Description
Description – Viagra Professional is the most up-today potent medication, the main aim of which is curing of erectile dysfunction. It is intended for an oral administration. It activates natural blood flow, which causes the penis enlargement and hardening when the peak of sexual activity is reached. The effect and properties of the drug completely correspond to the parameters of the classical Viagra 100 mg, while the cost of Professional 100 mg is much lower.
MECHANISM
- Viagra does not sexually arouse a man. It only works if a man is sexually stimulated.
- When you get aroused sexually, the nervous system in your penis’s erectile tissue releases nitric oxide (NO).
- The nitric oxide stimulates an enzyme that produces something called a messenger cyclic guanosine monophosphate (cGMP).
- The cGMP relaxes the smooth muscle cells. One result of this is that the arteries in your penis dilate and the blood can flow into your penis more easily.
- Another result is that the erectile tissue itself fills with blood. Both of these process result in an erection.
- Viagra works by maintaining the level of cGMP in the smooth muscle cells of erectile tissue.
