With the development of technology, car has been the necessary transportation for people to travel. Due to traffic congestion, car accidents are also increasing year by year. Recently, Germany, Britain, the United States and Japan and many other developed countries in the transportation of scientists on a large number of traffic accidents to investigate the study, the results coincidentally found that: due to the driver to take drugs inadvertently lead to inattention, dizziness, dizziness, ringing in the ears, poor vision,,, tiredness, mental fatigue, unresponsiveness, dystonia, etc. caused by traffic accidents, far more than the traffic accidents caused by drinking and driving to be more than 2.8 The number of traffic accidents caused by drugs is 2.8 times higher than that caused by drinking and driving. However, the drug “road killer” has not been able to attract attention. Easily make the driver traffic accidents of drugs are mainly the following categories: 1, sedative, hypnotic drugs University of California, Dr. Greenway on a large number of traffic accidents investigations found that about 13% of the driver traffic accidents and take sedative, hypnotic drugs, painkillers containing sedatives related.

In short, all sedative drugs, can produce different degrees of inhibition of the cerebral cortex, drivers taking such drugs, often dizziness, fatigue, slow brain response, energy dispersion, and some even lethargy, most likely to cause traffic accidents. 2, anti-psychotic drugs such as chlorpromazine can cause sleepiness, dizziness, fatigue, blurred vision and postural hypotension and other adverse reactions; promethazine can cause dizziness, weakness, blurred vision and inattention and other adverse reactions. Therefore, taking such drugs during driving can increase the incidence of traffic accidents. 3, anti-allergic drugs such as Benzphenhydramine, Feinagan (ipecac), Mink Jing, ketotifen, chlorpheniramine (paracetamol) and other antihistamines are more commonly used in the clinic of the anti-allergic drugs, these drugs on the central nervous system has a strong inhibitory effect, people take these drugs, often dizziness, drowsiness, blurred vision, dry mouth, tiredness, and other adverse reactions. Therefore, drivers should not take these drugs during driving. 4, anti-cold medicines This kind of drugs in the cold through, cold clear, grams of sensible, anaesthesia, fast-acting cold capsule, most of which contain antihistamines, with sedative effect, after taking, will induce the patient’s drowsiness, dizziness, drowsiness and other adverse reactions. Therefore, can not engage in highly concentrated driving work. 5, some of the treatment of gastric disease medicine treatment of gastric disease commonly used drugs metoclopramide (gastroenterology), although with low toxicity and other characteristics, but some people take the drug, prone to neurological adverse reactions, mainly manifested as acute dystonia, and paroxysmal episodes. If this phenomenon occurs while driving, the driver can not grasp the steering wheel, honk the horn, step on the brake, etc., and is prone to serious consequences. Therefore, drivers should be careful with these drugs. 6, antispasmodic drugs such as atropine, scopolamine, tincture of mandrake, after the horse Tropicana, etc., often with dry mouth, dizziness, pupil dilation, blurred vision, heart rate acceleration and other adverse reactions. Sometimes accompanied by hallucinations and delirium, delusional speech, and even convulsions. Therefore, drivers should not take these drugs during driving. 7, antipyretic and analgesic drugs used in the treatment of migraine phenothiazine, used for inflammatory pain indomethacin (anti-inflammatory pain), Schwarzenegger and analgesic drugs such as morphine, codeine, etc., the efficacy of the treatment is more ideal, but the side effects are also more.

Therefore, drivers should not take these drugs during driving. 9, anti-peptic ulcer drugs such as Losec (omeprazole) can cause dizziness, headache, tinnitus, blurred vision, drowsiness, numbness of the lower limbs, sensory anomalies and other adverse reactions; such as Tai Gastro-mei (tetramisidine), Ranitidine, Famotidine and so on can also cause dizziness, headache, fatigue and drowsiness and other adverse reactions. Drivers taking such drugs during driving will also increase the risk of car accidents. 10, antiarrhythmic drugs such as cardioplegia, cardioplegia, cardioplegia, cardioplegia, etc., there will be dizziness, drowsiness, fatigue, bradycardia, blood pressure drop and other phenomena, and even fainting. Therefore, drivers should not take such drugs during driving. 11, blood pressure lowering drugs such as Lovoxil, Boyd’s, Nimodipine and Nitrendipine can cause dizziness, headache and drowsiness and other adverse reactions. In addition, some people in taking guanethidine, eugenol and other blood pressure lowering drugs, often muscle weakness, bradycardia, postural hypotension and blurred vision and other reactions. This is due to the impact of drugs, so that the sympathetic nerve reflex regulation of vascular tone function failure, resulting in blood flow to the lower extremities due to gravity, resulting in temporary ischemia of the brain. Therefore, drivers should be careful to take such drugs. 12, gynecological drugs such as progesterone, clomiphene and oral contraceptives can cause dizziness, fatigue, drowsiness and drowsiness and other adverse reactions. Therefore, after taking the drug can not engage in highly concentrated driving work. Experts remind drivers that when using drugs for medical reasons, they must read the instructions in detail to understand the effects of the drugs, their uses, possible adverse reactions and precautions. Avoid the use of drugs that affect the central nervous system, the ophthalmic nerve, the auditory nerve and other parts of the human body during the work period. If necessary, adjust the time of medication, arrange for the drugs with more side effects to be taken at rest or before going to sleep at night. Others, such as riding a motorcycle, bicycling, driving a lathe, working at height, etc., should also use the above drugs with caution.
