routes_of_administration =Pentagastrin is a synthetic
polypeptide that has effects likegastrin when givenparenteral ly. It stimulates thesecretion ofgastric acid ,pepsin , andintrinsic factor , and has been used as a diagnostic aid as thepentagastrin-stimulated calcitonin test .Pentagastrin binds to the
cholecystokinin -B receptor, which is expressed widely in the brain. Activation of these receptors activates thephospholipase C second messenger system. When givenintravenously it causespanic attacks.Pentagstrin's IUPAC chemical name is "L-Phenylalaninamide, N-((1,1-dimethylethoxy)carbonyl)-beta-alanyl-L-tryptophyl-L-methionyl-L-alpha-aspartyl".
