Apcalis SX contains Tadalafil, a phosphodiesterase-5 (PDE5) inhibitor. This means it works by relaxing blood vessels in the penis, allowing for increased blood flow necessary for an erection. This mechanism differs from other medications, making Tadalafil a unique treatment option.
How Tadalafil Works
Tadalafil’s impact on PDE5 leads to increased levels of cGMP, a chemical that facilitates smooth muscle relaxation. This improved blood flow is triggered by sexual stimulation. Importantly, Tadalafil doesn’t cause erections without stimulation; it simply enhances the body’s natural response.
Tadalafil’s Duration of Action
A key advantage of Tadalafil is its longer duration of action compared to some other PDE5 inhibitors. The effects can last up to 36 hours, allowing for greater flexibility and spontaneity.
