Effect of Cialis
In contrast to similar drugs used to treat erectile dysfunction like Viagra, the effect of Cialis may last up to 36 hours, which enables you to feel more relaxed in bed.
Following ingestion, the active ingredient in Cialis is quickly absorbed within the digestive tract. The therapeutic concentration of tadalafil (i.e., active ingredient) is fully absorbed in blood within 30 to 120 min.
Effects of Cialis are not known to be influenced by concurrent food consumption. However, evidence from clinical studies suggests that ingestion of too many fatty foods and alcohol can slow the absorption of tadalafil within the gastrointestinal tract.
The half-life of tadalafil is on average 17.5 hours. Tadalafil can be detected in the inactive form throughout the digestive system (up to 65%) and in urine (35%).
Cialis dosage & uses
Instructions for the use of Cialis are as follows:
- with an active sexual life (i.e., sex occurs >2 times per week) take 5 mg per day. Cialis should be taken at the same time each day irrespective of concurrent food consumption;
- with low sexual activity (i.e., ≤2 times per week), one tablet of Cialis should be taken at a dosage of tadalafil equal to 20 mg approximately 30 to 40 minutes prior to engaging in sexual intercourse.
For the complex treatment of inflammation of the prostate, Cialis may also be taken in 5 mg doses once a day.
