Reglan, Metoclopramide Injection


Reglan, which is also referred to as Metoclopramide Injection, is a medicinal substance that has a wide range of therapeutic uses. Utilizing these types of drugs plays a role in today's medical field, and both healthcare providers and patients must comprehensively understand their intricacies.

What is Reglan Metoclopramide

Reglan, also known as Metoclopramide is a medication used in the medical field to help manage conditions such as gastroesophageal reflux disease (GERD) and gastroparesis. It is quite effective, in reducing feelings of nausea and vomiting that can occur as effects of certain chemotherapy drugs or after undergoing surgery.


How It Works

Mechanism of action of Metoclopramide in the body

Metoclopramide works in ways mainly by blocking the dopamine D2 receptors. This action helps to reduce feelings of nausea and vomiting by inhibiting these receptors in the chemoreceptor trigger zone found in the central nervous system.

Additionally, it has some affinity for receptors that can increase the release of acetylcholine and may also have direct effects on the gastrointestinal tract through its muscle-relaxing properties.

How it affects gastrointestinal motility

When it comes to the movement of the system, Metoclopramide is known for its ability to speed up the emptying of the stomach and increase muscle tone in the lower esophageal sphincter. It does this by;

  1. Strengthening the strength of contractions in the stomach 
  2. Improving the regularity of contractions in the jejunum
  3. Speeding up how quickly the stomach empties, into the small intestine.

As a result, these effects help food move through the stomach faster, reducing the likelihood of reflux.

Dosage and Administration

Standard dosing guidelines

To achieve the results of your therapy, it is crucial to follow the recommended dosing guidelines. Usually, adults are advised to take 10mg to 15mg three to four times a day before meals and at bedtime. The specific dosage may differ depending on the condition and how the patient responds to the treatment.

Adjustments for specific patient populations

Some groups of patients may need adjustments in their medication dosage to achieve the results with minimal side effects.

  • For example, elderly patients or those with kidney problems might require a dose.
