Calcium carbonate tablets can be swallowed as a whole, the analysis is as follows: Firstly, the volume of calcium carbonate tablets used in clinical practice is very small, so patients do not need to chew the calcium tablets in the process of taking them, they can swallow the whole calcium tablets directly, and they will not get stuck in the throat, and they will not cause damage to the gastrointestinal tract and esophagus, so they can be taken with confidence. Secondly, calcium carbonate tablets are easily digested and absorbed, so it only takes a few hours to be completely digested and absorbed by the body after entering the gastrointestinal tract, thus entering the blood circulation, there is no need to chew it up, and the whole swallow can be completely absorbed by the body. Third, calcium carbonate tablets swallowed as a whole is also conducive to prevent the rapid dilution by stomach acid or kidney excretion, so that the retention time of calcium tablets in the body is longer, increasing the absorption time of the gastrointestinal tract, which can improve the absorption rate and utilization of drugs.
