Cromoglycate and nedocromil enhanced the reactive oxygen species‐dependent suppressions with, but not without, dexamethasone in ischaemic and histamine paw oedema of mice

Mediators of Inflammation, Volume 6, Issue 5-6, Page 369-374, 1997., 1997
Anti‐inflammatory actions of two anti‐allergic drugs, alone or with dexamethasone (Dex) were examined in two models, because inflammation is claimed to be important for allergic events, especially for asthma. Cromoglycate and nedocromil were tested in ischaemic‐ and histamineinduced paw oedema models of mice. These antiallergic drugs (1–100 mg/kg, i.p.)
