Vidalista 40 mg contains tadalafil as its active ingredient, which is a phosphodiesterase type 5 (PDE5) inhibitor used to treat erectile dysfunction (ED) in men. Tadalafil works by increasing blood flow to the penis during sexual stimulation, facilitating the ability to achieve and maintain an erection. Regarding its effect on libido (sexual desire or arousal), similar to Vidalista 20 mg, Vidalista 40 mg primarily targets the physical aspects of erectile function rather than directly affecting libido. While tadalafil does not directly influence libido, resolving issues related to ED can indirectly impact sexual desire and arousal. https://www.onemedz.com/product/vidalista-40-mg/
