In life, when it comes to medication safety, many people may immediately think of the side effects of the drug itself, but in fact there are many other factors that affect medication safety, and drug dosage form is one of them. Drug dosage forms can be divided into oral, inhalation, topical, and injectable formulations according to the route of administration, and compared to adults, dosage form factors have a greater impact on children’s medication safety. Overdose, choking and coughing, misuse …… When children take medication, in addition to the side effects of the drug itself, these problems also threaten the safety of children. If the right dosage form is chosen, these problems can be avoided to some extent. When children take large granules of tablets or capsules, they are prone to getting stuck in the throat, regurgitation and vomiting. Statistics show that unsuitable oral preparations may cause gastric emptying disorders, intestinal obstruction, pyloric stenosis, and even death in children, and the vast majority of them occur in infant and young patients. When children are using slow-release or enteric tablets or capsules, if the dose per tablet (capsule) is too large, they should only be taken by breaking it open. However, for slow and controlled release formulations, breaking open not only makes the effect of slow and smooth release of the drug in the body lost, but the sudden release effect of the drug may also lead to toxic reactions. Drugs that are unstable in the gastric fluid environment (e.g., multi-enzyme tablets) or irritating to the gastrointestinal tract (e.g., indomethacin tablets) are generally made into enteric formulations, and there are corresponding safety risks associated with breaking them for use. The World Health Organization recommends the use of drops, syrups, powders, inhalers, aerosols, suppositories, etc. Parents are advised to try to choose special drugs for children because their doses, flavors, etc., are more suitable for children’s use. However, there are still very limited special drugs for children in China. Parents should try to choose a dosage form suitable for children. The medicine suitable for children should be one that does not cause swallowing difficulties and has a good taste. Granules, slow-release granules, and instant film formulations are suitable for children. These dosage forms have the following characteristics: First, they are easy to use, unlike pills and capsules that are difficult to swallow when taken, and are less likely to cause choking. Children due to the narrow airway, drugs choking into the airway is more prone to gastric spasm, blockage, resulting in violent coughing, and in severe cases can even cause asphyxiation. Second, it is easier to control the dose. These dosage forms are usually equipped with more accurate droppers, measuring cups, etc., the amount of medication is more accurate. For example, syrups or suspensions can be taken according to the specific amount required by the child at each dose, while being fast-acting, easy to take, tasty and easily accepted by children. Drops have high drug concentration and small taking volume, which is easy for children, especially infants, to take. Suppositories 50%~75% of the active ingredients are absorbed by the rectal mucosa and directly enter the blood circulation, with little gastrointestinal stimulation and little toxicity to the liver, which is also more suitable for pediatric use. Third, it is high compliance when children use these dosage forms. In addition to the better taste of these dosage forms, children have a certain sense of novelty when taking the drugs and are not easily rejected. When children take medication, it is important to feed them correctly to avoid accidents.
