There are many medicines for tablets. In addition to the most common ordinary tablets, there are many tablets, such as lozenges, sublingual tablets, oral patches, chewable tablets, dispersible tablets, effervescent tablets, and the like.
Ordinary tablets have suitable hardness and are convenient for oral administration. The preparation process is complicated, the purity is high, the impurities are small, the bioavailability is high, and the dosage is accurate. Tablets are not well preserved and are suitable for long-term storage, even in high temperature and humid environments in the south.
The capsule is filled with the drug powder or granule directly in the gelatin capsules, and is not affected by pressure and the like. When the capsule is opened, the pharmaceutical ingredient can be rapidly dispersed, dissolved and absorbed in the gastrointestinal tract. However, the capsule shell is easy to soften and mildew in a high temperature and humid environment, and requires high storage conditions. Some drugs must be dissolved in the intestines, so they need to be filled in enteric capsules to ensure that the drug is effective in the intestinal tract.
The capsule can also cover up the bad smell of the drug and the appearance is neat and beautiful. After the capsule enters the human body, the capsule is melted and the drug is fully dissolved. It takes at least 15 to 30 minutes.
The gastrointestinal tract is stimulated to be small, and it is not easy to cause damage to the gastric mucosa. It should be taken before meals. Take the capsules and take them whole. Do not open the capsule shell and only take the powder. Because of the loss of the capsule-protected drug, the taste may be extremely poor, and it may also damage the mouth, corrode the esophagus, and the like.
In fact, in addition to the obvious difference in absorption time of different dosage forms of drugs, under normal circumstances, the amount of drug absorbed by the human body within a certain period of time will not be much different. The different dosage forms of the product generally do not affect the efficacy of the drug, mainly for the convenience of taking and absorbing.
