“…140a The antispastic efficacy of phenytoin was evaluated in a controlled trial in patients with a variety of diagnoses. 141 Six of 10 patients had tone reduction from phenytoin at serum levels greater than 7 µg/mL, but with no doseresponse relationship beyond this threshold.The bothersome side effects of this drug are well known and it is unclear whether there is a patient population (apart from those already treated by phenytoin for associated epilepsy) that may benefit more from phenytoin than from more modern antispastic agents with less serious side effects. 5…”
“…The antispastic effect of chlorpromazine and some of its derivates has been clearly established in controlled studies [141][142][143][144] and may be related to alpha-adrenergic blockade (see above). Sedation was consistently a significant problem.…”

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.
