Propranolol ... Yvonne and ....

[Guest guest]

Here is some information for you in regards to the beta blockers. This

first is from the Merck Manual.

B

Blockers: Symptoms and signs of hyperthyroidism due to adrenergic

stimulation may respond to -blockers. Propranolol has had the greatest use.

Phenomena that improve and that do not improve with propranolol are shown in

Table 8-4. Propranolol is not as useful for stare and lid retraction as once

thought, suggesting that both may be predominantly effects (or at least a

mixture of and effects).

Propranolol is indicated in thyroid storm (see Table 8-3). It rapidly

decreases heart rate, usually within 2 to 3 h when given orally and within

minutes when given IV. Propranolol is also indicated for the prompt

management of tachycardia found in other forms of hyperthyroidism (including

thyroiditis), and especially in older patients with no history of congestive

heart failure, since it ordinarily takes several weeks to get relief from

the antithyroid drugs. Calcium channel blockers may be useful for

controlling tachyarrhythmias in patients in whom the -blockers are

contraindicated. For details concerning propranolol therapy, see Ch. 199.

*That last part is for patients with ashma*

Here are a few medical studies also.
