Theophylline and chlorpromazine to elicit MER???? Heavens to mergatroyd! As far as I know, theophylline is primarily an anti-asthmatic drug. I know from personal experience with one child that it can really jazz a kid up. It is chemically related to caffeine. Chlorpromazine is a psychotropic drug given as a "sedative" to psychotics and manic-depressives in the manic phase. This is something that you would take to elicit MER? I don't think so (at least, I hope not!). Sorry for this unprofessional response, but I got carried away. Judy K. in Israel
