Zydena’s active ingredient is udenafil, a phosphodiesterase-5 (PDE5) inhibitor. Udenafil works by increasing blood flow to the penis, facilitating erection. This happens by blocking the action of PDE5, an enzyme that breaks down cyclic guanosine monophosphate (cGMP), a crucial molecule for achieving and maintaining an erection.
Cialis, on the other hand, utilizes tadalafil, another PDE5 inhibitor. Tadalafil’s mechanism is similar to udenafil’s; it inhibits PDE5, leading to increased cGMP levels and improved blood flow to the penis. The key difference lies in their duration of action.
- Udenafil (Zydena): Offers a shorter duration of effect compared to tadalafil. Tadalafil (Cialis): Provides a significantly longer duration, often referred to as “the weekend pill” due to its extended effectiveness.
Both medications share the same basic mechanism, but their differing chemical structures result in variations in their onset, duration, and potential side effects. Consult your physician to determine which medication best suits your individual needs and health profile. They can provide personalized advice, considering your medical history and other medications you are taking.
Consider onset time: Udenafil may act faster for some individuals. Consider duration needed: Tadalafil offers longer-lasting effects. Discuss potential side effects: Both medications have potential side effects, which your doctor can explain.
