Hypersol Ophthalmic Solution is a sterile topical preparation formulated with Phenyl Mercuric Nitrate (0.001% w/v) as an antimicrobial preservative and Sodium Chloride (5% w/v) to maintain isotonicity. This solution is intended for ophthalmic use to prevent contamination of multi-dose eye drop containers and to provide a suitable vehicle for ocular drug delivery. Phenyl Mercuric Nitrate exhibits broad-spectrum antimicrobial activity against bacteria and fungi, thereby reducing the risk of microbial growth during use. The inclusion of Sodium Chloride ensures the solution is isotonic with natural tears, minimizing ocular irritation upon instillation. Hypersol Ophthalmic Solution is indicated for use as a preservative in various ophthalmic formulations or as an adjunct in the management of ocular infections where a sterile, isotonic environment is required. It should be used with caution in patients with known hypersensitivity to mercury-containing compounds. The solution is for external use only and must not be introduced into the anterior chamber of the eye. Proper hygiene and handling are essential to avoid contamination. Patients should be advised to discontinue use and seek medical attention if signs of ocular irritation or hypersensitivity occur. Store at controlled room temperature and protect from light to maintain stability.
