Bilastine shows a long drug-target residence time at the H1 receptor (73 ± 5 min) and this results in a prolonged H1 receptor antagonism in vitro (Ca2+ mobilization in Fluo-4 loaded HeLa cells), following a washout of unbound antagonist. Hence, the long residence time of bilastine can explain the observed long duration of drug action in vivo.
