Zudena is a Sunrise Remedies udenafil brand. Its current company catalogue lists 100 and 200 mg tablets. It is a separate product identity from Dong-A’s original Zydena, despite the similar spelling.
Do not transfer the company record
The Sunrise listing supports the brand–ingredient–company association. Dong-A’s international market table concerns Zydena and does not establish Zudena’s authorization in those markets. Likewise, a trial using the original brand is ingredient evidence, not a product-specific study of every Sunrise presentation.
The company range is useful for identifying a pack, while a matching local leaflet and supply record are needed to establish the actual prescribing context. Absence from the retail databases checked here would not, on its own, prove that a product is export-only or unavailable in India.
What udenafil research contributes
Udenafil has an intermediate exposure pattern relative to familiar shorter-acting sildenafil and longer-acting tadalafil. Healthy-volunteer peak and half-life estimates describe blood levels rather than the duration of successful intercourse. A selected trial in men receiving antihypertensive treatment showed benefit against placebo, but does not settle suitability for every blood-pressure medicine or cardiac condition.
The udenafil page presents those studies with their populations and limits. It is a better starting point than a promise that a 200 mg pack lasts twice as long as 100 mg. The exact formulation, cardiovascular review and other medicines still matter when comparing brands.

Listed strengths identify a product; they are not dosing advice. A listing in one country does not show that a product is authorized where you live.
About udenafil
Udenafil was developed in South Korea; Dong-A ST also lists exports to several countries. Its research half-life describes blood exposure, not guaranteed sexual duration. Company-reported presence does not replace a current local product record.
About Indian brands
Indian-company brands have different retail and catalogue evidence. A pharmacy database entry does not establish current stock, and absence from a checked database does not prove export-only manufacture. Company association, exact product identity and local authorization are separate questions.
Using a PDE5 inhibitor safely
Never take a PDE5 inhibitor with nitrates, recreational nitrites (“poppers”) or riociguat, and do not combine two ED medicines. Seek urgent medical help for chest pain, an erection lasting more than four hours, or sudden loss of vision or hearing.
Common side effects include headache, flushing, indigestion and a blocked nose.
