The present invention relates to a pidolate salt and malate salt of a compound represented by a formula 1 with an excellent liquid-phase stability, solid-phase stability, water solubility, precipitation stability and hygroscopicity all together as a compound for preventing and treating diseases mediated by an acid pump antagonistic activity, as well as a method for preparing the same.
1. A method of treating a disease mediated by an acid pump antagonistic activity in a patient in need thereof, comprising administering to the subject a pharmaceutical composition comprising a therapeutically effective amount of a pidolate salt of a compound represented by Formula 1, wherein the disease is selected from the group consisting of gastroesophageal disease, gastroesophageal reflux disease (GERD), peptic ulcer, gastric ulcer, duodenal ulcer, an ulcer induced by NSAID, gastritis, Helicobacter pylori infection, dyspepsia, functional dyspepsia, Zollinger-Ellison syndrome, nonerosive reflux disease (NERD), visceral pain, purosis, nausea, esophagitis, dysphagia, salivation, an airway lesion, and asthma:
2. The method of claim 1 , wherein the disease is gastroesophageal reflux disease (GERD).
3. The method of claim 1 , wherein the disease is peptic ulcer, gastric ulcer, duodenal ulcer, or an ulcer induced by NSAID.
4. The method of claim 1 , wherein the disease is Helicobacter pylori infection.
5. The method of claim 1 , wherein the disease is nonerosive reflux disease (NERD).
6. The method of claim 1 , wherein the disease is esophagitis.
7. The method of claim 1 , wherein the pharmaceutical composition comprises an injection formulation.
8. The method of claim 7 , wherein the pharmaceutical composition comprises the pidolate salt of Formula 1 in an amount ranging from 1 to 100 mg/ml.
9. The method of claim 8 , wherein the pharmaceutical composition comprises the pidolate salt of Formula 1 in an amount ranging from 1 to 50 mg/ml.
10. The method of claim 1 , wherein the pharmaceutical composition comprises a formulation selected from the group consisting of a powder, granule, tablet, capsule, suspension, emulsion, syrup, aerosol, ointment, cream, and suppository.
11. A method of treating a disease mediated by an acid pump antagonistic activity in a patient in need thereof, comprising administering to the subject a pharmaceutical composition comprising a therapeutically effective amount of a malate salt of a compound represented by Formula 1, wherein the disease is selected from the group consisting of gastroesophageal disease, gastroesophageal reflux disease (GERD), peptic ulcer, gastric ulcer, duodenal ulcer, an ulcer induced by NSAID, gastritis, Helicobacter pylori infection, dyspepsia, functional dyspepsia, Zollinger-Ellison syndrome, nonerosive reflux disease (NERD), visceral pain, purosis, nausea, esophagitis, dysphagia, salivation, an airway lesion, and asthma:
12. The method of claim 11 , wherein the disease is gastroesophageal reflux disease (GERD).
13. The method of claim 11 , wherein the disease is peptic ulcer, gastric ulcer, duodenal ulcer, or an ulcer induced by NSAID.
14. The method of claim 11 , wherein the disease is Helicobacter pylori infection.
15. The method of claim 11 , wherein the disease is nonerosive reflux disease (NERD).
16. The method of claim 11 , wherein the disease is esophagitis.
17. The method of claim 11 , wherein the pharmaceutical composition comprises an injection formulation.
18. The method of claim 17 , wherein the pharmaceutical composition comprises the malate salt of Formula 1 in an amount ranging from 1 to 100 mg/ml.
19. The method of claim 18 , wherein the pharmaceutical composition comprises the malate salt of Formula 1 in an amount ranging from 1 to 50 mg/ml.
20. The method of claim 11 , wherein the pharmaceutical composition comprises a formulation selected from the group consisting of a powder, granule, tablet, capsule, suspension, emulsion, syrup, aerosol, ointment, cream, and suppository.
