When considering purchasing Generic Viagra (sildenafil) from Mexico, it’s essential to understand the nuances and benefits associated with this option. Many people look to Mexico for more affordable alternatives to medications that are typically more expensive in the United States and other countries.
Statistics indicate a growing trend of Americans purchasing medications from Mexico. According to a study by the American Public Health Association, approximately 800,000 to 1 million Americans purchase prescription drugs from Mexican pharmacies each year. This number is likely to increase as more people seek cost-effective alternatives to high-priced medications in their home countries.
Mechanism of Action
To understand how Viagra works, we need to discuss the role of an enzyme called PDE5. This enzyme is responsible for breaking down a substance called cGMP, which helps relax the smooth muscles in the blood vessels, allowing increased blood flow. When Sildenafil comes into play, it inhibits PDE5, resulting in higher cGMP levels and improved blood flow. Consequently, this facilitates the process of achieving and maintaining an erection.
Viagra is a well-known player in the ED treatment arena. Some other popular options include:
- Avanafil (Stendra)
- Tadalafil (Cialis)
- Vardenafil (Levitra)
