Vidalista 40 mg contains tadalafil, a medication used to treat erectile dysfunction (ED) in men. Tadalafil is a phosphodiesterase type 5 (PDE5) inhibitor, which works by increasing blood flow to the penis during sexual stimulation, helping men achieve and maintain erections. The 40 mg strength of Vidalista is a mid-range dose, with higher doses available (such as Vidalista 60 mg) for those who may require a stronger effect or have not responded adequately to lower doses. https://www.onemedz.com/product/vidalista-40-mg/
