One particular objective of buffering some ophthalmic methods is to avoid a rise in pH due to the gradual release of hydroxyl ions by glass. Such an increase in pH can influence both the solubility and The soundness with the drug. The decision whether or not buffering agents really should be added in getting ready an ophthalmic Option should be determined by several factors.
