Degradation of bronchodilator agents in oxymix system

Abstract: Known amounts of isoproterenol, phenylephrine, and epinephrine were added to the aqueous oxymix system and thereby exposed to potential redox destruction. Thirty minutes later, recoveries of isoproterenol and phenylephrine were 89-100% and 89-108%, respectively, while the recovery of epinephrine was 53-79%.
