Viagra 100mg

Erection medications primarily work by enhancing blood flow to the penis, which is essential for achieving and maintaining an erection. Here’s a breakdown of how these medications function:

Mechanism of Action

1. Inhibition of Enzymes: Many erection medications inhibit a specific enzyme in the body that regulates blood flow. By blocking this enzyme, the medications prevent the breakdown of a molecule that promotes relaxation of blood vessels.
2. Increased Blood Flow: When the enzyme is inhibited, levels of this molecule increase, leading to the relaxation of smooth muscles in the blood vessels of the penis. This relaxation allows for increased blood flow into the penile tissue.
3. Response to Sexual Stimulation: The medications do not cause an erection on their own; sexual arousal and stimulation are still necessary. When a man is sexually stimulated, the body releases additional signals that further enhance blood flow.
4. Engorgement of Penile Tissue: As blood fills the erectile tissues in the penis, it leads to engorgement and rigidity, resulting in an erection. The increased blood flow also helps to maintain the erection during sexual activity.
5. Duration of Effect: The effects of these medications can vary in duration, allowing for flexibility in sexual activity. Some medications are designed for quick action, while others provide a longer window of effectiveness.

Summary

In summary, erection medications work by inhibiting specific enzymes that regulate blood flow, leading to increased blood flow to the penis in response to sexual stimulation. This process allows men to achieve and maintain an erection, enhancing their sexual experience.
