Some experts say that in fact, empty gelatin capsule are available in a variety of shapes, including spherical, elliptical, rectangular and cylindrical shapes. It is not known why we originally designed this shape as it is.
From the point of view of swallowing, the main consideration may be the size of the capsule. The size of the capsule shell is divided into eight types of 000, 00, 0, 1, 2, 3, 4, and 5 from large to small. The commonly used numbers are 0 to 5. The larger the number, the smaller the volume. This is mainly related to the density, crystal state and particle size of the filled drug, and the capsule shell of a suitable size is selected according to the volume occupied by the drug dose.
Some patients have suggested that the capsule is difficult to swallow. On the one hand, it may be related to the size of the capsule. On the other hand, it may be related to some patients taking medicine and not drinking water. Dry swallow capsules, it is easy to make the capsule stick to the wall of the esophagus. The capsule shell has dissolved before reaching the designated place, which is easy to cause local irritation.
Therefore, drink a mouthful of water before taking the capsule, and take another bite when taking the medicine to avoid the capsule sticking to the mouth and throat. The contents of some capsule medicines are corrosive, and the released chemicals may burn the esophageal mucosa. After swallowing, drink some water. There are 3 narrowities in the adult esophagus, especially in the second place, which will block the passage of the capsule.
In addition, it is best to take the warm water when serving the capsule, do not use hot water or juice to serve. The former will accelerate the melting of the capsule, which may cause the capsule to stick to the throat or esophagus. The latter is acidic, which will dissolve many drugs in advance, which is not conducive to absorption, and may also affect the exertion of some drugs.
