Famotidine and Antacids for Treatment of Dyspepsia

June 1, 2026 updated by: Adam Singer, Stony Brook University

Comparing Intravenous Famotidine and Oral Antacids in the Treatment of Dyspepsia in the Emergency Department

The aim of this study is to compare intravenous famotidine, an H2 receptor antagonist, and Maalox/ Mylanta, an oral antacid, in treatment of dyspepsia in the emergency department. The goal of this study is to reduce patients' pain based on the verbal numerical pain scale. The anticipated outcome is for pain levels in both groups to decrease. It is expected that antacids will improve symptoms more quickly and to a greater degree within an hour of taking medication based on the results of similar studies.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study will be conducted in the Emergency Department at Stony Brook University Hospital. Investigators intend to enroll approximately 80 patients who present to the emergency department with dyspepsia symptoms. The patients will be randomized to one of two groups: one group will receive 20 mg of intravenous famotidine and the other will receive 30 ml of oral Maalox/ Mylanta. The verbal numeric pain score (VNP) will be used to measure pain at 0 minutes, 15 minutes, 30 minutes, 45 minutes, and 60 minutes after administration of the study drug. Pain severity assessments will be performed by an investigator blinded to study treatment. Data will also be collected regarding demographic, clinical information, patient satisfaction and the need for rescue medications in each of the two study groups at the end of the 60-minute study period. At the end of the study period, the patients may be treated with additional analgesia at the discretion of their ED provider.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Verbal Numerical Pain Score
Time Frame: at 1 hour
Patients will be asked to rate their pain on a scale of 0 to 10 with 0 indicating no pain and 10 indicating the worst pain imaginable every 15 minutes for 60 minutes.
at 1 hour

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Need for Rescue Medications
Time Frame: at 1 hour
Investigators will assess frequency of need for rescue medications between groups.
at 1 hour
Satisfaction with Assigned Medication
Time Frame: at 1 hour
Investigators will gather data regarding patient satisfaction with their assigned treatment using a 5 item likert scale from very dissatisfied (1), dissatisfied (2) neither satisfied nor dissatisfied (3), satisfied (4) and very satisfied (5). The outcome will be measured as the percentages of patients choosing very satisfied or satisfied with their assigned medications.
