Esomeprazole is effective for treating peptic ulcer disease and preventing rebleeding from ulcers. It works by irreversibly blocking the proton pump in the stomach, strongly inhibiting acid production. This allows platelet aggregation and clot stabilization at a gastric pH above 6. Esomeprazole maintains inhibitory effects on acid for a longer period than other PPIs, significantly reducing rebleeding rates following ulcer treatment. As a result, esomeprazole is recommended for treating bleeding ulcers and preventing their recurrence.

Peptic Ulcer Disease

3. The Stomach Functions & Glands
 Acts as storage tank for food
Breaking down the food into a liquidly mixture called chyme
Mixing enzymes which is are chemicals that break down food.
Delivers chyme to the small intestine
Glands:
Cardiac
Pyloric
Gastric  contain parietal cells that produce and secret HCL (primary site of action for
many acid controller drugs.

4. Parietal cells
Parietal cells, are the stomach epithelium cells that secrete gastric acid
The parietal cell contains receptor for gastrin histamine (H2) & acethylcholine (M3)
When acetylcholine, histamine or gastrin (released from G cells into the blood) bind to the
parietal cell receptors, that stimulate acid secretion from a H+,K+ ATPase (the proton
pump) on the canalicular surface.
Olbe, L., Carlsson, E., & Lindberg, P. (2003).Nature Reviews Drug Discovery, 2, 132-139.

5. Parietal Cells
Gastric acid is secreted by parietal cells of
the stomach in response to stimuli such as
the presence of food in the stomach or
intestine and the taste, smell, sight or
thought of food. Such stimuli result in the
activation of histamine, acetylcholine or
gastrin receptors (the H2, M3 and CCK2
receptors, respectively) located in the
basolateral membrane of the parietal cell,
which initiates signal transduction
pathways that converge on the activation
of the H+K+-ATPase the final step of acid
secretion.
Inhibition of this proton pump has the
advantage that it will reduce acid secretion
independently of how secretion is
stimulated, in contrast to other
pharmacological approaches to the
regulation of acid secretion; for example,
the inhibition of acid secretion by H2
receptor antagonists can be overcome by
food-induced stimulation of acid secretion
via gastrin or acetylcholine receptors.
Olbe, L., Carlsson, E., & Lindberg, P. (2003).Nature Reviews Drug Discovery, 2, 132-139.

6. Acid Controlling Agents – Proton Pump
Inhibitors
Mechanism of Action: Irreversibly bind to H+/K+ ATPase enzyme
Result: ALL gastric acid secretion is blocked
Proton Pump Inhibitors:
Esomeperazole  works by binding irreversibly to the H+/K+ ATPase in the proton pump.
Because the proton pump is the final pathway for secretion of hydrochloric acid by the parietal
cells in the stomach, its inhibition dramatically decreases the secretion of hydrochloric acid into
the stomach and alters gastric pH. This is the same mechanism of action as omeprazole and
the other PPIs.
Lansoprazole
Omeprazole
Pantoprazole
Rabeprazole
Olbe, L., Carlsson, E., & Lindberg, P. (2003).Nature Reviews Drug Discovery, 2, 132-139.

7. ROLE OF PPI AS ACID SUPPRESSION
AGENT
• Pharmacological agents that suppress acid secretion are widely considered
the standard of care for the prevention of ulcer re-bleeding after initial
endoscopic hemostasis in ulcer with high risk stigmata (those with active
bleeding, non bleeding visible vessel and possibly adherent clot)1-5
• The therapeutic goal in these patients is to achieve an intragastric
pH>6, a point at which the clotting process is optimized and any
formed clot is stabilized

9. Peptic Ulcer
Peptic ulcers are open sores that develop in the inner lining of the stomach and the upper part of the small
intestine. The most common symptom of peptic ulcers is abdominal pain.
 Peptic ulcers include:
Stomach ulcers that occur in the stomach
Duodenal ulcers that occur in the duodenum (duodenum)

10. CAL

11. Symptoms of Peptic Ulcer
Pain in the stomach. This pain arises due to irritation of the stomach acid that wets the wound.
Usually, the pain appears at night and gets worse when the stomach is empty. In more severe
conditions, the pain felt can spread to the neck, navel, to the back.
 Indigestion.
Vomiting or vomiting blood — which may appear red or black Dark blood in the stool, or black or
mushy stools
Difficulty breathing, Feeling weak, Nausea or vomiting, Unexplained weight loss, Changes in
appetite

12. Cause
Helicobacter pylori infection
Use of non-steroidal anti-inflammatory drugs, such as ibuprofen, aspirin, or diclofenac.
Smoking and drinking habits.
Stress that is not immediately addressed.
Health problems, such as pancreatic tumors and radiation treatment to the stomach area.

13. Complications
◦ Bleeding in the stomach
◦ Perforation
◦ Peritonitis (inflammation of the thin lining of the inner wall of the
abdomen)
◦ Obstruction
◦ Stomach cancer.

NICE. Managing peptic ulcer disease on adults. 2021
Initial treatment, for people using NSAIDs with diagnosed peptic ulcer, stop the
use of NSAIDs where possible. Offer full-dose PPI or H2RA therapy for 8 weeks
and, if H. pylori is present, subsequently offer eradication therapy.
Esomeprazole is first choice to treat peptic ulcer caused by NSAID &
Helicobacter pylori infection.

26. Conclusion: Esomeprazole, given as a continuous high-
dose intravenous infusion followed by an oral regimen
after successful endoscopic therapy for Peptic Ulcer
Bleeding, was well tolerated, with no apparent safety
concerns from either the high-dose intravenous
treatment or oral phases.

27. •. 2015 Nov;32(11):1160-76.
Conclusion: In this phase 3, multicenter, randomized trial
conducted in China, esomeprazole showed a numerical
trend towards superior clinical benefit over cimetidine in the
prevention of rebleeding in patients who had successfully
undergone initial hemostatic therapy of a bleeding peptic
ulcer, with a similar safety and tolerability profile

28. Esomeprazole
• Esomeprazole is the S-isomer of omeprazole.it has a better
pharmacokinetic and pharmacodynamic profile than
omeprazole.1
• Pharmacodynamics: in an acidic environment, esomeprazole is
protonated and becomes the active form, then binds to the
sulfhydryl group in the proton pump of parietal cells and
inhibits gastric acid production.1
• Esomeprazole reduces acid secretion through inhibition of
the H+, K+-ATPase in gastric parietal cells. Esomeprazole acts as
an exosome inhibitor by blocking the exosome release via the
inhibition of V-H+-ATPases.2
• Esomeprazole increases gastric pH better than omeprazole,
lansoprazole, pantoprazole and rabeprazole.1

Gastric anti-secretory treatment when the oral route is not possible, such as:
Gastro esophageal reflux disease in patients with esophagitis and/or severe
