1. Effects and Mechanism of Action (效果与作用机制)

English: Cialis 20mg belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. It works by relaxing blood vessels in the penis, allowing increased blood flow during sexual stimulation. This helps achieve and maintain an erection. Unlike some shorter-acting ED medications, Cialis remains effective for up to 36 hours, offering a longer window of opportunity.
