What is Viagra?

Viagra, a well-known name in the realm of pharmaceuticals, is synonymous with effective treatment for erectile dysfunction (ED). Originally manufactured by Pfizer, its active ingredient, sildenafil citrate, was initially intended to treat hypertension and angina but soon became famous for its ability to enhance erectile function. Viagra works by increasing blood flow to the penis, helping men achieve and maintain an erection suitable for sexual activity.

How Does Viagra Work?

To understand Viagra’s mechanism of action, it’s essential to delve into the science behind it. Viagra belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. It works by blocking the PDE5 enzyme, which results in the relaxation of blood vessels in the penis. This relaxation allows increased blood flow when a man is sexually aroused, leading to an erection.

Indications for Viagra Use

Viagra is primarily prescribed for treating erectile dysfunction. Whether ED stems from physiological or psychological factors, Viagra has proven effective for many men. The drug’s ability to assist those struggling with erectile function has made it a staple in ED treatment. However, it’s crucial to consult a healthcare provider to determine if Viagra is right for you.

### Common Uses and Dosage

– Standard Dosage: The typical starting dose is 50 mg taken approximately one hour before sexual activity. Depending on efficacy and tolerance, the dose can be adjusted to 25 mg or 100 mg.
– Administration: Viagra should be taken orally with water. It’s important to note that it won’t work without sexual stimulation.

Possible Side Effects of Viagra

While Viagra is generally safe, like all medications, it comes with potential side effects. These can include headaches, flushing, indigestion, or nasal congestion. Rare but serious side effects include vision or hearing changes, and prolonged erections longer than four hours, known as priapism, which requires immediate medical attention.
