Vilitra (Vardenafil 10 mg, 20 mg, 40 mg, 60 mg): Comprehensive Patient Information for Canada

Basic Product Information

Mechanism of Action

In simple terms: Vardenafil is a medication used to treat erectile dysfunction (ED). It works by increasing blood flow to the penis during sexual stimulation. When you become sexually aroused, your body releases a natural chemical called nitric oxide, which triggers a series of events that relax the blood vessels in the penis and allow more blood to flow in, creating an erection. Vardenafil helps this process by blocking an enzyme called PDE5 that normally breaks down the chemical responsible for keeping those blood vessels relaxed. Vardenafil will only help you get an erection if you are sexually stimulated.

For specialists: Vardenafil is a selective inhibitor of cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase type 5 (PDE5), the predominant PDE in the human corpus cavernosum. During sexual stimulation, nitric oxide is released from nerve endings and endothelial cells, activating guanylate cyclase and increasing cGMP synthesis. cGMP triggers smooth muscle relaxation, allowing increased blood flow into the penis and resulting in erection. Vardenafil inhibits PDE5, thereby increasing cGMP levels and enhancing erectile function. Because sexual stimulation is required to initiate the local release of nitric oxide, PDE5 inhibition has no effect in the absence of sexual stimulation. In vitro studies have shown that vardenafil is more selective for PDE5 than for other known phosphodiesterases, with greater than 15-fold selectivity relative to PDE6, greater than 130-fold relative to PDE1, greater than 300-fold relative to PDE11, and greater than 1,000-fold relative to PDE2, 3, 4, 7, 8, 9, and 10.

Pharmacokinetics

• Absorption: Vardenafil is rapidly absorbed after oral administration, with peak plasma concentrations reached in approximately 30 to 120 minutes (median approximately 60 minutes) in the fasting state. The absolute bioavailability is approximately 15%. The pharmacokinetics are approximately dose proportional over the recommended dose range. A high-fat meal reduces peak plasma concentration and delays time to peak concentration.
• Metabolism: Vardenafil is eliminated predominantly by hepatic metabolism, mainly by CYP3A4 and to a minor extent by CYP3A5 and CYP2C isoforms. The primary circulating metabolite (M1) is formed by CYP3A4 and has approximately 28% of the PDE5 inhibitory activity of vardenafil.
• Elimination: The total body clearance of vardenafil is 56 L/h. The terminal half-life of vardenafil and its primary metabolite (M1) is approximately 4 to 5 hours. Approximately 91 to 95% of vardenafil and M1 are bound to plasma proteins.
• Onset of Action: Vardenafil typically takes effect within 25 to 60 minutes after administration. Some patients may respond as early as 15 to 30 minutes.
• Duration of Action: The duration of action is approximately 4 to 6 hours.

Uses in Daily Life and Best Practice Advice

Vardenafil is prescribed in Canada for the treatment of erectile dysfunction. Your physician will determine the appropriate dose and use based on your specific medical situation.

• Typical Uses: Treatment of erectile dysfunction in adult men. Vardenafil has also been studied in the management of ureteral stent-related symptoms, showing promising results in controlling these symptoms and potentially serving as an alternative or adjunct medication to tamsulosin.
• Administration: Take vardenafil orally approximately 25 to 60 minutes before sexual activity. The maximum recommended dosing frequency is once per day. Vardenafil may be taken with or without food, but a high-fat meal may reduce its effectiveness.
• Monitoring: No routine laboratory monitoring is required. Your physician will assess your response to treatment and adjust the dose if necessary.
• Do Not Use Without Sexual Stimulation: Vardenafil will only help you get an erection if you are sexually stimulated. It does not cause spontaneous erections and does not affect libido.

Morning vs. Evening Dosing

Vardenafil is taken as needed, approximately 25 to 60 minutes before sexual activity. There is no specific recommendation for morning versus evening dosing. Choose a time that is convenient for you and allows sufficient time for the medication to take effect. Always follow the guidance of your physician.

• As-Needed Use: Vardenafil is not taken on a fixed daily schedule. It is taken when sexual activity is anticipated.
• Consistency: The maximum recommended dosing frequency is once per day. Do not take more than one dose in a 24-hour period.
• Missed Dose: Vardenafil is taken as needed, so missed-dose schedules do not apply. Take it only when you plan to have sexual activity.
• Professional Guidance: Your healthcare provider may adjust the timing based on your response and any other medications you are taking.

Administration With or Without Food

Vardenafil may be taken with or without food. However, a high-fat meal can reduce the peak plasma concentration and delay the time to peak concentration, which may reduce the effectiveness of the medication. For best results, avoid taking vardenafil after a heavy, high-fat meal.

• Take vardenafil with a full glass of water.
• Avoid high-fat meals before taking vardenafil, as they may reduce its effectiveness.
• Do not crush, chew, or split the tablet unless directed by your physician or pharmacist. For orally disintegrating tablets, follow the specific instructions provided with the product.
• Avoid drinking grapefruit juice during treatment, as it may increase vardenafil levels in the blood and cause unpredictable side effects.

Doses should always be adjusted according to the advice of your physician and depending on your health condition. Do not exceed the maximum recommended dose of 20 mg once daily.

Side Effects and Safety Profile

Guidelines for Correct Use

• Take vardenafil exactly as prescribed by your physician. Do not change your dose without medical advice.
• Take the tablet approximately 25 to 60 minutes before sexual activity. The maximum recommended dosing frequency is once per day.
• Swallow the tablet whole with water. For orally disintegrating tablets, follow the specific instructions provided with the product.
• Do not take vardenafil more than once per day.
• Do not use vardenafil if you are taking nitrates or guanylate cyclase stimulators.
• Avoid drinking grapefruit juice during treatment.
• Avoid excessive alcohol consumption.
• Inform every healthcare provider (including dentists, surgeons, and pharmacists) that you are taking vardenafil.
• Seek immediate medical attention if you experience an erection lasting more than 4 hours, sudden vision loss, or sudden hearing loss.
• If you are pregnant, planning to become pregnant, or breastfeeding, vardenafil is not indicated for use in women. Consult your physician for alternative options.
• Keep out of reach of children. Store at room temperature in a dry place.

Alternative Treatment Options

• Sildenafil (Viagra, generic): Another PDE5 inhibitor taken as needed. Onset of action is approximately 30 to 60 minutes. Duration of action is approximately 4 hours. Available in generic form in Canada and widely covered.
• Tadalafil (Cialis, generic): A longer-acting PDE5 inhibitor available in both as-needed and once-daily dosing. Duration of action is up to 36 hours. Available in generic form in Canada.
• Avanafil (Stendra): A newer PDE5 inhibitor with a faster onset of action (as early as 15 minutes). Available by prescription in Canada.
• Alprostadil: Available as an injectable or intraurethral suppository for men who do not respond to oral PDE5 inhibitors. Requires medical supervision.
• Testosterone Replacement Therapy: For men with documented hypogonadism, testosterone replacement may improve erectile function, particularly when combined with a PDE5 inhibitor.
• Vacuum Erection Devices and Penile Implants: Mechanical and surgical options for men who cannot take or do not respond to oral medications.

Comparison: Vardenafil is similar in efficacy to sildenafil and tadalafil. It has a slightly faster onset than sildenafil in some patients and is available as an orally disintegrating tablet, which may be convenient for some users. However, vardenafil is generally not covered by provincial drug plans for erectile dysfunction, and generic vardenafil may be more difficult to find and more expensive than generic sildenafil or tadalafil. Your physician will determine the best option for your specific needs and health status.
