AVAILABLE MEDICINE FOR Avanafil

Avanafil is a commonly used prescription medication that helps to treat erectile dysfunction (ED). Discovered at Tanabe Seiyaku (now Mitsubishi Tanabe), the molecule falls under the class of medications known as PDE5 or Phosphodiesterase inhibitors. 

Avanafil inhibits the PDE5 enzyme, which increases blood flow to the penis during sexual stimulation. It is generally known by its brand name Stendra that sells Avanafil tablets in various strengths. 

Basic Information 

Avanafil molecule helps increase blood circulation to the penis at the time of sexual stimulation. Here is a list of the key information you must keep in mind:

1. Chemical Structure and Formula: It comes with a unique chemical structure C23H26ClN7O3. It consists of pyrimidine carboxyamide, chloromethoxy benxylamino group and a pyrimidinylmethyl group.

2. Discovered In: The molecule was originally discovered at Tanabe Seiyaku (now Mitsubishi Tanabe). Choongwae Pharma now JW Pharmaceutical and VIVUS developed and launched it to treat erectile dysfunction (ED).

3. FDA Approval: The Food and Drug Administration (FDA) approved it for the treatment of ED on April 27, 2012, and the European Medicines Agency (EMA) approved it on June 21, 2013.

4. Mode of Action: This molecule works by preventing the formation of an enzyme (called PDE5) in the body, which enables the relaxation of specific blood vessels. Avanafil boosts the blood flow to the penis during sexual stimulation, making it easier to arouse and keep an erection.

Uses of Avanafil

Avanafil is primarily used to treat erectile dysfunction (ED). However, it is not a cure for ED, nor does it enhance sexual desire. It also does not prevent sexually transmitted infections (STIs) or affect fertility.

Erectile Dysfunction (ED) is a condition where a man has difficulty achieving or maintaining an erection during sexual arousal. According to records, this issue is quite common. If you experience any of the following symptoms, consult a healthcare professional for guidance:

• Flaccid penis 

• Less sexual desire

• Trouble keeping an erection

By effectively addressing symptoms of erectile dysfunction and premature ejaculation, this medication can significantly enhance your sexual well-being, fostering a more fulfilling and intimate relationship with your partner.

How It Works?

Avanafil enhances blood flow to the penis, playing a crucial role in treating erectile dysfunction (ED).

During sexual arousal, the body naturally increases blood flow to the penis to facilitate an erection. However, an enzyme called phosphodiesterase type-5 (PDE5) can interfere with this process, making it difficult to achieve or maintain an erection.

Avanafil works by inhibiting PDE5, allowing for improved blood circulation in the penis when a man is sexually stimulated. While the medication aids in sustaining an erection, it does not induce one on its own. Physical stimulation, such as sexual arousal, is still necessary for it to take effect.
