Beta-adrenergic-blocking medications have been hypothesized to benefit persons with a wide variety of neuropsychiatric disorders. Research supports their use in only three areas, however: anxiety disorders with prominent physiological signs, impulsive aggression, and neuroleptic-induced akathisia (NIA). Except for NIA, beta blockers are best used adjunctively, and cannot be considered treatments of choice as monotherapy. These guidelines are applicable to individuals with intellectual disability and psychiatric illness as well, and beta blockers are generally effective and well tolerated in these persons. Nadolol, a hydrophilic beta blocker, may be preferable for anxiety, whereas propranolol and metoprolol (lipophilic) are more beneficial in treating aggression and NIA.1999 Wiley-Liss, Inc.MRDD Research Reviews 1999;5:290-298.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
