Terfenadine 93-104 histamine H1 receptor Cavia porcellus 53-74 10556670-1 1999 Terfenadine, a histamine H(1) receptor antagonist, has been associated with clinical ventricular arrhythmias and in vitro excitation-conduction blocks, whereas anti-ischemic and antiarrhythmic effects have been shown with cicletanine, a prostacyclin generation stimulator. Terfenadine 0-11 histamine H1 receptor Cavia porcellus 15-38 8001268-0 1995 Cardiac electrophysiological actions of the histamine H1-receptor antagonists astemizole and terfenadine compared with chlorpheniramine and pyrilamine. Terfenadine 93-104 histamine H1 receptor Cavia porcellus 44-65 6129862-5 1982 The unsurmountable antagonism of histamine by terfenadine may result from a slow dissociation of terfenadine from the histamine H1-receptor. Terfenadine 46-57 histamine H1 receptor Cavia porcellus 118-139 6129862-7 1982 It is concluded that terfenadine is a potent, selective histamine H1-receptor antagonist; the kinetics of association/dissociation of terfenadine with histamine H1-receptors may account for the long-lasting antihistaminic effect in various animal models. Terfenadine 21-32 histamine H1 receptor Cavia porcellus 56-77
