What is Vardenafil? Mode of action and pharmacological properties

Vardenafil belongs to a class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors. Its primary action is to restore the ability to achieve and maintain an erection sufficient for satisfactory sexual intercourse. Vardenafil works by increasing blood flow to the penis during sexual stimulation.

Mechanism of action of Vardenafil:

PDE5 Inhibition Vardenafil inhibits the PDE5 enzyme, which is responsible for the breakdown of cyclic guanosine monophosphate (cGMP) in the corpus cavernosum of the penis.
Increased cGMP levels: Blocking PDE5 leads to a build-up of cGMP.
Smooth Muscle Relaxation: Elevated cGMP levels cause the smooth muscles of the penile arteries to relax.
Relaxed arteries provide increased blood flow to the penis during sexual arousal, helping to achieve an erection.

It is important to remember that Vardenafil does not automatically cause an erection. It is only effective when there is sexual stimulation. Without sexual arousal, the drug will not work.

Indications for use: When can Vardenafil be useful?

Vardenafil is the mainstay of treatment for:

Erectile dysfunction (ED): The main indication for the use of Vardenafil. ED is a condition in which a man cannot achieve or maintain an erection sufficient for full sexual intercourse. Vardenafil helps improve blood flow to the penis, providing a reliable erection in response to sexual arousal.

Vardenafil is intended solely for the treatment of erectile dysfunction. It is not indicated for use in women or children. If you think Vardenafil may be helpful, you should consult your doctor for diagnosis and individual treatment recommendations.

How to take Vardenafil correctly

Proper use and dosage of Vardenafil are key factors to achieve optimal results and minimize the risk of side effects. Always follow your doctor’s recommendations and the instructions that come with the drug.

Dosage recommendations for erectile dysfunction:

Initial Dose The generally recommended initial dose is 10 mg taken orally approximately 25 to 60 minutes before sexual activity.
Dose adjustment: Depending on the effectiveness and tolerability, the dose may be increased to 20 mg or decreased to 5 mg. Dosage adjustments should only be made on the advice of a physician.
Maximum Dose: The maximum recommended dose of Vardenafil is 20 mg/day. Do not take more than one dose per day.
Frequency of administration Vardenafil should be taken only when needed, approximately 25-60 minutes before planned sexual activity. The effect may take up to 4-5 hours.

Contraindications: in what cases Vardenafil should not be used

There are certain medical conditions and situations where Vardenafil is contraindicated. It is important to be aware of these contraindications to avoid potential health risks.

The main contraindications for the use of Vardenafil:

Concomitant use of nitrates: Vardenafil is absolutely contraindicated in combination with any form of nitrates, including nitroglycerin, isosorbide dinitrate and isosorbide mononitrate used to treat angina. The combination of these drugs can cause a sharp and dangerous decrease in blood pressure.
Hypersensitivity to Vardenafil or any component of the drug: If there is a known allergy to Vardenafil or excipients in the drug, its use is contraindicated.
Severe cardiovascular disease: Patients with severe cardiac disease such as unstable angina, severe heart failure, uncontrolled arrhythmias, or recent myocardial infarction or stroke should avoid using Vardenafil.
Severe liver impairment: In severe liver impairment, the metabolism of Vardenafil may be significantly impaired, which may lead to increased blood levels of the drug and an increased risk of side effects.
Severe renal impairment requiring dialysis: In severe renal impairment, especially in patients requiring dialysis, the elimination of Vardenafil from the body may be delayed, which also increases the risk of side effects.
Hereditary retinal degenerative diseases: Patients with retinitis pigmentosa or other hereditary retinal diseases should avoid using Vardenafil due to the risk of visual impairment.
Loss of vision in one eye due to non-arteritic anterior ischemic optic neuropathy (NAINO): If vision loss was associated with the use of PDE5 inhibitors, the use of Vardenafil is contraindicated.
Concomitant use with strong CYP3A4 inhibitors: Concomitant use of Vardenafil with strong CYP3A4 inhibitors such as ketoconazole or itraconazole (orally administered), ritonavir, indinavir is contraindicated.

Before you start taking Vardenafil, be sure to tell your doctor about all your medical conditions and any medications you are taking.

Warnings and precautions: what to consider before starting treatment

Before starting treatment with Vardenafil, it is important to be aware of certain precautions and warnings that will help ensure the safety and effectiveness of the therapy.

Important precautions and precautions:

Cardiovascular risks: Sexual activity puts extra strain on the heart, especially for people with heart disease. Before prescribing Vardenafil, your doctor should evaluate your cardiovascular health and determine whether sexual activity is safe for you.
Priapism: In rare cases, Vardenafil may cause priapism, a prolonged and painful erection lasting more than 4 hours. If you experience an erection that lasts longer than 4 hours, seek immediate medical attention, as priapism can cause damage to the penile tissue and permanent loss of potency.
Vision problems: In rare cases, vision problems such as non-arteritic anterior ischemic optic neuropathy (NAINO) have been reported in patients taking PDE5 inhibitors, including Vardenafil. If you experience sudden worsening or loss of vision, stop taking Vardenafil immediately and contact your doctor.
Hearing problems: In rare cases, sudden decrease or loss of hearing has been reported in patients taking Vardenafil. If sudden hearing loss occurs, stop taking the drug and contact your doctor.
Interactions with other medicines Vardenafil may interact with many other medicines, including alpha blockers, certain antifungals, antibiotics, and HIV medicines. Tell your doctor all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.
Effects on ability to drive and use machines Vardenafil may cause dizziness and visual impairment in some patients. Therefore, before driving or operating machinery, make sure you know how the drug affects your reaction.
Alcohol consumption: Drinking alcohol while taking Vardenafil may increase the risk of side effects such as dizziness and decreased blood pressure. It is recommended to limit alcohol consumption while taking Vardenafil.
Penile deformity: Vardenafil should be used with caution in patients with anatomical deformity of the penis (e.g. angulation, cavernosal fibrosis or Peyronie’s disease).

Discuss all your medical conditions, allergies, and medications with your doctor before starting Vardenafil to ensure its safe and effective use.

Side effects: possible adverse reactions and when to call a doctor

Like any medication, vardenafil can cause side effects. Although most are mild and temporary, it is important to be aware of potential side effects and know when to seek medical attention.

The most common side effects of Vardenafil are:

Headache: One of the most common side effects, related to the dilation of blood vessels in the head.
Facial flushing (hot flashes) Also associated with vasodilation, resulting in a feeling of warmth and redness of the skin of the face, neck and chest.
Nasal congestion Vardenafil may cause swelling of the nasal mucosa, leading to nasal congestion.
Upset stomach (dyspepsia): May include heartburn, nausea, abdominal pain, or diarrhea.
Dizziness: May be caused by decreased blood pressure.
Visual disturbances: May include temporary decreased vision, blurred vision, increased sensitivity to light, or changes in color perception (slight bluish tint to vision).

Less common but more serious side effects that require medical attention include:

Priapism (prolonged erection): An erection lasting more than 4 hours is a medical emergency and requires immediate treatment.
Sudden loss or worsening of vision: May be a sign of NVD.
Sudden decrease or loss of hearing: May be a sign of damage to the auditory nerve.
Allergic reactions: Although rare, allergic reactions such as rash, itching, swelling of the face, lips, tongue or throat, difficulty breathing are possible. If an allergic reaction occurs, seek immediate medical attention.

When to see a doctor:

If any serious side effects occur, such as priapism, vision or hearing problems, allergic reactions.
If side effects become severe or do not go away for a long time.
If you experience any unusual or worrying symptoms that you think may be related to taking Vardenafil.

Interaction with other drugs: what combinations should be avoided

Vardenafil interactions with other medications may be significant and may affect treatment efficacy and safety. It is important to be aware of potential interactions and be sure to tell your doctor about all medications you are taking.

Medicines that should be avoided when used concomitantly with Vardenafil:

Nitrates: As already mentioned, the concomitant use of Vardenafil with nitrates (eg nitroglycerin, isosorbide dinitrate, isosorbide mononitrate) is absolutely contraindicated due to the risk of dangerous decrease in blood pressure.
Strong CYP3A4 inhibitors: Concomitant use of Vardenafil with strong CYP3A4 inhibitors such as ketoconazole or itraconazole (for oral use), ritonavir, indinavir is contraindicated as this may significantly increase the concentration of Vardenafil in the blood and increase.
Other PDE5 inhibitors: It is not recommended to take Vardenafil at the same time as other erectile dysfunction medications such as sildenafil, tadalafil or avanafil, as this may increase the risk of side effects.

Medicines that require caution and dose adjustment when combined with:

Alpha blockers: When used concomitantly with alpha blockers (drugs used to treat hypertension or prostate hyperplasia), Vardenafil may cause symptomatic hypotension (dizziness, loss of consciousness). In such cases, the initial dose of Vardenafil may be reduced.
Moderate CYP3A4 inhibitors: When used concomitantly with moderate CYP3A4 inhibitors such as erythromycin or clarithromycin, the concentration of Vardenafil in the blood may increase, which may increase the risk of side effects. In such cases, a reduction in the dose of Vardenafil may be required.
CYP3A4 inducers: Some drugs such as rifampicin, phenytoin, carbamazepine and other CYP3A4 inducers may decrease the blood concentration of Vardenafil, which may reduce its effectiveness. In such cases, an increase in the Vardenafil dose may be required.
Antihypertensive drugs Vardenafil may enhance the hypotensive effect of antihypertensive drugs. Although this is not usually a contraindication, caution should be exercised and blood pressure should be monitored, especially at the beginning of treatment.

Always tell your doctor about all the medications you are taking to avoid unwanted interactions and ensure safe and effective treatment.
