Formula Information

A small arrow pointing down

Dextromethorphan Hydrobromide 120 mg Slow Release (MEM4) Oral Capsules are a sophisticated pharmaceutical formulation designed to provide patients with a consistent and prolonged therapeutic effect. The active ingredient, Dextromethorphan Hydrobromide, is a widely recognized antitussive agent used to suppress coughs. It operates by affecting the signals in the brain that trigger the cough reflex, thereby providing relief from nonproductive coughs often associated with common colds and other upper respiratory infections.

The innovative aspect of this formulation lies in the use of Methocel E4M, a high-viscosity grade of hydroxypropyl methylcellulose. This controlled-release polymer is instrumental in creating a matrix that encapsulates the active ingredient, allowing for a slow and steady release of Dextromethorphan Hydrobromide into the digestive system. By employing this technology, the capsules ensure a sustained release of the medication over an extended period, which can be particularly beneficial for patients requiring round-the-clock cough suppression. This can lead to a significant reduction in the dosing frequency, potentially enhancing patient compliance and convenience, especially for those who may have difficulty adhering to more frequent dosing schedules.

For prescribers, it is important to note that the slow-release mechanism of these capsules may alter the onset of action when compared to immediate-release formulations. As such, they are not intended for the relief of acute coughing spells but rather for the management of persistent coughs where steady plasma levels of the medication are desired. Additionally, the Methocel E4M polymer ensures that the release rate of Dextromethorphan is not significantly affected by pH changes throughout the gastrointestinal tract, providing a predictable pharmacokinetic profile.

Patients should be advised that the slow-release capsules must be swallowed whole and not crushed or chewed, as this could disrupt the controlled-release system and lead to the rapid release of the entire dose at once, increasing the risk of adverse effects. It is also important for patients to understand that while Dextromethorphan Hydrobromide can provide relief from cough, it does not treat the cause of the cough or speed recovery from the underlying condition.

As with any medication, potential side effects may include drowsiness, dizziness, nausea, and others, and patients should be counseled on what to expect and when to seek medical attention. Prescribers should consider the patient's overall medication regimen to avoid interactions, particularly with other central nervous system depressants and monoamine oxidase inhibitors (MAOIs).

Our team of compounding pharmacists is committed to providing the highest level of support and expertise to both patients and healthcare providers.

Drug Interactions

A small arrow pointing down

Dextromethorphan hydrobromide is a cough suppressant that acts on the cough center in the brain to provide relief from persistent coughing. When formulated as a slow-release capsule with Methocel E4M, it is intended to provide a steady release of the medication over an extended period, which can be particularly beneficial for managing symptoms during both daytime and nighttime, potentially improving sleep and daily functioning. However, it is important to be aware of potential drug interactions when taking this medication.

One significant interaction is with monoamine oxidase inhibitors (MAOIs), which are used to treat depression and other psychiatric conditions. Patients taking MAOIs or who have taken them within the past 14 days should not use dextromethorphan, as this combination can lead to serious side effects, including serotonin syndrome, which is characterized by symptoms such as confusion, hallucination, seizure, extreme changes in blood pressure, increased heart rate, fever, excessive sweating, shivering or shaking, blurred vision, muscle spasm or stiffness, tremor, incoordination, stomach cramp, nausea, vomiting, and diarrhea.

Additionally, caution is advised when dextromethorphan is taken with other serotonergic drugs, such as selective serotonin reuptake inhibitors (SSRIs), serotonin-norepinephrine reuptake inhibitors (SNRIs), tricyclic antidepressants (TCAs), and triptans used for migraines, as the risk of serotonin syndrome is also increased with these combinations. Patients should be monitored closely for signs of serotonin syndrome, especially when starting or increasing the dose of these medications.

Concomitant use of dextromethorphan with other central nervous system (CNS) depressants, including alcohol, antihistamines, sedatives, tranquilizers, sleeping medications, and other narcotics, can enhance the sedative effects, leading to increased drowsiness, dizziness, and difficulty concentrating. Patients should avoid or limit the use of alcohol and be cautious when performing tasks that require alertness.

Furthermore, certain medications that inhibit the CYP2D6 enzyme, such as quinidine, fluoxetine, paroxetine, and amiodarone, can affect the metabolism of dextromethorphan and lead to increased levels of the drug in the body, potentially resulting in enhanced effects or toxicity. Patients on these medications may require dose adjustments or more careful monitoring.

It is also important to note that the slow-release nature of this formulation may alter the interaction profile compared to immediate-release forms of dextromethorphan. The extended release of the active ingredient could potentially lead to prolonged interactions with other medications. Therefore, it is crucial for prescribers to consider the timing of administration when co-prescribing other drugs.

Patients should always inform their healthcare provider of all the medications they are currently taking, including over-the-counter drugs, herbal supplements, and vitamins, to ensure safe use of dextromethorphan slow-release capsules. If you have any questions or concerns about potential drug interactions with dextromethorphan slow-release capsules, please reach out to us at Bayview Pharmacy for further assistance.

How Does it Work

A small arrow pointing down

Dextromethorphan Hydrobromide is an antitussive medication, which means it is used to suppress coughing. It works by affecting the signals in the brain that trigger the cough reflex. When formulated into a 120 mg slow-release oral capsule using Methocel E4M, the medication is designed to be released gradually into the bloodstream over an extended period. Methocel E4M is a type of hydrophilic polymer, also known as hypromellose, which swells and forms a gel when it comes into contact with water. This gel matrix creates a barrier that controls the rate at which the dextromethorphan is released from the capsule.

The slow-release mechanism is beneficial for maintaining consistent therapeutic levels of the medication in the body, which is particularly useful for managing symptoms that require round-the-clock control. By providing a steady release of dextromethorphan, these capsules help to alleviate coughing with less frequent dosing, which can improve patient compliance. This is especially important for patients who may have difficulty adhering to a more frequent dosing schedule or for those who experience disrupted sleep due to nocturnal coughing.

These slow-release capsules are indicated for the treatment of coughs resulting from various causes, including the common cold, influenza, and other respiratory conditions where cough is a primary concern. The extended release of dextromethorphan provided by the Methocel E4M polymer ensures that the therapeutic effect is sustained over a longer period compared to immediate-release formulations, which can lead to more effective symptom management and improved patient outcomes.

It is important for both patients and prescribers to understand that while the slow-release formulation offers convenience and potentially better compliance, it is essential to adhere to the prescribed dosing regimen and not to crush or chew the capsules, as this could disrupt the controlled-release mechanism and lead to the rapid release of the entire dose at once. If you have any questions about this formulation or its suitability for treating specific disease states, please reach out to us at Bayview Pharmacy for further information and guidance.

Other Uses

A small arrow pointing down

Dextromethorphan hydrobromide (DXM) is primarily recognized for its use as an antitussive, providing relief from cough. However, when formulated into slow-release capsules utilizing Methocel E4M as a polymer, the scope of its potential applications may extend to other therapeutic areas, although these are less well-established and may require further investigation. For example, some research suggests that dextromethorphan may have a role in managing certain types of neuropathic pain due to its NMDA receptor antagonist properties. This mechanism may prove useful in conditions such as diabetic neuropathy or fibromyalgia, where modulation of the NMDA receptor can be a key to symptom management.

In mental health, there have been investigations into the use of dextromethorphan for the treatment of mood disorders, with particular focus on its sigma-1 agonist activity. Though not conventionally used for this purpose and not well established in clinical practice, there is ongoing research in this area that may in future support the application of slow-release DXM formulations in managing symptoms associated with depression or anxiety. Clinical trials and further research are necessary to clarify the effectiveness and safety profile for these potential uses.

Furthermore, the slow-release mechanism provided by Methocel E4M can be particularly beneficial for patients requiring a steady plasma concentration of dextromethorphan over an extended period, which is not only convenient but may also ameliorate some side-effects associated with peak dosing. This could offer an advantage for patients with swallowing difficulties or those who find adherence to frequent dosing schedules challenging. It should be noted that while the slow-release formulation could provide certain benefits for alternative indications, the primary use of dextromethorphan remains symptomatic relief from cough, and off-label uses should always be approached with caution and under proper medical supervision.

Beyond the therapeutic effects, the slow-release formulation may also be of benefit for research purposes, especially in pharmacokinetic studies where a controlled release of the active substance is required to monitor its effects over a prolonged period. Such studies could utilize slow-release dextromethorphan capsules to gain insights into the pharmacodynamic and pharmacokinetic profiles of the drug for various potential indications.

It is critical, however, to remain cognizant that off-label uses of medications can carry risks, and therefore, prescribers should strictly follow prevailing guidelines and evidence when considering dextromethorphan for any applications beyond cough suppression. Patients should also only use the medication for its intended purposes unless advised by their healthcare provider. Should prescribers or patients have inquiries concerning the off-label use of slow-release dextromethorphan capsules or need more detailed information about this specific formulation, they are encouraged to reach out to us at Bayview Pharmacy for guidance and consultation.
