NEW: HAPPYVISC®, 1.55% Hyaluronic Acid + Mannitol to treat knee osteoarthritis (3 x 2ml syringes)
SECOND GENERATION VISCOSUPPLEMENT
INDICATED IN THE TREATMENT OF KNEE OSTEOARTHRITIS
HYALURONIC ACID + MANNITOL
MEDICAL DEVICE – 3 x 2 ml pre-filled syringes
High Molecular Weight
HAppyVisc™ is a visco-elastic gel which combines high molecular weight hyaluronic acid of 1.5 million Daltons and mannitol.
High concentration for prolonged activity
HAppyVisc™ contains high concentration of hyaluronic acid (1.55%) i.e. 31 mg/syringe. HAppyVisc™ brings 50% more hyaluronic acid than a traditional visco-elastic solution.
HAppyVisc™ contains high concentration of mannitol (70 mg/syringe).
Long-lasting effect: Mannitol is an anti-oxidant which protects hyaluronic acid chains from free radicals and limits their degradation increasing then their residence time in the joint cavity.
Analgesic effect: Due to its free radical scavenging properties, mannitol also ensures local analgesic effect.
Stabilizer: Because it is a thermal stabilizer, mannitol allows HAppyVisc™ to guarantee a stability of its rheological properties all along its storage.
HAppyVisc™ is highly purified and results from bacterial fermentation.
