Triprolidine hydrochloride was fed to groups of 60 B6C3F1 mice per sex at dietary levels of 0, 500, 2000, or 4000 ppm (as the free base) for up to 2 years. Up to 12 mice of each sex and dose group were terminated after 65 weeks for hematology and clinical chemistry. The control and high-dose groups were examined histologically. A complete histopathological examination was performed on the remaining 48 mice from each dose group when removed from study due to moribund condition, early death, or terminal euthanization at 105 weeks. Triprolidine did not significantly alter the survival of either sex. High-dose male and mid- and high-dose female body weights were significantly less than controls at the end of the study. Significant trends toward lower frequency with increasing dose were noted in females for fatty change in the liver and lymphomas (combination of lymphocytic, mixed, and histiocytic lymphomas). Similar negative trends in males were for lymphocytic cellular infiltration in multiple organs and lung alveolar/bronchiolar adenomas or the combination of alveolar/bronchiolar adenomas or carcinomas. Significant trends toward increased frequency with increasing dose were found in female mice for lymphocytic infiltration in multiple organs and cytoplasmic alterations of the acinar cells of the parotid gland. Similar positive trends were found in males for cytoplasmic alterations of the parotid gland and various hepatocellular changes (e.g., hypertrophy and altered foci). While there was a positive dose response trend for hepatocellular adenomas in males the combination of these and hepatocellular carcinomas eliminated the significant trend, and it was concluded that there was no evidence of a carcinogenic response to triprolidine in B6C3F1 mice.(ABSTRACT TRUNCATED AT 250 WORDS)
