title: The protective effect of inhaled BRL 10833 on allergen induced bronchospasm.
abstract: BRL 10833, a nitroindanedione, with similar inhibitory activities to DSCG on the immediate type IgE mediated hypersensitivity in the rat, has been shown, when inhaled in a dose of 40 mg, to protect against allergen induced bronchospasm. A significant protective effect of BRL 10833 on the immediate bronchial reaction was seen in five out of ten patients. A single inhalation of 40 mg BRL 10833 seems also to have some protective effect on the late bronchial reaction, following an immediate reaction.
