The present invention generally relates to formulations and methods for treating oral inflammation, oral injury and/or oral pain by applying hydrogel, viscous liquid, or other formulation to the oral cavity. Wet formulations comprise a hydrophilic polymer selected from the group consisting of pyrrolidones, hyaluronic acid and salts thereof, alginic acid and salts thereof, and carrageenans and salts thereof; calcium salts or ions, phosphate salts or ions, and water as well as other optional components. Dry formulations such as powders are also contemplated.

Formulations and methods for treating oral inflammation, injury, or pain

A method of anti-metastatic and/or anti-inflammatory treatment of an animal or human patient comprises administration to the patient of an effective amount of at least one sulphated polysaccharide which blocks or inhibits endoglycosidase, particularly heparanase, activity. Suitable sulphated polysaccharides include heparin and modified heparin, fucoidan, pentosan sulphate, dextran sulphate and carrageenan lambda.

Sulphated polysaccharides having anti-metastatic and/or anti-inflammatory activity

In vitro studies using cells transfected with acid-sensing ion channel 3 (ASIC3) or acid-sensing ion channel 1 (ASIC1) cDNA, demonstrated that the miRNAs against mouse ASIC3 (miR844 and miR847) selectively inhibit mouse ASIC3, but not ASIC1 as detected by protein expression and responses to pH. When the RNAi agents, miR844 or miR847, were used in vivo, delivered into the muscle of mice using a replication-defective herpes simplex viral (HSV-1) vector, primary and secondary hyperalgesia were reduced after carrageenan-induced muscle inflammation. Accordingly, the present invention provides RNAi agents that target ASIC3, methods of preparing such RNAi agents, and methods of using them to modulate in a cell the level of ASIC3 or activity of an ASIC including at least one ASIC3. Modulation of ASIC3 activity or levels can be used for different purposes such as treating pain associated with the expression of ASIC3 and the like.
