Optax (Oxybuprocaine Hydrochloride, Fluorescein Sodium)

Oxybuprocaine Hydrochloride, the active ingredient in Optax, is an ophthalmic local anesthetic presented as an ophthalmic solution for topical ocular use. It provides rapid, reversible anesthesia of the corneal surface for eye examinations and minor procedures, and when combined with Fluorescein Sodium it enables corneal and conjunctival staining for diagnostic evaluation.

GNH USA supplies Optax as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. The company ensures quality compliance with EU standards and provides reliable global distribution.

Optax, containing an ophthalmic local anesthetic and diagnostic dye, is employed in ocular surface procedures and diagnostic assessments.

- Diagnostic eye examinations: provides corneal and conjunctival staining for enhanced visualization. - Minor ocular procedures (e.g., foreign body removal): delivers topical anesthesia to reduce patient discomfort. - Contact lens fitting and tear film evaluation: enables assessment of ocular surface integrity and tear distribution.

Adverse reactions to Optax may range from mild irritation to rare serious events.

Common Side Effects: - Stinging or burning sensation upon instillation. - Transient blurred vision. - Conjunctival hyperemia. - Mild allergic conjunctivitis. - Temporary eyelid edema.

Serious or Rare Side Effects: - Corneal epithelial toxicity. - Severe allergic reaction (anaphylaxis). - Persistent corneal ulceration. - Intraocular pressure elevation.

When using Optax, consider the following precautions to ensure safety and efficacy.

- Allergy assessment: avoid use in patients with known hypersensitivity to oxybuprocaine, fluorescein or related compounds. - Contact lens wear: remove contact lenses before administration and wait before reinserting. - Active eye infection: do not apply unless directed by a clinician. - Pregnancy and lactation: use only if clearly needed after risk‑benefit evaluation. - Concomitant ocular medications: assess potential interactions before co‑administration. - Store at room temperature: keep in the original container, protect from light and moisture.

Optax may interact with other ophthalmic agents; consider the following.

Major Interactions (Avoid): - Systemic sulfonamides: may increase risk of severe allergic reactions to fluorescein. - Topical anesthetic agents: combined use can lead to additive corneal toxicity. - Preservative‑containing contact lens solutions: may cause heightened ocular irritation.

Moderate Interactions (Monitor Closely): - Non‑steroidal anti‑inflammatory eye drops: may increase ocular surface irritation. - Anticholinergic ophthalmic drops: may affect pupil response during diagnostic staining. - Topical beta‑blockers: monitor intraocular pressure if used concurrently.
