Starting with khella, the traditional remedy for asthma Altunyan discovered in 1965 that the active ingredient of khella is khella. He eventually produced a safer chemical called sodium chromogylate. It was later sold as Intal by Fisons Pharmaceuticals, which it acquired from Ron-Pollenk Rohr, which in turn acquired Aventis և [[sanofi-aventis. Prior to the acquisition of RPR, Fisons’s R&D component was sold to Astra, making it part of AstraZeneca. Sodium chromogylate was the first clinically used mast cell stabilizer. Clogs play a very important role in the inflammation of allergies and asthma. Mast cells contain powerful inflammatory mediators that cause inflammation և by bronchoconstriction. Sodium chromoglate stabilizes the cell, preventing the release of mediators.
