| Abstract: | Acetohexamide hypoglycemia in a patient with renal failure has been successfully treated by peritoneal dialysis. Peritoneal dialysis was done in such a patient, and specimens of serum were collected to measure levels of acetohexamide and its main active metabolite, hydroxyhexamide. During dialysis, hypoglycemia was corrected. After 17 1/2 hours of dialysis, serum acetohexamide level was essentially unchanged. Serum hydroxyhexamide level had decreased at a slower rate than the rate of decrease previously measured in a uremic patient not on dialysis. Although peritoneal dialysis may correct the hypoglycemia, the data suggest that acetohexamide and hydroxyhexamide are not dialyzable. Due to these problems this drug should not be used in patients with chronic renal failure. The drug of choice to control hyperglycemia in patients with renal insufficiency is insulin. If for any reason insulin cannot be used, tolbutamide is the oral hypoglycemic agent of choice. |
