Vardenafil is a phosphodiesterase type 5 (PDE5) inhibitor used primarily to treat erectile dysfunction (ED). Classified alongside sildenafil and tadalafil, it enhances the nitric-oxide-cGMP pathway in penile tissue, facilitating smooth-muscle relaxation and increased blood flow during sexual stimulation. First approved by the U.S. Food and Drug Administration (FDA) in 2003, the medication later received endorsement from the European Medicines Agency (EMA) and the Australian Therapeutic Goods Administration (TGA). Branded as Levitra and available in generic form, vardenafil is prescribed to adult men who experience difficulty achieving or maintaining an erection. Off-label, it has been investigated for pulmonary arterial hypertension, though such use remains investigational in Australia. The drug’s rapid onset-typically within 30 minutes-and a duration of effect lasting up to 5 hours make it a convenient option for many patients seeking reliable, short-term management of ED.

What is Vardenafil?

Vardenafil belongs to the PDE5 inhibitor class, a group of agents that selectively block the phosphodiesterase-5 enzyme responsible for degrading cyclic guanosine monophosphate (cGMP) in the corpus cavernosum. The TGA lists its initial registration in 2004 for erectile dysfunction, with subsequent updates confirming its safety profile for adult males. By inhibiting PDE5, vardenafil preserves cGMP levels, allowing nitric oxide released during sexual arousal to maintain smooth-muscle relaxation and engorgement of penile tissue. The drug is marketed globally under the brand name Levitra and is also distributed as a generic tablet. Both branded and generic versions can be ordered through our online pharmacy, offering a discreet and convenient way to obtain the medication.

How Vardenafil Works

Mechanism of Action

Vardenafil binds competitively to the active site of the PDE5 enzyme, preventing the hydrolysis of cGMP into inactive GMP. Elevated cGMP concentrations keep the intracellular calcium channels closed, which sustains smooth-muscle relaxation in the penile arteries and corpus cavernosum.

Therapeutic Effects

The physiological result is enhanced arterial inflow and restricted venous outflow, producing a firmer erection when sexual stimulation triggers nitric-oxide release. Because the drug’s effect is activity-dependent, it does not cause an erection without sexual arousal.

Onset and Duration

Clinical trials cited by the FDA show that ≥ 60 % of men report an erection within 30 minutes of taking a 10 mg tablet. Peak plasma concentrations occur at 60 minutes, and the therapeutic window extends up to 5 hours, allowing flexibility for spontaneous sexual activity.

Approved Uses and Applications

Approved Indications

Erectile Dysfunction - The sole indication approved by the TGA, FDA, and EMA for adult men. Studies published in The New England Journal of Medicine demonstrated a 70 % improvement in International Index of Erectile Function (IIEF) scores compared with placebo.

Off-Label Uses

Pulmonary Arterial Hypertension (PAH) - Small Phase II trials have explored vardenafil’s vasodilatory effect on pulmonary vessels, but the TGA has not approved it for this condition.

Clinical Efficacy

In a randomized, double-blind trial involving 602 participants, vardenafil 10 mg produced a 68 % increase in successful intercourse attempts versus 24 % with placebo (p < .001). Similar efficacy has been reported in sub-analyses of men with diabetes and post-prostatectomy patients, confirming its broad applicability across diverse ED etiologies.

Dosing, Formulations & Administration

Available Formulations

Vardenafil is supplied as oral tablets in 5 mg, 10 mg, and 20 mg strengths.

Typical Dosing Ranges

For erectile dysfunction, clinicians often start with a 10 mg tablet taken about 30 minutes before sexual activity. Depending on efficacy and tolerability, the dose may be adjusted to 5 mg or increased to a maximum of 20 mg.

Administration Guidelines

Take the tablet with a glass of water; food-particularly high-fat meals-can delay absorption, so a fasted state may provide quicker onset. Do not exceed one dose per 24-hour period. The exact dose should be determined by a healthcare professional based on individual health status and concomitant medications.

Safety Profile & Considerations

Common Side Effects

Headache (≈ 15 % of users)
Flushing (≈ 12 %)
Nasal congestion (≈ 10 %)
Dyspepsia (≈ 9 %)

These events are typically mild and transient.

Serious Adverse Events

Priapism - An erection lasting > 4 hours requires immediate medical attention.
Sudden loss of vision - May indicate non-arteritic anterior ischemic optic neuropathy (NAION); urgent evaluation is essential.

Contraindications

Concurrent use of nitrates (e.g., nitroglycerin)
Severe hypotension (systolic < 90 mmHg)
Known hypersensitivity to vardenafil or any tablet components

Drug Interactions

CYP3A4 inhibitors (ketoconazole, erythromycin) can increase vardenafil plasma levels.
Other PDE5 inhibitors - Co-administration heightens cardiovascular risk.
Alpha-blockers - May potentiate blood-pressure lowering effects.

Special Populations

Pregnancy & Breastfeeding - Not indicated; safety data are lacking.
Elderly - Dose adjustments may be needed due to age-related renal or hepatic decline.
Renal/Hepatic Impairment - Moderate impairment warrants a reduced starting dose (5 mg).

Frequently Asked Questions

How does Vardenafil differ from Sildenafil? Vardenafil has a slightly faster onset (≈ 30 minutes) and a shorter half-life, which can result in a narrower therapeutic window compared with sildenafil’s 4-6 hour duration.
How long before Vardenafil produces noticeable effects for erectile dysfunction? Most men experience an erection within 30 minutes after ingestion, though peak efficacy is reached around 60 minutes.
Can I take Vardenafil with a high-fat meal? Fatty meals may delay absorption and reduce the speed of onset; a light meal or fasting state is recommended for optimal effect.
What should I do if I experience a persistent headache after taking Vardenafil? Over-the-counter analgesics such as acetaminophen are generally safe, but you should discuss recurring headaches with your clinician.
Is it safe to use Vardenafil if I have mild hypertension? Vardenafil can modestly lower blood pressure; patients with well-controlled hypertension may use it, but a doctor should evaluate cardiovascular risk first.
Can Vardenafil cause vision changes? Rarely, users report blurred vision or color perception changes; any sudden visual loss warrants immediate medical evaluation.
Does alcohol affect Vardenafil’s effectiveness? Moderate alcohol consumption may diminish erectile response; excessive intake can increase the risk of hypotension and side effects.
What foods should I avoid while taking Vardenafil? Grapefruit juice can inhibit CYP3A4 metabolism, potentially raising plasma levels and side-effect risk.
How does Vardenafil interact with other medications for heart disease? Alpha-blockers and certain anti-arrhythmic agents can amplify blood-pressure-lowering effects; a thorough medication review by a healthcare provider is essential.
What information should I provide my doctor when discussing Vardenafil?
- Complete medical history, including cardiovascular conditions.
- Full list of current prescriptions, over-the-counter drugs, and supplements.
- Any prior experience with PDE5 inhibitors and associated side effects.
- Specific goals and concerns regarding sexual health.
