Itch interacts with the other sensory modalities at multiple locations, from its initiation in a particular dermatome to its transmission to the brain where it is finally perceived. In this review, we summarize the current understanding of the molecular and neural mechanisms of itch by starting in the periphery, where itch is initiated, and discussing the circuits involved in itch processing in the CNS. Optic neuropathy due to plaquenil How can plaquenil affect your eyes Chloroquine diphosphate and phosphate The itch-scratch reflex serves as a protective mechanism in everyday life. However, chronic persistent itching can be devastating. Despite the clinical importance of the itch sensation, its mechanism remains elusive. In the past decade, substantial progress has been made to uncover the mystery of itching. Here, we review the molecules, cells, and circuits known to mediate the itch sensation. Interestingly, scratching in response to the classical itch-promoting substances histamine and chloroquine did not differ between the young and aged mice, suggesting that the pathways underlying chemical itch are unaffected by aging. Chloroquine Phosphate. Chloroquine is used to prevent or treat malaria caused by mosquito bites in countries where malaria is common. Malaria parasites can enter the body through these mosquito bites, and then live in body tissues such as red blood cells or the liver. Although not all of these side effects may occur, if they do occur they may need medical attention. Applies to chloroquine: oral tablet Along with its needed effects, chloroquine may cause some unwanted effects.

Since the focus of this review is the neuronal mechanism of itch, we will restrict our discussion on molecular mediators with well-established neuronal receptors that directly activate itch neurons or enhance their activation. Molecules that cause itch indirectly for example, through activating mast cells will not be included here. The itch-scratch reflex serves as a protective mechanism in everyday life. However, chronic persistent itching can be devastating. Despite the clinical importance of the itch sensation, its mechanism remains elusive. In the past decade, substantial progress has been made to uncover the mystery of itching. Chloroquine-induced itching is very common among black Africans 70%, but much less common in other races. It increases with age, and is so severe as to stop compliance with drug therapy. It is increased during malaria fever; its severity is correlated to the malaria parasite load in blood.
