Paracetamol (PCM) and acetylsalicylic acid (ASA), both widely used analgesics, were tested for their clastogenicity in V79 cells in vitro. Rat liver S9 mix and primary rat hepatocytes (PRH) were used as external activation systems. ASA was found to be negative with and without activation system in concentrations up to 10(-2) M. In contrast PCM induced concentration-dependent chromosomal aberrations with and without activation system within the range of 3 x 10(-3) and 10(-2) M. The greatest effects were observed following continuous treatment with PRH activation and without external metabolization. Pulse treatments without external metabolization, with S9 mix and PRH were less effective. The clastogenic potency of PCM seems to be partly independent of metabolic activation. Although clastogenic effects in vitro were observed only in very high concentrations pharmacokinetic data and other published mutagenicity data indicate that there might be a risk for human use. Peak plasma levels of more than 10(-4) M have been reported (Forrest et al., 1982) and 2 groups of investigators (Kocisova et al., 1988; Hongslo et al., 1990) found PCM to be weakly clastogenic in human lymphocytes in vivo in the maximum human therapeutic dose range.
