Viagra 100mg 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 a condition in which a man has difficulty achieving or maintaining an erection sufficient for satisfactory sexual activity.
Viagra works by increasing blood flow to the penis during sexual stimulation, helping to produce and maintain an erection. It does not increase sexual desire, cure erectile dysfunction, or provide protection against sexually transmitted infections (STIs). Sexual stimulation is necessary for the medication to work effectively.
The 100mg strength is generally prescribed for individuals who require a higher dose based on their healthcare provider's assessment of treatment response, overall health, and tolerance to the medication.

Viagra belongs to the PDE5 inhibitor class of medications. It works by inhibiting the phosphodiesterase type 5 enzyme, allowing increased levels of cyclic guanosine monophosphate (cGMP). This process relaxes smooth muscle tissue and enhances blood flow to the penis during sexual stimulation.
Its mechanism of action may help:
Improve erectile function
Increase blood flow to the penis
Support firmer and longer-lasting erections
Enhance sexual performance in men with erectile dysfunction
Improve confidence during intimate activity
Viagra is effective only when sexual stimulation occurs and does not cause spontaneous erections.
