One reason of buffering some ophthalmic options is to avoid an increase in pH brought on by the sluggish launch of hydroxyl ions by glass. This sort check here of an increase in pH can impact both of those the solubility and The steadiness on the drug. The decision whether buffering brokers should be additional in planning an ophthalmic Option have to be determined by various factors. Ordinary tears Use a pH of about 7.four and have some buffer capability. The application of an answer to the eye stimulates the move of tears as well as immediate neutralization of any excess hydrogen or hydroxyl ions within the buffer potential of the tears. Many ophthalmic drugs, like alkaloidal salts, are weakly acidic and possess only weak here buffer potential.
