title: Clinical physiological data on the bronchodilator effect of Duovent versus salbutamol in chronic obstructive lung disease.
abstract: We studied the bronchodilator effect of a combination of fenoterol (100 micrograms) and ipratropium bromide (40 micrograms) (Duovent) versus salbutamol and placebo in 16 patients with chronic obstructive lung disease (COLD). FEV1 and the side-effects (palpitations, tremors, excitation) were measured at 0, 30, 60, 120, 240, 360 and 420 min after administration. The drugs were administered in aerosol form following a randomization schedule. The bronchodilator effect of Duovent was greater than that of salbutamol; moreover, Duovent had a lasting efficacy and few side-effects. Duovent is thus a useful drug therapeutically.
