A person goal of buffering some ophthalmic methods is to avoid an increase in pH a result of the gradual release of hydroxyl ions by glass. These kinds of an increase in pH can have an effect on both equally the solubility and the stability in the drug. The choice if buffering brokers should be additional in getting ready an ophthalmic Option need to be based on a number of things to consider.
