作者在45-83岁的门诊精神病患者中测量了至少1个月的氟哌啶醇(HL)血清水平。从患有精神分裂症(n = 23)或阿尔茨海默病(AD)(n = 9)的32名患者收集血液。精神分裂症患者(中位年龄59岁)的HL日剂量高于AD患者(中位年龄80岁)(P < 0.0005),但未观察到HL血清浓度的显著组间差异。在总样本中,年龄与HL剂量呈负相关(P < 0.001),与血清HL水平/剂量比值呈正相关(P < 0.05)。老年AD患者的HL水平/剂量比值高于青年精神分裂症患者(P < 0.005)。血清HL水平远低于年轻精神分裂症患者,但与老年AD患者报告的水平相当。年龄相关和疾病相关的药代动力学和药效学变化可能会减少老年患者对更高剂量的精神抑制剂的需求以及更高的血药浓度。
The authors measured serum levels of haloperidol (HL) in outpatients ages 45-83 years with psychosis treated with HL for at least 1 month. Blood was collected from 32 patients with either schizophrenia (n = 23) or Alzheimer's disease (AD) (n = 9). HL daily dose was greater in patients with schizophrenia (median age, 59) than in AD patients (median age, 80) (P < 0.0005), but no significant group differences in HL serum concentrations were observed. In the total sample, age correlated negatively with HL dose (P < 0.001) and positively with the ratio of serum HL level/dose (P < 0.05). The ratio of HL level/dose was higher in the elderly AD patients than in younger subjects with schizophrenia (P < 0.005). Serum HL levels were much lower than those reported in younger schizophrenia patients, but comparable to those reported in elderly patients with AD. Aging-related and disease-associated pharmacokinetic and pharmacodynamic changes may reduce the need for higher neuroleptic doses as well as higher blood levels in older patients.
