What is Viagra (Sildenafil 100 mg)?
Viagra is a prescription medication containing Sildenafil citrate, primarily used to treat erectile dysfunction (ED) in adult men. ED is the inability to achieve or maintain an erection sufficient for satisfactory sexual activity. Sildenafil belongs to a class of medicines known as phosphodiesterase type 5 (PDE5) inhibitors. (medicines.org.uk
)
When a man becomes sexually aroused, nitric oxide is released in the penis, activating an enzyme that increases cyclic guanosine monophosphate (cGMP). cGMP relaxes the smooth muscles in the penile blood vessels, allowing blood to fill the erectile tissue. Sildenafil works by blocking PDE5, an enzyme that breaks down cGMP, thereby prolonging the effects of sexual stimulation and improving the ability to maintain an erection.
Importantly, Viagra does not induce an erection automatically. Sexual stimulation is still necessary for the drug to be effective. The 100 mg dose is considered the highest recommended dose for adults, typically prescribed when lower doses (25 mg or 50 mg) are insufficient. (medicines.org.uk

Uses of Viagra 100 mg
1. Treatment of Erectile Dysfunction
Viagra 100 mg is prescribed for men with moderate to severe ED who have not responded adequately to lower doses. ED can result from a variety of causes, including:
-
Vascular issues (poor blood flow to the penis)
-
Diabetes or other metabolic disorders
-
Hormonal imbalances
-
Psychological causes (stress, anxiety, depression)
-
Medication side effects
By improving blood flow to the penis, Viagra enables men to achieve and maintain an erection sufficient for sexual intercourse. (medicines.org.uk

2. Pulmonary Arterial Hypertension (Off-Label / Related Uses)
While the 100 mg dose is specifically for ED, Sildenafil in other formulations is sometimes used to treat pulmonary arterial hypertension by relaxing blood vessels in the lungs. However, the Viagra tablet is not primarily prescribed for this purpose.
