These kinds of a rise in pH can affect both of those the solubility and the stability in the drug. The choice whether buffering agents should be included in making ready an ophthalmic Resolution should be based on many concerns. Usual tears Possess a pH of about seven.4 and possess some buffer ability. The application of a solution to the eye stimulates the move click here of tears plus the fast neutralization of any extra hydrogen or hydroxyl ions in the buffer potential of the tears.
