In vitro Sodium Picosulfate对培养的肝细胞表现出细胞毒性作用。在兔子迅速生长的培养肝细胞中,800和1600 mg/mL的剂量依赖性诱导真空和脂肪变化以及坏死,同时伴有有丝分裂活动降低和LDH值轻微增加。在4天大的大鼠肝细胞培养中观察到类似但较轻的效应,而培养6至11天的肝细胞能够耐受1600 mg/mL Sodium Picosulfate。在人类肝细胞培养中,800和1600 mg/mL剂量的细胞数量略有下降,核分裂数目随剂量减少。[1]
In vivo 长期使用Sodium Picosulphate不影响大鼠结肠的神经肽含量。在6个月的研究期间,每天给予10 mg/kg的剂量或每周两次给予7.5 mg/kg的剂量,Sodium Picosulphate不会改变粘膜、黏膜下层或肌肉外层中血管活性肠肽(VIP)、生长抑素和P物质的水平。[2] Sodium Picosulphate对回肠和结肠上皮细胞的增殖没有主要影响。在为期12周的研究中,连续治疗10 mg/kg Sodium Picosulphate不会影响回肠的Brdu标记指数(LI),和对照组比较,也没有引起LI的统计学显著性增加。治疗期间,随着Sodium Picosulphate的处理,隐窝沿线的增殖模式保持不变。[3] 长期治疗下,Sodium Picosulphate不会诱导大鼠结肠运动性的慢性变化。预处理23周的10 mg/kg/day Sodium Picosulphate不会在空腹状态或进食3克餐后引起与短暂收缩相关的长峰爆发(LSB)持续时间或LSB频率的任何显著变化。[4]
