Abstract
Abstract The phenothiazine psychotherapeutant, triflupromazine (TFP), was studied for mutagenic potential in dominant-lethal, in vivo and in vitro cytogenetic and host-mediated assay procedures. No evidence of gross chromosomal aberrations or point mutations was detected in these assays even at dosage regimens which produced substantial lethality. The effect of the drug on body temperature was measured at the same doses used for mutagenicity testing. A marked and sustained temperature reduction occurs shortly after administration of as little as 10 mg/kg. Due to the pronounced physiological effects at these levels, the validity of mutagenicity studies conducted at the same levels may be seriously questioned.
