And those numbers may be higher — many don’t seek help for the condition due to embarrassment or shame. This new flood of nitric oxide activates an enzyme called guanylate cyclase, turning it into cyclic guanosine monophosphate (cGMP), and this relaxes the smooth muscles of the corpus cavernosum. Blood from the excited heartbeat can then rush in and fill the spongy tissue of the corpus cavernosum and produce an erection. A lack of sexual desire is another issue (libido) with its own set of treatments and medications.

The production of cGMP is necessary for the dilation and contraction of blood vessels. The enzyme PDE 5 destroys cGMP and does not let the blood flow properly. Tadalafil present in Cialis 40 mg blocks the action of PDE 5 and allows cGMP to be produced properly. As a result, a pressure is created in the penis that leads to an erection. Adcirca was more effective than placebo at improving exercise capacity based on one main study involving 406 patients with PAH, most of whom had class II or class III disease. Before treatment, these patients could walk an average of 343 metres in six minutes.

Viagra takes approximately 30 to 60 minutes to work, so you should take it about 1 hour before you plan to have sex. Taking Viagra more than 4 to 6 hours before you want to have sex may mean your Viagra will have no effect and you will need to wait until the next day to try again.

By controlling the enzyme, tadalafil helps to maintain an erection after the penis is stroked by increasing blood flow to the penis. Without physical action to the penis, such as that occurring during sexual intercourse, tadalafil will not work to cause an erection. Tadalafil is used to treat men who have erectile dysfunction (also called sexual impotence). Tadalafil belongs to a group of medicines called phosphodiesterase 5 (PDE5) inhibitors.

This inhibition boosts the level of cyclic Guanosine Monophosphate (cGMP), which increases penile blood flow and helps attain and maintain an erection when sexual stimulation occurs. Like other ED treatments, it takes about 30 minutes to take effect. Cialis differs from Viagra and similar medications, as its effect lasts for up to 36 hours, which is why it is sometimes referred to as a "weekend pill".

Furthermore, the longer half-life is the basis for tadalafil's daily therapeutic use in treating pulmonary arterial hypertension.

Amounts of Tadalafil in excess of 20mg have not been found to have any further positive effects, but have been seen to produce side effects more frequently (and with greater severity). If a 20mg dosage doesn’t have the required effect, then Tadalafil is simply not a viable treatment option, and others should be investigated.
