Erectile dysfunction (ED) is a condition where a man is unable to achieve or maintain an erection sufficient for sexual intercourse. There are several treatments available for ED, including medications that work by increasing blood flow to the penis.

When a man becomes sexually aroused, the brain sends signals to the nerves in the penis, causing the blood vessels to relax and widen. This allows more blood to flow into the penis, causing it to become erect. In men with ED, the blood vessels may not be able to relax properly, leading to reduced blood flow to the penis and difficulty achieving an erection.

Medications used to treat ED, such as sildenafil (Viagra), tadalafil (Cialis), and vardenafil (Levitra), work by inhibiting an enzyme called phosphodiesterase type 5 (PDE5). This enzyme is responsible for breaking down a molecule called cyclic guanosine monophosphate (cGMP), which helps to relax the blood vessels in the penis and increase blood flow.

Filitra Professional is a medication used to treat erectile dysfunction (ED) in men. It contains the active ingredient Vardenafil, which is a phosphodiesterase type 5 (PDE5) inhibitor. Like other PDE5 inhibitors, Filitra Professional works by increasing blood flow to the penis, making it easier to achieve and maintain an erection during sexual stimulation.

By inhibiting PDE5, these medications help to increase the amount of cGMP in the blood vessels of the penis, allowing them to relax and widen. This, in turn, allows more blood to flow into the penis, making it easier to achieve and maintain an erection.

It's important to note that these medications only work when a man is sexually aroused. They do not increase sexual desire or arousal on their own. Additionally, they can have side effects and may interact with other medications, so it's important to talk to a healthcare provider before using them.
