Propranolol 55-66 orosomucoid 1 Rattus norvegicus 11-36 2539818-1 1989 Alpha-1-acid glycoprotein (AAG), 750 mg/kg, was administered to rats to determine its effect on propranolol binding and beta blockade. Propranolol 96-107 orosomucoid 1 Rattus norvegicus 0-25 2539818-4 1989 AAG treatment significantly increased the heart rate response to isoproterenol, compared to albumin (95.4 +/- 19.6 vs 28.3 +/- 16.7% of baseline value, measured 45 min after propranolol, P less than 0.001). Propranolol 174-185 orosomucoid 1 Rattus norvegicus 0-3 2539818-5 1989 AAG-treated rats had greater [3H]propranolol binding in serum (93.0 +/- 3.2 vs 76.7 +/- 3.0%, P less than 0.01) and a lower calculated unbound [3H]propranolol concentration in serum (2.7 +/- 1.3 vs 7.4 +/- 3.1 X 10(6) dpm/ml, P less than 0.001) than albumin-treated rats. Propranolol 33-44 orosomucoid 1 Rattus norvegicus 0-3 2539818-5 1989 AAG-treated rats had greater [3H]propranolol binding in serum (93.0 +/- 3.2 vs 76.7 +/- 3.0%, P less than 0.01) and a lower calculated unbound [3H]propranolol concentration in serum (2.7 +/- 1.3 vs 7.4 +/- 3.1 X 10(6) dpm/ml, P less than 0.001) than albumin-treated rats. Propranolol 147-158 orosomucoid 1 Rattus norvegicus 0-3 2539818-6 1989 These data demonstrate that AAG can alter propranolol pharmacokinetics and pharmacodynamics even when administered after the propranolol effect is evident. Propranolol 42-53 orosomucoid 1 Rattus norvegicus 28-31 2539818-6 1989 These data demonstrate that AAG can alter propranolol pharmacokinetics and pharmacodynamics even when administered after the propranolol effect is evident. Propranolol 125-136 orosomucoid 1 Rattus norvegicus 28-31 2539818-7 1989 Because the reported affinity of propranolol for cardiac beta receptors is 10,000 times greater than its affinity for AAG, these data suggest that AAG acted by altering propranolol disposition rather than by directly competing with beta receptors for drug. Propranolol 33-44 orosomucoid 1 Rattus norvegicus 147-150 2539818-7 1989 Because the reported affinity of propranolol for cardiac beta receptors is 10,000 times greater than its affinity for AAG, these data suggest that AAG acted by altering propranolol disposition rather than by directly competing with beta receptors for drug. Propranolol 169-180 orosomucoid 1 Rattus norvegicus 147-150
