Generic Cialis refers to generic tadalafil.

1. Cialis (CIALIS) and its active substance

-Cialis is a trademark containing tadalafil as an active substance. Tadalafil is a selective inhibitor of phosphodiesterase-5 (PDE-5).

-it works by relaxing the smooth muscles of the penis, allowing an increase in blood flow to the penis during sexual stimulation, facilitating erection.

2. Generic aspects

-generic tadalafil has the same pharmacological action as the Cialis brand.

-generic is generally cheaper than the original brand. This is because it does not have the costs associated with initial research and development, promotion and brand of the original version.

-however, it must be obtained from legitimate sources and under proper medical prescription, as, like the original brand, it can have side effects and contraindications. Some common side effects include headache, stomach discomfort, nasal congestion, and blurred vision.

It is important to remember that the use of erectile dysfunction medications should be monitored by a doctor, as they may interact with other medications or take risks in patients with certain underlying diseases.
