Is it consistent with forgetting to take the medicine after meals?

[China Pharmaceutical Network Health and Health] In the hospital, doctors prescribe drugs to take medicine on time. But in people's lives, they often forget the time of medication. For example, some people often think that they should take medicine before meals after eating rice. Then, in this case, is it feasible to make up after meals?


The time of taking the medicine is based on the characteristics of the human biological rhythm and the effective plasma concentration of the drug in the body, and rationally arranging the time of administration, and has a multiplier effect on treating the disease.

To answer this question, we need to understand what is meant by medical “before meal” and “after meal”?

Before dinner

Taking medicine before meals means taking the medicine 30 to 60 minutes before meals. At this time, there is less food in the stomach, which is beneficial for the drug to be absorbed in the stomach and act on the stomach wall, and the drug can be quickly reached to the small intestine.

Such as stomach enzyme mixture and other drugs that help digestion and stomach protection.

After dinner

Taking the medicine after meals is taking the medicine 15 to 30 minutes after the meal. Since most drugs are absorbed in the small intestine, and the time when the drug mixes food reaches the small intestine, it is exactly the time when the drug begins to take effect. Therefore, drugs that are irritating to the gastric mucosa, drugs that help digestion, and drugs that need to work slowly should be taken after meals.

Such as aspirin, indomethacin, certain antibiotics and so on.

The difference between fasting and before meals

Another concept that is confusing is “fasting”. The word “mean” before meals: before eating, it is not an empty stomach before meals, only the fasting in the strict sense before breakfast.

The ideal "fasting" refers to the state before breakfast on the second day after a night of gastrointestinal rest (at least 8 hours without eating). However, in the normal clinical situation, it is also considered that the half an hour before the meal or two hours after the meal is close to the fasting state. If the special need is fasting during the day, it can be accepted between the two meals, 2 hours after the last meal. Just fine.

It is important to note that the first night or the last meal is not a big fish and a seaweed. In addition, whether you drink water, does not affect fasting or before meals. If you drink water after getting up in the morning, it is still an empty stomach; or drinking water before eating, is also a pre-dinner state. If the special dosage form, such as the oral antidiarrheal montmorillonite powder, the fasting state still needs to consider the limit of drinking water!

Clinical requirements Some drugs must be taken on an empty stomach because the absorption of these drugs is susceptible to certain ingredients in the food. On an empty stomach, the food in the digestive tract has been digested, which is beneficial to the contact between the drug and the gastrointestinal tract, so that the drug can be fully absorbed, and the drug can be quickly exerted, and the laxative, some anti-tuberculosis drugs and nourishing drugs have a quick effect.

Read the instructions carefully and you will find that there are many more terms.

Before going to bed

Take medicine for half an hour before going to bed. For example, hypnotics, laxatives, anthelmintics, anti-allergic drugs, etc., are usually taken half an hour before going to bed at night. Due to the action of hormones in the body, the blood pressure of the human body is low at night, therefore, antihypertensive drugs should not be taken at night.

3 times a day

It does not mean taking it at three meals. Instead, it divides the average of 24 hours into 3 segments, and tries to do it every 8 hours. Similarly, 2 times a day is once every 12 hours. This blood concentration is the most stable and the drug is the best. However, there are many nuances in the timing of taking different drugs, so be sure to communicate with your doctor before taking it.

Service

Take one dose a day.

when necessary

Means use as needed. Not necessarily at the time of onset, it may be used as needed to prevent seizures or prodromal symptoms. If it is an acute attack, you may miss the best treatment time.

In summary, the physiological changes of the human body are biologically periodic. Under the control of the biological clock, the functions of the human body's basal metabolism, body temperature changes, blood sugar levels, hormone secretion, etc. all have rhythm and peaks and valleys. The administration of the drug should be strictly adhered to in order to better exert the efficacy of the drug.

Modern medicine is more about individualized treatment. If you find that you are missing medication, it is best to consult a doctor and do not make your own claims. Different drugs vary widely and cannot be generalized.
