Abstract Phenytoin, at a concentration which is known to inhibit parathyroid extract-induced bone resorptionin vitro, has been shown to have no significant effect on either the cyclic AMP content of four-day-old mouse calvaria which had been in tissue culture for 48 h or on the increase in cyclic AMP content occurring after the addition of parathyroid extract to the medium. Phenytoin has also been shown to be an effective inhibitor of bone resorptionin vitro induced by 25-hydroxycholecalciferol. These observations suggest that the inhibitory effect of phenytoin on parathyroid extract and hormone-induced bone resorption takes place beyond the cyclic AMP stage.
