...Tahir Ahmed; Ignacio Danta We studied the comparative modification of histamine- and methacholine-induced bronchoconstriction by a calcium antagonist, gallopamil, in 8 subjects with bronchial asthma. Dose-response curves to aerosolized methacholine or histamine were performed, without and following...
