Cialis

Cialis is one of the pills that has recently started being sold in the United States to treat male impotence. In fact, the Cialis drug is only the third of these pills to be released, after Viagra and Levitra. The Cialis impotence drug is marketed by the Eli Lilly Co. for the worldwide market. It first was released in the United States in December of 2003. Cialis is known as the weekend pill as a result of its 36 hour effect. Cialis is also known by the drug name Tadalafil. The drug is taken in pill form and the pills are either five, ten or twenty milligrams, being yellow and oblong shaped.

The way that Cialis works is by inhibiting an enzyme that is mostly found in the smooth muscle of the penis. Cialis is roughly five times as effective as Viagra for a given weight of pill (so a twenty milligram Cialis pill has about the same effect as a one hundred milligram Viagra pill). Because of the method of action that works by inhibiting an enzyme Cialis should not cause someone to have an erection unless they are sexually stimulated in the first place. The other place that the enzyme which is influenced by Cialis is found is in the lungs, and Cialis is current being tested for the purpose of treating pulmonary hypertension, making it easier for people to breathe.

Lots of people are looking to buy Cialis: generic Cialis, cheap Cialis 20mg pills, etc. There is also the debate of which one is better: Cialis vs Viagra. Cialis and Viagra operate according to the same kind of chemical mechanism, however Cialis works on a different time schedule. With Viagra you take the pill once a day between thirty minutes and four hours before having sexual intercourse, while with Cialis you take the pill once for a thirty six hour period. Cialis side effects are generally things such as headaches, back pain, muscle aching, flushing, indigestion and a runny nose. Vision impairment is believed to be a possible side effect for some diabetics and there are ongoing studies to determine whether this is true or not. You can read various opinions on the Viagra versus Cialis debate on a Cialis forum; however it is necessary to advise that you do not buy Cialis online. The cheapest Cialis might not be such a great deal if you find that you have been deceived by a disreputable Cialis online dealer, so get your Cialis from an actual pharmacy.
