Abstract
Summary: BRL 10833, a nitroindanedione, with DSCG like activity in rat immediate type hypersensitivity, shows good absorption after oral intake in man. The ingestion of 2 and 10 mg BRL 10833/kg body weight provides protection against the immediate type allergen induced bronchoconstriction in patients with bronchial asthma.These results confirm the activity of the drug already shown by inhalation.
