BUFFERING Many medications, notably alkaloidal salts, are handiest at pH concentrations that favor the undissociated free of charge bases. At these types of pH ranges, having said that, the drug could be unstable to make sure that compromise amounts need to be identified and held by way of buffers. One reason of buffering some ophthalmic methods is to stop an increase in pH caused by the gradual release of hydroxyl ions by glass. This sort of an increase in pH can have an effect on equally the solubility and The soundness in the drug. The decision whether buffering brokers should be extra in preparing an ophthalmic Answer has to be dependant on several factors. Ordinary tears Have got a pH of about 7.4 and have some buffer potential. The appliance of an answer to the eye stimulates the circulation of tears as well as the immediate neutralization of any extra hydrogen or hydroxyl ions within the buffer ability of the tears.
