| Abstract | This paper presents 14 cases in which the distribution of barbiturates and the hydroxylated metabolites in combination with miscellaneous CNS-active drugs was studied. In 7 of these cases the other drug present was methadone, and in the remainder dihydrocodeine, morphine, propoxyphene, amitriptyline, meprobamate, cyclizine and dipipanone, diphenhydramine and methaqualine. Amitriptyline, methadone, cyclizine and dipipanone, methaqualone and diphenhydramine appeared to modify the distribution of amylorbarbitone and quinalbarbitone. Likewise, the barbituates seemed to alter the distribution of amitriptyline, propoxyphene and, in one instance, methadone. |
