Sildenafil, often still referred to as generic Viagra, is the active ingredient found in Viagra. While Viagra also contains small amounts of inactive ingredients that help give the pill its shape and aid digestion, sildenafil citrate is the component responsible for the medication’s therapeutic effects.
What Is Sildenafil?
The full medical name of Sildenafil is sildenafil citrate. It belongs to a group of medications known as PDE5 inhibitors. These drugs work by relaxing blood vessels and improving blood flow to specific parts of the body.
Sildenafil is most widely known for its role in treating erectile dysfunction (ED), a condition characterized by the inability to get or maintain an erection firm enough for sexual activity.
How Sildenafil Works for ED
Sildenafil helps treat erectile dysfunction by increasing blood flow to the penis during sexual stimulation. It does not cause an automatic erection; instead, it supports the body’s natural response to arousal.
The medication is typically taken 30 to 60 minutes before sexual activity, and its effects usually last for a few hours. Because of this limited duration, it is intended for use only when needed rather than as a daily medication for most patients.
Additional Medical Uses
In addition to treating erectile dysfunction, sildenafil citrate is also approved for the treatment of pulmonary hypertension (PH). This condition involves elevated blood pressure in the arteries of the lungs and the right side of the heart. By relaxing blood vessels in the lungs, Sildenafil helps improve blood flow and reduce strain on the heart.
Important Considerations
-
Sildenafil should only be used as prescribed by a healthcare provider.
-
It may interact with nitrates and certain heart medications.
-
Common side effects can include headache, flushing, nasal congestion, and dizziness.
Conclusion
Sildenafil is a well-established and effective medication for erectile dysfunction and pulmonary hypertension. By improving blood flow through targeted vascular relaxation, it helps many individuals regain sexual confidence or manage serious cardiovascular conditions. Always consult a healthcare professional before starting or adjusting any medication.
