What Is Viagra 25mg?

Viagra 25mg contains the active ingredient sildenafil citrate, a prescription phosphodiesterase type 5 (PDE5) inhibitor used to treat erectile dysfunction (ED) in adult men. Erectile dysfunction is the inability to achieve or maintain an erection firm enough for satisfactory sexual activity.

Viagra works by increasing blood flow to the penis during sexual stimulation, helping men achieve and maintain an erection naturally. It does not increase sexual desire, cure erectile dysfunction, or protect against sexually transmitted infections (STIs). Sexual stimulation is required for the medication to be effective.

The 25mg strength is often prescribed as a lower starting dose for individuals who may be more sensitive to sildenafil, including some older adults or those with certain medical conditions or medication interactions.

How Viagra 25mg Works

Viagra belongs to the PDE5 inhibitor class of medications. It works by blocking the phosphodiesterase type 5 enzyme, which increases the levels of cyclic guanosine monophosphate (cGMP). This relaxes smooth muscles and improves blood flow to the penis during sexual stimulation.

Its effects may help:

• Improve erectile function

• Increase blood flow to the penis

• Help achieve and maintain an erection

• Enhance sexual performance in men with erectile dysfunction

• Support confidence during sexual activity

Viagra only works when sexual stimulation is present and does not cause automatic erections.
