The Gastric Defenders

Antacids + Gastric Medications (Ranitidine, Omeprazole, Sucralfate, Aluminum Hydroxide)

Welcome to the Digestive System—where acid isn’t just “strong”… it’s an unstoppable force that can either help digestion or destroy the lining if the defenses fail.

In this Pharmacology MANGA volume, Lucy and the crew enter the “Acid Kingdom” (stomach + duodenum territory) to stop ulcer damage, calm reflux chaos, and rebuild the mucosal barrier—using the exact GI meds you’ll see in real clinical practice.

What this book covers (in story form):

Acid Reducers

• Ranitidine (Zantac) — How histamine signaling ramps up acid production, and how blocking H2 receptors lowers acid output.

• Omeprazole (Prilosec) — The “final boss switch” on acid: proton pump shutdown, when it works best, and why long-term monitoring matters.

Mucosal Protectants

• Sucralfate (Carafate) — A protective “bandage” over ulcers: how it coats damaged tissue, when to give it, and why timing with other meds is everything.

Antacids

• Aluminum Hydroxide (Amphojel) — Fast symptom relief by neutralizing acid, plus the nursing watch-outs that show up on exams and at the bedside.

You’ll learn through:

• MOA explained with simple physiology (acid production → mucosal injury → med action)

• Indications you actually see (GERD, gastritis, PUD, stress ulcer risk)

• Side effects linked to body function (not just memorized lists)

• Nursing considerations that prevent complications

  • medication timing & spacing

  • symptom red flags (GI bleed, worsening pain, weight loss)

  • monitoring patterns and patient teaching that saves repeat ER visits

• Quick-recall panels + mini “test-your-brain” moments built into the story
