The purple pill viagra commonly refers to the generic version of Viagra, which is Sildenafil. While the color of the pill can vary depending on the manufacturer, the term “purple pill” is often used to describe Viagra or its generic counterparts due to the distinctive color of some of the generic versions. Sildenafil works by blocking the enzyme phosphodiesterase type 5 (PDE5), which is responsible for the breakdown of cyclic GMP (cGMP). cGMP helps relax the smooth muscles in the blood vessels of the penis, allowing them to expand and increase blood flow, which results in an erection when combined with sexual stimulation. However, it should be used with caution in individuals with certain medical conditions or those taking medications that could interact with sildenafil.
