Cromolyn sodium, a mast cell stabilizing agent, provides an immediate protective effect against the exercise-induced bronchoconstriction while being used before the exercise. However, cromolyn is ineffective in reversing asthmatic bronchospasm; it is used as a maintenance therapy and has a prophylactic role in chronic asthma. The purpose of this study was to determine the extent of change in ba...

BACKGROUND Inhalation therapy with sodium cromoglycate is recommended as the first-line prophylactic treatment for moderate asthma in children. The availability of spacer devices with face-masks has extended the applicability of metered-dose inhalers to younger children. We studied the feasibility and effects of this therapy compared with placebo in children aged 1-4 years. METHODS 218 childr...

We wished to determine whether nebulized sodium cromoglycate (SCG) has bronchodilator effects in very young children. In 18 children born prematurely and studied at a median of 15 months of age, thoracic gas volume (TGV) and airways resistance (Raw), were measured and hence specific airways conductance (sGaw) was calculated before (baseline) and after nebulized saline, and then after sodium cro...

An open assessment study was carried out during the summer of 1972 in which 2% sodium cromoglycate eyedrops were evaluated in the treatment of patients with vernal keratoconjunctivitis. A highly significant number of patients found the eyedrops effective, while a marked improvement was recorded in mild and moderate cases; in severe cases or in acute exacerbations additional steroid therapy was ...

A worker with occupational exposure to aluminum powder developed asthmatic symptoms three years and six months after starting work. Skin tests (prick and intradermal) to aluminum chloride (AlCl3) were negative. Inhalation challenge test with 10 mg of aluminum powder and 10 mg/ml of AlCl3 solution induced an early asthmatic response. Sodium cromoglycate pre-treatment reduced AlCl3-induced bronch...

The review of placebo controlled trials of sodium cromoglycate (SCG) in childhood asthma by Tasche et al concludes that “there is insuYcient evidence that SCG has a beneficial eVect as maintenance treatment in children with asthma”. We do not believe this conclusion is justified. The principal criteria for assessing the eYcacy of inhaled SCG are the mean diVerences in the eVect on the symptoms ...

To investigate whether mast cell degranulation was important in producing nocturnal asthma, the effect of a single high dose of nebulised sodium cromoglycate on overnight bronchoconstriction, oxygen saturation, and breathing patterns in eight patients with nocturnal wheeze was examined. The study took the form of a double blind placebo controlled crossover comparison. Treatment with cromoglycat...

A prospective study was undertaken to evaluate the efficacy of (sodium) cromoglycate in the treatment of persistent wheezing in 31 children between 4 and 12 months of age. The subjects were randomised to receive either 40 mg of cromoglycate (n = 16) or physiological saline as placebo (n = 15) three times a day by wet nebulisation in a double blind fashion for a period of six weeks. The patients...
