| 体外研究 | Pizotifen是一种有效的5-HT2受体拮抗剂,对5-HT1C结合位点具有高亲和力[1]。 Pizotifen是一种抗过敏的5-HT2A受体拮抗剂,具有抑制5-羟色胺增强的ADP诱导的血小板聚集的能力[2]。 |
| 体内研究 | 所有给药剂量的Pipethiadene和Pizotifen都显着降低了胎儿的体重;在0.6和1.2 mg/kg Pipethiadene之后,并且仅在中等剂量的Pizotifen之后,胎盘的重量显着减少。植入,活体,死胎,再吸收以及外部,骨骼和内脏异常的发生方式与对照组没有差异。处理小鼠的骨髓细胞中的染色体畸变数与阴性对照组没有显着差异。与对照组相比,微核试验显示微核的频率没有升高。在两种较高剂量的Pipethiadene和Pizotifen马来酸盐后,有丝分裂指数低于对照组[3]。 |

Skin protection Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique (without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it. Body Protection Complete suit protecting against chemicals, The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace. Respiratory protection Where risk assessment shows air-purifying respirators are appropriate use a full-face particle respirator type N100 (US) or type P3 (EN 143) respirator cartridges as a backup to engineering controls. If the respirator is the sole means of protection, use a full-face supplied air respirator. Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU). Section9.
