What is Viagra?
- Viagra is the brand name for sildenafil, a prescription medication used to treat erectile dysfunction (ED). Sildenafil belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. It works by increasing blood flow to the penis to help achieve and maintain an erection during sexual stimulation.
- Viagra was originally developed by Pfizer and approved by the FDA in 1998, making it the first oral treatment for ED on the market. Since its introduction over 20 years ago, Viagra has been prescribed to over 30 million men around the world. It is considered a revolutionary treatment that has helped normalize conversations around sexual health.
- The active ingredient in Viagra is sildenafil citrate, which inhibits the PDE5 enzyme that regulates blood flow in the penis. By blocking PDE5, sildenafil allows increased blood flow into the penis and relaxation of the blood vessels. This results in a firmer, more sustained erection during sexual activity.
- While Viagra is the most well-known brand name, sildenafil is also available generically and under other brand names like Revatio. Generic versions provide the same medical benefits as Viagra at a lower cost. However, there can be slight differences in things like inactive ingredients between brands.
How Viagra Works
- Viagra contains the active ingredient sildenafil citrate, which is a PDE5 inhibitor. PDE5 is an enzyme that breaks down a substance called cyclic guanosine monophosphate (cGMP), which controls blood flow to the penis.
- When sexual stimulation occurs, cGMP is produced in the penis, causing the smooth muscle cells to relax and allow blood flow into the spongy tissues. This blood fills the penis, causing an erection. PDE5 breaks down cGMP, reversing the erection.
- Viagra works by blocking PDE5 from breaking down cGMP so that blood can flow into the penis and cause an erection. Essentially, Viagra enhances the effects of cGMP and allows for improved blood flow and sustained erections.
The key points about how Viagra works are:
- It increases blood flow to the penis by inhibiting the PDE5 enzyme.
- By blocking PDE5, Viagra prevents the breakdown of cGMP to improve erections.
Effectiveness of Viagra
- Viagra (sildenafil) is an oral medication used to treat erectile dysfunction (ED). It helps improve the ability to get and maintain an erection in about 70% of men.
- Viagra works by increasing blood flow to the penis. When a man is sexually aroused, the brain sends signals to the blood vessels in the penis to relax and widen, allowing more blood to flow into the penis. Viagra helps enhance this natural process by preventing the breakdown of a chemical called cyclic guanosine monophosphate (cGMP), which causes the relaxation of the penile blood vessels.
After taking Viagra, the effects are usually felt within 30-60 minutes. The medication reaches peak effectiveness 1-2 hours after taking it. The effects typically last for about 4 hours. Viagra will not cause an erection on its own without sexual stimulation. The erection goes away after climax.
Side Effects
Viagra is generally well tolerated, but some side effects are possible. The most common side effects include:
- Headache – Headaches are reported in around 16% of men taking Viagra.
- Flushing – Facial flushing occurs in around 10% of users. This is due to Viagra’s effect on blood vessels and usually resolves on its own.
- Stuffy nose – Around 9% of men report nasal congestion after taking Viagra. This is also related to vasodilation. Using a nasal decongestant can help alleviate stuffy nose symptoms.
- Vision changes– Around 3% of users notice temporary vision changes such as blurred vision, increased sensitivity to light, or blue-tinged vision. These effects should go away within 2-4 hours. Seek medical attention if vision changes persist.
While usually mild, Viagra side effects can potentially be serious in some individuals. It’s important to be aware of possible side effects and talk to your doctor if any worrisome or persistent symptoms occur. With proper precautions, Viagra is generally considered safe for most men.
Warnings
Viagra should not be used by those who are concurrently taking nitrates for heart conditions, as the combination can cause a dangerous drop in blood pressure. Nitrates are found in many prescription medications that are used to treat angina (chest pain due to heart disease), such as:
- nitroglycerin
- isosorbide mononitrat
- isosorbide dinitrate
Conclusion
Viagra can be an effective treatment for erectile dysfunction (ED) in many men, but it does come with some risks and considerations. Viagra, known generically as sildenafil, is a prescription medication that works by increasing blood flow to the penis to help a man get and maintain an erection. For many men struggling with ED, Viagra can help improve sexual function and enjoyment.
However, Viagra is not right for everyone. Those taking nitrates or blood pressure medications should not take Viagra due to serious interactions. Other side effects like headache, flushing, vision changes, and stomach upset are possible. Viagra does not protect against sexually transmitted diseases. It should be used with caution in men with heart disease, kidney or liver problems, and other medical conditions.
Before trying Viagra, have an open conversation with your doctor. Together you can weigh the potential benefits and risks to determine if a prescription is appropriate for your individual situation and health status. Do not take Viagra without a doctor’s supervision. When used correctly under medical care, Viagra can help treat ED, but work closely with your provider to ensure it is the best option for you.
