GI cocktail

Last updated

A gastrointestinal cocktail, (also known as a GI cocktail or gastric cocktail), is a mixture of medications used to treat symptoms of dyspepsia. [1] The GI cocktail generally contains a mixture of viscous lidocaine, an antacid, and an anticholinergic. [1] [2] The GI cocktail is commonly prescribed in the hospital or emergency department, and has been used to help distinguish chest pain as either gastrointestinal or cardiac. [1] While it has been widely used in the treatment of dyspepsia, studies have suggested that the GI cocktail is only as effective as antacids alone. [1]

Contents

The "GI cocktail" does not refer to a specific product. Rather, it refers to a mixture of viscous lidocaine, an antacid, and an anticholinergic. [1] [2] Viscous lidocaine works as an anesthetic to numb pain in the throat, esophagus, and stomach. Antacids work to neutralize stomach acid. Anticholinergics work to ease symptoms that accompany dyspepsia including nausea, vomiting, and abdominal cramping.

Contents and dosing

The GI cocktail is a mixture of a viscous anesthetic, an antacid, and an anticholinergic. [1] [2] Common viscous anesthetics use are viscous lidocaine or xylocaine. Common antacids used are magnesium hydroxide, aluminum hydroxide, or simethicone (more commonly known as Mylanta or Maalox). [3] Common anticholinergics used are hyoscyamine sulfate, atropine sulfat e, scopolamine hydrobromide, and phenobarbital (more commonly known as Donnatal). [3] Typical dosing is 5ml of viscous anesthetic, 30ml of liquid antacid, and 10ml of anticholinergic. [3]

Medical uses

The GI cocktail is commonly prescribed in the hospital or emergency department to treat symptoms of dyspepsia. [4] These symptoms include: belching, heartburn, chest pain, abdominal discomfort, abdominal bloating, nausea, loss of appetite, and flatulence. Dyspepsia itself is not an illness, rather it is an indicator of chronic underlying gastrointestinal issues such as peptic ulcer disease, gastro-esophageal reflux disease, h.pylori gastritis, gastroparesis, or upper gastrointestinal cancers. [5] [6] Dyspepsia can additionally be contributed to medications such as potassium supplements, NSAIDs, digitalis, iron, glucocorticoids, and colchicine, as well as lifestyle factors such as diet, stress, and cigarette smoking. [5] [6]

Side effects

Some people experience side effects that are the result of the individual medications used to make the GI cocktail. They include:

Viscous lidocaine: [7]

Antacid: [8]

Anticholinergic: [9]

Efficacy

Prior studies regarding the GI cocktail for management of dyspepsia in the emergency department have varied in quality of methodology and have demonstrated mixed results. A 1990 single-blind study performed by Welling and Watson [4] compared 30 mL of antacid with or without the addition of 15 mL of viscous lidocaine and concluded that the addition of viscous lidocaine provided a significantly greater degree of immediate pain relief than antacids alone in patients with dyspepsia. A 2004 single-blind study performed by Vike and Davis, [7] compared treatment with antacids plus either viscous lidocaine or benzocaine solution and did not find a statistically significant difference between the two treatment arms – however the study lacked an antacid monotherapy arm. A robust double-blind clinical trial performed in 2003 by Berman et al. [1] compared 30 mL of antacid monotherapy, antacid with the addition of 10 ml of an anticholinergic, and an antacid with anticholinergic with the addition of 10 mL of 2% viscous lidocaine. That study demonstrated no statistically significant difference in pain relief between treatment arms and concluded that all treatments were clinically effective. The ultimately recommended antacid monotherapy alone in the treatment of dyspepsia.

An antacid is a substance which neutralizes stomach acidity and is used to relieve heartburn, indigestion, or an upset stomach. Some antacids have been used in the treatment of constipation and diarrhea. Marketed antacids contain salts of aluminum, calcium, magnesium, or sodium. Some preparations contain a combination of two salts, such as magnesium carbonate and aluminum hydroxide.

<span class="mw-page-title-main">Local anesthetic</span> Medications to reversibly block pain

A local anesthetic (LA) is a medication that causes absence of all sensation in a specific body part without loss of consciousness, providing local anesthesia, as opposed to a general anesthetic, which eliminates all sensation in the entire body and causes unconsciousness. Local anesthetics are most commonly used to eliminate pain during or after surgery. When it is used on specific nerve pathways, paralysis also can be induced.

Heartburn, also known as pyrosis, cardialgia or acid indigestion, is a burning sensation in the central chest or upper central abdomen. Heartburn is usually due to regurgitation of gastric acid into the esophagus. It is the major symptom of gastroesophageal reflux disease (GERD).

<span class="mw-page-title-main">Lidocaine</span> Local anesthetic

Lidocaine, also known as lignocaine and sold under the brand name Xylocaine among others, is a local anesthetic of the amino amide type. It is also used to treat ventricular tachycardia. When used for local anaesthesia or in nerve blocks, lidocaine typically begins working within several minutes and lasts for half an hour to three hours. Lidocaine mixtures may also be applied directly to the skin or mucous membranes to numb the area. It is often used mixed with a small amount of adrenaline (epinephrine) to prolong its local effects and to decrease bleeding.

Functional abdominal pain syndrome (FAPS), chronic functional abdominal pain (CFAP), or centrally mediated abdominal pain syndrome (CMAP) is a pain syndrome of the abdomen, that has been present for at least six months, is not well connected to gastrointestinal function, and is accompanied by some loss of everyday activities. The discomfort is persistent, near-constant, or regularly reoccurring. The absence of symptom association with food intake or defecation distinguishes functional abdominal pain syndrome from other functional gastrointestinal illnesses, such as irritable bowel syndrome (IBS) and functional dyspepsia.

Abdominal pain, also known as a stomach ache, is a symptom associated with both non-serious and serious medical issues.

Abdominal epilepsy is a rare condition most frequently found in children, consisting of gastrointestinal disturbances caused by epileptiform seizure activity. Though a few cases of it have been reported in adults too. It has been described as a type of temporal lobe epilepsy. Responsiveness to anticonvulsants can aid in the diagnosis. Distinguishing features of abdominal epilepsy include (1) Abnormal laboratory, radiographic, and endoscopic findings revealing paroxysmal GI manifestations of unknown origin (2) CNS symptoms (3) Abnormal EEG. Most published medical literature dealing with abdominal epilepsy is in the form of individual case reports. A 2005 review article found a total of 36 cases described in the medical literature.
