BUFFERING Numerous drugs, notably alkaloidal salts, are handiest at pH stages that favor the undissociated free of charge bases. At such pH degrees, even so, the drug might be unstable to make sure that compromise stages should be observed and held by way of buffers. A person function of buffering some ophthalmic options is to forestall an increase in pH due to the gradual release of hydroxyl ions by glass. These kinds of an increase in pH can impact the two the solubility and the stability with the drug. The decision if buffering agents should be included in making ready an ophthalmic Remedy must be based on many considerations. Usual tears have a pH of about 7.4 and possess some buffer capability. The appliance of an answer to the eye stimulates the move of tears and also the speedy neutralization of any surplus hydrogen or hydroxyl ions in the buffer ability with the tears.
