Cialis challenges Viagra

By: Stephen Robert

Gene therapy for erectile dysfunction may just be the next big thing in the medical world after the stupendous success of oral pills like Viagra and Cialis. The gene transfer of relevant molecules involved in the regulation of penile erection has emerged from just an imaginable possibility to an exciting reality.

Clinical studies are already being done for more than a decade of investigating the role of potassium channels in normal and abnormal erection physiology. The concept here is to improve natural erections by modifying cell to cell signaling responsible for smooth muscle relaxation. This first clinical step is to demonstrate that the vector with the coded information for the maxi-K channel sets up in the penis without causing systemic side effects. The next area of clinical testing will be to evaluate efficacy in men with erectile dysfunction.

Erectile Dysfunction has seen many effective drugs like Viagra, Cialis, and Levitra and has changed many lives. Viagra had been the magic pill till date for treatment of Erectile Dysfunction. But since the approval of Cialis in 2003, Viagra has had stiff competition from Cialis. In January 2005, Cialis, Tadalafil became the leading ED treatment in France. It is also performing very well in other countries, including the United Kingdom, Italy, Germany, United States, Canada, Australia, Mexico and Brazil.

Cialis, Tadalafil was the second PDE5 inhibitor drug to become available in Europe. It is currently marketed in approximately 100 countries including the United States, Australia, Brazil, Mexico, Canada and across Europe and Asia.

The success of Cialis over Viagra could be attributed to the fact that Cialis works for a longer time. It works upto 36 hrs. and can be taken an hour before sexual intercourse. Cialis gives a man and his partner to choose the moment for intimacy that's right for them. It has even earned the name of the weekender attributing to its 36 hrs effect.

Since its approval in the United States in November 2003, Cialis has increased its share of total prescriptions every month in the U.S too.

Cialis can be taken without regard to food. The absorption of Cialis is not reduced by food, including high-fat foods. Cialis is currently available in approximately 90 countries. Nearly three million patients worldwide have been treated with Cialis since its first introduction in February 2003. Cialis is changing the way doctors and patients think about treating ED by offering two important benefits: a 36-hour window of opportunity for intimacy and the ability to take the tablet on an empty stomach or with a meal, without concern that high-fat food will reduce the absorption of the medicine.

Cialis is available online with various sites and one can buy Cialis online. There are many Cialis pharmacy which sells generic versions of Cialis online. Before buying from any of these cheap cialis pharmacy, one must ensure that they are certified by the VIPPS. It is strongly recommended to buy Cialis only after proper consultation from the doctor and from certified online pharmacies and not just buy because cheap Cialis is available on a particular online pharmacy which may not be certified.
