摘要

1.1. 对7例内源性抑郁症患者给予2×1 mg/kg/天地西帕明(DMI)治疗21天,观察其临床疗效与血浆水平的相关性。临床反应通过汉密尔顿抑郁评定量表(HDRS)得分的降低来衡量。在研究的7名患者中,有5名患者看到了DMI的有益效果,并且在治疗开始一周后就完全明显了。在单次给药后和“稳定状态”下,DMI血浆水平在个体间都存在很大差异。单次给药后的最大血浆浓度(Cmax)在19至179 ng/ml之间,平均“稳态”浓度在65至240 ng/ml之间。HDRS评分与血浆DMI水平无显著相关性;然而,在治疗结束时(第22天)的血浆水平和改善评分显示出曲线关系。4例患者DMI计算“稳态”后血浆消失半衰期为11.5 ~ 34.3小时(平均±S.E.M. = 26.2±5.0)。

Clinical response, plasma levels and pharmacokinetics of desiramine in depressed in-patients

  • 1.

    1. Correlation between clinical response and plasma levels was investigated in seven patients with endogenous depression treated with 2×1 mg/kg/day of desipramine (DMI) for 21 days. Clinical response was measured by reduction in Hamilton Depression Rating Scale (HDRS) scores.

  • 2.

    2. A beneficial effect of DMI was seen in five out of seven patients studied and was fully evident already one week after the beginning of treatment.

  • 3.

    3. Great inter-individual differences were observed in DMI plasma levels both after a single dose and at ‘steady state’. The maximum plasma concentration after a single dose (Cmax) ranged between 19 and 179 ng/ml and the mean ‘steady state’ concentration between 65 and 240 ng/ml.

  • 4.

    4. No significant correlation was found between HDRS scores and plasma levels of DMI; however, a plot of plasma levels and amelioration scores at the end (22nd day) of treatment was suggestive of a curvilinear relationship.

  • 5.

    5. Post ‘steady state’ plasma disappearance half-lives of DMI calculation in four patients ranged from 11.5 to 34.3 hr (mean ± S.E.M. = 26.2 ± 5.0).
