title: Synergistic effect on insulin secretion from INS-1 cells of a sulfonylurea and a phosphodiesterase 3 inhibitor.
abstract: The effects on insulin secretion from INS-1 cells of varying concentrations of the sulfonylurea glyburide and the PDE3 inhibitor milrinone, separately and in combination were measured. Over a range of concentrations the effects of the two drugs in combination were more than additive. A response surface model was fit to the data and was found to describe the data well. From this model, it was apparent that a significant synergistic effect upon insulin secretion existed over a wide range of combinations of the two drugs.
