Liposic

Carbomer, the active ingredient in Liposic, is a viscosity agent presented as an ophthalmic solution for ocular use. It provides thickening and stabilising functions in eye‑drop formulations, enhancing drug residence time on the ocular surface and improving patient comfort. Its high molecular weight polymer structure allows precise control of viscosity across a wide pH range, making it suitable for diverse ophthalmic products.

GNH USA supplies Liposic as a licensed, GDP‑compliant international pharmaceutical supplier, sourced from the European Union and serving hospitals, transplant centres, oncology centres, pharmacies and clinics worldwide with consistent quality and regulatory compliance.

Liposic, a carbomer‑based ophthalmic vehicle, is employed to modify the viscosity of ocular drug formulations, supporting a range of eye‑drop therapies. - Artificial tear formulations: enhances lubrication and prolongs tear film stability, improving comfort for patients with dry eye syndrome. - Antibiotic eye drops: stabilises suspension of active agents, ensuring uniform dosing and reducing sedimentation during storage. - Anti‑inflammatory eye drops: provides muco‑adhesive properties that increase contact time of corticosteroids or NSAIDs on the ocular surface. - Glaucoma medications: improves formulation stability and patient tolerance by reducing wash‑out effect.

Liposic is generally well tolerated, but ocular administration can be associated with local adverse reactions.

Common Side Effects: - Transient eye irritation: mild burning or stinging sensation immediately after instillation. - Temporary blurred vision: short‑term reduction in visual clarity that resolves within minutes. - Increased tearing: reflex lacrimation that may occur following application. - Conjunctival redness: mild hyperemia of the eye surface.

Serious or Rare Side Effects: - Allergic reaction: swelling, itching, or rash around the eye indicating hypersensitivity. - Corneal edema: rare swelling of the cornea that may impair vision and requires prompt evaluation. - Severe ocular inflammation: uveitis or keratitis potentially linked to formulation contamination.

When using Liposic, appropriate precautions help minimise irritation and maintain product integrity. - Patient counseling: advise users not to touch the dropper tip to the eye or any surface to avoid contamination. - Avoid contaminated solutions: discard the product if the container is opened for longer than the recommended period or shows signs of microbial growth. - Monitor for allergy: watch for signs of hypersensitivity such as swelling, itching, or rash and discontinue use if they appear. - Do not use if discolored: stop using the solution if it becomes cloudy, changes colour, or develops particles. - Store at room temperature: keep the bottle in its original packaging, protect from moisture and direct sunlight, and store below 25 °C.

Carbomer can interact with certain formulation components, potentially affecting viscosity or stability.

Major Interactions (Avoid): - Cationic preservatives (e.g., benzalkonium chloride): may cause precipitation or reduced gel formation. - Divalent metal ions (e.g., calcium, magnesium): can diminish gelling efficiency and alter viscosity.

Moderate Interactions (Monitor Closely): - Other polymers (e.g., hyaluronic acid): may modify the overall viscosity profile of the final product. - pH‑adjusting agents: extreme pH levels can affect polymer ionisation and gel strength. - High ionic strength solutions: elevated salt concentrations may decrease viscosity and affect stability.
