Effects of sodium cromoglycate and nedocromil sodium on histamine secretion from human lung mast cells.
Sodium cromoglycate and nedocromil sodium produced a dose dependent inhibition of histamine secretion from human pulmonary mast cells obtained by bronchoalveolar lavage and by enzymatic dissociation of lung parenchyma. Both compounds were significantly more active against the lavage cells than against the dispersed lung cells, and nedocromil sodium was an order of magnitude more effective than ...
متن کاملEffect of nedocromil sodium and sodium cromoglycate against bronchoconstriction induced by inhaled adenosine 5'-monophosphate.
In this randomized, double-blind, placebo controlled study, the effect of prior inhalation of nebulized sodium cromoglycate (SCG) (7.3 +/- 0.6 mg) and nedocromil sodium (NED) (7.5 +/- 0.6 mg) was observed on adenosine 5'-monophosphate (AMP)-induced bronchoconstriction in 11 non-atopic asthmatic subjects. The geometric mean provocation doses of methacholine and AMP required to produce a 20% decr...
متن کاملAttenuation of exercise induced asthma by nedocromil sodium and sodium cromoglycate.
A randomized double blind cross over trial to compare nedocromil sodium and sodium cromoglycate with placebo in the prevention of exercise induced asthma was conducted. Twenty asthmatics received nedocromil sodium, sodium cromoglycate or placebo via metered dose inhalers on successive days 30 minutes before exercise in a randomized order. Nedocromil sodium and sodium cromoglycate gave sufficien...
متن کاملEffect of inhaled beclomethasone and nedocromil sodium on bronchial hyperresponsiveness to histamine and distilled water.
In a randomized, cross-over study we compared the effects of inhaled nedocromil sodium, 4 mg q.i.d., with inhaled beclomethasone dipropionate, 200 micrograms q.i.d. in 23 atopic asthmatic patients. After a 3 week single-blind placebo period, regarded as the baseline, and after 4 and 8 weeks of active treatment, drug effects were assessed with regard to bronchial hyperresponsiveness to histamine...
متن کاملAnti-Allergic Cromones Inhibit Histamine and Eicosanoid Release from Activated Human and Murine Mast Cells by Releasing Annexin A1
BACKGROUND AND PURPOSE Although the 'cromones' (di-sodium cromoglycate and sodium nedocromil) are used to treat allergy and asthma, their 'mast cell stabilising' mechanism of pharmacological action has never been convincingly explained. Here, we investigate the hypothesis that these drugs act by stimulating the release of the anti-inflammatory protein Annexin-A1 (Anx-A1) from mast cells. EXPE...
