[ China Pharmaceutical Network Health Health ] "Drug before or after meals" is a problem that people often ask when they are sick. Scientific medication has become a matter of doctors often pleading with patients. However, the requirements for taking medicine for scientific use are not limited to this. In order to obtain a therapeutic effect after taking the drug, and without causing side effects, it is necessary to pay attention to the time and frequency of taking the drug.
Compliance with medication time and medication frequency
1. The number of medications and the interval between doses must be in accordance with the doctor's instructions, do not arbitrarily adjust.
The number of times of administration and the interval of administration time depend on the half-life of the drug in the body. Most drugs are 3 times a day, the elimination of fast drugs in the body, the number can be slightly increased; in the body to eliminate slow drugs, can be taken twice a day (such as sulfadiazine, sulfamethoxazole) or even once. Liver and kidney function are impaired, and the half-life of the drug is prolonged. Be alert to possible accumulation of poisoning. Some drugs have restrictions on their daily dose and course of treatment due to their toxicity or slow elimination.
2. The time of medication depends on the specific situation
As for the time of taking the drug (such as before and after meals), it depends on the specific drug. Some drugs, such as anthelmintic drugs, are required to be taken on a half-empty or fasting basis. If the drug is separated by food after serving, it is difficult to achieve therapeutic purposes. Contrast agents such as iopanoic acid are only 12 to 14 hours after serving. In the gallbladder, so take the medicine the night before, the next morning can be filmed.
Most of the antacids and gastrointestinal antispasmodic drugs (such as propylamine bromide) are better before meals, but the stomach sedatives and bromomethylamine oxime are usually taken after meals. These two classes of drugs can also be taken at the onset of symptoms. Anti-asthmatic drugs and analgesics can also be taken at the onset of symptoms.
In general, in addition to bitter stomach drugs, astringent drugs, antacids, gastrointestinal antispasmodics, intestinal anti-infectives, choleretic drugs (more than pre-dinner), anthelmintic drugs, salt laxatives (fasting Other than half-empty stomach), hypnotics, laxatives (before bedtime), the rest can be taken after meals, especially drugs that are irritating to the stomach (such as indomethacin, acetylsalicylic acid, iron, etc.) ), it must be served after meals. After meals, the food will affect the absorption of the drug, generally slower absorption, and the effect will be slower.
