Sildenafil for ED: How It Works

Due to age or other factors, some men may experience erectile dysfunction. The treatment options available for this vary, and at Boston Vitality we offer multiple treatments. One of our options is Sildenafil, a prescription medication. Sildenafil is a type of medication known as a PDE-5 inhibitor, which is the main ingredient in the drug Viagra.

What is Erectile Dysfunction?

Erectile dysfunction, or impotence, is a condition that makes it hard for a man to get or keep an erection. Although there are various causes, the most common is a narrowing of the arteries responsible for blood flow to the penis. Men who are impotent have trouble getting and keeping an erection that is firm enough for sex. They may also experience a decline in sexual desire.

The following are some conditions that may cause erectile dysfunction:

• Heart disease, high blood pressure, or clogged blood vessels
• High blood pressure or high cholesterol
• Diabetes or obesity
• Tobacco use or alcoholism
• Scar tissue inside the penis
• Sleep disorders like apnea
• Treatments for enlarged prostate or prostate cancer

How Does Sildenafil Work?

Sildenafil works by stopping the action of PDE-5, an enzyme that regulates the relaxation and contraction of smooth muscles. The drug helps to open the blood vessels so blood can flow to the penis after it is sexually stimulated, making an erection last longer.

How Long Does it Take for Sildenafil to Work?

Effects of the drug vary from person to person. It starts to work for most men within 20 minutes after it is taken. It will not, however, produce an erection without sexual stimulation. Although Sildenafil has little effect in the absence of impotence, studies suggest it can delay ejaculation in some users who do not have ED. A dose of the medication usually lasts several hours.
