What is Povidone K25?

Povidone, the active ingredient in Oculac, is an excipient presented as a sterile ophthalmic solution for ocular use. It functions as a viscosity enhancer and stabilizer in eye drop formulations, supporting moisture retention and drug delivery.

GNH USA supplies Oculac as a licensed, GDP-compliant international pharmaceutical supplier serving hospitals, transplant centres, oncology centres, pharmacies and clinics worldwide.

What is Povidone K25 used for?

Oculac, containing povidone, is used as a vehicle or stabilizer in ophthalmic formulations targeting ocular surface conditions.

- Dry eye syndrome: provides lubrication and tear‑film stability to relieve discomfort. - Post‑operative eye care: serves as a protective carrier for active agents after eye surgery. - Contact lens wear: maintains moisture and comfort during lens use. - Allergic conjunctivitis: helps dilute and deliver anti‑allergic agents, reducing irritation.

What are the side effects of Povidone K25?

Oculac may cause ocular and systemic reactions; reported side effects are categorized by frequency.

Common Side Effects: - Transient blurred vision: temporary visual disturbance after instillation. - Mild ocular redness: slight irritation of the conjunctiva. - Itching or burning sensation: brief discomfort upon application. - Excessive tearing: increased lacrimation that resolves quickly.

Serious or Rare Side Effects: - Severe allergic reaction: swelling, rash, or hives requiring medical attention. - Corneal ulceration: damage to the cornea that can impair vision. - Vision loss: sudden decrease in visual acuity indicating a serious ocular event.

What precautions apply to Povidone K25?

Before using Oculac, consider the following safety measures.

- Allergy assessment: verify no known hypersensitivity to povidone. - Active eye infection: avoid use unless directed by a specialist. - Contact lens wear: remove lenses before instillation unless product label permits. - Pregnancy and lactation: use only if the benefit outweighs potential risk. - Store at ambient temperature: keep in the original container, protect from light and moisture.

What does Povidone K25 interact with?

Oculac can interact with other ophthalmic products; monitor for combined effects.

Major Interactions (Avoid): - Preservative‑containing drops: may increase ocular irritation. - Systemic antihistamines: can reduce tear production, diminishing lubricating effect. - Topical ophthalmic antibiotics: may alter formulation stability.

Moderate Interactions (Monitor Closely): - Contact lens solutions with disinfectants: watch for discomfort. - Other ocular lubricants: assess for additive viscosity that could affect vision.

Frequently asked questions

What is Oculac used for?+
Oculac is an ophthalmic solution whose active ingredient povidone functions as an excipient. It is employed as a lubricating vehicle in eye drops, providing moisture, stabilizing active agents, and supporting comfort in conditions such as dry eye, post‑surgical care, and contact lens wear.
How does povidone work?+
Povidone is a water‑soluble polymer that forms hydrogen bonds with ocular surface proteins, increasing viscosity and creating a protective film. This film retains moisture, reduces friction, and can bind and stabilize active pharmaceutical ingredients, enhancing their residence time on the eye.
What is the usual dose of Oculac?+
The dosage of Oculac is determined by the prescribing clinician based on the specific indication and patient needs. Typical regimens involve one to two drops instilled into the affected eye(s) as often as required, but the exact frequency and duration must be individualized by a healthcare professional.
Is Oculac safe during pregnancy or breastfeeding?+
Safety data for povidone‑based ophthalmic solutions in pregnancy and lactation are limited. Because it is minimally absorbed systemically, it is generally considered low risk, but use should only occur when the potential benefit justifies any possible risk, and the decision should be made by the treating physician.
How do I order Oculac from GNH USA?+
To place an order, submit an enquiry on the 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 and any necessary import documentation.
How does Oculac compare with other ocular lubricants?+
Compared with traditional artificial tears, Oculac’s povidone base offers higher viscosity and better film‑forming properties, which can prolong ocular surface coverage. It also serves as a stabilizer for co‑formulated active agents, whereas many simple saline‑based drops lack this dual function. Choice depends on clinical need and physician preference.
What are the storage and handling requirements for Oculac?+
Oculac should be stored at ambient temperature, preferably below 25 °C, in its original sealed container. Protect the solution from direct sunlight, excessive heat and moisture. Once opened, use within the period indicated on the label and discard any remaining product after the recommended after‑opening date.
How is Oculac administered?+
Oculac is applied topically to the eye as a sterile drop. The patient should wash hands, tilt the head back, pull down the lower eyelid to create a pocket, and place the prescribed number of drops into the conjunctival sac. Avoid touching the dropper tip to any surface to maintain sterility.
What are the most serious risks to watch for?+
Although rare, serious adverse reactions can include severe ocular inflammation, allergic hypersensitivity leading to swelling or ulceration, and vision‑impairing events. Patients should seek immediate medical attention if they experience intense redness, pain, loss of vision, or signs of an allergic reaction after using Oculac.
Who should not use Oculac?+
Individuals with a known hypersensitivity to povidone or any component of the formulation should avoid Oculac. It is also contraindicated in eyes with active infection unless directed by a specialist, and patients wearing contact lenses should remove lenses before instillation unless the product label specifically permits concurrent use.
