About Cialis
Cialis is an oral drug for male impotence, also known as erectile dysfunction (ED). It works by dilating blood vessels in the penis, allowing the inflow of blood needed for an erection.
Cialis causes erections only during sexual excitement. It does not work in the absence of arousal and does not increase sexual desire.
As shown by studies involving 780 patients - Cialis is effective and safe in any etiology and severity of erectile dysfunction. One of the advantages of Cialis is its duration of action - the ability to get an erection in response to sexual arousal persists to 36 hours, so there is no need to plan the sexual intimacy. Cialis restores natural spontaneity of the sexual life.
The drug is easy to use. The recommended dose of Cialis is 20 mg. Cialis is taken before anticipated sexual activity, regardless of the meal. The drug should be taken at least 16 minutes before anticipated sexual activity. Patients may attempt to carry out sexual intercourse at any time within 36 hours after ingestion. The maximum recommended frequency of administration - 1 time per day.
In December 2003, the Food and Drug Administration approved Cialis for sale in the United States as the third ED prescription drug pill (after sildenafil (Viagra) and vardenafil (Levitra)). Cialis 48-hour effectiveness earned it the nickname, "The Weekend Pill"; like sildenafil and vardenafil, tadalafil is recommended as an 'as needed' medication. Cialis is the only one of the three that is also offered as a once-daily medication.
Moreover, Cialis was approved in May 2009 in the United States for the treatment of pulmonary arterial hypertension and is currently under regulatory review in other regions for this condition.
