Dexchlorpheniramine is a first-generation classical antihistamine, clinically used to treat allergies. The main objective of our study was to evaluate the effects of the dexchlorpheniramine reference standard (DCPA Ref. St) and a pharmaceutical formula on DNA in human peripheral blood mononuclear cells (PBMCs). We exposed PBMCs to five different concentrations (0.5, 2.5, 5, 10, and 50 ng/mL) of DCPA Ref. St DCPA Ref. St and pharmaceutical formula in order to evaluate their cytotoxic, genotoxic, and mutagenic potential. The results showed that both dexchlorpheniramine formulations did not affect PBMC viability and CD3+, CD4+, or CD8+ lymphocyte subpopulations. The DCPA Ref. St and pharmaceutical formula neither induced genotoxic or mutagenic effects nor numerical or structural chromosomal alterations in PBMCs after 24 hours of exposure.
