Topically active inhaled corticosteroid (IC) drugs are highly effective for chronic asthma. Formalized conceptions of "high, low or safe" dosages of these drugs may be less appropriate than one of "optimal dosage". It seems reasonable to formulate a specific goal of treatment, and then fit dosage to the individual needs and tolerances of the patient rather than to a conventionalized "safe" limit, based on averaged data from different and perhaps quite dissimilar subjects. The studies reviewed here illustrate some principles applicable to the effective use of IC drugs.

Dysphonia is a known local adverse effect of inhaled corticosteroids. This symptom was investigated by laryngoscopy and assessment in a voice laboratory. The effects of changing the treatment of patients with dysphonia, reported whilst using the pMDI, to pMDI plus Nebuhaler or Tubuhaler was also assessed.. Seventy-two patients reporting dysphonia and taking inhaled steroids from a pMDI entered a 12-week, open, parallel group study. Fifty-one completed the study per protocol; 26 in the Nebuhaler group [21 female, mean age 57 years (22-77)] and 25 in the Turbuhaler group [18 female, mean age 58 years (21-81)]. A dysphonia diary card was completed weekly. Voice laboratory assessments and laryngoscopy were performed on entry and at 12 weeks.. There were no differences in voice laboratory data, laryngoscopic evidence of disordered glottic closure and diary data between the two groups at 12 weeks. At study entry laryngoscopic appearances were normal in almost half the patients. Vocal cord bowing was rarely seen. Glottic closure changed in nine patients during the study period, but there was no correlation with voice symptoms. The trend of symptomatic improvement of voice status in the Turbuhaler group did not correlate with voice laboratory assessments and laryngoscopic evidence of disordered glottic closure. After 4 weeks, 40% of patients using Turbuhaler and 8% in the Nebuhaler group scored their voice status as better (P < 0.02) but there was no significant difference between the two groups at 12 weeks (Turbuhaler 52%, Nebuhaler 23%, P=0.08).. This study does not support the view that dysphonia in asthmatics inhaling corticosteroids is usually caused by myopathic bowing of the vocal cord muscles.

The aim of the study was to carry out assessment of the respiratory function of patients with COPD undergoing a three month (600 microgram) treatment with an inhaled steroid--Budesonide. This was a double blind study carried out on 57 patients. During treatment with Budesonide a clinical improvement was seen. Respiratory function parameters did not alter throughout the 3 month treatment period, although bronchial reactivity diminished. Side effects were seen only in 3 patients--in all it was dysphonia. It seems that Budesonide can be added to other treatment protocols in patients with exacerbations of chronic bronchitis.

The aim of the study was to assess the prevalence of throat and voice symptoms in asthma patients using pressurized aerosol, metered-dose, inhaled corticosteroid preparations. A questionnaire was administered to hospital out-patients in an asthma clinic and to a control group attending a diabetic clinic. Two hundred and fifty five consecutive out-patients using pressurized aerosol inhaled corticosteroids and 100 controls were surveyed. One hundred and forty seven (58%) patients taking inhaled steroids reported voice dysphonia or throat symptoms compared with 13% of control patients. Women admitted to symptoms more frequently than men. Throat symptoms were more prevalent in patients using higher doses of inhaled steroid. Aerosol inhaler-induced cough was reported by 87 (34%) patients. Local side-effects were equally prevalent both with beclomethasone dipropionate and budesonide aerosol inhalers. The use of a large volume spacing device with either steroid aerosol did not appear to protect against these symptoms. Local side-effects are common in asthmatics taking pressurized aerosol, metered-dose, inhaled steroids.

The influence of the dosing regimen on the occurrence of oropharyngeal complications during a trial of the anti-asthmatic aerosol steroid budesonide was assessed by systematically varying the daily dose (400, 800, 1,600 micrograms), dose frequency (b.i.d. vs. q.i.d.), and dosing schedule (AM vs. AM/PM). Dysphonia was infrequent and was not affected by any features of the treatment regimen. ;Its incidence was unrelated to that of candidiasis. The amount of oropharyngeal candidiasis on the other hand correlated strongly with the daily dose of budesonide and dosing frequency. B.i.d. treatment abolished the effect of increasing budesonide dose on candidiasis, and virtually eliminated any need for nystatin. A 24 h interval between doses (using an AM schedule), or two intervals of about 12 h were both effective in conserving antifungal host defences in the oropharynx. Temporary conversion to b.i.d. dosing can facilitate the control or prevention of thrush, especially when the risk is increased by concomitant antibiotic therapy, as was shown to be the case in these patients. A small, but statistically significant, deterioration in peak expiratory flow occurred during b.i.d. dosing. Thus, despite its ability to virtually eliminate the problem of recurring thrush, b.i.d. dosing should not be continued indefinitely. These considerations probably apply to other topically active steroids currently used to treat asthma.

Nine of 14 asthmatic patients who presented with persistent dysphonia while taking inhaled corticosteroids had a bilateral adductor vocal cord deformity with bowing of the cords on phonation. This causes the dysphonia and usually occurs without candidiasis. It was seen with beclomethasone dipropionate (in both pressurised aerosol and dry powder preparations), betamethasone valerate, and budesonide. It was related to the dose and potency of inhaled steroid and may represent a local steroid myopathy. It was reversed when the inhaled steroid was stopped, although resolution sometimes took weeks. Laryngeal candidiasis may have contributed to the vocal cord abnormality in two of these nine patients. Of the five patients without vocal cord deformity, laryngeal candidiasis was the sole cause of dysphonia in three. In the remaining two dysphonia was thought to be psychogenic. The vocal cord deformity may exist subclinically. Of nine patients who started to take aerosol steroid and who were examined monthly for one year, three developed vocal cord deformity but only one had persistent dysphonia. Vocal abuse did not appear to contribute to dysphonia.
