Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To observe the clinical effects of insulin, compared to placebo, on hemodynamic parameters (blood pressure, heart rate and cardiac output) in states of normal and beta-blocker-induced heart rate and blood pressure suppression in healthy volunteers;Secondary Objective: To observe the effects of Insulin on clinical and biochemical measures of resting energy expenditure and metabolism (ie free fatty acids) on days with insulin compared to days with placebo. Furthermore, adverse reactions associated with insulin/placebo administration are recorded. Gastric emptying time on days with insulin compared to placebo;Primary end point(s): Change in cardiac output from baseline compared between study days;Timepoint(s) of evaluation of this end point: From baseline (T=0) to T+240 minutes. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): 1: Change in blood pressure (systolic, diastolic and mean arterial pressure in mmHg) and heart rate from baseline compared between study days 2: Effects of Insulin on stroke volume, heart rate and blood pressure parameters compared to days with placebo. 3: Percent change in plasma levels biochemical measurements (cholesterol, low density lipoprotein, high-density lipoprotein, glucose, sodium, potassium) 4: Peak plasma concentration (Cmax), time to peak plasma concentration (Tmax) and area under the plasma concentration versus time curve (AUC) of paracetamol on days with co-administration of insulin compared to days with placebo (saline). ;Timepoint(s) of evaluation of this end point: 1: From baseline (T=0) to T+240 minutes. 2: T-15, T 0, T 5, T 15, T 30, T 45, T 60, T 90, T 120, T180, T240 3: Baseline, +30, +60, +90,+120, +240 minutes. 4: Baseline (T=0), +15, +30, +45, +60, +120, +240, +255,+270,+300 minutes. | — |
