Tadalafil, the active ingredient in
Tadalista 20, is a PDE5 inhibitor. It works by relaxing the blood vessels in the penis, allowing more blood to flow in and resulting in an erection when sexually stimulated. Tadalista 20 does not cause spontaneous erections and requires sexual arousal to work effectively. If you experience sudden loss of vision or hearing, stop using the medication and seek medical help immediately. Chest pain, irregular heartbeat, or signs of a heart attack should be addressed by a healthcare professional immediately.
