To determine the efficacy of nedocromil sodium in adult asthma patients using bronchodilators alone to control their disease, a consecutive sample of 127 patients with long-term asthma was studied for 16 weeks. The patients were maintained on sustained release theophylline preparations (SRT) and inhaled and oral beta-adrenergic bronchodilators (beta 2). One hundred sixteen patients (90 percent) completed the study; one placebo-treated patient withdrew owing to throat irritation and wheezing. Nedocromil sodium provided an additional benefit to adult patients receiving SRT and inhaled beta 2-agonists. With the exception of night-time asthma, nedocromil sodium maintained this improvement for the final 12 weeks of the study despite a reduction in concomitant bronchodilator therapy.

Fifty-one patients (22 male, 29 female) aged 22-60 years (mean age 41.2 years), predominantly extrinsic asthmatics, took part in this study, a follow-up to a 28-day, double-blind trial (Lal et al., Thorax 1984: 39: 809). Forty-four patients completed 12 months of treatment after a 4-week baseline; seven withdrew. A number of symptoms (e.g. coughing, wheezing, sore throat) were reported but none appeared particularly frequently; most were attributable to the technique of inhalation. After 4 weeks of treatment with nedocromil sodium (Tilade 4 mg q.i.d.), patients were encouraged to reduce use of inhaled corticosteroids (48 patients) and sodium cromoglycate (16). Inhaled bronchodilators were to be used as required and other medication was to continue as before. At the end of the study, 28 patients had stopped using inhaled steroids and 10 had significantly reduced the dosage (p less than 0.001, week 5 to end). Ten patients had stopped using sodium cromoglycate. Inhaled bronchodilator use was significantly reduced (p less than 0.001, weeks 1-8; p less than 0.05, weeks 9-12) early in the study but returned to baseline as inhaled steroid usage was reduced. Diary card assessments of wheezing and shortness of breath showed significant improvement, particularly in the early part of the study. Diary card PEFRs showed no marked changes but significant decreases, though small, were found in FEV1, FVC and PEFR on clinic visits. Clinical assessment showed improvement in the first half of the study; the differences were less marked as inhaled steroid usage declined. Final opinions of treatment effectiveness significantly favoured nedocromil sodium. This study demonstrates the acceptability, tolerability and safety of nedocromil sodium.(ABSTRACT TRUNCATED AT 250 WORDS)

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.

In a double-blind, double-placebo, randomized crossover study, we compared the effects of 6 wk of treatment with the anti-inflammatory drug nedocromil sodium (16 mg/day) with 6 wk of treatment with the bronchodilator drug albuterol (800 micrograms/day) in 29 adults with allergic asthma. After 3 and 6 wk of treatment with nedocromil sodium, patients were significantly less hyperresponsive to propranolol (p = 0.002 and p = 0.02) and almost significantly less hyperresponsive to histamine (p = 0.071 and p = 0.065). FEV1 and FVC percent predicted tended to be higher, morning PEF values increased significantly (p = 0.038 and p = 0.03), and diurnal and day-to-day PEF variation decreased (p = 0.03 and p = 0.093, p = 0.005 and p = 0.096, respectively) with nedocromil sodium treatment compared with albuterol treatment. Almost all symptoms (daytime and nighttime asthma, wheezing, shortness of breath) and the additional bronchodilator use were significantly reduced with nedocromil sodium treatment compared with albuterol treatment. Treatment with the anti-inflammatory drug nedocromil sodium was shown to be superior to treatment with the bronchodilator drug albuterol. The patient's clinical situation may deteriorate when beta 2-agonists are used continuously. Nedocromil sodium has good clinical effect, and it may serve as a first-line choice for antiinflammatory therapy in asthma.

Exercise-induced bronchospasm, exercise-induced bronchoconstriction, and exercise-induced asthma (EIA) are all terms used to describe the phenomenon of transient airflow obstruction associated with physical exertion. It is a prominent finding in children and young adults because of their greater participation in vigorous activities. The symptoms shortness of breath, cough, chest tightness, and wheezing normally follow the brief period of bronchodilation present early in the course of exercise. Bronchospasm typically arises within 10 to 15 minutes of beginning exercise, peaks 8 to 15 minutes after the exertion is concluded, and resolves about 60 minutes later, but it also may appear during sustained exertion. EIA occurs in up to 90% of asthmatics and 40% of patients with allergic rhinitis; among athletes and in the general population its prevalence is between 6% and 13%. EIA frequently goes undiagnosed. Approximately 9% of individuals with EIA have no history of asthma or allergy. Fifty percent of children with asthma who gave a negative history for EIA had a positive response to exercise challenge.6 Among high school athletes, 12% of subjects not considered to be at risk by history or baseline spirometry tested positive. Before the 1984 Olympic games, of 597 members of the US team, 67 (11%) were found to have EIA. Remarkably, only 26 had been previously identified, emphasizing the importance of screening for EIA even in well-conditioned individuals who appear to be in excellent health. The severity of bronchospasm in EIA is related to the level of ventilation, to heat and water loss from the respiratory tree, and also to the rate of airway rewarming and rehydration after the challenge. Postexercise decrease in the peak expiratory flow rate of normal children may be as much as 15%; therefore, only a decrease in excess of 15% should be viewed as diagnostic. EIA is usually provoked by a workload sufficient to produce 80% of maximum oxygen consumption; however, in severe asthmatics even minimal exertion may be enough to produce symptoms. Patients with normal lung function at rest may have severe air flow limitation induced by exercise,10 and as many as 50% of patients who are well-controlled with inhaled corticosteroids still exhibit EIA. A challenge of sufficient magnitude will provoke EIA in all patients with asthma. PHARMACOLOGIC THERAPY: Exercise, unlike exposure to allergens, does not produce a long-term increase in airway reactivity. Accordingly, patients whose symptoms manifest only after strenuous activity may be treated prophylactically and do not require continuous therapy. Most asthma medications, even some unconventional ones such as heparin, furosemide, calcium channel blockers, and terfenadine, given before exercise, suppress EIA. McFadden accounts for the efficacy of these disparate classes of drugs by their potential effect on the bronchial vasculature that modulates the cooling and/or rewarming phases of the reaction. Short-acting -agonists provide protection in 80% to 95% of affected individuals with insignificant side effects and have been regarded for many years as first-line therapy. Two long-acting bronchodilators, salmeterol and formoterol, have been found effective in the prevention of EIA.18-21 A single 50-microg dose of salmeterol protects against EIA for 9 hours; its duration appears to wane in the course of daily therapy. Cromolyn sodium is highly effective in 70% to 87% of those diagnosed with EIA and has minimal side effects. Nedocromil sodium provides protection equal to that of cromolyn in children. Children commonly engage in unplanned physical activity and sometimes are not allowed to carry their own medication. Thus, a simple long-acting regimen given at home is likely to be more effective than short-acting drugs that must be administered in a timely manner. Although the 12-hour protection by salmeterol reported by Bronsky et al may not persist with continued use, the 9-hour duration of action is
