Small knowledge of commonly used drugs

1. What is the common sense of safe medication in daily life?

Drugs should be prepared at home: ① Common drugs: common drugs for respiratory diseases such as colds, asthma and tracheitis; Commonly used drugs for digestive tract diseases such as diarrhea, vomiting and loss of appetite; Others, such as cod liver oil, calcium tablets, topical drugs for the treatment of otorhinolaryngology and skin diseases.

② Commonly used drugs: There are many kinds of drugs to treat various systemic diseases, so you only need to prepare commonly used drugs at home. There are many drugs with similar effects, so you can choose some for later use.

③ Safe drugs: Children have strict requirements for drug use, and improper use can easily lead to adverse consequences. Spare drugs should be drugs with few side effects, little toxic reaction and simple use.

4 Easy to use: Oral drugs and topical drugs are the main standing drugs at home. Try to use injections as little as possible, because improper use and poor mastery can easily lead to adverse consequences such as allergies and poisoning.

⑤ Drugs that are easy to store: Family-owned drugs are generally stored for a long time. This requires less drugs to be stored, especially those that are easy to deteriorate and fail.

Specifically, tablets should be given priority to, supplemented by water. Choose some drugs with good packaging for storage.

⑥ Drugs easy to master: All kinds of drugs have their own dosage, usage, indications and side effects, which are difficult for complicated parents to master. Therefore, the drugs that should be stored should be few and refined, with few kinds, easy to remember and use, and less mistakes.

Taking cold medicine should not eat sweets: medical experiments have proved that if you take cold medicine containing acetaminophen on an empty stomach, it usually takes about 20 minutes, and the drug concentration in the blood can reach the highest. When the patient has sugary food in his stomach, the absorption of cold medicine will be delayed for 2 hours, thus affecting his function.

Eating too many sweets will also make a lot of sugar enter the blood, which will lead to poor appetite of patients. In addition, the sugar in sweets can promote the secretion of cortisol after entering the human body. Cortisol has an inhibitory effect on the immune system, which will greatly reduce the patient's physical resistance, so remember not to eat sweets and sweet drinks when you have a cold.

It is not recommended to drink juice or milk when taking antibiotics: China people must take antibiotics for almost any serious disease. Whether taking antibiotics correctly or not, please remember not to drink juice or milk for 2 hours before and after taking antibiotics.

This is because fruit juice, especially the fruit acid rich in fresh fruit juice, will accelerate the dissolution of antibiotics, reduce the efficacy of antibiotics, and may also generate harmful intermediate products and increase toxic and side effects; However, milk will reduce the activity of antibiotics, so that the efficacy can not be fully exerted and the due curative effect can not be achieved. It is not advisable to drink milk when taking antidiarrheal drugs: during diarrhea, our appetite tends to decrease. In order to supplement the lost nutrition, we often drink milk with higher nutritional value instead of food, but what you don't know is that milk will not only reduce the efficacy of antidiarrheal drugs, but also easily aggravate diarrhea symptoms.

Therefore, never drink milk during diarrhea. Coffee and cola should not be drunk when taking ibuprofen: ibuprofen is what we often call fenbid, which has anti-inflammatory, analgesic and antipyretic effects.

Headache, joint pain, toothache, cold and fever can all play a certain therapeutic role. However, because ibuprofen itself has a great effect on gastric mucosa, in order to avoid the aggravation of pain, we should try to avoid drinking beverages that secrete gastric acid, such as coffee and cola, so as not to aggravate the toxic side effects of ibuprofen on gastric mucosa and even induce gastric bleeding and gastric perforation.

Taking antihypertensive drugs should not eat grapefruit: doctors suggest that it is best not to eat grapefruit or drink grapefruit juice during taking antihypertensive drugs. If you must eat grapefruit, you should take corresponding antihypertensive drugs 12 hours after eating grapefruit.

This is because grapefruit contains a chemical called furocoumarin, which can affect the function of an enzyme in the liver, greatly reduce the metabolic effect of this enzyme on drugs, and lead to the increase of blood drug concentration in the body. At the same time, naringin in grapefruit will accelerate the absorption of drugs in the intestine.

Too fast drug absorption and slow metabolism will lead to too high drug concentration in blood. When antihypertensive drugs are taken with grapefruit, patients will have some drug overdose reactions, including blood pressure drop, slow heart rate and even severe shock.

You should not eat bananas and oranges when taking diuretics: diuretics are commonly used in clinic, but we need to pay attention to the fact that potassium will remain in the blood during taking diuretics. However, bananas, oranges and other fruits are high in potassium. After taking them, patients accumulate too much potassium, which is easy to induce heart and blood pressure complications.

3. What are the basic drugs commonly used by ordinary people?

With the gradual improvement of people's living standards and the continuous popularization of medical and health knowledge, people's awareness of disease prevention and fitness has been continuously strengthened, and many families have medicines, so that some minor problems can be treated in time.

However, any drug has two sides, which can not only cure diseases, but also endanger human health. Therefore, we should prepare a small amount of safe and effective commonly used drugs according to the health status of family members, and learn to use them scientifically and reasonably.

Families can generally reserve the following medicines. (1) antipyretic and analgesic drugs: such as aspirin, painkillers and indomethacin.

(2) Drugs for treating colds: such as Puganmin, Contek, Ganmaotong, Li Qiang Yinqiao Tablet and Baijiahei Ganmao Tablet; (3) Drugs for relieving cough and eliminating phlegm: such as Bisuping, Kebiqing, Shedan Chuanbei Liquid, etc.

(1l) External painkillers: such as rheumatism ointment and safflower oil. (12) Others: Band-Aids, essential balm, cooling oil, sterilized cotton swabs, gauze, adhesive tape, etc.

4. What are the essential drugs in life?

Clinical thermometer, band-aid, sterile gauze bandage, round-headed scissors, pliers, disposable gloves, antibiotic ointment, aspirin, painkillers, indomethacin, cardiovascular and cerebrovascular drugs, sphygmomanometer, blood glucose meter, cold-reducing, cough-relieving and asthma-relieving drugs, etc.

List of essential drugs for family first aid kit: 1, first aid manual According to the statistics of the International Red Cross, only 12% of adults in the world can take emergency rescue measures, and only 5% of them are effective. Many families have a lot of things in their first-aid medicine boxes, but they don't know the first-aid methods.

Lack of first aid knowledge makes many of us lose our hands and feet in the accident, so a first aid manual is the most important. Generally speaking, first aid manuals can be bought in bookstores, or downloaded and bound online.

2. When using the mercury thermometer, remove the mercury column first, and wipe the sweat clip under the armpit 10 minutes. When using the electronic thermometer, the probe should be placed at the position where the temperature needs to be measured until the buzzer is heard and the measured value is read. The service life of household electronic thermometer is also about 5 years.

3. Band-aid is used for dressing small wounds and wounds, and there are three sizes: large, medium and small. Waterproof band-aid and medicine band-aid should be prepared.

Sterile gauze is used to cover the wound. It can neither leave cotton silk on the wound like cotton, nor affect the wound when it is removed.

Bandages can also be used. Bandages are elastic and can be used to wrap wounds without affecting blood circulation. 2 inches for hands and 3 inches for feet.

The triangular bandage, also called triangular bandage, has many uses, and can support the injured upper limb, fix the dressing or fracture. 6. Round-headed scissors, pliers, disposable gloves and round-headed scissors are relatively safe and can be used to cut adhesive tapes or bandages.

It can also be used to cut clothes when necessary. Tweezers can be used to hold dressings instead of hands, or to remove dirt from wounds.

Disposable gloves can avoid direct contact with wounds and cross infection. 7. The mask is mainly used to isolate the pollution of mouth and nasal cavity gas to the wound. Need to be reminded that you must wash your hands before and after wearing it, and replace it immediately after wearing it once.

8. When a flashlight is used for rescue in a dark environment, it can be used for lighting, and it can also be used for pupil reaction of the fainting person. 9. Wash the wound with 0.9% normal saline.

Based on hygiene requirements, it is best to choose independent small packages or medium bottles. It should be noted that the leftovers after opening should be thrown away and not put into the first aid kit.

If not, you can use unopened distilled water or mineral water instead. 10, disinfection paper towels are used to clean the skin, sterilize, tear open the package and directly rub the skin.

1 1. Plastic wrap wraps the burned and scalded parts before sending them to the hospital, because it won't stick to the wound. 12. The ice pack is placed at the position of bruise, muscle strain or joint sprain, which makes the microvessels contract and helps to reduce swelling.

When nosebleeds, you can put it on the forehead of the injured person to help stop the bleeding. 13, antibiotic ointment, such as chlortetracycline ointment and erythromycin ointment, is used to protect the exposed inner skin in the case of knee and elbow abrasions.

Note: Do not use antibiotics at will. Please read the instructions carefully. Or follow the doctor's advice.

14, local antihistamines and aspirin (or other over-the-counter analgesics) antihistamines are mainly used for antiallergic, such as chlorpheniramine, cisplatin (astemizole), diphenhydramine, etc. Analgesics, such as aspirin, painkillers and indomethacin. For relieving mild to moderate pain, such as headache, joint pain, toothache, myalgia, neuralgia and dysmenorrhea, it should be prepared for at least three to five days.

If you still don't get better after taking the medicine for 5 hours, please go to the hospital as soon as possible to avoid delaying your illness. It should be reminded that the medicines in the family first aid kit should be cleaned every 3~6 months.

If your family has various chronic diseases, heart diseases, etc. You should supplement the first aid kit according to your personal situation. What drugs should the elderly keep at home? 1, nine times out of ten, cardiovascular and cerebrovascular drugs, the elderly are now suffering from cardiovascular diseases. In addition to the drugs that need to be taken according to the doctor's advice, you may wish to prepare more nitroglycerin at ordinary times. Please take it immediately if you feel chest tightness, heart discomfort or angina pectoris.

Now that nitroglycerin has a new spray, it is more convenient to spray it twice. If parents suffer from cerebrovascular diseases, their children can prepare some angong Niuhuang pills at home. If they find signs of stroke, such as sudden slurred speech and inability to speak, it's best to let them take one.

2. Poor gastrointestinal function of digestive drugs is also a common problem for the elderly. On the one hand, they are prone to flatulence after eating, so they can prepare some gastrointestinal motility drugs like motilium; On the other hand, constipation is not a big problem, but many elderly people die suddenly.

Therefore, some laxatives should be prepared, such as kaiselu. 3, sphygmomanometer, blood glucose meter For antihypertensive drugs, it is best for the elderly with poor ears to choose an electronic blood glucose meter, and the accuracy is generally no problem.

When you feel dizzy, chest tightness and other uncomfortable symptoms, you'd better measure them in time. In addition, it is best to measure blood pressure after getting up in the morning so as to find abnormalities earlier.

Blood glucose meter is an essential thing for diabetic patients, and it can be measured anytime and anywhere when you are uncomfortable. 4, oxygen bag patients with heart disease or poor lung function, it is recommended to prepare one.

However, it should be noted that the oxygen bag can only solve the "temporary pain". Once the symptoms are relieved, you must go to a regular hospital. 5. Thermometer The sensitivity of the elderly to temperature changes is not as good as before, and most of the time they don't feel that they have a fever.

Therefore, when the elderly are depressed and have no appetite, it is best to measure their body temperature first to see if they have a fever. Moreover, fever is the "Depth Charge" of many major diseases, so we can't be careless.

In addition, drugs for colds, fever, cough and asthma can also be used for many years. Experts remind that the family medicine box is used for emergency. If the sudden symptoms are relieved after taking the medicine, you should go to the hospital for systematic examination so as not to miss the treatment opportunity.

Many elderly people suddenly fall ill, so it is necessary to pay attention to the placement and use of small family medicine boxes: 1. Children should put the medicine box at the bedside of the elderly. If they are sick at night, they can reach it with one hand. 2. Check the expired drugs every 3 months.

3, try to choose over-the-counter drugs, because they are generally effective and simple to use, and the commonly used drugs are best to be few and refined, and the amount does not need too much. The most important thing is to see if it can "get rid of the disease".

5. Medical tips

The conflict between aspirin and alcohol. Wine is first oxidized to acetaldehyde in the body, and then oxidized to acetic acid. Aspirin will prevent acetaldehyde from being oxidized to acetic acid, which will lead to acetaldehyde accumulation in the body, aggravate fever and general pain, and easily cause liver damage. Berberine conflicts with tea. Tea contains about 10% tannic acid, which is easily decomposed into tannic acid in the body, and tannic acid will precipitate alkaloids in berberine and reduce its efficacy. Therefore, you can't drink tea for 2 hours before and after taking berberine.

Ibuprofen conflicts with coffee and cola. Ibuprofen (Fenbid) has a * * effect on gastric mucosa, while caffeine in caffeine and cocaine in cola will secrete gastric acid, which will aggravate the side effects of ibuprofen on gastric mucosa and even induce gastric bleeding and gastric perforation. Antibiotics conflict with milk and juice. Don't drink milk or juice within 2 hours before and after taking antibiotics, because milk will reduce the activity of antibiotics and make the drug effect unable to give full play; Fruit acid rich in fruit juice (especially fresh fruit juice) will accelerate the dissolution of antibiotics, which will not only reduce the efficacy, but also increase the side effects.

Calcium tablets conflict with spinach. Spinach contains a lot of potassium oxalate. Electrolytic oxalate ions will precipitate calcium ions after entering the body, which will hinder the absorption of calcium by the body and easily generate calcium oxalate stones. Do not eat spinach within 2 hours before and after taking calcium tablets, or cook spinach before eating.

Anti-allergic drugs conflict with cheese and meat products. Avoid eating foods rich in histidine, such as cheese and meat products, while taking anti-allergic drugs. Because histidine will be converted into histamine in the body, and antiallergic drugs inhibit the decomposition of histamine, leading to histamine accumulation, inducing dizziness, headache, palpitations and other uncomfortable symptoms.

Antidiarrheal drugs conflict with milk. You can't drink milk when taking antidiarrheal drugs, because milk not only reduces the efficacy of antidiarrheal drugs, but also contains lactose, which is easy to aggravate diarrhea.

Diuretics conflict with bananas and oranges. Potassium will remain in the blood during taking diuretics. If you eat bananas and oranges rich in potassium, excessive accumulation of potassium in your body can easily lead to heart and blood pressure complications.

Vitamin c conflicts with shrimp. Don't eat shrimp within 2 hours before and after taking vitamin C, because the copper in shrimp will oxidize vitamin C and make it ineffective. The pentavalent arsenic in shrimp easily reacts with vitamin C to produce toxic trivalent arsenic.

Antihypertensive drugs conflict with grapefruit juice. You can't drink grapefruit juice when taking antihypertensive drugs, because naringin in grapefruit juice will affect the function of an enzyme in the liver, which is related to the metabolism of antihypertensive drugs, and it is easy to cause high drug concentration in the blood and increase side effects.

6. Basic knowledge of pharmacy

Let me tell you what I think. This topic is quite big. Indeed, there are too many things about pharmacy in life, but what I want to say is what changes pharmacy has brought to our lives and what enlightenment it has given me. What I feel most is the importance of safe, effective, reasonable and economical medication to every patient or every life! Drugs are used to cure diseases and save lives, but in fact, a considerable number of patients die not because of the disease itself, but because of medical accidents or unreasonable medication. I have seen more than one or two cases, so pharmacy lets me know the importance of life and cherish it! This is the original intention of human beings to invent drugs, in order to make everyone in the world healthy.

Personally, I think that if you want to do something good, this article should not just wander around the Internet, but look for pharmacy in your life, such as going to the pharmacy for internship, going to the hospital for further study and going to the pharmaceutical factory for exercise. Only in this way can we really realize what life pharmacy lets you know. After all, contact at school is limited.

Everyone's experience is different. I only say my personal experience, which may not be suitable for your article writing. Grading is not a problem. You can give it or not. I just hope what I said can help you. Remember one thing in life, find it in life and experience it! This is a good topic, so you'd better collect more information and write it when everything is ripe.

7. Common drug management knowledge

First, what is the knowledge of drug classification management? Drug classification management is an internationally accepted management method.

According to the principle of drug safety and effectiveness, drugs are classified into prescription drugs and over-the-counter drugs according to their varieties, specifications, indications, doses and routes of administration, and corresponding management regulations are formulated. Since the founding of New China, China has first implemented classified management of * * * *, toxic drugs for medical use, radioactive drugs and drug rehabilitation drugs. At present, the core of classified management of prescription drugs and over-the-counter drugs is to strengthen the management of prescription drugs, standardize the management of over-the-counter drugs, reduce the occurrence of irrational drug use, and effectively ensure the safety and effectiveness of people's drug use.

Second, what are prescription drugs and over-the-counter drugs? Prescription drugs refer to drugs that can only be prepared, purchased and used according to the prescriptions of practicing doctors or assistant practicing doctors. Over-the-counter drugs refer to drugs that can be judged, purchased and used by themselves without the prescription of medical practitioners or assistant medical practitioners.

Prescription drugs are called prescription drugs or ethical drugs in English and OTC drugs in English. In the United States, it is also called "Over The Cornter", which has become a common name all over the world. Third, how to identify non-prescription drugs? (1) Article 7 of the Administrative Measures for the Classification of Prescription Drugs and Non-prescription Drugs (Trial) stipulates that the words of non-prescription drugs designated by the state must be printed on the packaging of non-prescription drugs.

(2) Article 7 of the Interim Provisions on the Administration of the Circulation of Prescription Drugs and Non-prescription Drugs (for Trial Implementation) points out that for non-prescription drugs entering the field of drug circulation, the production enterprise shall conspicuously print corresponding instructions on the drug packaging or drug instructions. The specific content is: please read the drug instructions carefully and use them according to the instructions or buy and use them under the guidance of pharmacists! Fourth, what is safe and rational drug use? Safe and rational drug use refers to the rational choice of drugs according to the condition, the patient's physique and the overall situation of drugs, so as to truly "suit the right medicine" and accurately use drugs at the right dose and time.

Pay attention to the contraindications, adverse reactions and interactions of this drug. And pay attention to spend as little money as possible.

In this way, drugs can be used safely, reasonably, effectively and economically. 5. How to read the drug instructions accurately? Drug instructions are one of the legal bases to guide how to use drugs.

Accurate reading and understanding of instructions before medication is the premise of safe medication. First of all, we should know the name of the drug.

Regular drug instructions all contain the generic name, trade name, English name and chemical name of the drug (among which over-the-counter drugs have no chemical name). Generally speaking, users can avoid repeated drug use as long as they know the proper name of the drug, that is, the generic name.

Because a drug has only one generic name (that is, the legal name stipulated by the state), unlike several trade names. In the column of indications, patients who use over-the-counter drugs can judge whether their diseases meet the indications and prescribe the correct drugs by themselves, and they can choose to buy them with the help of pharmacists.

Secondly, we need to know the usage of drugs, such as taking them before meals, after meals and before going to bed, once or three times a day, and we must carefully observe whether they are taken orally, externally or by injection. Third, pay attention to the dosage of drugs, and you must use drugs according to the instructions.

The dose in the general instructions is for adults, which must be accurately converted before taking by the elderly and children. It is particularly important to pay attention to contraindications, adverse reactions, drug interactions and precautions. When reading the instructions. If there is any ambiguity, you should consult a pharmacist or doctor.

6. Why should OTC drugs be divided into Class A and Class B? What is its symbol? One of the reasons for implementing drug classification management is to facilitate the general public. Some minor injuries and ailments can be purchased nearby, avoiding the pain of asking for leave and wasting money and labor. In order to make the public more convenient, some over-the-counter drugs with higher safety are classified as Class B, which can be sold in supermarkets, hotels and department stores. OTC logo of Class A is red, and Class B is green. Seven, how to identify the validity of drugs? Validity refers to the approved use period of drugs, which means that the quality of drugs can be guaranteed under certain storage conditions. The method of expressing the expiry date of drugs, arranged in chronological order, can generally be used until a certain year and a certain month. For example, if the expiry date is June 2003, it means that drugs will start to expire on July 1 day, 2003.

The Drug Administration Law also stipulates that the production batch number, production date and expiration date should be indicated on the packaging box or instructions of drugs. Imported drugs must also be written in Chinese in accordance with the above expressions for public reading.

Eight, over-the-counter drugs will not have serious adverse reactions? Over-the-counter drugs are drugs. Generally speaking, adverse reactions are less and lighter, but they are not absolute. Some over-the-counter drugs can also cause serious adverse reactions in a few people, and sometimes even lead to death. Therefore, over-the-counter drugs should be taken in accordance with the instructions for drug use, and the number of times of taking should not be increased casually, nor should the methods or ways of taking drugs be changed.

9. What is drug allergic reaction? Drugs are foreign "foreign bodies" to people, and people's bodies are born with the ability to deal with "foreign bodies", which is originally a self-protection ability of the body. However, if this reaction exceeds a certain limit, it will cause harm to the body.

Allergic reaction is a cross-border reaction of human body to drugs, which is essentially an immune reaction. Drug allergic reaction belongs to adverse drug reactions.

X. how to choose drugs safely and reasonably? First of all, you should diagnose your illness, and then prescribe the right medicine. You can't take medicine just because of your self-feeling or a certain symptom. For example, fever and headache are symptoms of many diseases.

Can't simply take some painkillers to reduce fever; Another example is abdominal pain, which is also a symptom of some diseases. If you use painkillers indiscriminately, it will cover up some symptoms of acute abdomen, delay the illness and cause serious consequences. The second is to understand the nature, characteristics, indications and adverse reactions of drugs, and choose drugs with good curative effect and low toxicity. This is why doctors often say "first choice drugs" and "second-line drugs".

For example, there are many kinds of painkillers. For the common cold, headache, joint pain, neuropathic pain and female menstrual abdominal pain, you can choose any one of acetaminophen, fenbid, painkillers and aspirin. Belladonna and atropine can be used for abdominal pain caused by gastrointestinal spasm.
