About Zudena
Zudena is a brand-name oral tablet that contains the active ingredient udenafil, a phosphodiesterase-5 (PDE-5) inhibitor. Although not listed on the Health Sciences Authority’s (HSA) approved medicines in Singapore, it is marketed internationally for the treatment of erectile dysfunction (ED). The 100 mg pill works by enhancing blood flow to the penile tissue during sexual stimulation, allowing men to achieve and maintain an erection sufficient for intercourse. Off-label interest has emerged for conditions such as pulmonary arterial hypertension, but such uses remain investigational and should only be pursued under specialist supervision.
What is Zudena?
Zudena belongs to the PDE-5 inhibitor class, the same therapeutic group that includes sildenafil and tadalafil. It was first introduced in markets where regulatory pathways allow the sale of non-approved erectile-function agents. In Singapore, the product is available only through import channels and is not recognized by the HSA for prescription or over-the-counter sale. The 100 mg tablet delivers a standardized dose of udenafil, which is chemically distinct from sildenafil yet shares a similar mechanism of action. While brand equivalents are limited, the formulation is marketed as a convenient once-daily option for men seeking a reliable solution to ED.
How Zudena Works
Udenafil inhibits the enzyme phosphodiesterase-5, an enzyme that degrades cyclic guanosine monophosphate (cG-MP) in the smooth muscle of the corpus cavernosum. By blocking PDE-5, Zudena allows cG-MP to accumulate, promoting relaxation of the smooth muscle and dilation of the penile arteries. This physiological cascade increases blood inflow, producing an erection when sexual arousal triggers nitric oxide release. Pharmacokinetic studies indicate an onset of action within 30-60 minutes, with a half-life of roughly 12 hours, providing a longer therapeutic window than some older agents. The drug is primarily metabolised by hepatic CYP3A4 enzymes and excreted in the urine, necessitating caution when combined with strong CYP3A4 inhibitors.
Why Zudena is Used for Sexual Health Conditions
- Erectile Dysfunction - By sustaining elevated cG-MP levels, Zudena directly addresses the vascular component of ED, restoring the physiological response required for an erection. Clinical trials in Asia have reported response rates comparable to sildenafil, with a favorable safety profile.
- First-Line Option - International guidelines for ED list PDE-5 inhibitors as the preferred initial pharmacotherapy. Zudena’s 100 mg dose offers a balance between efficacy and tolerability for men who have not responded adequately to lower doses of other agents.
- Longer Duration - The extended half-life supports a more flexible sexual window, which some patients find advantageous over agents requiring precise timing.
- Alternative for Tolerability Issues - Patients experiencing headaches or flushing with sildenafil may tolerate udenafil better, as side-effect patterns differ slightly across the class.
Off-Label and Investigational Uses of Zudena
Evidence from small-scale studies suggests that udenafil may improve exercise capacity in patients with pulmonary arterial hypertension by reducing pulmonary vascular resistance. However, the HSA has not approved Zudena for this indication, and robust phase-III data are lacking. Off-label use should only be considered under the supervision of a qualified healthcare provider.
Is Zudena Right for You?
Ideal candidates are adult men with a clinical diagnosis of erectile dysfunction who have not achieved satisfactory results with lifestyle modifications alone. Men with stable cardiovascular disease may use Zudena safely, provided they are not taking nitrates or potent α-blockers. Caution is advised for individuals with severe hepatic or renal impairment, as drug clearance may be reduced. Pregnant or breastfeeding individuals are excluded, as animal studies have not established safety. Ultimately, personal medical history and concurrent medications determine suitability; a physician’s assessment remains essential.
Taking Zudena Effectively
- Timing - Ingest the tablet with a glass of water 30-60 minutes before anticipated sexual activity. Food does not markedly affect absorption, though a high-fat meal may delay onset by up to 15 minutes.
- Missed Dose - If a dose is forgotten and the planned activity occurs within four hours, take it immediately; otherwise, skip and resume the regular schedule. Do not double-dose.
- Travel - Keep the medication in its original container, away from extreme temperatures. For long flights, consider a portable pill case to avoid breakage.
- Interaction Management - Avoid concurrent use of nitrates (e.g., nitroglycerin) or recreational “poppers,” as the combination can precipitate severe hypotension.

Frequently Asked Questions
-
Can Zudena be taken daily? Yes, some men use a 100 mg tablet once each day to maintain a ready-to-go therapeutic level, but daily dosing should be discussed with a clinician to assess safety.
-
Will Zudena interact with alcohol? Moderate alcohol consumption does not usually affect efficacy, but excessive intake can amplify dizziness or low blood pressure.
-
How does Zudena compare with sildenafil? Both inhibit PDE-5, yet udenafil’s longer half-life provides a broader window for sexual activity; individual response varies, so trial under medical guidance may be required.
-
Is a prescription needed in Singapore? While HSA does not list Zudena as an approved medication, a prescription from a licensed physician is recommended to ensure safe use and proper monitoring.
-
What should I do if I experience a prolonged erection? Seek immediate medical attention if an erection persists longer than four hours, as this may signal priapism, a medical emergency.
-
Can women use Zudena? Zudena is formulated for male physiology and has not been studied for female sexual dysfunction; it is not recommended for women.
-
Will food affect absorption? A high-fat meal might delay onset slightly, but overall bioavailability remains largely unchanged.
-
Is it safe with antihypertensive medication? Generally, yes, but concurrent use with nitrates is contraindicated due to the risk of severe hypotension.
-
How long does the effect last? Most users report sustained erectile capability for up to 12 hours after ingestion, depending on individual metabolism.
-
What is the recommended storage condition? Store at room temperature, away from direct sunlight and moisture; avoid freezing temperatures.
