Data from PEM studies completed since 1984 on the prescribing patterns of 27 new drugs indicated an overall response rate of only 530', in terms of useful postmarketing information. Data also indicated that physicians who were heavy prescribers of new drugs were less likely to respond to PEM requests for postmarketing information on adverse reactions.
