What is Carbomer?

Carbomer, the active ingredient in Liposic, is a excipient presented as an unknown/unknown for ocular use. It functions as a viscosity‑enhancing excipient in ophthalmic formulations, helping to stabilize the tear film and prolong drug residence on the eye surface. GNH USA supplies Liposic as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

What is Carbomer used for?

Liposic, containing carbomer, is used in ophthalmic formulations to manage ocular surface conditions.

Dry eye syndrome: provides lubrication and improves tear film stability. Post‑operative ocular care: serves as a vehicle to enhance retention of anti‑inflammatory agents. Contact lens discomfort: increases ocular surface viscosity to improve comfort.

What are the side effects of Carbomer?

Liposic may cause ocular reactions, most of which are mild and transient.

Common Side Effects: - Stinging or burning sensation upon instillation. - Transient blurred vision. - Redness of the conjunctiva. - Tearing or excess lacrimation. - Foreign body sensation. - Mild ocular irritation.

Serious or Rare Side Effects: - Severe allergic reaction (e.g., ocular edema, hives). - Corneal ulceration. - Persistent inflammation or keratitis. - Vision loss. - Hypersensitivity leading to conjunctival swelling. - Significant increase in intra‑ocular pressure.

What precautions apply to Carbomer?

When using Liposic, consider the following safety measures.

Allergy assessment: verify no known hypersensitivity to carbomer or related polymers. Contact lens wearers: remove lenses before application and re‑insert after the recommended interval. Pregnancy and lactation: use only if clearly needed and under professional guidance. Concurrent ocular medications: avoid mixing with other drops unless advised by a clinician. Eye surgery: inform the surgeon of Liposic use prior to any procedure. Store at ambient temperature: keep in the original pack, protect from moisture and direct sunlight.

What does Carbomer interact with?

Liposic may interact with other ophthalmic products; monitor for compatibility.

Major Interactions (Avoid): - Preservative‑containing drops that may precipitate with carbomer. - pH‑altering agents that can destabilise the gel matrix.

Moderate Interactions (Monitor Closely): - Topical antibiotics: may have reduced efficacy. - Anti‑glaucoma eye drops: monitor intra‑ocular pressure. - Contact lens solutions: may cause irritation. - Anti‑inflammatory eye drops: assess for additive viscosity effects.

Frequently asked questions

What is Liposic used for?+
Liposic is a carbomer‑based ophthalmic excipient used to increase viscosity in eye drops, providing lubrication and prolonged residence time on the ocular surface, commonly employed in artificial tears and post‑operative eye formulations.
How does carbomer work?+
Carbomer is a high‑molecular‑weight acrylic acid polymer that swells in aqueous media to form a gel matrix. In ophthalmic solutions it creates a viscous, muco‑adhesive layer that stabilises the tear film, enhances drug retention, and reduces evaporation, thereby improving comfort and therapeutic efficacy.
What is the usual dose of Liposic?+
The dosage of Liposic is determined by the prescribing ophthalmologist or pharmacist based on the specific formulation and patient needs. Typical administration involves instilling one to two drops into the affected eye(s) as directed, with frequency ranging from several times daily to as needed.
Is Liposic safe in pregnancy or breastfeeding?+
Carbomer is classified as an inert excipient with limited systemic absorption. While no specific contraindications have been reported, use during pregnancy or lactation should only be undertaken if the potential benefit outweighs any theoretical risk, and under the guidance of a qualified healthcare professional.
How do I order Liposic from GNH USA?+
To place an order, submit an enquiry on the Liposic product page at gnh-usa.com, specifying the required quantity. GNH USA works with hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details (including any cold‑chain requirements) and necessary import documentation.
How does Liposic compare with alternative excipients?+
Compared with other ophthalmic viscosity agents such as hyaluronic acid or hydroxypropyl methylcellulose, carbomer offers a high degree of thickening at low concentrations and forms clear, non‑cloudy gels. It provides rapid viscosity build‑up and good stability, though some patients may experience transient stinging, whereas hyaluronic acid may be better tolerated but is more costly.
What are the storage and handling requirements for Liposic?+
Liposic should be stored at ambient temperature, preferably below 25 °C, in its original sealed container. Protect the product from moisture, direct sunlight and extreme temperature fluctuations. Do not freeze. Before use, inspect the container for any signs of contamination or degradation and discard if the appearance changes.
How is Liposic administered?+
Liposic is supplied as an ophthalmic gel or solution intended for topical ocular use. The patient should wash hands, tilt the head back, and instill the prescribed number of drops into the conjunctival sac of each eye, avoiding contact between the dropper tip and the eye or surrounding tissues. The medication may be used with or without contact lenses, depending on the clinician’s advice.
What are the most serious risks to watch for with Liposic?+
Although carbomer is generally well tolerated, rare but serious adverse events can include severe allergic reactions such as ocular edema, conjunctival hyperemia, or corneal ulceration. Patients should discontinue use and seek immediate medical attention if they experience intense pain, vision changes, swelling, or persistent redness, as these may indicate a hypersensitivity or complication requiring prompt evaluation.
Who should not use Liposic?+
Liposic should be avoided in individuals with a known hypersensitivity to carbomer or any component of the formulation. It is also contraindicated in patients who have experienced severe ocular inflammation or infection that could be aggravated by a viscous agent, and in those where the prescribing clinician determines that alternative therapy is more appropriate.
