Description

Overview of the medicine

Allet 0.1% Eye Drop (Olopatadine) is an ophthalmic solution used to relieve ocular itching associated with allergic conjunctivitis.

Uses & Indications

Ocular itching associated with allergic conjunctivitis

Seasonal allergic conjunctivitis

Dosage

Adults

One drop in each affected eye twice daily, approximately 6 to 8 hours apart.

Elderly

Same as adult dosage; no specific adjustment needed.

Renal_impairment

No dosage adjustment necessary due to minimal systemic absorption.

How to Take

For ocular use only. Instill drops into the conjunctival sac. Avoid touching the dropper tip to any surface to prevent contamination.

Mechanism of Action

Olopatadine is a selective H1-receptor antagonist and mast cell stabilizer. It prevents histamine release from mast cells and blocks histamine's effects on H1-receptors, thereby reducing itching and other allergic symptoms.

Pharmacokinetics

Onset

Rapid, within minutes of application.

Excretion

Mainly via renal excretion as unchanged drug after systemic absorption.

Half life

Approximately 3 hours (systemic, though ocular effect is localized).

Absorption

Minimal systemic absorption after topical ocular administration.

Metabolism

Minimal metabolism in the eye. Primarily excreted unchanged.

Side Effects

Contraindications

Hypersensitivity to olopatadine or any component of the formulation.

Drug Interactions

Other Ophthalmic Medications

If more than one topical ophthalmic drug is used, the drugs should be administered at least 5 minutes apart.

Storage

Store at room temperature (below 30°C), protected from light. Do not freeze.

Overdose

Ocular overdose is unlikely to cause systemic toxicity due to limited absorption. In case of accidental ingestion, symptomatic treatment may be necessary.

Pregnancy & Lactation

Pregnancy Category C. Use during pregnancy only if the potential benefit justifies the potential risk to the fetus. Caution advised during lactation as it is unknown if olopatadine is excreted in human milk.
