Cialis ®
What is Cialis (tadalafil)?
Cialis is in a class of medications known as PDE-5 inhibitors, which are used
to treat cases of male impotence. Elli Lilly and Icos are currently marketing
Cialis in the UK and other EU countries.
How does Cialis (tadalafil) work?
Cialis acts in the same way as Viagra, by blocking an enzyme called phosphodiesterase-5,
or PDE-5. This helps the smooth muscles in the penis relax and widen, which
allows for more blood to enter. As a result, you gain erections faster and
easier with Cialis.
How well does Cialis (tadalafil) work?
Cialis is approved in these markets for the treatment of mild to severe ED
at both 10 and 20 mg doses. The labels in each of these markets indicate
that the product should be taken prior to anticipated sexual activity and
without regard to food. Just like Viagra, sexual stimulation is needed for Cialis to
work. According to the European label, the efficacy of Cialis may persist
up to 24 hours after the pill is taken. In Australia the Cialis label indicates
efficacy up to 36 hours after dosing.
Clinical Data Overview
More than 4,000 men have participated in more than 60 studies that characterized
the safety and efficacy profile of Cialis. In primary efficacy studies involving
1,112 men (804 Cialis, 308 placebo) with mild to severe ED, up to 81 percent
of those treated with Cialis reported improved erections compared with 35 percent
of those taking placebo(1).
The most commonly reported adverse events were headache, upset stomach, nasal
congestion, backache, muscle ache, dizziness, and flushing. The adverse events
reported with Cialis were transient and generally mild or moderate. As with
other PDE5 inhibitors, the use of Cialis is contraindicated in patients who
are taking nitrates. It should not be taken by patients with certain heart
diseases for whom sexual activity itself is not advisable.
Remember that no medicine is for everyone. If you take any form of nitrates,
often prescribed to control chest pains, do not take Cialis. This combination
could cause an unsafe drop in blood pressure.
What's the normal Cialis (tadalafil) dose?
In Cialis clinical testing most men were administered one 10 mg Cialis or 20
mg Cialis tablet per day.
Are there any side effects with Cialis (tadalafil)?
The most common side effects reported with Cialis in the study were headache,
myalgia (muscle pain), dyspepsia (upset stomach following meals) and back
pain. The severities of these Cialis side effects were minimized with lower
doses of Cialis.
