to determine whether the combination of an agent thought to inhibit mediator release ( cromolyn ) and an agent that inhibits parasympathetic pathways inhibits sulfur dioxide-induced bronchoconstriction more than either agent alone , we measured the bronchomotor response of 9 asthmatic subjects to inhalation of sulfur dioxide after treatment with cromolyn sodium ( 200 mg by spinhaler ) , with atropine sulfate ( 2.0 mg by nebulizer ) , and with the 2 drugs given together .
