Abstract: The present invention is related to novel oral compositions comprising an irreversible gastric H+/K+-ATPase proton pump inhibitor (PPI) as a gastric acid secretion inhibitor and one or more small carboxylic acid molecules as parietal cell activators in the gastric lumen. Unexpectedly, the compositions of the present invention are capable of enhancing the anti-acid activity of PPI in the stomach. The present invention further relates to a method of using such compositions to reduce gastric acid secretion in a mammal.

Abstract: The present invention discloses oral compositions comprising pentagastrin (PG) as an effective diagnostic agent for gastric acid secretion. The composition further comprises one or more agents that preserve the availability of PG in the gastric fluids, so that the biological activity of PG is maintained. The pharmaceutical compositions according to the present invention can be applied as diagnostic agents in the determination of the maximum gastric acid secretion as well as therapeutics.

Abstract: The present invention is related to novel oral compositions comprising an irreversible gastric H+/K+-ATPase proton pump inhibitor (PPI) as a gastric acid secretion inhibitor, pentagastrin (PG) or a PG analogue as an activator of parietal cells in the gastric lumen. In a preferred embodiment, the composition further comprises at least one agent that preserves the availability of PG in the gastric fluids, thus enabling PG to act locally in the stomach. Unexpectedly, the compositions of the present invention exhibit anti-acid activity locally in the stomach that is meal-independent, exhibit fast onset and prolonged inhibition of acid secretion.

Abstract: The present invention relates to methods for treating pathological conditions associated with Helicobacter sp infections, specifically H. pylori infection. The present invention further relates to methods for treating pathologies characterized by excess gastric acid secretion. The methods of the present invention comprise oral administration of pentagastrin effective locally in the stomach in conjunction with a gastric proton pump inhibitor. It is disclosed herein for the first time that PG administered orally exerts a local effect in the stomach and may be used in combination with a PPI for treating pathological conditions characterized by excess gastric acid secretion and in pathological conditions associated with Helicobacter sp infections.

Abstract: A biomedical system for targeted delivery of a therapeutic agent to a tissue region of a subject is provided. The biomedical system comprises: (a) a biomedical device including: (i) a device body designed and configured for implantation within the tissue region of the subject; and (ii) a first member of a binding pair attached to a surface of said device body; and (b) a delivery vehicle including: (i) a carrier particle designed for carrying the therapeutic agent; (ii) a second member of said binding pair attached to said carrier particle, said second member of said binding pair being capable of specifically interacting with said first member of said binding pair thereby enabling targeting of said delivery vehicle to said biomedical device when implanted within said tissue region.
