Zudena 100 Mg is a phosphodiesterase type 5 (PDE5) inhibitor, a class of drugs commonly used to treat ED. The active ingredient, Udenafil, works by increasing blood flow to the penis, helping men achieve and maintain an erection sufficient for sexual intercourse. This medication is typically taken on an as-needed basis, with effects lasting up to 12 hours, making it a reliable option for many men. The primary benefit of Zudena 100 Mg is its ability to enhance sexual performance, leading to improved confidence and satisfaction in relationships. However, as with any medication, understanding its broader effects, including those on sleep, is essential for overall well-being.
