How Long Does Sildenafil Last?

Several generic medications are manufactured based on sildenafil, including Viagra and Cenforce. They are available in a variety of dosages and pharmaceutical forms.

In the 1990s, during a clinical trial of a medication intended for cardiovascular conditions, it was discovered by chance that sildenafil had a positive effect on male erectile function. Following this discovery, the substance was removed from the list of potential cardiovascular treatments, and research began into its use for erectile dysfunction. In 1998, Viagra was introduced—a medication that helped restore the sex lives of many couples. Today, numerous generic medications based on sildenafil are available in various dosages, allowing men to choose the option that best suits their needs.
