To elucidate the glucocorticoid AVP feedback we monitored thirsting of 12 male volunteers without and after on or five days of prednisolone (30 mg/d). Although prednisolone suppressed pAVP below 0.2 pg/ml the rise in plasma osmolality during thirsting was not influenced by prednisolone. Independent of exogenous glucocorticoid thirsting resulted in higher urine osmolalit...
