Pfizer's Mission: An Impotence free world

The strength of the intimate relationship is strongly affected by the process of sexual intercourse. Sexual intercourse is the source of delightful physical connection for both the partners of the couple. If the disease of impotence attacks the man, all the pleasures achieved by the healthy sexual relationship are lost. The chances of acquiring impotence increase if one has been living in noise pollution and air pollution areas. The introduction of anti-impotence drug by Pfizer pharmaceuticals, Viagra, has stirred a revolutionary change in the sex life of countless men who were crippled sexually by the disease of impotence. Viagra has enabled the patients of impotence to enjoy once again the ecstatic moments of sexual intercourse. Viagra is a death sentence for the disease of impotence.

How Viagra performs the trick:

The amazing phenomenon of erection revolves around the availability of a factor called cGMP. This factor, synthesized by the breakdown of GTP, has a vasodilator action. When a person is sexually stimulated, guanylyl cyclase, an enzyme, breaks GTP into cGMP. cGMP causes the dilation of the vessels of the penis. Small holes are formed in the walls of the vessels due to their dilation. Blood escapes through these holes and finds its way into the spaces located in the spongy tissue, carpus cavarnosum, of the penis. The spaces filled with the blood build up turgor pressure in the spongy tissue which has its manifestation in the form of erection. Unfortunately the level of cGMP falls in the victims of impotence, resulting in flaccid penis. Viagra plays its erectile role by blocking the enzymes responsible for demolition of cGMP. Thus effective level of cGMP is maintained in the penis.

Your daily schedule to take Viagra:

Daily dosage of Viagra should not exceed one tablet of the blue pill or else drug toxicity might result in unexpected and even in some cases, life threatening conditions. Initially, the starter is required to take 25 mg tablet per 24 hours time, later on if the dosage proves not to be that much effective, could be increased to 50 mg and then to 100 mg if required. The drug is to be taken anytime half an hour before sexual interaction during which it prepares the body for necessary drug actions. Half an hour after the onset of its effect on the body, its effects could be made use of for four hours. Sufficient sexual stimulation is necessary if the effects are to be experienced to maximum. Protease inhibitors, nitrate containing heart medications and the antibiotic by the name of erythromycin are strongly contraindicated drugs in case of Viagra and are to be avoided no matter what the case might be.

Potentially fatal symptoms while on Viagra:

Due to drug action on tissues other than PDE5, side effects of the drug are quite observeable. Possible ones include cyanotic vision and hearing decline as important factors. Other might be dizziness, diarrhea, nasal congestion, prolonged painful erection and runny nose in some of the reported cases. If these effects do not diminish in a couple of hours, seek medical guidance immediately.
