Mechanism of Action
For patients: Levitra contains vardenafil, which helps men with erectile dysfunction (ED) achieve and maintain an erection that is suitable for sexual activity. It works by increasing blood flow to the penis when sexual arousal occurs.
For specialists: Vardenafil is a selective phosphodiesterase type 5 (PDE5) inhibitor. Inhibition of PDE5 enhances the effect of nitric oxide (NO) by increasing cGMP levels in corpus cavernosum smooth muscle, resulting in smooth muscle relaxation and increased penile blood flow.
Pharmacokinetics
- Absorption: Rapidly absorbed orally; peak plasma concentrations reached ~30-120 minutes after dosing (median Tmax ~60 minutes).
- Bioavailability: Approx. 15% due to first-pass metabolism.
- Metabolism: Primarily hepatic via CYP3A4 (main pathway), with minor involvement from CYP3A5 and CYP2C isoenzymes.
- Elimination: Mainly as metabolites via faeces (91–95%); < 2% renal excretion.
- Duration of action: Effective up to 4–5 hours post-dose; some effect may last up to 8 hours.
- Half-life: About 4–5 hours.
Use in Everyday Life and Best Practices
- Typical Dose: For most men, the recommended starting dose is 10 mg taken about 25–60 minutes before sexual activity.
- How to Take: Swallow the tablet whole with a glass of water. Only take one dose per day.
- Maximum Frequency: Once per day, regardless of sexual activity frequency.
- Australian Context: Australians are advised to have the medicine on hand before anticipated activity, respecting privacy and individual routine.
Dosing in the Morning vs Evening
- Morning Use: Suitable for men with anticipated morning intimacy. Food intake may affect absorption minimally.
- Evening Use (More Common): Optimal for planned evening sexual activity, following dinner or relaxation period.
- Regularity Tips: Take Levitra at a consistent time relative to activity. Do not split or double up doses if one is missed.
Taking with Food or on an Empty Stomach
Levitra may be taken with or without food. However, if taken with a heavy or high-fat meal—a common part of some Australian diets (e.g., steak dinners, rich seafood)—the onset of action may be delayed but not reduced in effect. For best results, consider taking Levitra on an empty stomach or after a light meal.
Interaction Warnings
| Interaction | Recommendation |
|---|---|
| Alcohol | Moderation advised; excess alcohol can reduce effectiveness and increase side effects (e.g., dizziness). |
| Grapefruit Juice | Avoid; inhibits metabolism (CYP3A4), raising vardenafil levels and risk of adverse events. |
| Nitrate Medications (e.g., GTN for angina) | Contraindicated; may cause severe hypotension. |
| Alpha-blockers (for blood pressure/prostate) | May cause low blood pressure; medical advice required before co-administration. |
| Other PDE5 inhibitors (sildenafil, tadalafil) | Do not combine with other ED medications. |
| Strong CYP3A4 Inhibitors (e.g., ketoconazole, ritonavir) | May raise vardenafil levels; not recommended unless supervised by a specialist. |

Guidelines for Proper Use
- Use only as prescribed by your doctor or prescriber.
- Discuss long-term use with your healthcare provider for regular monitoring.
- Avoid recreational use or combining with illicit substances.
- Store tablets in a cool, dry place below 25°C, away from direct sunlight.
- Keep out of sight and reach of children.
- Return unused or expired medicine to your pharmacy as per local regulations.
Alternative Treatment Options
- Sildenafil (Viagra, generic): Widely used, cost-effective, slightly longer duration (4–6h), may be affected by fatty meals.
- Tadalafil (Cialis): Longer action (up to 36h, "weekend pill"), daily/once-daily options, not affected by food.
- Avanafil (not PBS-reimbursed): Rapid onset, newer but less widely available.
- Penile injections (alprostadil): Effective for severe ED, but invasive.
- Vacuum erection devices: Useful for medication intolerance; non-pharmacological option.
Comparison: Choice depends on personal preference, duration of action required, side-effect tolerance, and presence of other illnesses. Levitra may be preferred where rapid, reliable action is important and where side-effect profile is better tolerated.
Legal, Registration, and Reimbursement Status in Australia
- TGA (Therapeutic Goods Administration) registration: Yes, fully registered for erectile dysfunction.
- Prescription status: Schedule 4 (S4), prescription required from a registered healthcare provider.
- PBS (Pharmaceutical Benefits Scheme) reimbursement: Not routinely PBS-listed for ED—most patients pay private prescription prices.

Latest Research & Clinical Guidance (2022–2025)
- 2022–2025 ENDO/ISSWSH/Australian Sexual Health Society: PDE5 inhibitors (including vardenafil) remain first-line pharmacotherapy for ED (J Sex Med, 2023; MJA Practice Essentials: Sexual Health, 2024).
- Meta-analyses (Cui et al., 2023; Anderson et al., 2024): Vardenafil is effective for a broad range of ED aetiologies. No significant new cardiovascular, ocular, or hearing safety signals observed with standard use.
- For diabetic and elderly patients: Vardenafil may offer slightly improved efficacy but similar safety profile to other PDE5 inhibitors.
- Combination therapies: Not recommended outside specialist advice.
