Viagra is a popular oral medication used to treat erectile dysfunction (ED). However, what is the science behind this drug?
Viagra works to treat ED by improving the rate of blood flow into your penis. It does this by blocking the action of a chemical called PDE5 that normally breaks down cyclic GMP. This allows cyclic GMP to keep working longer, which improves your ability to get and maintain an erection.
How Does Viagra Work?
Viagra works to treat erectile dysfunction (ED) by increasing blood flow to the penis. It does this by blocking a chemical called PDE5, which breaks down cGMP, a natural chemical released during sexual stimulation that causes an erection.
During sexual arousal, the nerves in your brain cause cGMP to be released into your penis. This causes the smooth muscle in your penis to relax, allowing blood to enter.
This helps to form an erection that is firm and long-lasting. However, if you take too much of this drug, you may lose your erection and feel an uncomfortable sensation. This is a common side effect of Viagra and can be treated by taking the medication less often or by lowering your dosage.
When you take Viagra, it enters your body quickly and starts to work after an hour. You can take it any time from 30 minutes to 4 hours before you plan to have sex, but it is best to take it at least 1 hour before sex.
Some men find that the medication works more quickly if they take it on an empty stomach. You should also avoid eating any high-fat foods and beverages while you are taking this medicine, as they can slow down how well it works.
If you are taking this medicine with certain other drugs, talk with your doctor about the possible drug interactions that could occur. Some drugs can make it harder for your body to process the Viagra, which can lead to serious side effects.
You should also tell your doctor if you have kidney or liver problems, as they may affect how well the drug works. They may also be able to tell you about other medications that you should avoid while you are taking Viagra.
Another important consideration is that you should not take this medication if you have an allergic reaction to it. If you have an allergy to sildenafil, other forms of this drug, or any of the other ingredients, call your doctor and let them know right away.
Some people have reported that the medication makes their genitals swell, but this was not a common side effect in studies. You should tell your doctor if you have swelling of your genitals when you take this drug, as it can be dangerous and need to be treated right away.
What Causes Erectile Dysfunction?
A person’s erectile dysfunction (ED) can be caused by many different things. These include diseases and conditions that affect the blood supply, nervous system, and endocrine system. Some of these are serious health conditions, while others are not.
ED is common in men, especially older men. It is estimated that half of men between the ages of 40 and 70 will experience erectile dysfunction at some point in their lives.
Your doctor can help you diagnose ED and treat it when it occurs. They will look for symptoms and test your body to find out the cause of ED, such as a blocked blood supply or nerve damage.
Medical causes of erectile dysfunction are often treated with medications or other treatments. These include phosphodiesterase (PDE)-5 inhibitors, such as sildenafil or tadalafil, that increase blood flow to the penis and help produce an erection. These medications can be prescribed by your doctor, as long as you are not taking any other medicines that may interact with them.
Other medical causes of erectile dysfunction include vascular disease such as atherosclerosis, kidney disease, diabetes, and low testosterone. A man can also suffer from a condition called Peyronie’s disease, where the blood vessels in the penis become narrowed and blocked, which prevents an erection.
Psychosocial causes of ED include depression, anxiety, stress, lack of sexual stimuli, and performance anxiety. These can cause an erection to stop, or be difficult to achieve, and can have a significant impact on your daily life and your relationships with other people.
If you are suffering from a psychological problem that is affecting your erectile function, talk to your GP about seeing a trained counsellor. These services are available for free on the NHS, or you can pay to see someone privately.
Your doctor will then talk to you about the type of treatment that best fits your needs and budget. Depending on the causes of your ED, your doctor may prescribe oral medication such as sildenafil or vardenafil or refer you to a urologist for injection therapy.
If your ED is caused by a health condition, such as diabetes or kidney disease, you may need to undergo surgery to restore proper blood flow to the penis. This is called a surgical penile prosthesis or a penile implant. The procedure is a relatively simple and painless operation, but it can be expensive.
How Does Viagra Work to Treat Erectile Dysfunction?
Getting and maintaining an erection can be challenging for men with erectile dysfunction (ED). Viagra, and other ED drugs, help by increasing blood flow to the penis. This is important because the spongy erectile tissue of your penis can become clogged by blocked blood vessels.
Your body can also produce a chemical called cyclic guanosine monophosphate (cGMP) that relaxes certain cells in the erectile tissue of your penis. This cGMP increases the flow of blood to the penis, which causes an erection to form.
The cGMP chemical works in combination with an enzyme called PDE-5 to increase blood flow to the penis and help you achieve an erection. Other ED medicines work by blocking the PDE-5 enzyme so that more cGMP is released.
Some people who have pulmonary arterial hypertension (PAH; high blood pressure in the blood vessels that supply the lungs) also take sildenafil to help them have and keep an erection. This medication is often used in conjunction with other ED medicines, such as Viagra or Levitra.
Sildenafil and other phosphodiesterases (PDE) inhibitors work by blocking the enzyme PDE-5 from breaking down a molecule that helps blood vessels relax and widen, allowing more blood to flow through them into the spongy erectile tissues of your penis. Once the spongy erectile organ of your penis is full of blood, it expands and stiffens, causing an erection to form.
You can usually get an erection within one to two hours of taking a pill that’s available at apothekeschweiz24.com, depending on your body’s metabolism. Then, it’s up to you to maintain that erection long enough for sex.
If you’re using Viagra, don’t drink alcohol. This can decrease the effectiveness of Viagra and cause side effects. It’s also important to avoid taking other ED medications at the same time because these can cause drug interactions.
Talk with your doctor about how much of the drug you should use for best results. Your dosage will depend on your weight, health, and other factors.
Your doctor will check your health regularly to make sure that you’re not at risk for serious side effects from the medication. They may ask you to stop taking it if you experience any serious side effects or if you think you’re having a medical emergency.
What are the Side Effects of Viagra?
While Viagra is often an effective treatment for erectile dysfunction, it can also cause some side effects. These side effects are usually mild and go away on their own with time. But if you’re experiencing them, it’s important to call your healthcare provider right away.
The most common side effects of Viagra are headaches, flushing, and upset stomach. You’ll also want to watch for more serious side effects like a longer-lasting or painful erection or vision changes.
In most cases, the milder side effects can be treated with over-the-counter (OTC) or prescription medications that your doctor recommends. However, you should avoid taking these drugs if you’re allergic to them.
Some people may experience problems with their blood pressure after taking Viagra. This happens because the medication relaxes your blood vessels. This can lower your blood pressure and make you feel dizzy or lightheaded, or even cause you to faint.
If you have a history of low blood pressure or heart problems, talk with your doctor about whether Viagra is safe for you to take. You’ll also need to make sure that you’re not taking other medications, such as alpha-blockers, which can also cause low blood pressure.
You should also avoid drinking grapefruit juice while you’re taking Viagra. One study found that drinking grapefruit juice with Viagra caused slightly higher levels of the drug in your blood than it did when you drank the juice alone. It’s not known whether this could cause increased side effects or increase your risk for bleeding.
Your doctor might also recommend that you stop taking Viagra if you have a bleeding problem, such as sickle cell anemia or multiple myeloma. These blood disorders can increase your risk for priapism, which is a long-lasting and painful erection.
Having a peptic ulcer can also increase your risk for priapism, so you’ll need to discuss this with your doctor before you take Viagra.
Older men are more likely to have a higher level of Viagra in their blood after taking a dose than younger men do. Having this higher level in your blood can increase your risk of some side effects, so older men are generally prescribed a dosage that’s lower than the dosage given to younger men.
