Tadalafil and Sildenafil
Tadalafil is an oral drug that is used for treating impotence or better to say the instability to attain or maintain a penile erection. It is in a class of drugs called phosphodiesterase inhibitors that also includes Sildenafil. Erection of the penis is caused by the filling of the penis with blood. Filling occurs because the blood vessels that bring blood to the penis increase in size and deliver more blood to the penis, and, at the same time, the blood vessels that take blood away from the penis decrease in size and remove less blood from the penis. Both Sildenafil and Tadalafil, which have the same mechanism of action, are the leaders in this case. Sildenafil is an ED treatment sold under different names, the most famous one – Viagra. It was created by British scientists as a pulmonary arterial hypertension treatment and was brought to the USA by the company Pfizer. Sildenafil is used for erectile dysfunction, pulmonary hypertension and altitude sickness treatments and have shown amazing results in all cases.
Sexual stimulation that leads to an erection causes the production and release of nitric oxide in the penis. The result is relaxation of smooth muscles of arteries and blood flow to the tissues of the penis that causes an erection. Tadalafil has no effect in absence of sexual stimulation. The same characteristic is true for Tadalafil, but they are different in their activating time and duration of effect.
Tadalafil should be taken as little as 16 minutes before sexual intercourse and the effect will stay for up to 36 hours. Sildenafil is recommended to be taken an hour before intercourse and after that you will get 4-6 hours of enjoy.
