1 a study is reported of the effects of phenytoin and phenobarbitone on bone calcium mobilization by parathyroid hormone in vitro.2 in a therapeutic concentration ( 15 mug/ml ) , phenytoin significantly inhibited parathyroid hormone-induced calcium release from bone.3 the inhibitory effect of phenytoin on bone calcium mobilization could play a role in the maintenance of hypocalcaemia in epileptic patients on long-term anticonvulsant drug therapy .
