By increasing the stiffness of erythrocytes infected by the causal agent of malaria, Viagra favors their elimination from the blood circulation and may therefore reduce transmission of the parasite from humans to mosquitoes. This astonishing discovery, made by scientists from the CNRS, INSERM, Université Paris Descartes -- at the Institut Cochin -- and the Institut Pasteur, working in collaboration with a team from the London School of Hygiene and Tropical Medicine, could lead to a treatment to reduce the spread of malaria within a population. Their work is published in PLOS Pathogens on 7 May 2015.No se sabe si sildenafil pasa a la leche materna o si le puede hacer da?o al bebé lactante.

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]

Cialis is an effective, reversible, selective inhibitor of phosphodiesterase type 5 (PDE 5) specific to cyclic guanosine monophosphate (cGMP). When sexual stimulation causes local release of nitric oxide, inhibition of PDE 5 by Cialis leads to increase of cGMP levels in the cavernous body of penis. It results in relaxation of arterial smooth muscles and blood flow to the tissues of the penis that causes erections. Cialis has no effect when sexual stimulation is absent. Cialis improves erection and lets achieve a successful sexual intercourse. The drug acts during 36 hours. If sexual arousal is present the effect appears even after 16 minutes after the medication was taken.
