Stimulation of residual insulin secretion by glibenclamide in insulin dependent diabetics

Abstract
Residual insulin secretion, reflected by the presence of C-peptide in serum and urine, was demonstrated in 5 of 10 insulin-requiring diabetics of less than 10 yr duration tested. The C-peptide response, in the C-peptide secretors, showed a significant increase in both serum and urine after 4 wk treatment with 15 mg glibenclamide daily in addition of their usual insulin regime although no beneficial effects in metabolic control were detected. Glibenclamide might be a useful adjunct to insulin therapy in insulin-requiring diabetics who still secrete C-peptide.
