Vardenafil: Everything You Need to Know in 2024

What is Vardenafil? | Erectile Dysfunction Solution

Vardenafil is an FDA-approved oral medication used to treat erectile dysfunction (ED) in men. Part of the class known as phosphodiesterase type 5 (PDE5) inhibitors, it is best recognized by brand names such as Levitra® and Staxyn®. Since its introduction, Vardenafil has offered millions of men a safe and effective solution for achieving and maintaining erections.

Quick Facts About Vardenafil:

• Category: PDE5 inhibitor
• Indication: Erectile dysfunction
• Onset: 30-60 minutes
• Duration: Up to 8 hours
• Availability: Tablet, orally disintegrating tablet (ODT)

Mechanism of Action: How Does Vardenafil Work?

Vardenafil works by enhancing blood flow to the penis during sexual stimulation. It inhibits the PDE5 enzyme, which is responsible for breaking down cyclic guanosine monophosphate (cGMP). Increased levels of cGMP relax the smooth muscles and widen blood vessels in the penis, resulting in improved erections (see figure below).

Step	Description
1	Sexual arousal causes release of nitric oxide (NO)
2	NO stimulates cGMP production
3	PDE5 inhibitors like Vardenafil prevent cGMP breakdown
4	Smooth muscle relaxation & increased blood flow
5	Firm, long-lasting erection possible

Clinical Indications: Who Can Use Vardenafil?

Vardenafil is primarily prescribed for adult men experiencing erectile dysfunction, regardless of the underlying cause (psychogenic, organic, mixed). Common indications include:

• Performance anxiety
• Age-related ED
• Vascular or neurogenic impotence
• Diabetes-related ED

Not suitable for: Women, children, or men allergic to any of its components.

Why Choose Vardenafil Over Other ED Medications?

Key differences vs. Sildenafil (Viagra®) and Tadalafil (Cialis®):
