What is sildenafil?
Sildenafil is a prescription-only medication belonging to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. Sildenafil is used to treat Erectile Dysfunction (ED) in adult men. ED is a common condition where a man is unable to get or keep an erection. Approximately 50% of men will suffer from ED in their lifetime. ED can be caused by an advancing age, stress, anxiety, alcohol and certain drugs.
How does sildenafil work?
Sildenafil blocks the action of the naturally-occurring PDE5 enzyme. PDE5 is responsible for restricting blood flow to the penis. By blocking the action of PDE5, blood flow to the penis increases, therefore helping the patient obtain and maintain an erection.
For sildenafil to work, the patient must be sexually aroused or stimulated.
Sildenafil is not indicated for use in women.
What is the difference between sildenafil and Viagra?
Viagra and sildenafil are the same medication. They both work the exact same way and are equally as effective. The only difference is that Viagra is the specific brand of sildenafil whilst sildenafil is a generic medication. This means sildenafil is generally cheaper than Viagra as you are not paying for the brand.
