Whether it belongs to Chinese patent medicine or western medicine, all western medicines are basically eaten about 30 minutes after meals, which does not hurt the stomach. Traditional Chinese medicine and Chinese patent medicine can be eaten on an empty stomach in the morning and after meals in the evening. In view of your schedule and the western medicine you probably eat, you can get up at 7 o'clock and buy breakfast halfway.

Eat first or take medicine first

1, drugs that must be taken before meals.

Some drugs need to be taken before meals, usually 10- 30 minutes before meals. At this time, there is no food in the stomach, and the absorption and utilization rate of drugs is the highest, which can maintain the blood concentration of the body and quickly play the role of drugs.

Generally, these drugs have little stimulation to the gastrointestinal tract, and the drugs often taken before meals include drugs to protect the spleen and stomach, drugs to stop diarrhea, drugs to protect the stomach wall, and nourishing drugs. In addition, most Chinese medicines need to be taken before breakfast.

2. Drugs that must be taken when eating.

There are very few drugs that need to be taken when eating. Generally, these drugs are digestive AIDS, which can help the digestion of the stomach when taken at meals. Such as multienzyme tablet, pepsin mixture, etc.

3. Drugs that need to be taken after meals

Most drugs need to be taken after meals, especially western medicine. It is usually taken 30 minutes after meals. At this time, there are some foods in the stomach, which can reduce the stimulation of the gastrointestinal tract after the food enters the stomach.

In addition, take it half an hour after meals, at this time, some food has entered the intestine, and the medicine will not be mixed with food after entering, which will affect absorption.

4. Drugs that need to be taken on an empty stomach

Some drugs should not be taken before or after meals, which can not only avoid the influence of food on drugs, but also make drugs enter the intestine quickly and maintain a high concentration, which has good curative effect.

For example, some anthelmintics need to be taken on an empty stomach, and parasites are mostly in the intestines. Taking medicine on an empty stomach can quickly reach the lesion site, with rapid absorption and high blood concentration.

5. Drugs that need to be taken on time

The taking of some drugs has little to do with before and after meals, because it takes a certain time to maintain a certain blood concentration. For example, some sustained-release tablets release drugs at a uniform speed, and if they are not taken again after a certain period of time, the blood concentration in the body will decrease and the food efficacy will decrease. However, some antibiotics can last 4-6 hours. After this time, the blood concentration in the body will drop and it will not play a role in treating diseases. Therefore, different drugs have different medication methods, and many times they should be taken according to the doctor's advice and cannot be used blindly.

How long is the best time to take medicine before and after meals?

Drugs that should be taken before meals include hypoglycemic drugs such as glipizide, gliclazide and acarbose. Stomach-strengthening drugs such as Xiaoer San, Longdan Huang Tablet, Jianwei Bao and so on. Gastric mucosal protective agents such as sucralfate, bismuth pectin, bismuth potassium citrate, gastrointestinal motility drugs such as domperidone, metoclopramide, cisapride, antidiarrheal drugs such as medicinal activated carbon, smecta, and tonic drugs such as ginseng and velvet antler. And captopril, roxithromycin, azithromycin, alendronate, cod liver oil, norfloxacin, lomefloxacin, cefalexin, sodium bicarbonate, astemizole, levamisole, tetracycline, cefaclor, ampicillin, rifampicin, etc.

Drugs to be taken after meals include oral anti-inflammatory drugs, antibiotics, analgesics, aqua, medicated wine, multi-enzyme tablets, lactase and other digestive AIDS, antacids such as metoclopramide, cimetidine and famotidine, anti-inflammatory painkillers such as acetaminophen, aspirin and indomethacin, vitamins such as vitamin B2, vitamin C, vitamin B complex, cefuroxime, doxycycline and imod.

The difference between taking medicine before and after meals

There are two main reasons for taking drugs before meals: First, in order to give full play to the local effects of some drugs on the gastrointestinal tract, such as bitter drugs and stomach-invigorating drugs, the administration time has a significant impact on the effects of these drugs, which should generally be taken about 10 minutes before meals to increase gastric juice secretion and appetite. Some drugs, such as laxatives, such as magnesium sulfate and castor oil, accelerate defecation through local action, and the effect occurs quickly. In order to ensure the efficacy, it is customary to take it on an empty stomach in the morning. Another example is disgusting expectorants (salt drugs such as ammonium chloride and potassium iodide, and Chinese medicines such as Radix Platycodi and Radix Polygalae) and small doses of emetic drugs such as tartar emetic and root emetic. Oral administration can stimulate gastric mucosa, cause mild nausea and reflexively promote respiratory secretion, so taking medicine on an empty stomach is effective. Another example is insect repellent. Taking it on an empty stomach is beneficial to the contact between drugs and worms and give full play to their efficacy. Second, taking it on an empty stomach can avoid bloating and the interference of food on the absorption of certain drugs. For example, taking rifampicin on an empty stomach can be absorbed quickly and completely, but after taking it, the absorption of rifampicin is greatly reduced. Another example is tetracycline (tetracycline, oxytetracycline, doxycycline, etc. ) can form conjugates with multivalent cations such as calcium, magnesium, aluminum, iron, bismuth, etc. So drugs or foods containing these cations will reduce their absorption.

It is emphasized that there are two situations after meals: first, drugs that are irritating to gastric mucosa, such as iron, furan drugs, salicylate, p-aminosalicylic acid, chloroquine, etc., can reduce their irritation to gastric mucosa; Second, taking medicine after meals can slow down the gastric emptying speed, so that drugs can reach the intestinal absorption site slowly and evenly, which is beneficial to the absorption of some drugs. For example, when taking vitamin B2 on an empty stomach, the stomach empties quickly, and a large amount of vitamin B2 appears in the absorption part of the small intestine, which may be due to limited absorption and only part of vitamin B2 is absorbed. On the contrary, after taking vitamin B2 after meals, the drug slowly and evenly reaches the absorption site of the small intestine, where the amount of B2 is lower than the saturation level, so the absorption is relatively complete. Others, such as cod liver oil, can cause nausea and vomiting and should also be taken after meals.
