Tadalafil, sildenafil, and vardenafil all act by inhibiting the PDE5 enzyme. These drugs also inhibit other PDE enzymes. Sildenafil and vardenafil inhibit PDE6, an enzyme found in the eye, more than tadalafil.[7] Some sildenafil users see a bluish tinge and have a heightened sensitivity to light because of PDE6 inhibition.[8] Sildenafil and vardenafil also inhibit PDE1 more than tadalafil.[7] PDE1 is found in the brain, heart, and vascular smooth muscle.[7] It is thought that the inhibition of PDE1 by sildenafil and vardenafil leads to vasodilation, flushing, and tachycardia.[7] Tadalafil inhibits PDE11 more than sildenafil or vardenafil.[7] PDE11 is expressed in skeletal muscle, the prostate, the liver, the kidney, the pituitary gland, and the testes.[7] The effects on the body of inhibiting PDE11 are not known.[7] viagra directions ?itching or burning during urination
