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.
本文报道了苯妥英钠和苯巴比妥对甲状旁腺激素体外诱导骨钙动员作用的研究。
在治疗浓度(15微克/毫升)下,苯妥英钠显著抑制甲状旁腺激素诱导的骨钙释放。
苯妥英钠对骨钙动员的抑制作用可能在长期接受抗惊厥药物治疗的癫痫患者低钙血症的维持中起作用。
