Study Notes

Gastrointestinal (GI) Pharmacology

GI pharmacology involves the actions of drugs affecting GI system function.
These drugs normalize impaired function in the GI tract.
The GI tract is the pathway of the digestive system, from the mouth to the anus (oral cavity, pharynx, esophagus, stomach, small intestine, large intestine, and anal canal).

GI Picture

A diagram shows the parts of the digestive system including the mouth, esophagus, stomach, small intestine (duodenum, jejunum, ileum), large intestine (colon), rectum, anus, liver, gallbladder, and pancreas.
The diagram visually represents the location of these organs within the body.
The cececum and ileocecal valve are labeled.

Gastroesophageal Reflux Disease (GERD)

GERD is the flow back or return of stomach contents into the esophagus, causing symptoms or mucosal damage.
Gastroesophageal reflux is when stomach contents return to the esophagus.
A classic symptom is frequent and persistent heartburn.

Normal Physiology Functions (Esophagus)

The esophagus transports food from the mouth to the stomach through peristaltic contractions.
The lower esophageal sphincter (LES) relaxes during swallowing to allow food into the stomach and then contracts to prevent reflux.

Pathogenesis of GERD

Three lines of defense must be impaired for GERD to develop.
These defenses can be compromised due to:
LES barrier impairment
Relaxation of LES
Low resting LES pressure
Increased gastric pressure
Decreased clearance of refluxed materials
Decreased esophageal mucosal resistance

Contributing Factors

Factors that decrease LES pressure, irritate the gastric mucosa, or stimulate acid secretions:
Chocolate, alcohol, fatty meals, coffee, cola, tea, garlic, onions, smoking
Tomato-based products, coffee, spicy foods, citrus juices, NSAIDs, aspirin, iron, potassium chloride, alendronate
Soda, beer, smoking

Lines of Defense

Refuxed materials are cleared from the esophagus through:
Primary peristalsis triggered by swallowing (increasing salivary flow)
Secondary peristalsis from esophageal distension
Gravitational effects
Esophageal mucosal resistance (including mucus production and bicarbonate movement from blood to mucosa)

Factors Affecting Esophageal Damage

Esophageal damage depends on:
The composition of refluxed material (acid vs. alkaline)
The volume of refluxed material
The length of contact time of reflux material
The natural sensitivity of the esophageal mucosa
The rate of gastric emptying

Typical Symptoms

Common symptoms appear when pH is less than 4:
Heartburn, belching, regurgitation, hypersalivation
These symptoms may be exacerbated by eating or reclining.

Atypical Symptoms

Atypical symptoms of GERD can include:
Chronic cough, hoarseness, chest pain (mimicking angina)
These symptoms may be the only indication of GERD.

Complications

Potential complications of GERD include:
Esophagitis
Esophageal strictures and ulcers
Hemorrhage
Perforation
Aspiration
Precipitation of an asthma attack

Warning Signs

Conditions that merit endoscopic evaluation include:
Dysphagia
Odynophagia
Bleeding
Unplained weight loss
Choking
Chest pain

Diagnosis

GERD diagnosis involves a review of clinical symptoms and history.
Presenting symptoms and associated risk factors are considered.
Empiric therapy and evaluation of improvement are common diagnostic pathways.
Endoscopy is used if warning signs are present.

When to Refer for Further Care

Conditions requiring referral for additional care include:
Chest pain
Heartburn while taking proton pump inhibitors (PPIs)
Heartburn that persists after 2 weeks of treatment
Nocturnal heartburn symptoms
Frequent heartburn lasting 3 or more months
GI bleeding or other warning signs
Concurrent use of nonsteroidal anti-inflammatory drugs (NSAIDs)
Pregnancy or breastfeeding
Children under 12 years old

Therapy Goals

Therapy aims to:
Alleviate or eliminate symptoms
Reduce the frequency and duration of esophageal reflux
Promote healing in injured mucosa
Prevent complications

Therapy

Treatment strategies address:
Increasing lower esophageal sphincter (LES) pressure
Enhancing esophageal acid clearance
Improving gastric emptying
Protecting esophageal mucosa
Decreasing the acidity of reflux
Decreasing gastric volume available for reflux

Treatment Phases

GERD treatment is categorized into three phases:
Phase 1: Lifestyle changes (2 weeks) include lifestyle modifications and patient-directed therapy with over-the-counter (OTC) medications.
Phase 2: Pharmacologic intervention, with standard/high-dose antisecretory therapy
Phase 3: Surgical intervention for patients who don't respond to pharmacologic therapy, or have severe complications

Treatment Selection

Mild intermittent heartburn is treated with lifestyle changes and antacids.
Symptomatic relief for mild to moderate GERD uses lifestyle changes and proton-pump inhibitors (PPIs) for 4-8 weeks.
For healing erosive esophagitis or moderate to severe GERD, lifestyle changes plus PPIs for 8-16 weeks.
PPIs are preferred for their rapid symptom relief and healing rate.
Prokinetic agents may also be considered in selected patients.

Examples of Prokinetic Agents

Metoclopramide
Domperidone

Lifestyle Modifications

Elevating the head of the bed, decreasing fat intake, quitting smoking, avoiding recumbency after meals, achieving weight loss, limiting alcohol intake, loose-fitting clothing, and avoidance of aggravating foods are lifestyle strategies.

Drug Therapy - Antacids

Antacids: reduce gastric acid, frequently containing magnesium salts, aluminium salts, or calcium carbonate and sodium bicarbonate.
They increase LES pressure and do not promote esophageal healing.

Drug Therapy - PPIs

Proton pump inhibitors (PPIs) are used to treat moderate-to-severe GERD.
Omeprazole, esomeprazole, lansoprazole, pantoprazole, and rabeprazole are examples.

Drug Therapy - Prokinetiacs

Prokinetic agents enhance smooth muscle motility from the esophagus to the proximal small bowel, accelerating gastric emptying and intestinal transit.
Metoclopramide is an example.

Special Populations (Pregnancy)

GERD is common in pregnancy due to decreased LES pressure and increased abdominal pressure.
Antacids are generally safe but avoid chronic high doses.

Counseling Questions

Key questions to consider before recommending a treatment include:
Duration and frequency of symptoms
Quality and timing of symptoms
Alcohol and tobacco use
Dietary choices
Medications already tried
Presence of other diseases or medications

Case Study

A 45-year-old male postal worker, with occasional heartburn after meals, and limited success with Tums, seeks further treatment options.
The case study involves questions about additional questions to ask the patient, reasons to refer him to a physician, the patient's GERD type, and recommended treatment options.
