对某些药物所致停药不良反应的认识已越来越清楚.近20年来该现象被认为与药物数量增加密切相关,且其中某些药物被广泛用于临床.这些药物有着作用于神经、内分泌、血液及心血管系统的复杂的“反馈”机制.这表明突然停药可诱发正常内稳态的短暂失衡并可致各种不良反应. Recognition of the side effects caused by discontinuation of some drugs has become more and more clear.It has been considered that this phenomenon is closely related to the increase of the number of drugs in the past 20 years and some of these drugs are widely used in clinical practice.These drugs have roles in nerve, Endocrine, blood and cardiovascular systems, suggesting that sudden withdrawal may induce a brief imbalance of normal homeostasis and may cause various adverse effects.
