Generic Viagra: an Overview
"generic Viagra" refers to the generic drug that has a mechanism of action similar to the original Viagra (sildenafil).
1. Composition and mechanism of action
-these generic medicines also contain active substances, such as sildenafil, which act by inhibiting the enzyme phosphodiesterase-5 (PDE-5). This allows cyclic monophosphate guanosin (cGMP) to accumulate in the smooth muscles of the penis, causing relaxation of these muscles and increased blood flow to the penis, facilitating erection.
2. Advantages of generic
Lower costs: generic drugs are generally cheaper than the original brand drug. This is because generic manufacturers do not have to invest in the initial research and development of the drug (which was already done by the company that created the original drug), and can produce it at lower marketing costs.
Availability: they can be more accessible in different regions, as they can be manufactured by multiple pharmaceutical laboratories.
3. Important considerations
Regulation and quality: although they are cheaper, they must comply with regulatory standards of quality and effectiveness. In many countries, health authorities control and authorize the production and sale of generic medicines to ensure that they are safe and effective.
Responsible use: as with the original Viagra, generic Viagra should be used under medical supervision. It should not be taken by people with certain serious heart disease, or in combination with certain medications that may interact negatively, as it can cause adverse effects.
