Mechanism & Pharmacology

Udenafil is a phosphodiesterase type 5 (PDE5) inhibitor that facilitates penile erection by enhancing blood flow. Mechanistically, it works by preventing the breakdown of cyclic guanosine monophosphate (cGMP), a molecule that plays a crucial role in the relaxation of the blood vessels in the penis. When sexual stimulation occurs, the body produces nitric oxide, leading to increased levels of cGMP. By inhibiting PDE5, udenafil ensures that cGMP levels remain elevated, thereby allowing for sustained vasodilation and improved erectile function during sexual activity.

Simplified explanation (patient-friendly)

When a man is sexually stimulated, the body releases a chemical that helps increase blood flow to the penis. Udenafil helps keep that blood flowing by blocking a specific enzyme that usually breaks down a messenger called cGMP. The more cGMP present, the more relaxation of blood vessels occurs, making it easier to achieve and maintain an erection.

Clinical terms

According to Health Canada approved monographs, the mechanism of udenafil aligns well with clinical recommendations for treating erectile dysfunction. By inhibiting PDE5, udenafil addresses barriers to adequate blood flow, serving as a practical option in treatment regimens aimed at restoring sexual function. Its efficacy has drawn comparisons with other PDE5 inhibitors, underscoring its role in contemporary therapeutic guidelines.

Indications & Off-Label Uses in Canada

Udenafil is not approved for use in Canada. While it shows promise internationally, specifically approved uses remain absent within the Canadian framework. This leads to varying expectations regarding its application among healthcare providers.

Approved indications

In Canada, udenafil has no approved indications. Internationally, particularly in South Korea where it is marketed as Zydena, it is mainly indicated for erectile dysfunction. The lack of Health Canada approval limits its availability and recognition in local health care practices.

Common off-label practices

Canadian physicians have occasionally turned to udenafil off-label, sharing anecdotal experiences that indicate a positive reception among patients who have not found success with other treatments. While evidence supporting its effectiveness in off-label uses is largely anecdotal, some practitioners have described it as a valuable alternative under specific circumstances.
