Description

Cialis is a sexual health medication used to treat erectile dysfunction and premature ejaculation. The active ingredient in Cialis is tadalafil, which is a PDE5 inhibitor. PDE5 inhibitors are used to treat erectile dysfunction by inhibiting the action of the enzyme PDE5, which is responsible for the breakdown of cGMP in the penis. cGMP is responsible for the relaxation of smooth muscle in the penis, which leads to increased blood flow and an erection.

Cialis is available in oral tablet form in 25 mg, 50 mg, and 100 mg strengths. The recommended starting dose for most men is 50 mg, which can be adjusted based on response. Cialis should be taken at least 30 minutes prior to sexual activity. The maximum recommended dose is 100 mg.

Cialis has a half-life of 4-7 hours, which means that it stays in your system for this amount of time after you take it. The half-life of a medication is the amount of time it takes for the concentration of the drug in your body to be reduced by half.

Cialis is a PDE5 inhibitor, which means that it can cause side effects such as headaches, flushing, and dizziness. It is also possible that Cialis may cause hepatotoxicity, which is damage to the liver.
