Generic Domperidone

Introduction

Domperidone is a medication primarily used to treat nausea and vomiting. As a generic medication containing the active compound domperidone, it works by increasing the movement or speed of the stomach and bowel, helping food pass through the stomach more quickly. It is available in 10mg pill form. While its main indications are related to gastrointestinal motility, it has also been explored for certain other associated conditions.

What is Domperidone?

Domperidone is a medication belonging to a class of drugs known as dopamine receptor antagonists. It acts peripherally, meaning it predominantly affects the gastrointestinal tract and does not significantly cross the blood-brain barrier. This characteristic helps to limit central nervous system side effects. Domperidone is the generic version of medications containing the active compound domperidone, often marketed under brand names such as Motilium. As a generic formulation, it offers a bioequivalent alternative to branded versions, providing comparable therapeutic effects at a potentially lower cost.

How Domperidone Works

Domperidone functions by blocking dopamine D2 receptors in specific areas of the body. In the chemoreceptor trigger zone (CTZ), which is located outside the blood-brain barrier, dopamine typically promotes nausea and vomiting. By blocking these receptors, domperidone reduces the signals that lead to these symptoms. Furthermore, domperidone enhances gastrointestinal motility by counteracting the effects of dopamine in the gut. Dopamine normally slows down the stomach and intestinal movements. Domperidone inhibits this effect, promoting faster stomach emptying and increasing the coordinated contractions of the stomach and intestines. This action helps to alleviate symptoms like bloating, heartburn, and a feeling of fullness. The onset of action typically begins within 30 to 60 minutes of taking the medication.

Conditions Treated with Domperidone

Domperidone is approved for the symptomatic treatment of the following conditions:

• Nausea and Vomiting: This is the primary indication for domperidone. By acting on the CTZ and enhancing gastric emptying, it effectively reduces feelings of sickness and the act of vomiting, providing relief from acute episodes.
• Gastroparesis: This condition, often associated with diabetes, involves delayed emptying of the stomach. Domperidone's prokinetic effect helps to accelerate gastric transit, reducing symptoms like early satiety, bloating, and nausea that are characteristic of gastroparesis.
• Bloating and Early Satiety: By promoting faster stomach emptying and reducing the residence time of food in the stomach, domperidone can alleviate the uncomfortable sensation of bloating and the feeling of being full too quickly after starting a meal.
• Heartburn: Persistent heartburn can sometimes be exacerbated by slow gastric emptying or reflux of stomach contents. Domperidone's ability to speed up stomach emptying can help reduce the likelihood of reflux occurring, thereby alleviating heartburn symptoms.
• Gastro-oesophageal Reflux Disease (GORD): While not a primary treatment for the underlying cause of GORD, domperidone can be used adjunctively to manage associated symptoms. By improving gastric motility and facilitating faster clearance of the stomach, it may help reduce the frequency and severity of reflux episodes and associated discomfort.

Is Domperidone the Right Medication for You?

Domperidone is generally considered for adults experiencing persistent or recurrent symptoms of nausea, vomiting, bloating, heartburn, or those diagnosed with gastroparesis. It is particularly beneficial for individuals whose symptoms are linked to a delay in gastric emptying or gastrointestinal motility issues. Patients who have found limited relief with other treatments for these symptoms may find domperidone effective.

However, domperidone is not suitable for everyone. It is contraindicated in individuals with known hypersensitivity to the active substance or any of its excipients. Due to potential cardiac risks, it should be avoided in patients with certain pre-existing heart conditions, including QT prolongation, congestive heart failure, or those taking medications known to prolong the QT interval. It is also not recommended for individuals with severe liver impairment or moderate to severe kidney problems. Patients experiencing bleeding from the gastrointestinal tract or signs of intestinal obstruction should not take domperidone. A thorough discussion with a healthcare provider is essential to determine if domperidone is appropriate based on an individual's complete medical history and current health status.

Safety Information

⚠️ Who Should Not Take Domperidone

Domperidone is contraindicated in individuals with the following conditions:

• Known hypersensitivity or allergy to domperidone or any inactive ingredients in the formulation.
• Prolactinoma, a type of tumour that releases prolactin.
• Conditions that may cause gastrointestinal bleeding.
• Mechanical intestinal obstruction or perforation.
• Moderate to severe liver impairment.
• Congenital or acquired QT prolongation.
• Significant cardiac arrhythmias or conduction disturbances (e.g., heart block).
• Use with other medications that are known to prolong the QT interval or are potent CYP3A4 inhibitors.

Common Side Effects

The following side effects are generally mild and transient:

• Dry mouth
• Headache
• Dizziness
• Abdominal cramps or pain
• Diarrhoea
• Sore breasts or increased milk production (galactorrhoea).
• Skin rash

If any of these persist or become bothersome, it is advisable to consult a healthcare professional.

Serious Side Effects (Seek Immediate Medical Help)

Although rare, serious side effects can occur:

• Cardiac Issues: Irregular heartbeat (QT prolongation, Torsades de Pointes), leading to fainting or palpitations.
• Allergic Reactions: Swelling of the face, lips, tongue, or throat, difficulty breathing, severe dizziness, or skin rash.
• Neurological Effects: Seizures, uncontrolled movements (e.g., tremors, muscle stiffness), excessive sleepiness.
• Gastrointestinal Bleeding: Signs include black, tarry stools or vomiting blood.

If you experience any of these serious side effects, stop taking domperidone and seek immediate medical attention.

Drug & Food Interactions

Domperidone can interact with several medications. It is crucial to inform your doctor or pharmacist about all medications you are taking, including:

• Potent CYP3A4 Inhibitors: Medications such as ketoconazole, itraconazole, ritonavir, and clarithromycin can significantly increase domperidone levels in the blood, raising the risk of side effects, particularly cardiac events.
• QT-Prolonging Drugs: Concomitant use with antiarrhythmics (e.g., amiodarone, sotalol), certain antibiotics (e.g., erythromycin), antipsychotics (e.g., pimozide), and antidepressants (e.g., citalopram) can further increase the risk of QT prolongation.
• Antacids and Antisecretory Agents: Taking these medications at the same time as domperidone may reduce its effectiveness by increasing stomach pH. It is recommended to take domperidone at least 1 to 2 hours before or after these agents.
• Grapefruit Juice: While not as potent as CYP3A4 inhibitors, grapefruit juice can also inhibit the CYP3A4 enzyme pathway and may increase domperidone blood levels. It is advisable to limit consumption while taking domperidone.

Off-Label and Investigational Uses of Domperidone

While domperidone's primary approved uses are focused on nausea, vomiting, and general gastrointestinal motility, clinical studies and some healthcare providers have explored its use in other associated conditions, though these are not formally approved by regulatory bodies.

• Post-operative Nausea and Vomiting (PONV): Domperidone has been investigated as a prophylactic or rescue agent for nausea and vomiting following surgical procedures and anaesthesia. Its mechanism of action makes it a candidate for managing these common post-operative complications.
• Migraine-Associated Nausea: Some research suggests that domperidone, when used in conjunction with standard migraine treatments, may help alleviate the nausea and vomiting that often accompany migraine headaches, improving patient comfort and potentially aiding oral medication absorption.
• Functional Dyspepsia: Beyond gastroparesis, domperidone is sometimes considered for broader symptoms of functional dyspepsia, such as postprandial fullness, belching, and upper abdominal pain, when other treatment options have been inadequate.

It is crucial to note that the efficacy and safety profile of domperidone for these off-label applications have not undergone the same rigorous evaluation and regulatory approval as its primary indications. Any use of domperidone for conditions not officially approved should only be undertaken under the strict supervision and guidance of a qualified healthcare professional.

Storage & Handling

Domperidone pills should be stored at room temperature, typically between 20°C to 25°C (68°F to 77°F). protect them from excessive heat, light, and moisture. Avoid storing them in the bathroom or kitchen, where humidity levels can be high. Keep the medication in its original container. Ensure the container is tightly closed when not in use.

Expired medication should not be used. Dispose of any unused or expired domperidone safely, preferably by returning it to a local pharmacy for proper disposal. Do not flush medication down the toilet or pour it into a drain unless specifically instructed to do so.
