Udenafil tablets, commonly known by brand names like Zudena, are phosphodiesterase-5 (PDE5) inhibitors used to treat erectile dysfunction (ED) by improving blood flow to the penis, acting relatively quickly and lasting for a significant duration. Available in strengths like 100mg and 200mg, they can be taken on-demand or once daily.

Key Characteristics:

• Mechanism: Blocks PDE5 enzyme, relaxing muscles and increasing blood flow.

• Onset & Duration: Fast-acting (around 1 hour) with a long half-life (11-13 hours), offering both rapid and sustained effects.

• Usage: Effective for both on-demand and daily dosing for ED. 

Common Uses:

• Erectile Dysfunction (ED): Primary use for treating impotence in adult men.

• Combination Products: Some tablets (e.g., Super Zudena) combine Udenafil with Dapoxetine for premature ejaculation (PE).
