What is Vardenafil? (Levitra, Staxyn: The Essentials)
Vardenafil is a powerful oral medication classified as a PDE5 inhibitor (phosphodiesterase type 5 inhibitor) and is best known under the brand names Levitra and Staxyn. Designed specifically to treat erectile dysfunction (ED), Vardenafil works by increasing blood flow to the penis, enabling firm, long-lasting erections in response to sexual stimulation.
- Drug Class: Phosphodiesterase Type 5 Inhibitor
- Brand Names: Levitra, Staxyn
- First Approved: FDA, 2003 (FDA Approved Drugs Database)
- Prescription Required: Yes
How Does Vardenafil Work? Mechanism of Action Explained
Inside the body, Vardenafil targets the PDE5 enzyme, which is responsible for regulating blood flow in the penis. By inhibiting PDE5, Vardenafil boosts levels of cyclic guanosine monophosphate (cGMP), a molecule that relaxes blood vessels and enhances blood flow. The outcome? A natural, reliable erection in response to sexual arousal—without affecting libido or producing an erection in the absence of stimulation.
- Sexual stimulation triggers nitric oxide release in the penis.
- Nitric oxide increases cGMP production.
- cGMP relaxes smooth muscle and dilates blood vessels.
- PDE5 typically breaks down cGMP, ending erections.
- Vardenafil blocks PDE5, sustaining cGMP and erection duration.
When is Vardenafil Prescribed? Indications & Who Needs It
While Vardenafil is most famous for treating erectile dysfunction, it may also be considered for other conditions under off-label use, such as premature ejaculation (limited evidence, consult your doctor). Doctors recommend it especially for patients who:
- Do not respond adequately to sildenafil (Viagra) or tadalafil (Cialis)
- Need a medication with a rapid onset and predictable window of action
- Have chronic medical conditions such as diabetes or hypertension making other ED medications less suitable (NIH review)
How to Use Vardenafil: Dosage, Timing, and Pro Tips
| Preparation | Standard Dosage | Onset of Action | Duration |
|---|---|---|---|
| Tablets (Levitra) | 10mg before intercourse | 30-60 min | Up to 5 hours |
| Orodispersible (Staxyn) | 10mg before intercourse | 30-60 min | Up to 5 hours |
Typical starting dose for most adults is 10mg, adjusted by your doctor as needed (5mg to 20mg).
- Take only once per day—never exceed 20mg in 24 hours.
- For best results, take on an empty stomach (high-fat meals may delay effects).
- Avoid grapefruit or grapefruit juice, which can amplify side effects (Mayo Clinic).
- Sexual stimulation is required for the drug to work.
Doctor’s Note on Dosage
“Vardenafil dosing should always be individualized in consultation with your healthcare provider. Some men respond well to just 5mg, while others need 20mg for a satisfactory effect. The goal is maximal efficacy with minimal side effects.” — Dr. Laura M., Board-certified Urologist
