A person purpose of buffering some ophthalmic answers is to stop an increase in pH a result of the sluggish release of hydroxyl ions by glass. These types of a rise in pH can have an impact on both of those the solubility and the stability in the drug. The decision if buffering agents need to be additional in getting ready an ophthalmic Resolution must be based on various considerations. Ordinary tears Use a pH of about 7.4 and have some buffer capacity.
