Problems solved by technology

[0002] The technical shortcomings of different dosage forms of antiepileptic drugs include: for injections, children have a sense of fear, and it is difficult to consciously cooperate with doctors and parents to use them on time; for capsules, when children use less than one pill, they often take the medicine in the capsule The method of pouring out water and taking it; for tablets, when the dosage for children is less than one tablet, it needs to be divided artificially, resulting in inaccurate dosage. Some coated tablets and sustained-release tablets lose their specific functions such as protection and shielding Taste, controlled release, isolation and other effects, there are no reports of oral emulsions of antiepileptic drugs
