Description

Rx symbolFDA-approved intravenous and intra-articular therapy available to treat non-infectious synovitis associated with osteoarthritis in horses. Hyaluronate sodium is the glycosaminoglycan present in normal joint fluid. It is produced by a patented biofermentation process that results in such purity that it can be given intravenously for immediate bioavailability.

NexHA, a generic form of Hyaluronate Sodium has now been approved by the FDA is a formulation of purified hyaluronate sodium that can be administered to horses by intravenous or intra-articular injection.

Usage

Hyaluronate sodium is used in the healing of degenerative joint disease. One major function is the regulation of normal cell constituents that decrease the impact of exudation, enzyme release, and subsequent degradation of joint integrity. Injected directly into the joint pouch, it enhances the healing of the inflamed synovium by restoring lubrication of the joint fluid. It also exerts an anti-inflammatory action.

NexHA, the generic form of hyaluronate sodium is indicated in the treatment of joint dysfunction of the carpus or fetlock in horses due to non-infectious synovitis associated with equine osteoarthritis. Hyaluronate sodium acts as a replacement for synovial fluid, the naturally occurring lubricant in articular joints.
