Abstract
Abstract Drugs, nutrients and other solutes are administered to fixed and mobile tissue cells of the mammal in an aqueous solution containing about 75-200 mM/L of Na , about 7-75 mM/L K , about 12-28 mM/L HCO3 , about 70-195 mM/L Cl and preferably containing about 3-8 mM/L Mg and about 3-8 mM/L HPO4 and/or SO4 , and/or acetate, and/or gluconate ; the solution having a pH of about 7.4 to 8.4 and an osmolality of about 170-460, preferably about 260-340, more preferably about 290-310, and most preferably 300 milliosmols per liter. The composition can contain other additives, e.g. stabilizing agents, and the solutes to be carried, e.g., antibiotics, vitamins, nutrients, and other solutes.
