1. Why drug capsules
Capsules are just a cloak or vest for drugs, and the purpose of using them is not just to make them look good, of course, but mainly to make them easy to take and achieve the best results.
When a person is sick, the drugs must pass through the gastrointestinal tract digestion and absorption into the blood, but also through the liver breakdown. But a significant number of powders, particles, liquids and tablets are either bitter and irritating, volatile or easily broken down by saliva in the mouth, and some can be inhaled into the airways, causing side effects. So capsules protect the mouth and digestive tract, are easy to swallow, and allow the drug to work best. And to let the drug play the best role, also want to avoid drugs destroyed by gastric acid, because some drugs need to be dissolved and absorbed in the intestine, so, need to use special membrane materials (such as gelatin, cellulose, polysaccharide, etc.) made of capsules, powder, liquid and other drugs in accordance with the dose into the bag. In addition, drugs have a half-life, which refers to the time it takes for a drug to reduce its maximum concentration in the blood by half. The half-life of a drug reflects the rate of elimination (excretion, biotransformation, storage, etc.) of the drug in the body and shows the relationship between the time the drug is in the body and its blood concentration. Therefore, it is the main basis for deciding the dosage and frequency of administration. A drug with a long half-life is eliminated slowly in the body, resulting in a long interval of administration. A drug with a short half-life is eliminated quickly in the body, resulting in a short administration time. For drugs with a short half-life, they need to be taken frequently to maintain the concentration of the drug in the blood, and to avoid the trouble of taking them frequently, they need to be wrapped in special capsules called slow-release capsules. In addition, the drug concentration of sustained-release capsules can avoid the high and low effective blood drug concentration after frequent administration of general preparations. Meanwhile, the toxic and side effects of sustained-release capsules are smaller than that of general preparations. As a result, many drugs, such as ibuprofen, aspirin, tylenol, etc., are available in sustained-release capsules.
2. Plant capsules are hope
Professionals suggest that plant gelatin can be used instead of traditional gelatin to reduce the opportunity for some unscrupulous enterprises to use industrial gelatin. In addition, the use of plant capsules can also meet the world has some religious ethnic and vegetarians should not take animal materials (animal capsules) drugs, at the same time can avoid some pathogens cross infection, such as the spread of mad cow disease.
Plant capsules are rich in raw materials, such as carrageenan starch, malt essence, all kinds of cellulose, alginate, wax, and some plasticizers, such as glycerin, sorbitol, maltitol, propylene glycol, polyethylene glycol and water. From the development of gelatin, the traditional capsule (animal capsule) was developed from the 1930s, until today, the main form of drug packaging. And the plant capsule research has only 20 years time, as long as given time, in technology, equipment and raw materials and other aspects of the breakthrough, plant capsule will have a great success. Because, it not only has a wide range of uses, there are better security.
