[Interpretation of reactions to acetylsalicylic acid and glaphenine].

Challenge test puts in evidence the responsibility of a drug. The biological checking by plasmatic histamine leads to distinguish between a specific histamine-release reaction and a non-specific one. Thus, glafenine has proved to be a non specific histamine release where as in some cases, acetyl-salicylic-acid (A.S.A.) behaves like a specific histamine release.
