Lidina

Ketotifen hydrogen fumarate, the active ingredient in Lidina, is an antihistamine (H1 receptor antagonist) and mast cell stabilizer presented as an ophthalmic solution for ocular use. It is employed to relieve eye allergy symptoms such as itching, redness, and swelling in patients with allergic conjunctivitis or seasonal allergic eye disease.

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

Lidina, an antiallergic ophthalmic agent, is indicated for ocular allergic conditions affecting the conjunctiva and cornea.

Allergic conjunctivitis: reduces itching, redness, and swelling of the eye surface. Seasonal allergic eye disease: alleviates symptoms triggered by seasonal allergens such as pollen. Allergic keratoconjunctivitis: helps control inflammation of both the cornea and conjunctiva, improving comfort and visual clarity.

Lidina may cause ocular and systemic adverse reactions, which are categorized by frequency and severity.

Common Side Effects: - Eye irritation or burning sensation: transient discomfort after instillation. - Stinging or itching: mild sensation that usually resolves quickly. - Blurred vision: temporary visual disturbance lasting minutes. - Dry eye sensation: mild dryness of the ocular surface.

Serious or Rare Side Effects: - Severe allergic reaction (anaphylaxis): rare but requires immediate medical attention. - Corneal ulcer or keratitis: persistent pain, redness, and vision changes. - Significant visual loss: sudden decrease in vision warrants urgent evaluation.

Before using Lidina, consider the following precautions to ensure safe and effective therapy.

Pregnancy: safety has not been established; consult a healthcare professional before use. Breastfeeding: unknown effect on the infant; weigh potential benefits against risks. Contact lens wearers: may experience increased discomfort; remove lenses before instillation and wait before reinserting. Concurrent ocular infections: use with caution as symptoms may be masked; monitor closely. Store below 25°C: keep in the original container, protect from light and moisture.

Lidina can interact with other ophthalmic or systemic agents; awareness of these interactions helps avoid adverse outcomes.

Major Interactions (Avoid): - Other topical antihistamines: additive ocular irritation may occur. - Systemic antihistamines: combined use can increase sedation or systemic antihistaminic effects.

Moderate Interactions (Monitor Closely): - Beta‑blocker eye drops: may enhance ocular hypotensive effects, requiring monitoring of intra‑ocular pressure. - Non‑steroidal anti‑inflammatory eye drops: possible reduction in anti‑inflammatory efficacy. - Anticholinergic eye drops: may increase ocular dryness when used together.
