Tadalista 10 is a medication used to treat erectile dysfunction (ED), and it contains tadalafil as its active ingredient. Tadalafil is a phosphodiesterase type 5 (PDE5) inhibitor, similar to sildenafil and vardenafil. It works by increasing blood flow to the penis, facilitating the ability to achieve and maintain an erection when a man is sexually aroused. The effects of Tadalista 10 typically last for about 36 hours. It is usually taken about 30 minutes to an hour before anticipated sexual activity.
