Description:
Mechanism of Action: Sodium hyaluronate, a high molecular weight fraction of purified natural sodium hyaluronic acid, is widely distributed in the extracellular matrix of connective tissues (particularly in the synovial fluid, umbilical cord, skin, and vitreous and aqueous humour of the eye). It acts as a viscoelastic space filler during ophthalmic surgery and functions as a tissue/joint lubricant to regulate the interactions between adjacent tissues. Topically, it protects the skin against abrasion, friction and desiccation.

Topical cream or gel/ophthalmic solution: Store below 30°C. Intraocular inj: Store between 2-25°C. Do not freeze. Protect from light. Intra-articular inj: Store below 30°C. Do not freeze. Protect from light. Storage recommendations may vary among individual products or between countries (refer to detailed product guidelines).
