Tadalista 40 is a medication used to treat erectile dysfunction (ED) in men. It contains tadalafil as its active ingredient, which is a phosphodiesterase type 5 (PDE5) inhibitor. Tadalafil works by increasing blood flow to the penile during physical stimulation, helping men achieve and maintain an erection. It is typically taken orally with a glass of water, with or without food. It is usually recommended to be taken about 30 minutes before anticipated physical activity. https://www.genericday.com/tadalista-40-mg.html
