Intended Use

CARAPASTE® Oral Wound Dressing forms a protective layer over the oral mucosa by adhering to the mucosal surface which allows it to protect against further irritation and relieve pain. The paste may be used in the management of mouth lesions of all types including aphthous ulcer, stomatitis, mucositis, minor lesions, chafing and traumatic ulcers, abrasions caused by braces and ill fitting dentures, and lessions associated with oral surgery.

Device Story

CARAPASTE® is an amorphous hydrogel paste composed of sucralfate reacted with hydrochloric acid. It functions as a physical wound dressing by adhering to oral mucosal surfaces to form a protective film. This barrier protects lesions from irritation and provides pain relief. The device is applied directly to accessible oral wounds. It is intended for use in clinical or home settings to manage various mouth lesions, including ulcers, stomatitis, and surgical abrasions. The self-buffering paste (pH ~3.5) acts as a mechanical barrier to promote healing.

Clinical Evidence

No clinical data provided; substantial equivalence based on technological characteristics and intended use.

Technological Characteristics

Amorphous hydrogel paste; composition: sucralfate reacted with hydrochloric acid; self-buffering to pH ~3.5; physical barrier mechanism; non-sterile (implied by topical application); no electronic or software components.

Indications for Use

Indicated for management of oral mucosal lesions in patients of all ages, including aphthous ulcers, stomatitis, mucositis, minor lesions, chafing, traumatic ulcers, abrasions from braces or dentures, and post-oral surgery lesions.

Regulatory Classification

Identification

Intended as a physical barrier for temporary protection of oral mucosal tissue and to provide pain relief. Unclassified status per SE to MGQ.

### 4. Device Description

CARAPASTE ® Oral Wound Dressing, Sucralfate HCl Topical Paste, is an amorphous hydrogel paste formed by the controlled reaction of sucralfate with a limited quantity of hydrochloric acid. The amorphous hydrogel paste formed by this reaction binds reversibly to wounds and is intended to form a protective film that covers lesions where gastric acid or local wound bed acidity is not available or is inconsistently present. CARAPASTE ® Oral Wound Dressing may be administered directly to an accessible oral wound to provide an adherent physical covering of the wound bed. Although prepared by reaction of sucralfate with strong acid, the polymerized sucralfate self-buffers to a pH of approximately 3.5.

#### ട. Intended Use of the Device

CARAPASTE® Oral Wound Dressing forms a protective layer over the oral mucosa by adhering to the mucosal surface which allows it to protect against further irritation and relieve pain. The paste may be used in the management of mouth lesions of all types including aphthous ulcer, stomatitis, mucositis, minor lesions, chafing and traumatic ulcers, abrasions caused by braces and ill fitting dentures, and lessions associated with oral surgery.

## 6. Summary of Technological Characteristics of the Device Compared to the Predicate Devices

CARAPASTE® Oral Wound Dressing forms a protective layer over the oral mucosa, adheres to the mucosal surface and relieves pain and promotes wound healing of mouth lesions.

### 7. Conclusions

The physical wound covering properties of CARAPASTE® Oral Wound Dressing would be expected to be at least as effective as those of the predicate devices. No new biocompatibility or other safety issues are raised.
