Ophthalmic preparations, such as eye drops and artificial tears, require excipients that offer not only efficacy but also exceptional safety and comfort. Hypromellose (HPMC) has long been recognized as a vital ingredient in these formulations, acting as a viscosity enhancer, lubricant, and tear substitute. NINGBO INNO PHARMCHEM CO.,LTD., as a leading manufacturer and supplier of pharmaceutical grade HPMC, provides essential insights into the crucial role HPMC plays in ophthalmic care.

Hypromellose is a semi-synthetic polymer derived from cellulose, known for its excellent biocompatibility and safety profile. In ophthalmic solutions, its primary function is to increase the viscosity of the formulation. This enhanced viscosity prolongs the contact time of the active drug or therapeutic agent with the ocular surface. For patients suffering from dry eye syndrome, this means extended lubrication and relief from discomfort. The ability of HPMC to form a clear, stable solution that mimics the natural tear film makes it an ideal candidate for these sensitive applications.

Key Functions of HPMC in Ophthalmic Solutions:

  • Viscosity Enhancement: HPMC significantly increases the viscosity of eye drops, providing a comforting and lubricating effect. This is crucial for formulations designed to alleviate dry eye symptoms.
  • Lubrication: It acts as a lubricant for the eye, reducing friction and irritation, especially in environments with low humidity or prolonged screen use.
  • Tear Substitute: HPMC solutions can augment the natural tear film, helping to stabilize it and provide a longer lasting moisture layer on the cornea.
  • Drug Delivery: By increasing residence time, HPMC can also enhance the ocular absorption and efficacy of specific active ingredients within the formulation.
  • Safety and Biocompatibility: HPMC is well-tolerated by ocular tissues and has a long history of safe use in ophthalmic products.
