4、单选 What is the advantage of the use of newer antidepressant?
A. They are less expensive.
B. Patients can lower the dosage.
C. They may have reduced adverse drug reactions.
D. They ae mostly used by managed care organizations.
题目解答
答案
C. They may have reduced adverse drug reactions.
解析
本题考查对新型抗抑郁药（如SSRIs、SNRIs）与传统三环类抗抑郁药核心差异的理解。解题关键在于明确新型药物的主要优势在于安全性，尤其是不良反应减少。需注意选项中常见的干扰项（如价格、剂量调整）并非其核心优势。
选项分析
选项A：They are less expensive
错误。新型抗抑郁药（如SSRIs）通常价格更高，而传统三环类药物因上市时间长、专利过期，成本较低。
选项B：Patients can lower the dosage
错误。虽然新型药物可能因安全性较高而调整剂量，但降低剂量并非其核心优势，且并非所有患者都需要调整剂量。
选项C：They may have reduced adverse drug reactions
正确。新型抗抑郁药（如SSRIs、SNRIs）显著减少了传统药物的严重不良反应，例如：
- 心脏毒性（如三环类药物的心律失常风险）降低；
- 抗胆碱能副作用（如口干、便秘）减少；
- 镇静作用减轻，患者日常活动影响较小。
选项D：They are mostly used by managed care organizations
错误。此选项仅描述新型药物的使用范围，而非其优势。新型药物的普及与其安全性相关，而非管理式医疗组织的偏好。
