摘要

Last year the Food and Drug Administration in the United States recommended that phenyl-propanolamine be removed from non-prescription and prescription medicines and that pharmaceutical companies voluntarily discontinue products containing phenylpropanolamine. This was in response to a case-control study by the Yale haemorrhagic stroke project investigators designed to determine the risk of haemorrhagic stroke in people exposed to phenylpropanolamine.
