Erectile dysfunction is the inability to get an erection or maintain an erection during sexual activity. It is a condition that affects millions a year, with on every ten men being affect on average. Though men over sixty are four times more likely to be affected than men in their forties, it can affect men of all ages. In the majority of case erectile dysfunction, or impotence, is caused by health problems like high blood pressure, but it can also occur due to psychological issues such as depression or stress.
Many men who suffer from erectile dysfunction chose to purchase Cialis without prescription, a highly effective drug that enables men to achieve strong and lasting erections. To purchase Cialis a prescription used to be required from a doctor or mental health professional, though now men are able to purchase Cialis no prescription required either from a pharmacy or online from certified websites.
The reason many men purchase Cialis is that it is a pill taken daily, rather than just before sexual activity. This is because the key component of Cialis, the drug called tadalafil, has a longer half-life than other erectile dysfunction treatments. Half-life is the time it takes for the chemical to be broken down by the body and become inactive. Cialis takes around sixteen hours to become inactive in the blood; on the other hand Viagra and Levitra, two other erectile dysfunction treatments, take around four hours.

The longer half-life of Cialis means that lower dosages of the drug can be taken on a daily basis to maintain a background level in the blood, enabling men to have erections when they choose. Tadalafil is a PDE5 inhibitor and the PDE5 enzyme is only present when a man is sexually aroused, so the drug only takes effect during arousal.
Erectile dysfunction is caused by restricted blood flow to the penis. This is caused by the PDE5 enzyme which constricts the arteries and blood vessels leading to the penis. The tadalafil in Cialis inhibits the PDE5 enzyme and renders it inert, thereby enabling the blood vessels to dilate and increase the flood flow to the penis, producing an erection.
Millions of men every year choose to purchase Cialis enabling them to have erections at times of their choosing, meaning they can pursue a far more natural and spontaneous sex life without the need to plan in advance for sexual activity or intercourse. There are several online pharmacies that offer sale Cialis pills.
