Final answer:
Sympatholytic drugs are used to suppress sympathetic symptoms in hyperthyroidism. ß-blockers, specifically those that block the ß-receptors associated with vasoconstriction and cardioacceleration, are commonly used for this purpose. Another example is clonidine, an α-agonist.
Step-by-step explanation:
Sympatholytic drugs are a class of drugs that suppress sympathetic symptoms in hyperthyroidism. These drugs work by antagonizing the adrenergic receptors, blocking the binding of norepinephrine or epinephrine to these receptors. By doing so, they reduce the effect of sympathetic activation in the body.
One of the most commonly used sympatholytic drugs are ß-blockers, specifically those that block the ß-receptors associated with vasoconstriction and cardioacceleration. These drugs, such as metoprolol and propanolol, can improve cardiac function by allowing blood vessels to dilate and keeping heart rate from increasing.
Another example of a sympatholytic drug that is used for other treatments aside from hypertension and anxiety is clonidine, which is an α-agonist. It acts by blocking sympathetic activity and suppressing the sympathetic influence on the target organ.
