Experience has been widely used in hyperthyroidism preoperative preparation and prevention of thyroid crisis. However, taking propranolol alone improves the symptoms of hyperthyroidism sometimes unsatisfied with the well-being of conventional doses, not all can prevent the crisis, the reason for the failure may be insufficient plasma content. The authors study the safety of the drug pharmacokinetics, found that patients with hyperthyroidism plasma concentration after taking a great difference. A single oral propranolol 80 mg, the control group and hyperthyroidism group, the highest plasma concentrations were large differences in the control group was 59 to 226 ng / ml; hyperthyroidism group was 54 to 211 ng / ml. The highest concentration and weight, body surface area is not the same
