Ranitidine 22-32 tachykinin precursor 1 Homo sapiens 96-98 12495560-7 2002 Maximum plasma SP levels (21.3+/-5.2 and 22.8+/-4.2 pg mL(-1)) were reached 60 min after administration of ranitidine and nizatidine, respectively. Ranitidine 107-117 tachykinin precursor 1 Homo sapiens 15-17 12495560-9 2002 The released CGRP and SP by ranitidine and nizatidine administration may produce a gastroprotective effect, increase mucosal blood flow, and inhibit acid secretion in the gastrointestinal tract.
