What you need to know about Viagra

Viagra is a drug that was developed to treat erectile dysfunction of any origin - organic, psychogenic or mixed. The product is available in the form of tablets.

How Viagra works

This drug helps to restore an adequate response to sexual arousal. In the structure of the penis there is a formation called the corpora cavernosa. It is this that provides an erection - an increase in the size and hardening of the penis during arousal. The natural mechanism by which an erection occurs is impossible if, during irritation, nitric oxide is not released in the corpus cavernosum of the penis. Under the action of this substance, a special enzyme, guanylate cyclase, is activated. As a result, the muscles of the corpus cavernosum become relaxed, and blood flow to the male genital organ increases. Sildenafil citrate - the active substance of the Viagra drug - helps the corpora cavernosa to relax, acting on it not directly, but enhancing the relaxing effect of nitric oxide. To take Viagra to be effective, you need sexual irritation.

Do not take Viagra

• People with heart disease
• Those who have anatomical defects of the penis - Peyronie's disease
• Patients with sickle cell anemia
• Men, who are under 18 years old

• With leukemia
• If there is a hypersensitivity to the drug or its individual components
• With gastric ulcer in the acute stage
• With cirrhosis of the liver and kidney failure

Cymeditine (a drug for the treatment of stomach ulcers), erythromycin, and ketoconazole (a drug for combating fungal skin lesions) reduce the kidneys' ability to remove the protein breakdown product, creatinine, from the body. These medicines also increase the concentration in the blood of sildenafil, the active substance of Viagra.

Simultaneous administration with nitrates can be fatal, since Viagra sharply enhances the hypotensive effect of these drugs. It is also life-threatening to take Viagra and drugs from the group of slow calcium channel blockers together. These are cinnarizine, nicadipine, verapamil and others. You can not take Viagra and beta-adrenoblocators (anaprilin, bisoprolol) together, as well as hypoglycemic agents for oral administration.

How to take Viagra correctly

The drug is drunk 1 hour before intimacy. The amount of the drug per dose is 50 mg (once a day). If a man tolerates Viagra well, and after taking 50 mg, the desired effect does not occur, the dose can be increased to 100 mg - this is the maximum single dose. It can also be reduced to 25 mg. In case of Viagra overdose, side effects become more pronounced. Treatment in such a situation is only symptomatic. Dialysis will not give the desired effect, since the active substance of Viagra very quickly binds to proteins in the blood plasma. Store Viagra in dry conditions out of the reach of children. Storage temperature - no higher than 30 * C.
