How Does Sodium Bicarbonate Increased Urine pH

Sodium bicarbonate also increases urinary pH (15), which may influence the rate of excretion of etorphine in the urine. Basic drugs, such as etorphine, are less likely to transfer into an alkaline urine and will preferentially remain in a more acidic solution (2).

How does sodium bicarbonate affect urine?

Sodium bicarbonate produced a significant metabolic alkalosis and an increase in urine pH. Both sodium bicarbonate and sodium chloride produced a profound diuresis.

How does sodium bicarbonate affect pH?

Sodium Bicarbonate is the monosodium salt of carbonic acid with alkalinizing and electrolyte replacement properties. Upon dissociation, sodium bicarbonate forms sodium and bicarbonate ions. Ion formation increases plasma bicarbonate and buffers excess hydrogen ion concentration, resulting in raised blood pH.
