The Alimentary Absorption of Some Enteric-Coated Sodium and Potassium Chloride Tablets

Abstract

The alimentary absorption of sodium chloride and potassium chloride tablets covered with a new enteric coating, has shown their absorption to be satisfactory. Of three other brands, one has been found to be only poorly absorbed, producing diarrhoea in some subjects; a second brand was poorly absorbed in 1 out of 5 patients, while the third proved moderately satisfactory. Samples of all the brands of enteric‐coated tablets passed the in vitro tests for disintegration specified by the British Pharmacopoeia (1958, Appendix 21B).
