Long-term low-dosage dependence on benzodiazepines in traditionally explained by withdrawal symptoms. Previous research has not given much attention to reports that suggest that many patients oppose stopping benzodiazepines long before withdrawal symptoms have developed. This study investigates the scope of and factors associated with this pre-withdrawal treatment insistence.
Patients receiving long-term low-dosage benzodiazepines in primary care were asked to take a drug-holiday of at least 3 weeks. Sociodemographic, medication, morbidity and attitudinal variables were assessed in addition to the GPs' perceptions of their patients.
Two-thirds of the patients rejected the drug-holiday proposal. Patients who refused a drug-holiday were less educated and were using a higher percentage of long-acting benzodiazepines than patients who accepted the drug-holiday proposal. Those who refused were seen by their GPs as being more complaining, harder to satisfy and less co-operative.
These results provide evidence for drug-seeking or craving behaviour of patients who receive low-dosage benzodiazepine prescriptions. A major problem in benzodiazepine withdrawal occurs before the withdrawal programme has even begun. These data show that benzodiazepine low-dosage dependence should be considered a real form of dependence.
长期低剂量依赖苯二氮䓬类药物,传统上是用戒断症状来解释的。先前的研究没有过多关注那些表明许多患者在戒断症状出现之前很久就反对停用苯二氮䓬类药物的报告。本研究调查了这种戒断前坚持治疗的范围及相关因素。
要求在初级保健中接受长期低剂量苯二氮䓬类药物治疗的患者进行至少3周的药物假期。除了全科医生对其患者的看法外,还评估了社会人口统计学、用药、发病率和态度变量。
三分之二的患者拒绝了药物假期提议。拒绝药物假期的患者受教育程度较低,与接受药物假期提议的患者相比,使用长效苯二氮䓬类药物的比例更高。拒绝的患者被其全科医生认为抱怨更多、更难满足且不太合作。
这些结果为接受低剂量苯二氮䓬类药物处方的患者的觅药或渴望行为提供了证据。苯二氮䓬类药物戒断的一个主要问题甚至在戒断计划开始之前就已出现。这些数据表明,苯二氮䓬类药物低剂量依赖应被视为一种真正的依赖形式。
