Transcript

  • 1. Omeneu Instant (Omeprazole +Sodiumbicarbonate)
  • 2. Digestive System • Esophagus( tube that connects your mouth and your stomach) • Stomach • Small Intestine • Large Intestine • Gall bladder • Liver • Pancreas
  • 3. Stomach • A stretchy bag that holds your food after you eat. Stomach has 4 major roles in human body. • • • • Esophagus To store food To mix the food with HCl and pepsin To reduce the size of food particles To empty the partially digested food into the small intestine Stomach
  • 4. Stomach Cells • Parietal cells (oxyntic cells) are the stomach epithelium cells which secrete gastric acid. • Parietal cells produce gastric acid (hydrochloric acid) in response to histamine (via H2 receptors), acetylcholine (M3 receptors) and gastrin (gastrin receptors). • Parietal cells contain an extensive secretary network (canaliculi) from which the HCl is secreted by active transport into the stomach.
  • 5. Acid-Related Pathophysiology The stomach secretes: • Hydrochloric acid (HCl) • Bicarbonates • Pepsinogen • Mucus • Prostaglandins
  • 6. Gastroesophageal Reflux Disease (GERD • Most common disorder of esophagus • Characterized by regurgitation of gastric contents into esophagus and exposure of esophageal mucous to gastric acid and pepsin. • Main symptom is heart burn – occurs after eating.
  • 7. Complications of GERD • Esophagitis, stricture or ulcer • Barrett’s Esophagus
  • 8. Peptic Ulcer • Condition characterized by Erosion of GI mucosa resulting from digestiveaction of HCl and pepsin • Ulcer development – Lower esophagus – Stomach – Duodenum
  • 9. Gastric Ulcer • common in late middle age – incidence increases with age • Use of NSAIDs - associated with a three- to four-fold increase in risk of gastric ulcer • Less related to H. pylori than duodenal ulcers – about 80% • 10 - 20% of patients with a gastric ulcer have a concomitant duodenal ulcer.
  • 10. Duodenal Ulcer • Duodenal sites are common as gastric sites • Most common in middle age • Male to female ratio—4:1 • Associated with increased serum pepsinogen • H. pylori infection common up to 95% • Smoking is twice as common
  • 11. Helicobacter Pylori (H. pylori) • Helicobacter Pylori (H. pylori) is a spiral shaped bacterium found in the stomach. • H. pylori damages stomach and duodenal tissue • Causes 80% of peptic ulcers • Survives the acid environment by attaching to the sugar molecules that line the stomach wall • Uses the mucus layer as protection
  • 12. Zollinger-Ellison Syndrome • Zollinger-Ellison Syndrome is a rare disorder that causes one or more tumors to form in the pancreas or • upper part of the small intestine called the duodenum. • The tumorsare called gastrinomas, and they secrete a large amountof the hormone gastrin. • In this syndrome increased levels of the hormone gastrin are produced, causing the stomach to produce excess
  • 13. Release of Gastric Acid • Histamine stimulates acid release by interacting with the histamine receptor • Acetylcholine activates the cholinergic receptors • Gastrin is released when food is present in the stomach
  • 14. Proton Pump Inhibitor Mode of Action Proton pump inhibitor that suppresses gastric acid secretion by specific inhibition of the H+/K+-ATPase in the gastric parietal cell. Blocks the enzyme in the wall of the stomach that produces acid.
  • 15. Antacids • Quick but short term • Buffer gastric acid, increasing the pH • Neutralize acid by the following reaction NaHCO3 + HCl NaCl + H2O + CO2
  • 16. Dosage Schedule Indication Dose Frequency Short-Term Treatment of Active Duodenal Ulcer 20mg Once daily for 4 weeks Benign Gastric Ulcer 40mg Once daily for 4-8 weeks Gastroesophageal Reflux Disease (GERD) Symptomatic GERD (with no esophageal erosions) 20mg Once daily for up to 4 weeks Erosive Esophagitis 20mg Once daily for 4-8 weeks Maintenance of Healing of Erosive Esophagitis 20mg Once daily
