编辑同志:我父亲今年62岁,因治疗前列腺肥大而住院。有一天,他起床时突然晕厥,跌倒在地,短暂意识丧失,全身出汗,血压低,平卧10分钟后血压上升,所幸没发生意外。医生说,造成我父亲跌倒的原因可能是服用药物的副作用。请问,哪些药物易致老人跌倒? Editor’s Comrade: My dad, 62, is hospitalized for treating benign prostatic hyperplasia. One day he suddenly fainted when he got up, fell to the ground, lost his short-term consciousness, sweaty his body and had low blood pressure. After supine for 10 minutes, his blood pressure increased. Fortunately, no accident occurred. The doctor said the reason that caused my father to fall may be the side effect of taking the drug. Excuse me, what medicines can cause the elderly to fall?
