Viagra (Sildenafil citrate)

Increasing pollution in our environment directly puts a debilitating affect on the erection capacity of penis. Continuous exposure to noise and air pollution leaves the penis unable to achieve full erection even when sexual stimulation is provided. One of the most successful drugs producing company called Pfizer pharmaceuticals has introduced its product which effectively fights impotence. This miraculous drug is available in the medical stores by the name of Pfizer’s Viagra. Viagra helps achieve potent erection highly dreamed of. Since its production Viagra has earned the satisfaction of its costumers all over the world. Viagra truly comes triumphant in the fight between impotence and Viagra.

Persons suffering from the disease of impotence are unable to erect their penis because of the decreased accumulation of blood in the spongy tissue of the penis. Blood must fill the spaces present in the spongy tissue, called carpus cavarnosa of the penis, for erection to occur. The blood enters these spaces from the vessels lining the spongy tissues. The blood leaves the vessels when these vessels dilate. The vessels dilate under the influence of cGMP, a factor causing vessel dilation. This cGMP is synthesized from GTP under the action of an enzyme called guanylyl cyclase. This enzyme is activated by a factor called Nitric Oxide which is released from the endothelial cells which lines the walls of the blood vessels of the penis. The endothelial cells, when receive signals from the brain, synthesize Nitric Oxide using an enzyme called Nitric Oxide synthase. Viagra targets the enzyme responsible for converting cGMP into GMP and blocks it. In this way level of cGMP is raised. Increased cGMP level then causes erection when sexual stimulation is provided.

The drug is potent against erectile dysfunction when administered half an hour before sexual interaction. Its effect of enhancing sexual arousal in men is seen to keep going on for four hours straight, a time duration for the formerly incapable genitals to sustain a powerful copulation. Available dose forms of the drug are 25 mg, 50 mg and 100 mg blue colored tablets with the dosage concentration engraved on the side of the diamond shaped pill. The drug is best used with appropriate sexual stimulation. Do not take the drug above the recommended maximum dosage limit of one per day. Do not take the drug with other vasodilator such as nitrate containing cardiac medications. Do not take the drug with erythromycin and protease inhibitors as they interact with the drug to change its effects. Do not take the drug if you have renal, hepatic or cardiac problems as these diseases might render the drug dangerous to the body. Possible side effects to be aware of are diarrhea, dizziness, flushing, nasal stuffiness, runny nose, bluish vision and loss of hearing. If such effects remain for more than a couple of hours, contact your doctor and cease using the drug.
