Buy Viagra 100 mg (Sildenafil) – Product Information (EU Medical Overview)

Product Main Description

Viagra 100 mg is a prescription-only medicine containing the active ingredient sildenafil citrate. It belongs to a class of medicines called phosphodiesterase type 5 (PDE5) inhibitors.

It is used in adult men for the treatment of erectile dysfunction (ED), a condition where achieving or maintaining an erection sufficient for sexual activity is difficult. Sildenafil works only in the presence of sexual stimulation and is not an aphrodisiac or hormone treatment.

In European clinical practice, sildenafil 100 mg is typically used when lower doses are not sufficiently effective and only under medical supervision.

Therapeutic Use and Clinical Context

Viagra 100 mg is prescribed for:

• Erectile dysfunction of various causes (vascular, psychological, or mixed)
• Cases where lower sildenafil doses (25 mg or 50 mg) are not effective
• Improving erectile response in men with reduced penile blood flow

It is not indicated for use in women, children, or adolescents.

Mechanism of Action

Sildenafil works by inhibiting the PDE5 enzyme, which regulates blood flow in the penis. By blocking this enzyme, sildenafil enhances the effects of nitric oxide and increases levels of cyclic guanosine monophosphate (cGMP), leading to:

• Relaxation of smooth muscle in penile blood vessels
• Increased blood flow to erectile tissue
• Improved ability to achieve and maintain an erection during sexual stimulation

It only works when sexual stimulation is present; it does not cause automatic erection.
