Comparison of the immunoreactive plasma corticotropin and cortisol responses to two synthetic corticotropin preparations (tetracosactrin and cosyntropin) in healthy cats.

Plasma cortisol and immunoreactive (IR)-ACTH responses to 125 micrograms of tetracosactrin and cosyntropin--the formulation of synthetic ACTH available in Europe and the United States, respectively--were compared in 10 clinically normal cats. After administration of tetracosactrin or cosyntropin, mean plasma cortisol concentration reached a peak and plateaued between 60 and 120 minutes, then gradually decreased to values not significantly different from baseline concentration by 5 hours. Mean plasma IR-ACTH concentration reached a maximal value at 15 minutes after administration of tetracosactrin or cosyntropin and was still higher than baseline concentration at 6 hours. Difference between mean plasma cortisol and IR-ACTH concentrations for the tetracosactrin or cosyntropin trials was not significant at any of the sample collection times. Individual cats had some variation in the time of peak cortisol response after administration of either ACTH preparation. About half the cats had peak cortisol concentration at 60 to 90 minutes, whereas the remainder had the peak response at 2 to 4 hours. In general, however, peak cortisol concentration in the cats with delayed response was not much higher than the cortisol concentration at 60 to 90 minutes. Overall, these results indicate that tetracosactrin or cosyntropin induce a comparable, if not identical, pattern of adrenocortical responses when administered to healthy cats.
