[The study of developmental pharmacology (I). Effect of pentazocine HCl on the physiology of rats given the drug during perinatal and postnatal periods (author's transl)].
The effects of drug administration on the dams (F0) and their offspring (F1), particularly on the central nervous and reproductive functions of F1, were studied by oral administration of pentazocine HCl to rats during the perinatal and postnatal periods. No significant differences were observed between administered and control rats regarding body weight changes and food intake during perinatal and postnatal periods in F0 at all dosages, but temporary salivation was observed in the 200 and 100 mg/kg groups, and decline of spontaneous activity and respiratory rate, disappearance of righting reflex, clonic convulsion were observed in some of the 200 mg/kg group. No significant differences were observed regarding litter size, birth rate, state and timing of differentiation as postnatal development, sex maturity, reproductive function in F1, although some groups were slightly inferior in body weight at birth and during the nursing period. Furthermore, no differences were observed in respect to the nervous functions of balance, exercise and psychotic related activity in the open-field test.
