Not many anti-impotence drugs have guaranteed safety and efficacy. Of these only a few choices, the drugs most preferred by men around the world are those whose effects can make them erect all weekend.
Currently there are only 4 types of drugs that are guaranteed to be used as anti-impotence by the Food and Drug Administration (FDA). The four of them are Cialis, Levitra, Staxyn, and whose name is very popular because it has been around since 1998, namely Viagra.
Even though it is the most popular cialis generika apotheke, that does not mean that Viagra is the most sought after by men in the world. The drug with the generic name sildenafil produced by Pfizer did dominate the market, but in recent years its dominance has begun to waver.
In March 2011, IMS Health data recorded that Viagra was only able to control 39 percent of the anti-impotence drug market. Tadalafil developed by GlaxoSmithKline and marketed by Eli Lilly under the brand Cialis has succeeded in taking over the market dominance of Viagra by 41 percent.
Although listed as a pioneer of the anti-impotence drug class of PDE-5 inhibitors, Viagra (sildenafil) finally had to give up on its competitor, Cialis (tadalafil). Not without reason, in some ways Cialis does have advantages over Viagra.
When using Viagra, impotent men must take medication every time they want to make love and the effect will wear off in the next 4 hours. While quoted from WebMD, Friday (15/3/2012), Cialis works a little slower but the effect can last up to 36 hours!
For those who don’t need the effects too long, Cialis also provides more dosage options. If the effect for 36 hours can be obtained with a dose of 10 mg and 20 mg, then with a lower dose of 2.5 mg and 5 mg the duration of the effect will be the same as Viagra, which is for one sex.
Thanks to its longer lasting effect, Cialis has actually shifted the dominance of Viagra since 2005, especially in France. In that country, Cialis is quite popular with the nickname ‘ Le Weekender ‘ or the weekend complement because its effects can last throughout the weekend.
