Metoclopramide: Laxative Or Not?

Metoclopramide is a medication used to treat certain conditions of the stomach and intestines. It is a substituted benzamide that promotes gastric motility and reduces the emetic activity of chemotherapy agents by blocking dopamine receptors and 5-HT3 receptors in the chemoreceptor trigger zone. Metoclopramide is used as a short-term treatment for ongoing heartburn when other medicines do not work well enough. It is also used to treat gastroparesis in diabetic patients, reducing symptoms of nausea, vomiting, and stomach/abdominal fullness. The medication is not recommended for children due to an increased risk of serious side effects such as muscle spasms and uncontrolled muscle movements.

Metoclopramide is used to treat heartburn

Metoclopramide is a prescription medicine used to treat heartburn symptoms caused by gastroesophageal reflux disease (GERD) when other treatments have not worked. GERD occurs when acid flows up from the stomach, causing heartburn and potentially damaging the oesophagus (the tube that connects the mouth to the stomach). Metoclopramide is used to help relieve heartburn and heal sores in the oesophagus.

Metoclopramide is a "prokinetic" drug that stimulates the muscles of the gastrointestinal tract, including the muscles of the lower oesophageal sphincter, stomach, and small intestine. By interacting with receptors for acetylcholine and dopamine, it strengthens the muscle of the lower oesophageal sphincter, decreasing the reflux of stomach acid. It also stimulates the muscles of the stomach, hastening the emptying of solid and liquid meals into the intestines. This speeds up the movement of food through the stomach and intestines and prevents reflux.

Metoclopramide is typically used as a short-term treatment for ongoing heartburn, usually lasting between 4 to 12 weeks. It is taken orally, up to four times daily, 30 minutes before meals and at bedtime. It is important to note that metoclopramide may cause serious side effects, including muscle spasms, depression, and a rare nervous system disorder called neuroleptic malignant syndrome (NMS). Therefore, it is crucial to consult a doctor or pharmacist for guidance on the use of this medication.

It is also used to treat gastroparesis in diabetic patients

Metoclopramide is used to treat gastroparesis in diabetic patients. Gastroparesis is a chronic disorder characterised by impaired gastric emptying and altered motility in the upper GI tract. It is estimated to affect approximately 5 million people in the USA and is most often seen in young individuals, with a mean age of onset of 34 years. Diabetes mellitus is a risk factor for the development of gastroparesis, which is frequently seen in diabetics. Metoclopramide is the only US FDA-approved medication for the treatment of gastroparesis. It works by blocking dopamine, a natural substance, and speeding up stomach emptying and movement of the upper intestines.

Metoclopramide is used as a short-term treatment for gastroparesis in diabetic patients, usually for 2 to 8 weeks until the gut is working well. The medication is taken orally, with a dose of 5-10 mg, 30 minutes before meals and at bedtime. The dose can be increased to up to 20 mg four times a day if necessary, but this may be limited by side effects. It is important to note that metoclopramide has been associated with an increased risk of serious side effects in children and older adults, and it is not recommended for use in children.

Metoclopramide has been shown to be effective for the short-term treatment of gastroparesis, but long-term efficacy has not been proven. Additionally, the FDA has issued a black-box warning regarding the long-term usage of metoclopramide due to the potential risk of tardive dyskinesia, a serious movement disorder. This warning highlights the potential irreversible nature of tardive dyskinesia, which can occur with chronic use of metoclopramide for at least 3 months.

In summary, metoclopramide is a valuable medication for treating gastroparesis in diabetic patients, but its use should be carefully monitored due to potential side effects, especially with long-term use.

It blocks dopamine receptors

Metoclopramide is a substituted benzamide that promotes gastric motility and reduces the emetic activity of chemotherapy agents by blocking dopamine receptors at low-to-moderate doses. It is a dopamine-receptor blocking agent that is used in the treatment and prevention of nausea and vomiting. It is also used to treat certain conditions of the stomach and intestines.

Metoclopramide is a powerful antiemetic because of its combined actions on the chemoreceptor trigger zone and intestinal motility. It blocks a natural substance, dopamine, and speeds up stomach emptying and movement of the upper intestines. It is used as a short-term treatment for ongoing heartburn when usual medicines do not work well enough. It is also used in diabetic patients who have poor emptying of their stomachs (gastroparesis).

Metoclopramide is a dopamine-receptor blocking agent with both peripheral (mainly in the stomach) and central nervous system (CNS) actions. It is a dopamine type 2 receptor antagonist. It is a robust D2 receptor antagonist and also a mixed 5-HT3 receptor antagonist/5-HT4 receptor agonist. It is also an antagonist at 5HT3 (type 3 serotonin receptors) and an agonist at 5HT4 receptors. It blocks the antiperistaltic effects of apomorphine, allowing it to slow apomorphine's inhibition of gastric emptying, thereby accelerating gastric emptying by increasing the amplitude and duration of esophageal contractions.

Metoclopramide is generally not intended for long-term use. The oral preparations are recommended for four to 12 weeks of therapy. Use of parenteral metoclopramide should be limited to one or two days. The most common adverse reactions are restlessness, drowsiness, fatigue, and lassitude. Extrapyramidal symptoms occur rarely and only with high dosage or prolonged use.

It is not recommended for children

Metoclopramide is a drug used to treat certain conditions of the stomach and intestines. It is used as a short-term treatment for ongoing heartburn when usual medications do not work well enough. It is also used to treat gastroparesis in diabetic patients, reducing symptoms of nausea, vomiting, and stomach/abdominal fullness.

While metoclopramide can be used by most adults and children aged one and over, it is not recommended for children due to an increased risk of serious side effects. Children may be more sensitive to the side effects of the drug, especially muscle spasms and uncontrolled muscle movements. The drug regulatory agencies of Canada and the EU have revised the labelling of metoclopramide to contraindicate its use in children under one year of age and to caution against its use in children under five years of age and its duration of use beyond five days.

The most common adverse effects reported in prospective studies of metoclopramide in children were extrapyramidal symptoms (EPS), diarrhea, and sedation. While these effects were reversible and of no long-term significance, more serious side effects such as dysrhythmia, respiratory distress/arrest, neuroleptic malignant syndrome, and tardive dyskinesia were also rarely associated with metoclopramide use in children.

Extrapyramidal disorders may occur, particularly in children and young adults, and/or when high doses are used. These reactions usually occur at the beginning of the treatment and can occur after a single administration. Metoclopramide should be discontinued immediately if extrapyramidal symptoms occur. These effects are generally completely reversible after treatment discontinuation but may require symptomatic treatment.

In conclusion, while metoclopramide can be beneficial for treating certain conditions of the stomach and intestines in adults, it is not recommended for children due to the increased risk of serious side effects, including muscle spasms, uncontrolled muscle movements, and extrapyramidal disorders. The potential benefits of using metoclopramide in children must be carefully weighed against the risks of adverse effects, and alternative treatments should be considered whenever possible.

It can cause drowsiness and dizziness

Metoclopramide is a prescription drug used to treat certain conditions of the stomach and intestines. It is a short-term treatment for ongoing heartburn when the usual medicines do not work well enough. It is also used to treat gastroparesis in diabetic patients, reducing symptoms of nausea, vomiting, and stomach/abdominal fullness.

Metoclopramide can cause drowsiness and dizziness, which are common side effects of the medication. These side effects can impact a person's ability to perform certain tasks and should be carefully considered.

Drowsiness

Metoclopramide can cause drowsiness, with up to 70% of people experiencing this side effect. It is important for patients taking metoclopramide to refrain from driving, operating machinery, or engaging in activities that require alertness until they know how the medication affects them. Alcohol or marijuana can enhance drowsiness, so patients should avoid these substances or consult their doctor if they are using them.

Energy Levels and Fatigue

Metoclopramide may also cause a lack of energy and fatigue, which can be related to drowsiness. Patients should be cautious about operating vehicles or machinery and refrain from consuming alcohol, as it will make them feel more tired. If these symptoms persist or worsen, it is important to consult a doctor.

Dizziness

Dizziness is another common side effect of metoclopramide, affecting 1% to 10% of people. If dizziness occurs, patients should stop their current activity and sit or lie down until they feel better. As with drowsiness, activities that require alertness should be avoided, and alcohol consumption should be limited as it can worsen dizziness. Staying hydrated by drinking plenty of fluids can also help alleviate dizziness.

Dehydration

Dehydration can be a concern for people experiencing dizziness, as it may be a sign of dehydration. It is important to drink enough water or other fluids to maintain hydration and prevent dehydration-related complications.

In summary, metoclopramide can cause drowsiness and dizziness in a significant number of people. These side effects can impact daily activities and may require adjustments or alternative treatments. It is crucial to follow the advice of a doctor or pharmacist when taking metoclopramide and to report any persistent or worsening side effects.
