General empty pharmaceutical capsules are made of gelatin and HPMC as raw materials. Rarely does it have any effect on a person's health, but there are a few things we need to be aware of when taking medication.

    Most of the drugs in capsules are irritating to the gastric mucosa and esophagus or are easily decomposed and destroyed by digestive juices. The capsules cannot be shelled. After shelling, the efficacy of the drug will be reduced, the digestive tract will be damaged, or the particles of the drug may even be choked into the trachea, causing danger.

    The drug in the sustained-release capsule is a sustained-release drug. Only by swallowing it completely can the drug delay the process of release, absorption, distribution, metabolism, and excretion in the body, so as to prolong the effect of the drug and exert the best efficacy. If you remove the capsule and take it, the drug will not work at all, and it is easy to cause adverse drug reactions. Therefore, the sustained-release capsule must not be opened and swallowed.

    Capsules are best not taken with hot water. Taking hot water will make the capsule dissolve quickly, and the outer skin of the capsule can easily stick to the throat or esophagus, thereby weakening or losing the intended effect of the capsule. It should be served with cold or warm water.

    For some light capsules, because each capsule is very light and its specific gravity is smaller than that of water, you should lower your head and swallow it when taking it, so that it can smoothly pass through the throat and enter the esophagus. If you swallow the capsule with your head up, the water will be swallowed quickly, and the capsule may also stick to the upper part of the throat, which will not only be unable to swallow but also easily cause choking.
