A short-term double-blind trial of aerosol triamcinolone acetonide in steroid-dependent patients with severe asthma. 1976

R J Kriz, and F Chmelik, and G doPico, and C E Reed

Twenty-five steroid-dependent severely asthmatic patients, ranging in age from 20 to 67 years, were hospitalized. Baseline laboratory and pulmonary function testing was followed by reduction of prednisone therapy to 5 mg daily and by entry into a randomized double-blind study of placebo vs active aerosol triamcinolone acetonide (300mug four times daily). In this four-week trial, aerosol triamcinolone acetonide further reversed airway obstruction and proved to be an effective substitute for large oral doses of steroids in steroid-dependent patients with severe asthma. No significant improvement occurred in the maximum midexpiratory flow or the maximum velocity of air flow after 50 percent or 75 percent of the vital capacity had been expelled. There was no significant difference in the frequency of untoward effects between the groups taking aerosol triamcinolone acetonide and its vehicle. No patient demonstrated any definite return of adrenal function.

D010919 Placebos Any dummy medication or treatment. Although placebos originally were medicinal preparations having no specific pharmacological activity against a targeted condition, the concept has been extended to include treatments or procedures, especially those administered to control groups in clinical trials in order to provide baseline measurements for the experimental protocol.

D002986 Clinical Trials as Topic Works about pre-planned studies of the safety, efficacy, or optimum dosage schedule (if appropriate) of one or more diagnostic, therapeutic, or prophylactic drugs, devices, or techniques selected according to predetermined criteria of eligibility and observed for predefined evidence of favorable and unfavorable effects. This concept includes clinical trials conducted both in the U.S. and in other countries. Clinical Trial as Topic

D005541 Forced Expiratory Volume Measure of the maximum amount of air that can be expelled in a given number of seconds during a FORCED VITAL CAPACITY determination . It is usually given as FEV followed by a subscript indicating the number of seconds over which the measurement is made, although it is sometimes given as a percentage of forced vital capacity.
