## Intended Use

(OTC): Neutrasal® is indicated for the dryness of the mouth (hyposalivation, xerostomia) (OTC): Neutrasal® is also indicated for dryness of the oral mucosa due to drugs such as antihistamines or atropine or other anticholinergic agents that suppress salivary secretion. (OTC): Neutrasal® may be used as part of an oral hygiene program for patients with dry mouth. Neutrasal® also provides intensive hygiene of the oral cavity. (Rx): Neutrasal® is also indicated as an adjunct to standard oral care in relieving the discomfort associated with oral mucositis that may be caused by radiation or high dose chemotherapy. Relief of dryness of the oral mucosa in these conditions is associated with amelioration of pain. (Rx): Neutrasal® may be used for relief of dryness of the oral mucosa when hyposalivation results from the following: surgery, radiotherapy near the salivary glands, chemotherapy, infection or dysfunction of the salivary glands; fever; emotional factors such as fear or anxiety; obstruction of the salivary ducts; Sjögren's syndrome

## Device Story

Neutrasal is a powder formulation containing calcium chloride, sodium phosphate, sodium bicarbonate, and silica gel. When dissolved in tap water, it creates a supersaturated calcium and phosphate oral rinse. Used by patients in home or clinical settings to restore oral ionic/pH balance, maintain moisture, and loosen mucus. Effervescent formulation enhances mucosal penetration. Provides relief from dryness, fissuring, and painful tongue conditions; facilitates chewing and speaking; improves denture adherence. Acts as an adjunct to standard oral care for mucositis pain relief. No complex electronics or software involved.

## Clinical Evidence

Bench testing only. Performance testing included assessment of physical properties, pH, dissolution, activity of the supersaturated state, and content testing of active ingredients. Biocompatibility is claimed to be identical to the predicate device.

## Technological Characteristics

Powder formulation consisting of calcium chloride, sodium phosphate, sodium bicarbonate, and silica gel (anti-caking agent). Dissolves in water to form a supersaturated calcium and phosphate electrolyte solution. Non-sterile. No software or electronic components.

## Predicate Devices

- Caphosol ([K030802](/device/K030802.md), [K991938](/device/K991938.md))
- Neutrasal ([K091718](/device/K091718.md))

{1}------------------------------------------------

# D. Device Description:

Neutrasal® is a powder that when dissolved in normal tap water becomes a supersaturated calcium and phosphate rinse. Neutrasal® was designed in part to replace the normal ionic and pH balance in the oral cavity. Neutrasal® also maintains moistness in the oral cavity. It relieves diffuse dryness and fissuring of the oral mucosa, as well as painful tongue conditions due to hyposalivation.

Neutrasal® facilitates chewing and speaking; loosens tough mucus; prevents mucous membranes from sticking together; and improves adherence of dentures.

Additionally, Neutrasal® can be used as an adjunct to standard oral care for relieving the discomfort associated with oral mucositis that may be caused by high dose chemotherapy or radiation. Relief of dryness of the oral mucosa in these conditions is associated with an amelioration of pain.

Neutrasal® is a comprised of calcium chloride, sodium phosphate and sodium bicarbonate plus inactive ingredients. When Neutrasal® is dissolved in normal tap water, the water becomes supersaturated with both calcium and phosphate ions.

Silica gel, an inactive ingredient in Neutrasal, is an amorphous silica that is recommended for free-flow and anti-caking for hydrogscopic food powders, industrial powders and other applications (pharmaceuticals) where humidity must be kept to a minimum.

and implement to address the identified risks factors based on the criticality of failure mode. All established GMPs will assure that device manufactured meets all established specifications prior to release and is safe and effective for its intended use.

# G. Summary of Non-Clinical Testing: Performance

The Performance Testing of Neutrasal® included the assessment of the physical properties of Neutrasal® and its ability to achieve its intended use. Bench testing was completed by Scientech Laboratories, Inc., an FDA-approved analytical laboratory testing service as well internal testing done. The following bench tests were performed:

- . pH
- Dissolution Tests .
- Activity Testing of Supersaturated State .
- Content Testing of Active Ingredients .

### H. Biocompatibility testing

Neutrasal® is identical to the 510(k)-approved product predicate product Neutrasal.

# I. GRAS Listing of Ingredients

The EAFUS list of substances contains ingredients added directly to food or medications that FDA has either approved as food additives or listed or affirmed as GRAS (generally recognized as safe). All ingredients contained in Neutrasal® are EAFUS approved food additives labeled as GRAS. Only USP-approved chemicals, with validation, will be used during the manufacturing of Neutrasal®.

{4}------------------------------------------------

#### Other Information J.

Effervescence has proved it utility as an oral drug delivery system that offers advantages to other forms of drug delivery. Neutrasal® offers more portability because it is more easily transported than liquid medication because no water is added until the product is ready to use. Additionally, Neutrasal® offers improved penetration in to the oral mucosa because of the effervescent formulation enhancement of sodium bicarbonate.

# K. Substantial Equivalence Conclusion

The indications of use, technological properties, performance testing for Neutrasal® (Powder for supersaturated calcium phosphate rinse) are identical to Neutrasal (supersaturated calcium phosphate rinse). They both share the same labeling and intended uses.
