title: A group comparative study of the safety and efficacy of nedocromil sodium (Tilade) in reversible airways disease: a preliminary report.
abstract: Nedocromil sodium in a dose of 4 mg b.i.d. or q.i.d. by inhalation was used to treat asthmatic patients in a double-blind, placebo-controlled, randomized, parallel study. 80 patients (39 active drug and 41 placebo) received q.i.d. dosage and 87 patients (45 active drug and 42 placebo) received b.i.d. dosage. The patients selected were not on oral or inhaled steroids but required oral sustained-release theophylline with or without an inhaled beta-agonist aerosol. There was a significant reduction in daytime asthma symptoms (p = 0.04) and asthma severity (p less than 0.01) 6 weeks after the onset of therapy in the nedocromil sodium q.i.d. treated group as compared with placebo. In the nedocromil sodium b.i.d. treated group, the following variables showed statistically significant improvements compared with placebo: daytime and night-time asthma (p = 0.002 in both instances), wheezing assessed by auscultation (p = 0.03) and overall asthma severity (p less than 0.01). All these variables showed improvements within 2 weeks of the onset of therapy and became statistically significant at 6 weeks. Side-effects were minor and occurred only in a small number of patients. It can be concluded from this study that nedocromil sodium is a safe and effective drug in the management of asthma.
