MucoPEG™ is an artificial saliva intended to relieve the symptoms and discomfort of xerostomia (dry mouth) and was developed by SunBio, Inc. The main ingredient of MucoPEG™ is a polyethylene glycol (PEG) derivative. The full chemical name of this ingredient is PEG tetra succinimidyl glutarate (PEG-SG). The additives in MucoPEG™ include mint for flavor and sodium bicarbonate for pH maintenance when dissolved in water. MucoPEG™ is formulated as a powder and packaged in a single-use packet. In general, PEG is well known for its excellent moisturizing effect in aqueous solutions due to its superior water-retaining capability. Therefore, the PEG derivative in MucoPEG™ also naturally exhibits the hydrophilic characteristics of PEG. Once in contact with the mucosa, the hydrophilic water-retaining property of PEG helps moisturize and lubricate the oral mucosa, thereby helping to relieve oral dryness. The oral mucosa of xerostomia patients consists of damaged epithelial cell layers caused by dryness. When MucoPEG™ is applied to the mucosa of xerostomia patients, it effectively fills and coats the damaged epithelial areas to relieve dry mouth symptoms and discomfort.
An electrolyte solution resembling human saliva designed in part to replace the normal ionic and pH balance of the oral cavity. The device is intended as a mouth rinse to moisten, lubricate, and clean the mucosa of the mouth, tongue, and throat. The device is indicated for dryness of the mouth or throat due to temporary or permanent conditions. After application, this device cannot be reused.
