The branded drug Viagra (and generic unbranded Sildenafil drugs) are designed to help men get and keep an erection. However, it does not prevent premature ejaculation.
Studies suggest that it can reduce what is known as the refractory period – the span of time after orgasm when the penis stops responding to sexual stimulation. This can be a few minutes or several hours.
Erection
Viagra is the name of a brand-name prescription drug that treats erectile dysfunction (ED). It contains sildenafil citrate, which is an inhibitor of phosphodiesterase type 5. PDE-5 breaks down cyclic GMP, which dilates blood vessels in your penis and helps you have an erection. Viagra increases blood flow to your penis, so cyclic GMP can keep working for longer.
In some studies, people who took Viagra were able to delay ejaculation for up to eight hours after taking the medication. This can make sex last longer and may increase satisfaction during sex. However, the results from these studies are not conclusive and more research is needed.
You should not take Viagra with nitrate medications, including those used to treat angina. This includes prescription drugs such as nitroglycerin, and some over-the-counter medications such as l-arginine and yohimbine. Nitrates can cause a severe and sometimes painful erection that doesn’t go away, which is called priapism. Priapism can damage your penis, so you should seek emergency care right away if you have this problem.
In general, Viagra begins to work within 30 minutes of being taken and can last for up to 4 hours. But it is important to remember that it only works if you’re sexually aroused. If you’re not, the erection won’t last. Also, if you have a condition that causes an abnormal shape of your penis, like Peyronie’s disease, it may not work for you.
Ejaculation
If you have erectile dysfunction (ED), Viagra might help you get an erection for sexual activity. This drug contains sildenafil, which works by improving blood flow to your penis when you’re sexually aroused. It does this by blocking a chemical called PDE5 in your body. This chemical normally breaks down cyclic GMP, which is a chemical that relaxes and widens the blood vessels in your penis. This allows blood to flow more easily into the area in your penis called the corpus cavernosum, which makes you have an erection.
In clinical studies, Viagra has helped men with ED have and keep an erection for sexual activity. It also might help you achieve orgasm. However, this isn’t always the case for everyone. Sometimes, it takes a while for this drug to work. You should take your first dose of Viagra about an hour before you plan to have sex.
Some people may not be able to take this drug, including people who have certain heart conditions or high blood pressure. You should tell your doctor if you have a heart problem, stroke, or history of high blood pressure.
You can also have an allergic reaction to Viagra. Call your doctor right away if you have any signs of an allergic reaction. These include a rash, hives, or swelling of the face or throat.
Ejection
Most people know that viagra treats erectile dysfunction (ED) by blocking the actions of a chemical called PDE5. It also works in females to increase blood flow to the vagina and clitoris by widening the penis’s blood vessels. This increases arousal and orgasm, and may cause the woman to stay in an erection for longer periods of time.
For men who have trouble keeping an erection, sildenafil can be used to delay ejaculation. This can reduce performance anxiety and help them last longer in bed, which is often a major factor in ejaculation problems. It also helps them feel more confident during sexual intercourse and improves their ability to achieve a new erection after ejaculation.
However, this isn’t a solution for everyone. For example, if you have heart disease or a history of stroke or heart surgery, it may be dangerous to take Viagra. The drug can also interact with nitrate drugs, which treat angina. This can lead to a dangerously low blood pressure.
If you have a physical anomaly that affects your penis, such as bending or scarring, or you have a condition such as Peyronie’s disease, it isn’t safe to take Viagra. It can also be unsafe if you are pregnant or breastfeeding.
Resolution
Viagra is a prescription drug used to treat erectile dysfunction (ED). It works by improving blood flow to the penis when you’re sexually aroused. It does this by blocking the action of an enzyme called PDE5. This allows cyclic GMP to stay active longer, and it helps you have and keep an erection. Viagra works for about 4 to 6 hours.
Men have a period of time after they orgasm that’s known as the refractory phase. During this time, they are psychologically disinterested in sexual activity and physiologically unable to get an erection. The refractory period usually lasts a couple of minutes to 24 hours, and it’s part of the natural process of orgasm.
For women, Viagra may improve vaginal lubrication and orgasm by acting on the same mechanism as it does in males. It also increases blood flow to the clitoris. Viagra is available as a generic medication and is safe for most people to take. But it’s not a good choice for women with certain conditions, such as blood cell problems or heart disease.
People with these conditions have an increased risk of priapism, a long-lasting and painful erection. They also have a higher chance of bleeding in the penis. If you have these conditions, talk to your doctor before taking Viagra. He or she will recommend a different medication to treat your ED.
