Avanafil is a modern and fast-acting drug, specially designed to treat erectile dysfunction (ED) in men. This extended instruction manual will provide you with comprehensive information about Avanafil, from its mechanism of action and indications to the correct dosage, potential side effects and important precautions. Our goal is to provide you with complete knowledge so that you can use Avanafil effectively and safely, achieving the desired results in improving your sex life and overall well-being.

What is Avanafil? Mechanism of Action and Pharmacology

Avanafil belongs to a class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors. Its main action is to promote relaxation of the smooth muscles of the blood vessels in the penis, allowing for increased blood flow to the penis during sexual stimulation. This process helps men achieve and maintain an erection sufficient for full intercourse.

Mechanism of action of Avanafil:

  1. Selective PDE5 inhibition: Avanafil specifically blocks the PDE5 enzyme, which is responsible for breaking down cyclic guanosine monophosphate (cGMP) in the corpus cavernosum of the penis.
  2. Increased cGMP levels: Inhibition of PDE5 results in increased cGMP concentrations in the corpus cavernosum.
  3. Smooth Muscle Relaxation: Elevated cGMP levels cause relaxation of the smooth muscles in the arteries of the penis.
  4. Increased Blood Flow to the Penis: Relaxed arteries allow more blood to flow into the penis during sexual stimulation, which initiates an erection.

It is important to understand that Avanafil does not cause an erection spontaneously. It requires sexual stimulation to be effective. Without sexual arousal, the drug will not work. It is this selective action on PDE5 in the penis that makes Avanafil relatively fast-acting and reduces the risk of certain side effects compared to less selective PDE inhibitors.

Indications for use: in what cases can Avanafil help?

Avanafil is primarily intended for the treatment of:

  • Erectile dysfunction (ED): This is the primary indication for Avanafil. ED is the persistent inability to achieve or maintain an erection sufficient for satisfactory sexual intercourse. Avanafil helps improve blood flow to the penis, helping to achieve and maintain an erection in response to sexual arousal. Avanafil’s rapid action makes it particularly suitable for use immediately before planned sexual activity.

Avanafil is a drug for the treatment of erectile dysfunction in men only. It is not intended for use in women or children. If you suspect erectile dysfunction and are considering Avanafil as a treatment option, you should consult with your doctor to establish a diagnosis and determine if the drug is right for you.

Directions for use and dosage: how to take Avanafil correctly

Proper use and dosage of Avanafil are critical to achieving maximum effectiveness and minimizing the risk of unwanted effects. Always follow your doctor’s recommendations and the instructions on the package.

Dosage recommendations for erectile dysfunction:

  • The recommended starting dose is usually 100 mg taken orally approximately 15-30 minutes before sexual activity. Avanafil is one of the fastest acting drugs among the PDE5 inhibitors.
  • Dose adjustment: Depending on individual response and tolerability, the dose may be increased to 200 mg or decreased to 50 mg. Dosage adjustments should only be made on the advice of a physician. Some men may find 50 mg sufficient to achieve satisfactory results, while others may require 200 mg for optimal response.
  • Maximum Dose: The maximum recommended dose of Avanafil is 200 mg/day. Do not take more than one dose of Avanafil within 24 hours.
  • Frequency of administration: Avanafil should be taken only when needed before planned sexual activity. Due to its rapid action, the drug allows for greater spontaneity in sexual relations. The effect of Avanafil can take up to 4-5 hours.
  • Avanafil can be taken regardless of food intake . However, it should be remembered that a large fatty meal may slightly slow down the onset of action of the drug. For the fastest possible effect, it is recommended to take Avanafil on an empty stomach or after a light meal.

General recommendations:

  • Take Avanafil only as directed by your doctor.
  • Do not change the dosage on your own without consulting your doctor.
  • Do not take the medicine more often than recommended.
  • If you have any questions about how to use the drug, consult your doctor or pharmacist.

Contraindications: When Avanafil Should Not Be Used

There are certain conditions and situations when Avanafil is contraindicated. It is important to be aware of these contraindications to prevent possible negative health consequences.

The main contraindications for the use of Avanafil:

  • Concomitant use of nitrates: Concomitant use of Avanafil with any form of nitrates (eg, nitroglycerin, isosorbide dinitrate, isosorbide mononitrate) is absolutely contraindicated. This combination can cause a sharp and dangerous decrease in blood pressure, which can be fatal.
  • Hypersensitivity to Avanafil or any of the excipients of the drug: If you have a known allergy to Avanafil or any other ingredient of the drug, its use is prohibited.
  • 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 Avanafil. Sexual activity puts additional strain on the heart and the use of ED drugs may be risky for these patients.
  • Severe hepatic impairment: In severe hepatic impairment, Avanafil metabolism may be significantly impaired, which may lead to increased blood levels of the drug and an increased risk of adverse effects.
  • Severe renal failure (end-stage renal disease) or need for dialysis: In severe renal failure, the elimination of Avanafil from the body may be slower, which also increases the risk of side effects.
  • Hereditary retinal degenerative diseases: Patients with retinitis pigmentosa or other hereditary retinal diseases should avoid using Avanafil due to the potential risk of visual impairment.
  • Recent stroke or myocardial infarction If a stroke or myocardial infarction has occurred within the last 6 months, the use of Avanafil is contraindicated.
  • Arterial hypotension (low blood pressure): Avanafil may lower blood pressure, so it is not recommended for use in patients with hypotension.
  • Concomitant use with strong CYP3A4 inhibitors: Concomitant use of Avanafil with strong CYP3A4 inhibitors such as ketoconazole, itraconazole, ritonavir, indinavir is contraindicated as this may significantly increase Avanafil blood concentrations and increase the risk.

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

Warnings and Precautions: What is Important to Know Before Starting Treatment

Before starting treatment with Avanafil, it is important to know certain precautions and precautions that will help minimize risks and ensure safe use of the drug.
