USAGE NOTE: A salt form of a drug consists of 2 parts, one acidic and one basic group that are readily disassociated in liquid phase. Salt forms are either salts of strong acids and basic drugs (e.g. Atropine Sulfate, Cetirizine Hydrochloride) or salts of strong bases and acidic drugs (Allopurinol Sodium). This association is usually used in conjunction with Has_Free_Acid_Or_Base_Form.
