[Pharmacokinetics of beta blockers in hyperthyroidism. Therapeutic relevance]

Hyperthyroidism is associated with alterations in pharmacokinetic parameters such as absorption, distribution, metabolism and elimination. Beta-blockers are used in particular in the treatment of hyperthyroidism and are also subject to pharmacokinetic changes occurring during this pathology. The magnitude of these variations is examined when beta-blockers are used for clinical manifestations of hyperthyroidism or during thyroid surgery. Clinical means used to assess the accuracy of therapeutic drug monitoring are also described.
