Effects of beta‐adrenoceptor blockade on carbohydrate metabolism during exercise‐comparison of pindolol and metoprolol.

1 The influence of equipotent cardiac beta-adrenoceptor blocking doses of pindolol (10 mg daily) and metoprolol (200 mg daily) was studied in ten healthy male subjects. 2 The subjects were studied at rest and during exercise before and after 3 days' treatment with pindolol or metoprolol. 3 At rest and during exercise, there were no significant differences in the blood glucose levels between the metoprolol and pindolol treatments when compared with control values.
