Lacrinorm

Carbomer 980, the active ingredient in Lacrinorm, is an excipient presented as an ophthalmic viscosity agent for ocular use. It forms a gel matrix that enhances tear film stability and prolongs drug residence time on the eye surface, supporting comfort in dry eye and postoperative conditions.

GNH USA supplies Lacrinorm as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, transplant centres, oncology centres, pharmacies and clinics worldwide. The company adheres to stringent quality standards and provides regulatory documentation for export to global markets.

Lacrinorm, containing Carbomer 980, is employed as an ophthalmic viscosity enhancer in several ocular surface conditions.

- Dry eye syndrome: improves tear film stability and reduces ocular discomfort. - Post‑operative ocular care: prolongs residence time of therapeutic drops after eye surgery. - Contact lens wear intolerance: enhances lubrication to increase comfort for lens users.

The ophthalmic formulation containing Carbomer 980 may be associated with the following ocular adverse reactions.

Common Side Effects: - Transient blurred vision: temporary reduction in visual clarity after instillation. - Mild ocular irritation: sensation of stinging or burning upon application. - Temporary tearing: increased lacrimation shortly after use.

Serious or Rare Side Effects: - Allergic conjunctivitis: redness, swelling, and itching indicating hypersensitivity. - Corneal epithelial defect: rare disruption of the corneal surface requiring medical attention. - Persistent intraocular inflammation: prolonged inflammation that may need intervention.

When using Lacrinorm, consider the following precautions to ensure safety and product integrity. - Avoid contamination: use a sterile applicator and do not touch the tip to any surface. - Discontinue if severe irritation occurs: seek ophthalmic evaluation promptly. - Do not use with compromised ocular barriers: patients with active corneal ulcers should avoid. - Monitor for hypersensitivity: watch for signs of allergic reaction during initial applications. - Store at ambient temperature: keep the container tightly closed, protect from direct light and moisture.

Carbomer 980 generally exhibits low potential for drug‑drug interactions, but certain combinations may require attention.

Major Interactions (Avoid): - Concurrent use with preservative‑rich eye drops: may increase ocular irritation. - Formulations containing strong surfactants: can destabilize the gel matrix.

Moderate Interactions (Monitor Closely): - Co‑administration with other viscosity‑enhancing agents: assess for excessive thickening. - Use with topical antibiotics: monitor for altered drug distribution. - Combination with anti‑inflammatory eye drops: observe for changes in therapeutic effect.
