Viagra has become a byword not only among patients with erectile dysfunction but also among adults who use the drug for entertainment purposes. The popularity of Viagra is not surprising considering that it is the first erectile dysfunction drug to be approved by the US Food and Drug Administration. However, there might be some competition. Cialis is another erectile dysfunction drug manufactured by Lilly Icos. Millions of people all over the world are suffering from impotence and Cialis is expected not only to fill the gap but to rival Viagra as the top erectile dysfunction drug. There is an estimated 175 million people worldwide suffering from the symptoms of erectile dysfunction and only a small portion are using Viagra. (To find prices and to buy cialis online please view the right menus) Viagra already has a foothold in the market but Cialis is not far behind. Here are some of the reasons why Cialis can rival Viagra as an erectile dysfunction drug.
• Cialis, like Viagra, works by blocking the PDE-5 or phosphodiesterase 5 enzymes and increasing the flow of blood in the penis. This results to an erection which lasts for a longer period, until the sexual act is completed.
• Cialis is widely marketed and can be bought with prescription in various countries including Germany, Finland, UK, Australia, Sweden and Denmark.
• Cialis works fast and for some men it can take effect 16 minutes after ingestion in comparison to Viagra which usually takes effect an hour after ingestion. While Viagra takes effect for several hours only, the effect of Cialis can last for 24 hours and even up to two days.
• Cialis stays in the body longer compared to Viagra which has a half-life of four hours. The 17 hours half life of Cialis means there exists 25% of the drug in the body even after 35 hours of taking in it. This is the reason why Cialis is called a weekend pill. And since it stays in the body longer, a person can still achieve and maintain an erection even after 36 hours.
• Cialis, unlike Viagra which is best taken on an empty stomach, does not interact with alcohol or food so you can still eat a hearty dinner before the big night. This means you can act like a normal person without being inhibited by the erectile dysfunction drug you are taking in.
Cialis is an effective erectile dysfunction medicine that can rival the already-established Viagra. However, you have to check with your doctor if Cialis is the right medication for you so you can maximize its effects and minimize the side effects.
