Cialis is an effective treatment of erectile dysfunction, which is a man’s inability to achieve an erection when aroused or sustain an erection during sexual activity or intercourse. Erectile dysfunction can affect a man at any time in his life; though as men grow older the chances of having erecting dysfunction increase. Impotency as erectile dysfunction is sometimes known can be caused by health issues such as arterial hypertension or psychological problems like depression or stress. On in ten men are thought to be affected by erectile dysfunction at some point in their lives, and it can be a distressing and often embarrassing condition.
Tadalafil is a drug designed to enable a man to achieve an erection that can last through intercourse. Tadalafil has been used by millions of men and its effectiveness and popularity has meant that Tadalafil prices have fallen since it was first introduced.
PDE5 Enzyme Controlled by Taladafil to Improve Erections
Tadalafil is a PDE5 inhibitor which is similar in structure to the active ingredients in Viagra and other erectile dysfunction medications. The difference is that Tadalafil takes far longer to be rendered inert in the human body; this is what is called its half-life. The drug that is sold by the name Viagra, sildenafil citrate has a half-life of around four to five hours. Tadalafil has a half-life of around sixteen to seventeen hours. This means that the drug can be taken on a daily basis instead of half an hour prior to intercourse, which is the case with sildenafil citrate and other erectile dysfunction pills. Cialis costs roughly the same as other ED pills.
As with all erectile dysfunction medications Tadalafil will only become effective when the man is sexually aroused as the chemicals which the drug acts on are only present during arousal. Tadalafil cost will vary depending on where it is purchased.
When a man becomes sexually aroused a chain of chemical reactions in the blood cause the blood vessels to dilate which increases blood flow to the muscular tissues that run the length of the penile shaft, known as the corpa cavernosa. The increased blood flow causes the copra cavernosa to swell and stiffen; an erection. Erectile dysfunction is when the blood vessels remain contracted due to the natural enzyme called phosphodiesterase type 5, or PDE5. Tadalafil is a PDE5 inhibitor which deactivates the enzyme and allows the penis to become erect.
Tadalafil prices may vary dependant on the source, but it is widely available either online through pharmacies where you can order Cialis prescriptions, over the counter or from a doctor and can help men who suffer from erectile dysfunction carry on with a normal sex life.
