Dexamethasone-induced neutrophilia. Negative correlation with increased plasma adrenaline concentrations

Maximal increments in adrenaline and dexamethasone (DXM) plasma concentrations were observed c15 (T50 40 min) and 30 (T50 210-240 min) minutes after an i.v. DXM dose (6 mg/m2 BSA) in man. There appears, however, to be no direct interaction between these agents in the development of induced neutrophilia, which occurs c240 min postinjection.
