Who will win the erectile dysfunction (ED) Olympics, which is predicted to reach $6 billion by 2007?

The days of the Gladiator are back: only the coliseum has changed face with Erectile Drug Pharmaceutical companies fighting a Battle royal : The Three contestants are Pfizer's Viagra, GlaxoSmithKline & Bayer’s Levitra and Eli Lilly & ICOS' Cialis.


The current reigning King of the Ring- Viagra weighs in with yearly sales of $1.74 billion! (Sales for 2002) Levitra & Cialis are giving it a run for its money. All three have their own speed of reaction, duration of length and side effects profile. However, all three have the same mechanism, as they block the actions of PDE-5. This does not mean that the drugs are identical -- a close look reveals key differences between them.


Viagra has the weakest profile: It has to be taken on an empty stomach, takes 30 minutes to a hour to react, lasts for 4 hours and its side effects include temporary changes in vision, headaches and flushing. Levitra is a slight improvement over Viagra: It can be taken with food, only takes 25-30 minutes to work, lasts up to 5 hours and has side effects at a lower incident rate.


Cialis emerges as the winner as it can do what the other two can do but only faster and more effectively. A single pill can work as soon as after 16 mins and remains effective for up to 36 hours. It also lacks the visual side effects as that of Viagra.,Br>


Buy Cialis for its spontaneous reaction! You do not have to plan your sexual activity for it to work.
