a medical disorder. Impotence caused bypsychological stress is only temporary and may disappear on its own,however if impotence is caused by a medical disorder then it needstreatment.

Satisfaction of sexual desires is one of the main desires of humans.And medical disorders such as erectile dysfunction can cause a greathindrance in fulfilling this desire, let alone the humiliation onesuffers in front of his sexual partner. Main targets of this disorderhave been elderly men. Studies have shown that as little as 1% of menbelow the age of 30 suffer from erectile dysfunction; however thepercentage rises sharply with age, going as high as 75% for men over 70years of age.

Viagra is taken orally - thus the painful procedure of injecting aneedle into the penis is avoided. Moreover by avoiding an injection,one avoids side effects such as bleeding from the injection site,infection, and general discomfort. However as it is not injecteddirectly into the penis (but consumed orally) it takes relativelylonger to show results. Viagra helps to get a full erection andmaintain it for the satisfactory fulfillment of sexual desires.

Sildenafil Citrate, the main ingredient in Viagra, was developed nearlya decade ago by Pfizer. Since its introduction to the world widemarket, Viagra has become the most widely used medicine for thetreatment of erectile dysfunction. Apart from it’s use for thetreatment of erectile dysfunction, studies have shown the effectivenessof Viagra for the treatment of various other diseases such as PulmonaryArterial Hypertension (PAH, high blood pressure in the pulmonary veinsand pulmonary arteries). It can also be used for the treatment of highaltitude sickness (high altitude pulmonary edema).

The usual dosage for Viagra tablets is around 25mg to 100mg once in 24hours and is generally taken at least one hour before sexualintercourse. The actual dose per day depends on the doctor’sprescription, as it depends on the patient’s condition. Generally it isadvised to start with a dose of 25mg.

Another reason for the popularity of Viagra is that it has only mildside effects, which in most cases don’t require any medical treatmentat all. Side effects observed in clinical trials include nausea,headache, blurred vision and photophobia (increased sensitiveness tolight). Most of these symptoms disappear on their own. In very rarecases, reports of highly adverse effects of Viagra include heartattack, severe hypnotism, stroke and sudden hearing loss.
