Not a lot of anti-impotence drug that guaranteed the safety and efficacy. Of which only a few options, the drug most preferred by the men around the world is that the effect can make an erection throughout the weekend.
Currently there are only four types of drug use as an anti impotence guaranteed by the U.S. Food and Drug Administration (FDA). All four are Cialis, Levitra, Staxyn, and whose names are very popular because it has existed since 1998, which is Viagra.
Although the most popular, does not mean that Viagra is the most wanted man in the world. Generic name sildenafil drug manufactured by Pfizer is indeed time to dominate the market, but in recent years its dominance began to be moved.
On March 2011, data recorded IMS Health Viagra just able to master 39 percent of anti-impotence market. Tadalafil developed by GlaxoSmithKline and marketed by Eli Lilly under the brand name Cialis success would take over the market dominance of Viagra with 41 percent.
Although listed as a pioneer of anti-impotence drug class of PDE-5 inhibitors, Viagra (sildenafil) finally had to give up on its competitors namely Cialis (tadalafil). Not without reason, in some respects Cialis does have advantages over Viagra.
When taking Viagra, men who have impotesi to take medicine every time I want to make love and its effects will disappear within the next 4 hours. While quoted by WebMD, Cialis works a bit slower but its effects can last up to 36 hours!
For those who do not take effect for too long, Cialis also provides more options doses. If the effect for 36 hours can be obtained with a dose of 10 mg and 20 mg, then a lower dose of the 2.5 mg and 5 mg duration of the effect will be the same as Viagra for sex once.
Thanks to a longer lasting effect, Cialis has actually been shifting dominance Viagra since 2005, especially in France. In the country, Cialis is quite popular with the nickname ‘Le Weekender‘ or the weekend supplement because its effect can last throughout the holiday weekend.
