Sedation drugs that contain atropine most likely also contain scopolamine. Atropine is the most important drug in the treatment of nerve agent poisoning due to its ability to combat the effect of the nerve agent in the airways. Atropine relieves narrowing of the airways caused by nerve agent poisoning, reducing the risk of fatal suffocation. There are many symptoms and signs associated with atropine intoxication. Some of the signs and symptoms are hallucinations, dry mouth, dry and red skin, dilated and non-reactive pupils, depression, circulatory collapse, drop in blood pressure, muscle incoordination, blurred vision and restlessness. Another symptom is faulty respiratory system, which is the most devastating symptom. When a person experiences respiratory failure, it can lead to coma or paralysis. Death may occur after paralysis or coma. In case of overdose, atropine can cause very serious consequences, but deaths due to atropine poisoning are very rare but can occur in adults and children. Atropine is the safest alkaloid among all potential alkaloids. Since death caused by atropine alone is very rare, the fatal dose has not been discovered medically. In case of overdose, the side effects of dry mouth, blurred vision, photophobia, anhidrosis and constipation are notable.
