Tadaflo belongs to a class of medications called phosphodiesterase type 5 (PDE5) inhibitors. Its primary mechanism of action involves inhibiting the enzyme PDE5, which is responsible for breaking down cyclic guanosine monophosphate (cGMP). By inhibiting PDE5, Tadaflo prolongs the effects of cGMP, leading to smooth muscle relaxation, vasodilation, and increased blood flow to the penis, thereby facilitating erections. This mechanism also plays a role in relieving symptoms of BPH by relaxing the smooth muscles of the prostate and bladder neck.
