Vs Viagra ©
Viagra and Cialis are based on the same principle
and work the same way. However, there are some differences between
to the products:
Viagra was the first FDA approved drug for the treatment
of erectile dysfunction. Viagra is produced by Pfizer. Cialis, on
the other hand was the third erectile dysfunction medication approved
by the FDA for sale in the United states. Cialis is produced by
Lilly.
Perhaps the main difference, is that Cialis continues
to work for 36 hours while Viagra works for only 4 hours based on
the medical information provided by the respective manufacturers.
There are also claims that Cialis works more quickly
than Viagra- half an hour for Cialis compared to an hour for Viagra.
Viagra is a registered trademark of Pfizer.
