Zaditen Eye Drop contains Ketotifen 0.25 mg as its active ingredient, a potent antihistamine and mast cell stabilizer used primarily in the management of allergic conjunctivitis. Ketotifen exerts its therapeutic effect by inhibiting the release of histamine and other inflammatory mediators from mast cells, thereby alleviating symptoms such as itching, redness, and swelling of the eyes associated with allergic reactions. This ophthalmic solution is indicated for the treatment and prevention of ocular itching caused by allergic conjunctivitis. Zaditen Eye Drop is typically administered as one drop in the affected eye(s) twice daily, or as directed by a healthcare professional. It is well tolerated, with minimal systemic absorption, reducing the risk of systemic side effects. Common adverse reactions may include mild eye irritation, burning, or stinging upon instillation, which are usually transient. Patients should avoid contact lens use during treatment unless advised otherwise by a physician. Zaditen Eye Drop should be used with caution in individuals with hypersensitivity to ketotifen or any of the formulation excipients. Proper administration and adherence to prescribed dosage are essential to achieve optimal therapeutic outcomes in managing allergic ocular conditions.
