Final answer:
Beta adrenergic blocking agents and anticholinergics are used to treat migraine prevention by influencing receptors associated with vasoconstriction and excessive acetylcholine.
Step-by-step explanation:
Beta adrenergic blocking agents and anticholinergics are used to treat migraine prevention.
For example, beta blockers such as metoprolol and propranolol block the β-receptors associated with vasoconstriction and cardioacceleration. By blocking these receptors, they can improve cardiac function and help prevent migraines.
Anticholinergics, like atropine, act as antagonists to muscarinic acetylcholine receptors, blocking the effects of excess acetylcholine. This can also help prevent migraines.
