    The effects and plasma concentrations of different doses of propranolol and metoprolol were studied in 34 hyperthyroid patients. The initial daily doses were propranolol 160 mg or metoprolol 200 mg. If the resting heart rate remained above 75 beats per min after treatment for 4–7 days, the dose was increased and the patient re-examined after a further 4–7 days. Propranolol (n=17) caused a reduced heart rate, a decrease in serum 3,3′,5-triiodothyronine (T3) and an increase in serum 3,3′,5′-triiodothyronine (reverse T3, r T3). In 10 patients, there was no change in T3 or r T3 until the daily dose of propranolol had been increased to 240 or 320 mg. The plasma level of propranolol was significantly correlated with the decrease in T3 and the increase in r T3. Metoprolol (n=17) caused a reduction in heart rate similar to that following propranolol.
