Vilitra 40 mg is a high-dose erectile dysfunction (ED) medication containing vardenafil, a PDE5 inhibitor that enhances blood flow to the penis during sexual arousal. It is designed for men who may not respond adequately to lower doses such as 10 mg or 20 mg. In the context of precision health—an approach to medical treatment that considers individual variability—Vilitra 40 mg represents a more tailored option for managing ED in specific patient populations.
