Abstract
Orally administered lodoxamide ethyl (U-42,718) inhibited anaphylactic reactions in a dose-related manner in the following test animals: (1) In the rat PCA reaction, excellent activity (75% inhibition at 0.1 mg/kg) was seen with a duration of activity of 30 min, (2) In the ascaris-sensitive primate (45% inhibition at 1.0 mg/kg) in lung parameters related to increased resistance and decreased compliance which persisted for up to 3 h, and (3) 50 mg/kg protected guinea pigs, sensitized to egg albumin, from lung function changes. Activity in these animal systems indicates that this orally active drug may hold promise in clinical asthma.
