The active ingredient in Zudena 100 mg tablet , a drug intended to treat erectile dysfunction (ED) in men, is 100 mg of udenafil. By blocking the PDE5 enzyme, udenafil helps men get and maintain an erection by boosting blood flow to the penis during sexual stimulation. With effects that last 12 to 24 hours, Zudena is renowned for having a longer half-life than other ED drugs, giving users greater freedom in when to have sex.

This medicine should only be used under a doctor's supervision and is normally given 30 to 60 minutes prior to sexual activity. Despite its effectiveness, Zudena should not be taken with alcohol or drugs that contain nitrates since these chemicals can interact dangerously. Headaches, lightheadedness, or moderate dyspepsia are common side effects that typically go away with time. To guarantee its safety and efficacy for your particular medical needs, always take the recommended dosage as directed by a physician.
