What is Cialis? Unveiling the Mystery

1. Functioning in the body

-Tadalafil is mainly used to treat erectile dysfunction (ED) in men. It works by inhibiting the enzyme phosphodiesterase-5 (PDE-5). This enzyme is responsible for degrading a chemical compound called cyclic monophosphate guanosin (cGMP) into the tissues of the penis. By inhibiting PDE-5, tadalafil allows cGMP levels to remain high. An increase in cGMP levels causes relaxation of smooth muscles in the blood vessels of the penis, allowing greater blood flow to the penis and, consequently, an erection.

2. Advantages and characteristics

-one of the advantages of Cialis is that it has a relatively long duration of action compared to other medicines for ED. It can have an effect for up to 36 hours, resulting in the popular denomination of "Cialis weekend".

-it has also been studied for use in erectile dysfunction associated with certain underlying diseases, such as diabetes or high blood pressure.

3. Precautions and contraindications

-it should not be taken by men who take nitrates (e.g. nitroglycerin), as the combination can cause a drastic drop in blood pressure.

-it may have side effects, including headache, muscle pain, heartburn, among others. In addition, it should be prescribed by a doctor and the recommended dosage should be followed, as an abuse of the medicine may have negative health consequences.
