  Aplastic anemia - Wikipedia, the free encyclopedia
Aplastic anemia is a condition where the bone marrow does not produce enough, or any, new cells to replenish the blood cells.
Anemia is the condition of having fewer blood cells than normal, or fewer than needed to function properly.
In many cases, the etiology is impossible to determine, but aplastic anemia is sometimes associated with exposure to substances such as benzene,radiation, or to the use of certain drugs, including chloramphenicol and phenylbutazone.

 Aplastic Anemia Information on Healthline
Aplastic anemia is a disorder in which the bone marrow greatly decreases or stops production of blood cells.
In aplastic anemia, the basic structure of the marrow becomes abnormal, and those cells responsible for generating blood cells (hematopoietic cells) are greatly decreased in number or absent.
Symptoms of aplastic anemia tend to be those of other anemias, including fatigue, weakness, tiny reddish-purple marks (petechiae) on the skin (evidence of pinpoint hemorrhages into the skin), evidence of abnormal bruising, and bleeding from the gums, nose, intestine, or vagina.

 Aplastic anaemia
Aplastic anaemia is a rare acquired disorder in which there is a failure of the bone marrow to produce sufficient blood cells for the circulation.
The difference from acquired aplastic anaemia is that the fall in blood cells occurs acutely over one or two days and recovery takes place in the majority of patients if they are supported through the period of marrow depression with blood transfusions.
The risk of developing aplastic anaemia as a side-effect of drug treatment is very small, for the antibiotic chloramphenicol, one of the more widely studied triggers for the disease, about one person in 25,000 taking the drug may develop aplastic anaemia.
