Japanese men who suffer from impotence will be pleased to hear that the second best selling erectile dysfunction medications in the world namely Cialis will be on sale soon in their country.

Eli Lilly that makes the drug Cialis, and is making an effort to increase its market share of pharmaceuticals in Japan especially as Japan is one of the largest consumers of pharmaceuticals in the world.

In fact the official date for the launch of Cialis was September 12th and it is estimated that Cialis have employed around 100 people to be dedicated to the sales of Cialis alone in Japan.

It is reckoned that around 30 percent of men in Japan suffer from either moderate erectile dysfunction or severe erectile dysfunction and the sales of both Viagra made by Pfizer and Levitra manufactured by Bayer have been extremely good in Japan.

Cialis is different from Viagra and Levitra in that it works for a much longer time thus making it far more practical for many men as they are therefore free from what Eli Lilly call "time pressure".

Cialis will work for about 36 hours compared to only four hours for Viagra and Levitra.

This is useful for men who are not exactly sure when they will experience a sexual encounter and thus they like to take a tablet to keep them going for the whole weekend.

In 2006 Eli Lilly sold almost $1 billion worth of Cialis around the world. Cialis is also a much copied drug and it is hoped that the arrival of the real thing in Japan will have a knock down effect on counterfeit copies that are sold on the black market.

Cialis such as Viagra, manufactured by Pfizer, Levitra produced by Bayer Health Care, and Intrinsa, a testosterone patch developed by Procter & Gamble to treat Female Sexual Dysfunction) is a prescription drug and should only be taken after doctor advice.
