The list of drugs incriminated at one time or another in the etiology of each dyscrasia was as long as the pharmacopoeia itself. Based on the clinical evidence, however, there were patterns for each dyscrasia, some of which overlapped. Drugs commonly linked to aplastic anemia included chloramphenicol, phenylbutazone, oxyphenbutazone, sulfonamides, and antithyroid drugs; all of them, except chloramphenicol, were also implicated in the etiology of agranulocytosis, together with phenothiazine derivatives. The same drugs were commonly linked to thrombocytopenia, which had also frequently been linked to the use of quinidine. The exact listing of drugs related to each disorder varied between reports and, presumably, between patterns of drug use in different populations. One major concern in 1985 was with all of the newer nonsteroidal anti-inflammatory drugs currently on the market in the United States. There were numerous case reports implicating these drugs in the etiology of all three dyscrasias.
