“…Although acetazolamide is rather a specific carbonic anhydrase inhibitor, it can affect sodium secretion indirectly, perhaps by changing the intracellular pH (Slegers & Moons, 1968). Furthermore, there have been suggestions (Parsons, 1956;Kinney & Code, 1964;Kitahara, & Imamura, 1966) that acetazolamide may inhibit chloride transport by mechanisms other than interference with carbonic anhydrase. Kitahara, Fox & Hogben (1967) have offered proof of this supposition by demonstrating that active chloride transport across frog cornea can be inhibited by acetazolamide, despite the complete absence of carbonic anhydrase in this tissue.…”

Active buffer transport, e.g. H+ -secretion by stomach and kidney and HCO3--secretion by pancreas and salivary glands, is linked with the presence of a HCO3-stimulated ATP-Phosphohydrolase. In contrast to (Na+ -k+)-ATPase which is considered to be equivalent to the Na+ pump, the HCO3--ATPase requires only one ion for activation and is insensitive to ouabain. The HCO3--ATPase is found in the plasma membrane of the epithelia, but in contrast to the (Na+ -k+)-ATPase it is located in the luminal cell border. The activity of the HCO3--ATPase changes in parallel along with the rate of active buffer transport, a finding which underlines its importance as a transport enzyme. Several disorders of buffer transport are described which are possibly associated with a defect of the HCO3--ATPase system.
