Beclomethasone dipropionate aerosol in the treatment of steroid-dependent asthma. A 12-week double-blind study comparing beclomethasone dipropionate and a vehicle aerosol.

In a randomized double-blind 12-week trial of steroid-dependent patients with chronic asthma, ten (59 percent) out of 17 patients receiving beclomethasone dipropionate aerosol in a total daily dose of 400mug were able to discontinue systemic corticosteroid therapy successfully, compared to two (13 percent) out of 15 patients in the placebo group (P=0.002). At the end of the trial, the average 8 am plasma cortisol level in the group receiving beclomethasone was more than twice the pretherapy value, whereas the level in the placebo group showed no significant change. There was no significant difference between the beclomethasone group and the placebo group in the overall incidence of side effects related to the aerosol and the effects of systemic corticosteroid withdrawal. Oral candidiasis was not found in any patient receiving beclomethasone dipropionate aerosol. Allergic nasal symptoms were disabling in many patients when the oral dosage of corticosteroids was tapered.

[Glucocorticoid action of beclomethasone and its propionate ester derivatives].

In the present pharmacokinetic studies on beclomethasone dipropionate in rats, it was suggested that most of the beclomethasone-17, 21dipropionate is transformed rapidly into beclomethasone-17-monopropionate or beclomethasone in the blood or tissues and exerts the glucocorticoid effect in the form of beclomethasone. Glucocorticoid activity of beclomethasone was revealed to be 1-10% that of dexamethasone both in the hypothalamopituitaryadrenocortical suppressive effect and liver tyrosine amino transferase inducing efect in rats. Beclomethasone and its propionate derivatives were shown to have higher binding affinity to glucocorticoid receptors in rat liver, thymus and hypophysis than that of dexamethasone. The experimental results herein may serve to explain why beclomethasone and its propionate derivatives showed such a weak glucocorticoid action in comparison with that of dexamethasone. The amounts of receptor-beclomethasone (or its propionate derivatives) complexes which bound specifically to liver nuclei were only 10% or less than those of receptordexamethasone complexes and the in vivo metabolism of beclomethasone and beclomethasone-dipropionate was more rapid than that of dexamethasone.

Beclomethasone dipropionate inhaler: a review of its pharmacology, therapeutic value and adverse effects. I: Asthma.

Beclomethasone dipropionate is a topically active corticosteroid used as an adjuvant in the control of chronic asthma when given by inhalation as an aerosol. It is not intended for treatment of acute attacks. It appears that the main difference between beclomethasone dipropionate and other corticosteroids previously used by inhalation is its high topical activity together with a lower systemic activity due to metabolic inactivation of the swallowed portion of the dose. Clinical experience has shown that at doses of 200 to 600mug daily, beclomethasone dipropionate inhaler is preferable to oral corticosteroids, because of lack of side-effects, when adult patients and children who are inadequately controlled by full doses of sodium cromoglycate and bronchodilators, are first considered to need maintenance corticosteroids. Inhaled beclomethasone dipropionate can allow a worthwhile reduction in maintenance doses of systemic corticosteroids in many patients already receiving these drugs and can replace systemic steroids entirely in some patients, particularly when their initial dose of steroids is less than 10mg daily of prednisone or its equivalent. Substitution should be attempted when the patient's asthma is well controlled on their usual doses of systemic steroids and full doses of other adjuvant therapy. Withdrawal of systemic corticosteroids should be performed slowly and carefully. Because recovery from impaired adrenocortical function caused by prolonged systemic steroid therapy is usually slow, special care is necessary for 9 to 12 months after transfer to beclomethasone dipropionate aerosol until the hypothalamo-pituitary-adrenal axis has sufficiently recovered to cope with emergencies such as trauma, surgery, severe infections or an acute attack of asthma. It is essential that additional therapy including high doses of systemic corticosteroids be used immediately to control any acute exacerbation of asthma which occurs during maintenance therapy with beclomethasone dipropionate aerosol. Tests of adrenal function suggest that beclomethasone dipropionate at dosages of 400 to 800 mug daily has little or no adverse effect. The most common side-effect associated with the continuous use of beclomethasone dipropionate inhaler has been oropharyngeal candidiasis, which appears to be dose-related and more common in women than in men. Systemic steroid withdrawal effects, like being generally unwell, and exacerbation of underlying allergic diseases such as allergic rhinitis, have been reported after substitution of beclomethasone dipropionate inhaler for systemic steroids. However, systemic withdrawal effects seldom occur if systemic steroids are withdrawn slowly.

Treatment of steroid-dependent asthma patients with beclomethasone dipropionate aerosol.

Fifty-two steroid-dependent adults with chronic perennial asthma were transferred to beclomethasone dipropionate aerosol. The tests demonstrated a significant improvement with beclomethasone in terms of the diary score, bronchodilator use, and PEF and FEV1.0 measurements, as compared with the previous period of prednisolone treatment. Before the transfer, 26 of the patients displayed one or more diseases or symptoms which were probably due to systemic steroid medication. Morning cortisol levels, along with the response to tetracosactrin had in all cases returned to normal when tests were carried out 41 days after transfer to beclomethasone dipropionate. In a group of 12 patients with the lowest 11-OHCS basal values, the mean of their 11-OHCS values during prednisolone treatment was as low as 0.14 plus or minus 0.06 mumol/l, but tetracosactrin challenge induced an elevation to a normal level, 0.33 plus or minus 0.13 mumol/l. After 41 days of beclomethasone treatment, the corresponding values were 0.56 plus or minus 0.90 plus or minus 0.28 mumol/l. Thirty-seven patients experienced one or more disturbing symptoms after transfer to beclomethasone. In many cases, the symptoms of allergic rhinitis were troublesome and persistent leading to a sixfold increase in the use of antihistaminic tablets. When the patients had learned to exhale through the nose following beclomethasone inhalation, the use of antihistaminic tablets again diminished to some extent. Moreover, two cases of ulcerative colitis were encountered during the beclomethasone treatment. During a follow-up period of one year, 14 patients were again receiving prednisolone; most often, this was due to worsening of the asthma because of respiratory infections. During the beclomethasone treatment, a continuous significant improvement in PEF was noted after isoprenaline inhalation, suggesting that further benefit may be obtained by the employment of bronchodilator aerosols as an essential part of the treatment.

Double-blind trial comparing two dosage schedules of beclomethasone dipropionate aerosol with a placebo in chronic bronchial asthma. Second report of the Brompton Hospital/Medical Research Council Collaborative Trial.

A follow-up study to 52 weeks is reported on 95 corticosteroid-dependent asthmatics who took part in a double-blind, controlled trial of beclomethasone dipropionate for 28 weeks. During the 28 weeks two dosage schedules (800 microgram and 400 microgram daily) were compared with a placebo. If the corticosteroid tablet dosage had been at least halved and the clinical condition was satisfactory, the allocated regimen was continued 'blind' for the second period (29-52 weeks); 51 patients continued for this period, 46 on beclomethasone dipropionate. If progress was unsatisfactory, known beclomethasone dipropionate 800 microgram daily was substituted, the supervision remaining unchanged, the clinical supervisors remaining unaware which schedule had been received during the first 28 weeks. Nearly all the patients who at least halved their corticosteroid tablet dosage by 28 weeks continued to do well up to 52 weeks on the allocated regimen. When the placebo patients with unsatisfactory progress at 28 weeks were changed to 800 microgram beclomethasone dipropionate they showed a substantial improvement. Patients changed from 400 to 800 microgram showed little improvement on average. Approximately 30% of the whole group of patients failed to have their dosage of corticosteroid tablets, despite receiving 800 microgram beclomethasone dipropionate daily for six or more months. The cumulative incidence of 'oral candidiasis' (as defined for this report) in placebo patients changed at 28 weeks to 800 microgram beclomethasone dipropionate daily was 30% at 36 weeks and 43% at 52 weeks. Of eight patients increased from 400 microgram to 800 microgram daily, one had 'candidiasis' by 36 weeks and three by 52 weeks. Oral candidiasis was often asymptomatic and never led to the discontinuation of the corticosteroid aerosol, although the dosage was reduced in nine of the 30 who received 800 microgram beclomethasone dipropionate during the first 28 weeks. The incidence of bacterial infections in patients on beclomethasone dipropionate was similar to that of the placebo group and systematic laboratory investigations revealed no increase in the rate of isolation of potential pathogens.

Minimum dose requirements of steroid-dependent asthmatic patients for aerosol beclomethasone and oral prednisone.

In 34 steroid-dependent asthma patients who improved markedly during 2 mo of treatment when progressively larger doses of beclomethasone aerosol were added to their oral prednisone regimen, we subsequently reduced both steroids to ascertain the minimum dose of each needed to prevent recurrence of significant asthmatic disability. After 80 wk of follow-up, 15 patients had successfully terminated oral prednisone; 19 were better controlled with a combination of aerosol plus oral steroid than with either drug alone; all patients previously unable to convert to alternate-day prednisone did so successfully during the combined therapy. The minimum effective maintenance dosage varied greatly among these patients-the median values being 2.5 mg prednisone and 1,200 microgram beclomethasone per day. The latter ranged from 200 to 1,8000 microgram. Only 4 patients were satisfactorily controlled without prednisone on 400 microgram beclomethasone per day or less. Seven needed extra intranasal beclomethasone to help control the nasal polyps which worsened after prednisone withdrawal. Suppression of plasma cortisol levels, apparently attributable to the beclomethasone, persisted in most patients, but on the average this was no worse than before commencing this treatment and valuable clinical improvement accrued. There were no other important complications of the regimen. In most of these patients with severe chronic asthma, optimum control of the disease required combined aerosol-oral therapy and maintenance doses of beclomethasone higher than those usually recommended. In some patients, effective control of chronic asthma by beclomethasone treatment may require acceptance of some persisting suppression of adrenal function as a considered risk.

Subsittution of inhaled beclomethasone dipropionate for ingested prednisone in steroid-dependent asthmatics.

The effect of inhaled beclomethasone dipropionate (dose, 400 mug daily) was investigated in 31 prednisone-dependent asthmatics. In a double-blind noncrossover study of 25 patients dependent on a daily prednisone dose of 17.5 mg or less, the dose of ingested prednisone was significantly diminished through the use of beclomethasone as compared with placebo (P < 0.001). In a subsequent single-blind study of the 12 patients who had received placebo, a similar decrease in prednisone dose was possible when these patients received beclomethasone. In all 25 patients the effect of beclomethasone was maintained for 2 years; 9 came to require less beclomethasone and 1 required more. In an additional single-blind study of six patients with severe asthma, dependent on prednisone in a dose of 20 to 25 mg/d, the response to beclomethasone was more variable and less significant (P < 0.01). However, at 2 years there was no significant benefit (P > 0.05) and there were two treatment failures.In patients in whom reduction of dose or discontinuation of prednisone was possible plasma cortisol values before and after corticotropin administration increased significantly (P < 0.001). Prednisone reduction was associated with the appearance of mild musculoskeletal steroid-withdrawal symptoms of short duration in 15 patients, and recurrence of symptoms of rhinitis in 15 patients. Side effects of beclomethasone included episodes of hoarseness in 6 and easily treated oropharyngeal Candida albicans infection in 14.

A graded dose assessment of the efficacy of beclomethasone dipropionate aerosol for severe chronic asthma.

In a 26-wk double-blind controlled study of 34 patients whose asthma had been poorly controlled despite oral steroids, valuable clinical and pulmonary function improvement was derived by adding beclomethasone aerosol to the prednisone regimen. The amount of improvement correlated linearly with beclomethasone dosage over the range 200 to 1,600 microng/day. These patients required relatively high dosage. Success in achieving asymptomatic status was only 26% with the conventional 400 microng/day and 60% at 1,600 microng/day. Oropharyngeal candidiasis was also dose-related but did not prohibit the use of high-dosage beclomethasone. Respiratory infections, physical signs, blood glucose, and electrolytes were unaffected by the drug. A dose-related suppression of cortisol secretion was demonstrated, but about 1/4 of the group had normal plasma cortisol even at 1,600 microng/day plus the oral prednisone. An individualized risk-benefit assessment seems a better basis for choosing an optimal beclomethasone regimen for each patient than adherence to a conventionalized fixed dosage of 400 microng/day. This requires definition of: (1) a specific goal of treatment in the individual patient and the beclomethasone dosage required to achieve it; (2) the adrenocortical functional response of that particular patient to the desired dose of beclomethasone; and (3) the presence and degree of any dose-limiting constraints such as preexisting complications of steroid use.

Steroid-dependent asthma treated with inhaled beclomethasone dipropionate. A long-term study.

The efficacy of inhaled beclomethasone dipropionate has been examined in 44 steroid-dependent asthmatics observed for 9 months to 2 years. A 3-month double-blind trial found that subjects treated with beclomethasone had a significant diminution in symptoms, were able to reduce their use of medication, and had improved maximum expiratory flow rates. Approximately one half were able to discontinue the use of oral prednisone within 9 months after starting beclomethasone, and a further one third reduced their dose by at least 50%. No characteristics could be defined to predict responsiveness to beclomethasone. The effectiveness of beclomethasone was sustained for as long as 2 years and was not associated with any abnormal urine, blood, or serum values or chest X-ray findings. Candidiasis of the palate appeared in approximately one third of the subjects and was usually transient. The chronic use of beclomethasone did not result in endocrine suppression.

A comparison of oral choline theophyllinate and beclomethasone in severe perennial asthma in children.

Fourteen children with perennial asthma previously treated with beclomethasone dipropionate were studied for four months in a crossover trial to compare the efficacy of choline theophyllinate and beclomethasone dipropionate aerosol in the control of their symptoms. Assessments were made using twice daily peak flow measurements, together with daily records of symptom scores and use of extra salbutamol. Beclomethasone and oral choline theophyllinate together improved control of asthma in comparison with beclomethasone alone. Reduction of the dose of beclomethasone from 400 microgram/day caused worsening of asthma. Oral choline theophyllinate did not prevent this deterioration and therefore cannot replace beclomethasone for the long-term treatment of such asthmatic patients.

Beclomethasone in steroid-dependent asthma. Effective therapy and recovery of hypothalamo-pituitary-adrenal function.

Beclomethasone dipropionate was administered by aerosol to 30 patients whose chronic bronchial asthma required oral corticosteroid therapy. During the initial 12 weeks of the trial, beclomethasone therapy could be discontinued in 12 of 16 patients in contrast to only one of 14 patients receiving the inert aerosol placebo. Patients receiving the placebo were then given beclomethasone, and prednisone therapy was discontinued in five more. During six months of observation, adrenal function improved and steroid toxic reactions decreased in patients in whom oral corticosteroid therapy had been discontinued. Beclomethasone aerosol was generally well-tolerated. Asymptomatic thrush developed in four patients and rhinitis developed in ten patients as prednisone therapy was discontinued.

Long-term effects of beclomethasone dipropionate on prednisone dosage in the corticosteroid-dependent asthmatic.

The average prednisone dosage of 54 corticosteroid-dependent asthmatics was computed for one year prior to initiation of beclomethasone dipropionate. This was compared to the average prednisone dosage after nine months on the beclomethasone with progressive tapering of prednisone to either dose compatible with control of asthma or discontinuation. Beclomethasone was found clinically useful in the great majority of these patients because it permitted a significant decrease in dosage of prednisone, a change from daily to alternate-day prednisone, or discontinuation of prednisone after cautious tapering. The first two advantages were most evident in those asthmatics who initially required higher doses of oral steroids while the latter was evident in those requiring lower doses. Those patients whose prednisone dosage does not appear to be beneficially affected by the use of beclomethasone should be suspect as to adherence to proper medical dosage schedule.

Inhaled beclomethasone dipropionate in allergic bronchopulmonary aspergillosis. Report to the Research Committee of the British Thoracic Association.

A double-blind multi-centre study was carried out to assess the effects of beclomethasone dipropionate aerosol on the control of symptoms of asthma and on fungal colonization of the bronchi, in patients with allergic bronchopulmonary aspergillosis who had not been treated with an inhaled corticosteroid preparation for at least six months. Each of the 32 patients who completed the trial was treated with beclomethasone (100 microgram four times daily) or placebo aerosol for consecutive periods of six months without alteration of the pre-study maintenance therapy. Treatment of exacerbations of asthma and of pulmonary eosinophilia was left to the discretion of the participating physicians. The only statistically significant finding was an association between serum Aspergillus antibody levels and episodes of pulmonary eosinophilia diagnosed by radiography. During treatment with beclomethasone improvement occurred in ventilatory function and control of asthma, but Aspergillus fumigatus was detected in the sputum more frequently than during the placebo period. None of these trends attained statistical significance. Episodes of pulmonary eosinophilia were not reduced by beclomethasone and usually occurred without clinical deterioration of asthma.

Effects of inhaled beclomethasone dipropionate and alternate-day prednisone on pituitary-adrenal function in children with chronic asthma.

Two corticosteroid regimens, alternate-day prednisone and inhaled beclomethasone dipropionate, have been more acceptable than daily oral corticosteroids for treatment of chronic asthma. To compare the effect of these regimens on hypothalamic-pituitary-adrenal function, 20 children with asthma were evaluated while receiving 20 to 40 mg of prednisone on alternate mornings or 400 to 800 microgram per day of inhaled beclomethasone dipropionate in divided daily doses; seven children requiring only non-corticosteroid medication served as controls. Early-morning serum cortisol concentration, urinary free-cortisol excretion and the 11-desoxycortisol response to metyrapone were decreased to a similar degree among children receiving both corticosteroid regimens in comparison with the control patients and were lowest when alternate-day prednisone and inhaled beclomethasone dipropionate were given together. Thus, inhaled beclomethasone dipropionate appears similar to alternate-day prednisone in its effect on hypothalamic-pituitary-adrenal function when used alone; the effect is additive when the two are used together.

A prospective study of respiratory infection in asthmatic patients treated with beclomethasone dipropionate and sodium cromoglycate.

A prospective study of forty adult asthmatic patients attending two chest clinics in the City of Liverpool was undertaken. All patients had reversible airways obstruction and were under treatment with either beclomethasone dipropionate or sodium cromoglycate. Satisfactory symptomatic control was achieved in both groups of patients on a subjective basis, but there was a statistically significant (P less than 0-001) reduction in the number of admissions to hospital in the treatment year compared to the preceding 12 months in the beclomethasone aerosol group. No increased incidence of lower respiratory tract infections or non-specific sore throats was found in either group studied. No cases of clinical oral Candida infection occurred in the beclomethasone aerosol treated patients. It is concluded that beclomethasone dipropionate in aerosol form is not only a safe and effective method for symptomatic control of adult bronchial asthma but is also economically worthwhile as a means of reducing hospital admissions in this vulnerable group of patients.

The endocrinometabolic effects of beclomethasone dipropionate in asthmatic patients.

The endocrinometabolic effects of the aerosol administration of beclomethasone dipropionate (100 microng four times daily) were evaluated in 20 asthmatic patients (11 corticodependent and nine noncorticodependent) during one month. In the noncorticodependent group, aerosol administration of beclomethasone had no statistically significant effect on the results of the glucose tolerance test and the plasma levels of insulin; there was a slight decrease in basal levels of cortisol, but the response of the cortisol level to administration of ACTH remained quite normal. In corticodependent patients, after substitution of aerosol therapy with beclomethasone for the oral therapy with steroids, the depression of adrenal function disappeared, usually quickly (in less than one month), whereas the abnormalities in the results of the glucose tolerance test persisted. Thus, at the dosage used, beclomethasone dipropionate might have minor systemic endocrinometabolic effects.

Effect 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 and distilled water, lung function and beta 2-agonist use. After 4 and 8 weeks of treatment, nedocromil sodium reduced the histamine responsiveness (p < 0.005 and p < 0.0005), but not the distilled water responsiveness, and did not improve lung function and peakflow measurements compared to baseline. After 4 and 8 weeks of treatment, beclomethasone caused a significant increase in lung function (p < 0.005) and decrease in bronchial hyperresponsiveness to histamine (p < 0.0005) and distilled water (p < 0.0005) as compared to baseline. beta 2-agonist use was significantly diminished after an 8 week treatment with beclomethasone, whereas nedocromil sodium had no effect. Treatment with beclomethasone was superior to treatment with nedocromil sodium with regard to bronchial hyperresponsiveness to histamine and distilled water (p < 0.0005 and p < 0.005), lung function (p = 0.003), peakflow measurements (p < 0.05) and beta 2-agonist use (p < 0.005).

Treatment of vasomotor rhinitis with intranasal beclomethasone dipropionate (Becotide). Results from a double-blind cross-over study.

The effect of beclomethasone dipropionate (Becotide) intranasally in vasomotor rhinitis has been studied on 39 adult volunteers in a double-blind cross-over study during 9 weeks in February-April 1975. The dose of beclomethasone dipropionate was 300 mug/day. Twenty-five patients preferred the beclomethasone dipropionate period, 5 patients the placebo period, and 9 patients had no preference. About three-quarters (74 per cent) of the patients considered themselves free of symptoms or greatly improved after the treatment with beclomethasone dipropionate. Statistical calculation of the daily nasal symptoms score confirms the improvement. The speediest effect was registered for sneezing, followed by nasal catarrh, nasal itching, and blocking. No changes in the levels of cortisol occurred during the treatment. The bacteriological and mycological findings (analysed with regard to Candida albicans) were fairly constant.
