奥美拉唑对利培酮和9-羟利培酮血药浓度影响的研究

目的：观察奥美拉唑对利培酮和9-羟利培酮血药浓度的影响。方法20例精神分裂症合并胃溃疡患者,给予利培酮联合奥美拉唑治疗1周。检测奥美拉唑治疗后利培酮以及9-羟利培酮血药浓度。结果未使用奥美拉唑前,利培酮与9-羟利培酮血药浓度为（29.25±7.82）μg/L；使用奥美拉唑后,利培酮与9-羟利培酮血药浓度为（37.15±11.68）μg/L,差异有统计学意义（P〈0.05）。结论奥美拉唑能够提高利培酮与9-羟利培酮血药浓度,因此,临床上治疗精神分裂症合并胃溃疡患者,给予奥美拉唑联合利培酮治疗时,应该监测患者利培酮与9-羟利培酮血药浓度,及时对药物剂量进行调整。

Influence study of omeprazole on blood drug concentration of risperidone and 9-hydroxy risperidone

Objective To observe the influence of omeprazole on blood drug concentration of risperidone and 9-hydroxy risperidone. Methods A total of 20 schizophrenia with gastric ulcer cases were treated by risperidone combined with omeprazole for 1 week. Detections of blood drug concentration of risperidone and 9-hydroxy risperidone were made after the omeprazole treatment. Results Before application of omeprazole, blood drug concentration of risperidone and 9-hydroxy risperidone was （29.25±7.82）μg/L. After using omeprazole, blood drug concentration of risperidone and 9-hydroxy risperidone was （37.15±11.68） μg/L. The difference had statistical significance （P〈0.05）. Conclusion Omeprazole can increase the blood drug concentration of risperidone and 9-hydroxy risperidone, which should be monitored in the risperidone combined with omeprazole treatment of schizophrenia with gastric ulcer, and timely adjustment of drug dose is necessary.
