The stability of omeprazole in the aqueous solutions containing loxoprofen or Sodium bicarbonate was examined at room temperature. Loxoprofen or Sodium bicarbonate (60 mg) was added to omeprazole (600 ${\mu}g$/ml) solution to check the stability profile. Then, the solution was kept at room temperature for 80 hours. The concentration was assayed at each concentration by stability-indicating High performance liquid chromatography (HPLC) method. Aliquots of the solution were withdrawn at specified time intervals and assayed by chromatographic analysis for intact omeprazole. The relation between omeprazole concentration and peak area was linear from 5 to 160 ${\mu}g$/ml. The analysis method was precise with relative standard deviation (% RSD) no greater than 3.05 %. The remaining percentage-time curves revealed that omeprazole was degraded rapidly as functions of time and temperature following pseudo first-order kinetics. In conclusion, the stability of omeprazole was significantly affected by liquid solutions mixed with alkalizer (Sodium carbonate) or the NSAIDs (loxoprofen).

Endoscopic diagnosis and medical management from K43 and C45 patients, whose sex, occupation, character and life patterns are quite different each other, were discussed. The K43 was patient with erosive gastritis, which may caused by maldietary habits and life stresses. Although the effective drugs such as H2-receptor antagonists with atacids, H+/K+-pump inhibitors, prokinetics, colloidal bismuth, and sucralfates, were administrated for long time, symptomatic relief of abdominal pain was not improved. The tests of clinical phathology and abdominal sonogram were normal, visceral hypersensitivity was appeared from barostat test of stomach. However C45 had taken headache during every day life, and endoscopically confirmed as a gastric·duodenal ulcer patiant, which may caused by chronic use of NSAIDs. The her ulceric symptoms were suppressed from active stage to healing stage by using combination therapy for H. pylori with traditional antipeptic ulcer drugs, where as amitriptyline was administrated to the K43 but not effective. Nonulcer dyspepsia and irritable bowel syndrome is pooly defined, and affect about 15% of the population annually in U. S. A. but don't seek medical care. Author would like to point out that statistics for visceral pains are absent in Korea.

The aim of the study was to observe the influence and related mechanism of rebamipide on the intestinal contraction. Intestinal contraction includes the activation of thick or thin filament regulation. However, there are few reports addressing the question whether this regulation is involved in rebamipide-induced regulation. We hypothesized that rebamipide plays a role in intestinal contraction evoked by carbachol in rat intestine. Interestingly, rebamipide alone didn't inhibit and rather slightly increased the contraction in the denuded muscle. Therefore, rebamipide alone and together with indomethacin increases the ileal contraction suggesting that additional pathways might be involved in the regulation of ileal contractility. In conclusion, rebamipide has some effect on the regulation of contractility and anti-ulcer by NSAIDs.

This paper aims to analyze the effects that marketing mix variables have on the marketing performance of pharmaceutical manufacturers. It examines how product characteristics, price, marketing channel and promotion effort influence the sales and market share of anti-ulcer drugs in the markets for clinics and hospitals separately. Empirical results from 29 products of anti-ulcer drugs show that sales in hospitals are affected by the profit per prescription to the physician, brand name drugs relative to generics, and the age of ingredients since its introduction to the markets. Profit per prescription to the hospital, relative price, age of ingredients and promotion effort have positive effects on the market share.

Helicobacter pylori is an important transmissible human pathogen found on the luminal surface of the gastric epithelium. The organism can persist in the stomach indefinitely and causes gastroduodenal inflammation that may proceed to atrophic gastritis, peptic ulcer, gastric MALT lymphoma, and gastric cancer. Standard triple therapy which consists of proton pump inhibitor (PPI) plus two antibiotics (amoxicillin and clarithromycin) is now generally used in Korea, however, eradication rates of H. pylori has been decreasing due to increasing antibiotic resistance. In this review, current second-line treatment regimens, difficult problems on treatment, necessity of local target therapy, applicability of clay minerals as a drug delivery system (DDS), and a new therapeutic strategy and its study plans will be discussed.

Purpose: The aim of this study was to evaluate the clinical characteristics, endoscopic findings and risk factors related to the upper gastrointestinal bleeding (UGIB) seen in full-term infants. Methods: A clinical analysis for 9 cases with UGIB confirmed by endoscopy was carried out retrospectively. Patients were admitted to the Department of Pediatrics, Eulji Hospital, from January to December 2003. Results: UGIB from gastric or duodenal mucosal lesions has been seen in 0.13% in newborns infants. All patients were full-term AGA neonates without asphyxic findings at birth. Hematemesis, melena or recurrent vomiting developed within $4.4{\pm}3.8days$ after birth. Vital sign and laboratory test was normal on admission. Endoscopic findings showed hemorrhagic gastritis in 6 cases and peptic ulcers in 3 cases. All patients were successfully managed by medical treatment for $18.6{\pm}5.0days$. On treatment, clinical symptoms improved within $0.9{\pm}0.3days$. Follow-up endoscopy was not performed because there was no recurrence of symptoms in all patients. Case mothers had no history of gastritis, ulcer or anti-ulcer medications before and during pregnancy. Conclusion: If the healthy full-term infants express UGIB within a few days after birth, it is necessary to take careful history of family, mother and delivery process and to practice endoscopy for mucosal lesions of the patients. A follow-up endoscopy dose not seem to be necessary if the infant is clinically well.

The effect of pH and magnesium ion on the hydrolysis of dicyclomine HCl was investigated by comparing the rate constant and activation energy. The hydrolysis of dicyclomine HCl was acid-base catalytic reaction and the most stable range of pH was $3{\sim}5$. The magnesium ion accelerated the hydrolysis of dicyclomine HCl in aqueous solution.
