Viagra®

Today, almost half of the male population from 40 to 70 years old suffers from such diseases as premature ejaculation, erectile dysfunction and male impotence. Due to the globalization and technological development in the medical sphere, a lot of pharma companies provide the great variety of the medications for the treatment of male impotence.

The first company which managed to invent Sildenafil - the chemical name of Viagra – was Pfizer. Pfizer is one of the biggest multinational companies in the world. Its products are marked by high quality and great efficiency. This pharmaceutical corporation had the aim to invent the innovative medicine for the cure of angina pectoris (cardiac disease) and high blood pressure. But the tests of Viagra showed that Sildenafil influences the sexual capacity in men. Soon, this medicine gained the great success among men who are incapable to maintain the stable erection and to enjoy the normal sexual life.

Nowadays, Viagra is known to everybody due to its miraculous effect on the male organism. A lot of pharmaceutical companies which take the leading positions in the pharma world invent, manufacture and export the analogs of Viagra with the same active component which provides the stable erection in men.

Pharmacological action

The active ingredient of the medicine Sildenafil 100 mg increases the blood flow to certain parts of the penis and relaxes its smooth muscles. The muscles relaxation awakes the stable erection in men. The reverse reaction occurs with the chemicals which break down in the body with another substance called PDE 5 (phosphodiesterase type 5). When Viagra blocks this substance, it remains in the male organism and prevents the constriction of the muscles. The increased pressure of blood vessels remains for a long period and this process makes a man sexually capable. The erection does not occur by itself after the medicine intake. It is possible in case of the sexual arousal in men.

Indications

Before Viagra intake doctors recommend to ask for the medical consultation. The dosage of the drug must be established by a doctor concerning the health characteristics of the patient. If you have the history of liver, kidney or heart diseases or you suffer from the high blood pressure, tell your doctor before the prescription of the dose.

They are: headache, dizziness, running nose, diarrhea or flushing of the face. Such side effects will last in an hour after the medicine intake. But if you experience back pain, sudden loss of vision, painful erection which lasts more than 4 hours ask for the medical cure.
