title: Effect of enalapril on handling of a sodium chloride load by genetically hypertensive and normotensive rats.
abstract: 1. Enalapril was given in the drinking water (300 mg/L) for 4.5 days to normotensive (N) and genetically hypertensive (GH) rats on zero sodium intake. An intraperitoneal NaCl load was given 12 h after enalapril was started. 2. Enalapril did not increase the maximum rate of sodium excretion, but caused the rats to excrete more than the load in the first 24 h and then to have a slow fall in body sodium while on a sodium-free diet. 3. In terms of the Strauss et al. (1958) concept of body sodium, enalapril appears to lower the basal level. However, in addition it causes a slow leak of sodium which becomes apparent when sodium intake is very low.
