Generic Viagra: an Overview

"generic Viagra" refers to the generic medicine equivalent to the original Viagra.

1. Composition and function

-the original Viagra contains sildenafil as an active ingredient. Generic medicines also contain sildenafil in most cases. Sildenafil acts by inhibiting the enzyme phosphodiesterase-5 (PDE-5), allowing for a greater flow of blood into the penis by relaxing the smooth muscles of cavernous tissue, facilitating erection.

2. Advantages of generics

Lower costs: generics are often cheaper than brand Viagra, as they do not have the research and promotion costs associated with the original drug. This allows them to be a more accessible option for many patients with erectile dysfunction.

Availability: in many regions, generics can be more widely available, as they can be manufactured by different pharmaceutical laboratories once the original drug patent has expired.

However, it is important that generic drugs are purchased through legal and safe sources, and always under medical supervision, as there may be variations in quality and purity if obtained from unauthorized sources.
