药物中毒,在医院里时常可以見到,發生最多的原因不外是剂量太大,药物本身具有很强的毒性,或患者对药物有过敏反应等。由于过量而中毒的,可能因某些药物的有效量和中毒量很接近,如洋地黄等;又有些药物要达到疗效时,往往产生輕度的中毒症狀,如否琉氏溶液(1％亞砷酸鉀溶液)等。有些药物如大量或長期应用,也可能产生中毒症狀,如水楊酸鈉。有的药物毒性较强,应用时極易产生中毒症狀,如酒石酸銻鉀、吐根素等。此外对药物有过敏反应时,即使剂量非常小,亦可引起严重的反应甚至死亡。
Drug poisoning, often seen in the hospital, the most common cause is nothing but the dose is too large, the drug itself has a strong toxicity, or the patient has an allergic reaction to the drug. Due to excessive poisoning may be due to the effective amount of certain drugs and the amount of poisoning is very close, such as digitalis and so on; and some drugs to achieve curative effect, often have mild symptoms of poisoning, such as whether or Liu’s solution (1% Arsenate solution) and the like. Some drugs, such as large or long-term use, may also cause symptoms of poisoning, such as sodium salicylate. Some drugs are more toxic, when applied easily produce symptoms of poisoning, such as antimony potassium tartrate, ibuprofen and so on. In addition, allergic reactions to drugs, even if the dose is very small, can cause serious reactions and even death.
