Erectile dysfunction is when a man is unable to get or sustain an erection. It usually happens because the arteries that carry the blood to the penis are too narrow. Vardenafil increases blood flow to the penis.

Its action is similar to that of sildenafil, or Viagra, but Viagra lasts between 2 and 4 hours, while Levitra lasts 4 hours. During a penile erection, the penis fills with blood. The blood vessels that supply the penis with blood expand, or dilate, and the vessels that take blood away from the penis contract. The two large chambers in the penis, known as the corpus cavernosa, fill with blood. As the blood accumulates in the penis, an erection results. They should not be taken with any kind of drink. The drug will not work unless the man is sexually aroused, so foreplay will normally be necessary.

Vardenafil can be taken with or without food, but drinking alcohol is not advised, as it reduces the chance of getting an erection. Alcohol can also increase the risk of adverse effects.

What Is Viagra (Sildenafil)?

Vardenafil belongs to a class of drugs called phosphodiesterase type-5 (PDE5) inhibitors. A PDE5 inhibitor stops PDE5 from constricting the arteries. By relaxing the arteries, vardenafil enhances blood flow when a man is sexually aroused. The active ingredient works on the chain of reactions within the penis during arousal. When a male is sexually aroused, nitric oxide is released into his penis, and this triggers a chain of reactions.

sildenafil Cardiovascular Disease

This causes an enzyme, guanylate cyclase, to produce cyclic guanosine monophosphate (cGMP). cGMP regulates the contraction and dilation, or expansion, of blood vessels that carry blood to and from the penis. The chemical reaction causes the vessels that supply the penis to dilate, while those removing blood from the penis contract. Phosphodiesterase-5 (PDE5), viagra daily another enzyme breaks down or destroys cGMP. When cGMP is destroyed, the blood vessels return to their normal size, effectively ending the erection. As with all medications, adverse effects and interactions can occur when using vardenafil. One in 10 men will experience headache.

In this way, it allows cGMP to work for longer. As a result, it helps prolong an erection. Vardenafil is available in tablets of 2.5 milligrams (mg), 5 mg, 10 mg, and 20 mg. The first dose is normally 10 mg. A 10-mg dose of vardenafil is approximately equivalent to 50 mg of sildenafil, or Viagra. In most cases, these disappear within a few hours. ringing in the ears, or sudden hearing loss swelling in the ankles, hands, or feet The patient should stop using vardenafil if these occur. This can lead to hives, difficulty breathing, and swelling of the face, tongue, and throat. If these symptoms appear, it should be treated as a medical emergency.

• Consult your doctor if you experience persistent erection issues.
• Do not share medication with others; it is prescribed for individual use.
• Regular check-ups are recommended for ongoing use.

Very rare side effects may include priapism, when an erection lasts longer than 4 hours. If an erection lasts too long, the individual should seek medical attention. Visual disturbances can happen when blood pressure drops in the eye. The individual may see a blue tinge to objects, and they may have difficulty distinguishing between the colors green and blue. Very rarely, there may be a sudden deterioration in vision in one or both eyes.

• Vardenafil 20mg is not suitable for individuals taking alpha-blockers.
• Patients with heart conditions should consult their doctor before use.
• Precautions are necessary for those with liver or kidney issues.

This can indicate a heart condition, an existing eye problem, high cholesterol, diabetes, or hypertension.

Pharmacotherapy for erectile dysfunction2010, Journal of Sexual MedicineCitation Excerpt :The overall grade of recommendation is grade A. Further, there is clear evidence that vardenafil is efficacious in a number of special populations of men where the ED has arisen secondary to a specific disease such as diabetes [117–119], men with ED secondary to radical retropubic prostatectomy [120], depression [121], hypertension [122], spinal cord injury and ED [123], hyperlipidemia [124] and men who have previously failed to respond to sildenafil [125]. Although side effects do occur with vardenafil (most notably headache, flushing, indigestion and nasal congestion), providing that the drug is used in line with the labeling recommendations, there is no convincing evidence in the literature of any significant safety issue, including cardiovascular, visual and aural safety [105–127]. If any sudden loss of vision occurs, the individual should stop taking the medication and seek medical help immediately. Vision problems are most likely in patients with other conditions, such as heart or coronary artery disease, diabetes, and high cholesterol. Vision problems are more likely to happen if the person smokes, or if they are aged over 50 years. Using vardenafil with some other drugs can lead to serious adverse effects. a potentially dangerous drop in blood pressure, or hypotension There is also a risk of stroke and heart attack. A man should not use vardenafil if he is taking nitrate drugs, such as riociguat (Adempas), or other nitrate drugs for chest pain or heart problems.

It should not be used with the recreational drugs, amyl nitrate and butyl nitrate, also known as poppers. Other drugs that may interact include, but are not limited to: drugs for prostate problems, blood pressure, or heart rhythm disorders Grapefruit juice contains a chemical that makes adverse effects more likely, so it should not be consumed while using vardenafil.

Patients should tell their doctor about all their medical conditions and any other medications or supplements they use before taking vardenafil.
