US Eli Lilly Cialis 20mg: Core Ingredients and Mechanism of Action
US Eli Lilly Cialis 20mg 30 tablets is a prescription medication for male erectile dysfunction (ED, referring to the inability to achieve or maintain an erection sufficient for sexual intercourse). Its active ingredient is Tadalafil, which belongs to the class of PDE5 inhibitors (phosphodiesterase type 5 inhibitors). By blocking PDE5 enzyme activity, it promotes relaxation of the smooth muscles in the penile corpus cavernosum, dilates blood vessels, and increases local blood flow, thereby helping to achieve and maintain an erection. This medication requires sexual stimulation to take effect and is intended for on-demand use.
