Understanding a Key Supportive Medication: What is Neutrasal Used For?

Up to 100% of patients receiving radiation and chemotherapy for head and neck cancer develop oral mucositis, a painful side effect [1.4.4]. A key question for these patients is, what is Neutrasal used for? It is a prescription rinse designed to manage this condition.

Quick Summary

Neutrasal is primarily used as an adjunct treatment for the discomfort of oral mucositis from high-dose chemotherapy or radiation and to relieve dryness of the oral mucosa (xerostomia) [1.2.1, 1.2.3].

Key Points

• Primary Use: Neutrasal is primarily used to treat oral mucositis from cancer therapy and xerostomia (dry mouth) [1.2.1].

• Mechanism of Action: It's a powder that dissolves into a supersaturated calcium phosphate rinse, mimicking natural saliva [1.3.1].

• Restores Balance: The rinse helps restore a normal pH and ionic balance in the oral cavity, which can be disrupted by medical treatments [1.3.3].

• Two Main Conditions: It addresses both painful mouth sores (mucositis) and the discomfort of severe dry mouth [1.2.3, 1.6.4].

• Prescription Required: Neutrasal is a medical device that requires a prescription from a doctor or dentist [1.5.3, 1.7.1].

• Administration: Users dissolve a packet in water and rinse twice for one minute each, avoiding food or drink for 15 minutes after [1.7.1, 1.7.4].

• Safety: It is not intended for systemic use and should be spit out, though no adverse effects are anticipated if accidentally swallowed [1.3.6, 1.7.4].

What is Neutrasal?

Neutrasal is a prescription oral rinse designed to mimic natural saliva and treat uncomfortable and painful oral conditions [1.3.4, 1.6.4]. It comes as a powder in single-use packets that are dissolved in water to create a supersaturated calcium phosphate solution [1.3.1]. This solution is formulated to help restore the normal ionic and pH balance in the oral cavity, which can be disrupted by medical treatments or certain health conditions [1.3.3, 1.5.4]. It is primarily indicated as a supportive care medication in oncology to manage the side effects of cancer treatments [1.4.1].

The Pharmacology: How Does Neutrasal Work?

Neutrasal's mechanism of action lies in its unique formulation. The powder contains a blend of salts, including sodium phosphates, calcium chloride, and sodium bicarbonate [1.5.1, 1.5.2]. When dissolved in water, these components form a solution that is supersaturated with calcium and phosphate ions—the building blocks of healthy teeth and essential components of saliva [1.3.1, 1.7.5].

This rinse works in several ways:

• Mimics Natural Saliva: The solution is designed to replicate the electrolyte composition of human saliva, helping to lubricate the mouth and alleviate the sensation of dryness [1.5.4, 1.6.5].
• Restores pH Balance: Cancer treatments and dry mouth can create an acidic oral environment. Neutrasal helps to neutralize this acidity, restoring a healthy oral pH which can reduce the risk of tooth decay [1.3.2, 1.3.3].
• Promotes Healing: The calcium and phosphate ions can help in the healing and repair of inflamed and damaged oral tissues (mucosa) [1.3.3]. By providing these essential minerals, it supports the integrity of the oral lining.

Primary Indications: What is Neutrasal Used For?

Neutrasal has two main FDA-recognized indications: one by prescription (Rx) and one available over-the-counter (OTC) for less severe conditions [1.2.1].

Combating Oral Mucositis (Prescription Use)

Oral mucositis is a severe and painful inflammation and ulceration of the mucous membranes lining the mouth. It is a common and debilitating side effect for patients undergoing high-dose chemotherapy and/or radiation therapy, especially for head and neck cancers [1.4.1, 1.4.4]. The condition can make it difficult to eat, speak, and swallow, significantly impacting a patient's quality of life and potentially interrupting cancer treatment [1.8.2].

Neutrasal is prescribed as an adjunct to standard oral care to relieve the discomfort associated with mucositis [1.2.1, 1.2.3]. Clinical studies have shown its effectiveness in reducing the severity of oral mucositis in cancer patients [1.4.1, 1.4.5]. For this use, patients may rinse up to 10 times a day, especially when pain is significant [1.4.2, 1.7.2].

Alleviating Xerostomia (Dry Mouth)

Neutrasal is also indicated for xerostomia, or severe dry mouth [1.6.2, 1.6.4]. This condition can be caused by a variety of factors, including:

• Side effects of medications like antihistamines and anticholinergics [1.6.1, 1.6.3].
• Radiation therapy to the head and neck, which can damage salivary glands [1.3.6].
• Autoimmune diseases such as Sjögren's syndrome [1.6.4].
• Other medical conditions causing salivary gland hypofunction [1.4.1].

By replacing the moisture and essential ions found in saliva, Neutrasal helps to relieve the diffuse dryness, facilitate chewing and speaking, and improve overall oral comfort [1.3.1]. For general dry mouth relief, it is typically used 2 to 10 times per day as needed [1.6.6].

How to Use Neutrasal Correctly

Proper administration is crucial for Neutrasal's effectiveness. The process is straightforward:

1. Dissolve: Empty the entire contents of one Neutrasal powder packet into a clean glass with 1 ounce (30 mL or 2 tablespoons) of tap water [1.7.1, 1.7.3].
2. Stir: Stir the solution until the powder is fully dissolved and the liquid is clear [1.7.5].
3. Rinse (First Half): Immediately swish with half of the solution (about 15 mL) for one full minute, ensuring it coats all surfaces of the mouth [1.7.1].
4. Spit: Spit out the solution. Do not swallow it [1.7.4].
5. Rinse (Second Half): Repeat the one-minute swish with the remaining half of the solution and spit it out [1.7.1].
6. Wait: Avoid eating or drinking for at least 15 minutes after using the rinse to allow the active ingredients to work [1.7.4].

Conclusion

So, what is Neutrasal used for? It is a specialized, prescription-strength oral rinse that plays a crucial role in supportive care, particularly for oncology patients. Its primary functions are to manage the painful symptoms of oral mucositis caused by chemotherapy and radiation and to provide significant relief from xerostomia (dry mouth) from various causes [1.2.1, 1.6.4]. By creating a supersaturated calcium phosphate solution that mimics natural saliva, Neutrasal helps to restore a healthy oral environment, soothe damaged tissues, and improve the quality of life for those suffering from these challenging conditions [1.3.2, 1.3.3].
