Ophtesic (Anhydrous Lidocaine Hydrochloride)

Lidocaine Hydrochloride, the active ingredient in Ophtesic, is a local anesthetic presented as a sterile ophthalmic solution for ocular use. It provides topical anesthesia for diagnostic or minor surgical procedures on the eye.

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

Ophtesic, a lidocaine-based ophthalmic anesthetic, is used to provide temporary loss of sensation in ocular tissues.

- Diagnostic ocular examinations: provides anesthesia for slit‑lamp biomicroscopy, tonometry and other assessments. - Minor ocular surgery: facilitates procedures such as foreign body removal, laser treatment and small incisions. - Contact lens fitting: reduces discomfort during lens insertion and adjustment.

Ophtesic may cause a range of ocular reactions, most of which are mild and transient.

Common Side Effects: - Burning or stinging sensation at the application site. - Transient redness of the conjunctiva. - Increased tearing or lacrimation. - Temporary blurred vision. - Mild allergic conjunctivitis. - Mild corneal irritation.

Serious or Rare Side Effects: - Corneal ulceration or erosion. - Severe allergic reaction including anaphylaxis. - Persistent corneal edema leading to visual impairment. - Vision loss. - Stevens‑Johnson syndrome or toxic epidermal necrolysis. - Toxic keratitis.

When using Ophtesic, consider the following safety measures.

- Allergy assessment: avoid if known hypersensitivity to lidocaine or amide anesthetics. - Corneal integrity: do not use on eyes with active corneal disease or epithelial defects. - Ocular infection: use with caution in the presence of bacterial or viral eye infections. - Pregnancy: safety not established; use only if clearly needed after risk‑benefit evaluation. - Systemic absorption: limit application to prevent systemic toxicity, especially in children. - Store at controlled room temperature: keep in original container, protect from light and moisture.

Ophtesic may interact with other medications; awareness of potential interactions helps ensure safety.

Major Interactions (Avoid): - Systemic local anesthetics: concurrent use may increase risk of systemic toxicity. - Class I antiarrhythmics (e.g., quinidine, procainamide): additive cardiac effects. - Beta‑blockers: may potentiate bradycardia.

Moderate Interactions (Monitor Closely): - CYP3A4 inhibitors: may affect lidocaine metabolism. - Alpha‑2 agonists (e.g., clonidine): may enhance hypotensive effects. - Other ophthalmic drugs: may alter absorption or efficacy.
