The authors evaluate treatment by a combination of insulin and gliquidone (Glurenorm) in 29 type 2 diabetics where long-term treatment with oral antidiabetics alone had failed. Within four months all patients were completely compensated from the metabolic aspect. HbA1c declined from 10.8 to 6.5, C peptide, on the other hand, increased from the original value of 1.2 ng/ml to 1.8 ng/ml. The authors did not observe any undesirable effects or hypoglycaemic states. Gliquidone is suitable for combined treatment because of its short-term effect; stimulation of endogenous secretion has a pulsed character and imitates an intensified regime. The prerequisite of success is a low dose of intermediary insulin to prevent inhibition of the central action of gliquidone.
