Tadalafil (Cialis).
Tadalafil (Cialis) was approved by the FDA in November 2003. This has been the third pill for erectile dysfunction treatment after the Viagra and Levitra.
Although Cialis is chemically unrelated to Viagra or Levitra, the pharmaceutical mechanism is similar to the above medicines. Like these other selective enzyme inhibitors, Cialis makes penile smooth muscle to relax, and allow increased amounts of blood to flow readily
into the penis and cause or enhance erection. In comparison to Viagra or Levitra, Cialis provides a far longer period of action, since it remains in the blood stream up to thirty six hours after use. In fact, the drug is known as "the weekend pill", because unlike the other two selective enzyme inhibitors, Cialis can be taken twelve hours before the sexual intercourse and the duration of action lasts at least twenty four hours. The medicine reacts within thirty minutes. However, it does not cause an automatic erection, without previous sexual stimulation. Studies have shown that 75% of men after taking 20mg can be benefited by the use of tadalafil.
Cialis is readily available either in brand or generic preparations. Nevertheless, counterfeits or pills with incorrect strength have been reported being sold on the internet. The buyer must be cautious, because such tablets may be proved ineffective or dangerous. In general, selective enzyme inhibitors must be purchased only from authorized pharmacies, since due to their popularity; they sell very easily and may tempt any irresponsible trader or manufacturer to make a quick profit from them.

Recommended dose for Tadalafil(Cialis).
The recommended dose is 5 or 10mg taken, before the anticipated sexual activity and without regard to food. In those patients, in whom 10mg of tadalafil do not result in adequate erection, 20mg can be tried. The above dose should not be exceeded on a daily basis.
Precautions related to Tadalafil(Cialis).
Like Levitra, Cialis must not be taken with any of the drugs called alpha-blockers which are used in treatment of prostate enlargement or high blood pressure, unless a physician's recommendation is different.
Men with a medical history of recent heart attack, stroke or chronic medical conditions, such as high or very low blood pressure and angina, should not take Cialis. In patients with kidney or liver disorders, the dose should be determined by a healthcare provider.
Cialis usage should not be combined with significant alcohol intake, especially if the person has already consumed more than four drinks. Otherwise, annoying or serious side-effects may occur. The latest include hypotension, headache, arrhythmias and dizziness.
Some specialists believe that grapefruit may interact with Cialis and maximize any side-effects, caused by the medicine.
Side-effects of Tadalafil(Cialis).
Headache is the most common adverse-effect of Cialis. However, it does not affect more than 15% of users. Other side-effects include palpitations, prolonged or severe dizziness, priapism, nausea, angina, swelling in the ankles and legs, shortness of breath, indigestion, orthostatic hypotension, back pain, muscle aches, flushing, runny or stuffy nose and temporary visual changes.
In general, the medicine is safe, if it is used properly and according to a doctor's guidance.
