Ergotamine and cerebral blood flow

Abstract

We measured the cerebral blood flow (CBF) of 16 patients by the xenon-133 intracarotid method before and after the intramuscular injection of ergotamine tart rate. The regional and hemispheric CBF was unaltered, even in 3 migraneurs in whom ergotamine relieved the headache. Ergotamine tartrate in therapeutic doses has no effect on the cerebral circulation. © 1978 American Heart Association, Inc.
