|Title:||Asthma treatment by inhalation of micronized N,N-diethyl-4-methyl-1-piperazinecarboxamide pamoate|
|Abstract:||Asthma is effectively treated by inhalation of powder dispensed from an aerosol suspension of powdered N,N-diethyl-4-methyl-1-piperazinecarboxamide pamoate, which is dispersed as a fine powder, essentially below 10 microns in particle size, which gives an improved ratio of absorption in the lungs as compared to systemic absorption.|
