This will increase the supply of blood to the lungs and reduce the workload of the heart.

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 25 mg for sale cambios en su visión o pérdida súbita de la visión; o
