| 描述 | 二氢速心律失常是维生素D的合成类似物。二氢速心律失常可用于研究低钙血症(血液中缺乏钙)和甲状旁腺功能减退(体内缺乏甲状旁腺激素)[1][2]。 |

| 相关类别 | |
| 体外研究 | 在缺乏甲状旁腺激素和功能性肾组织的情况下,二氢速调素通过刺激肠道钙吸收和动员骨钙而有效地提高血钙[1]。二氢速调甾醇也会增加肾磷酸盐排泄[1]。 |
| 体内研究 | 二氢速调甾醇是一种有效的合成维生素D类似物,可广泛获得,但比维生素D2更昂贵。它的起效期和半衰期介于维生素D2和骨化三醇之间。二氢速调素(最初以0.03至0.08 mg/kg/天的剂量给药,持续2至3天。最终剂量范围为0.004至0.04 mg/kg/天)对甲状旁腺机能减退症的治疗有用[2]。动物模型：动物模型：五只混合饲养的中青年猫[2]剂量：最初剂量为0.03至0.08 mg/kg/天,持续2至3天。最终剂量范围为0.004至0.04 mg/kg/天。给药：口服给药结果：有助于治疗甲状旁腺功能减退症。 |
