ABSTRACT
@#Liquid preparations are the commonly used oral dosage forms in pediatric clinical practice.This review introduces the pediatric oral liquid dosage forms including extemporaneous preparation of oral liquid formulations, oral liquid sustained and controlled release formulations, nanosuspensions, nanoemulsions, self-nanoemulsions and milk-based liquid formulations.In addition, the efficient flavoring and taste masking technologies, using safe pharmaceutical excipients, high-demanding technical standards and verification strategies, establishing excellent workflow management systems can contribute to the development and application of pediatric oral liquid dosage forms which are safer, more effective and better compliant.This review is helpful in laying the relevant theoretical foundation for further studies on pediatric oral liquid dosage forms.
ABSTRACT
@#In China, the incidence of adverse reactions of drugs in children is twice that in adults; especially in the newborns, it is four times that in adults. The main reason is that the physiological characteristics of children are changing constantly due to that they are in a constant process of growth and development; while the pediatric medicines cannot meet the clinical needs of children in different age states. Accordingly, the development of pediatric medicines, especially oral solid preparations which are convenient for administration and storage, has attracted a lot of attention. This review introduced various pediatric oral solid dosage forms such as multiparticulates, orally disintegrating tablets(ODT)and chewable tablets. In addition, the efficient taste masking technology and accurate dose control were the further research directions for development of pediatric medicines, which would provide important theoretical references for studies on pediatric oral solid dosage forms in future.
ABSTRACT
Objective:To analyze the availability ofpediatricessential medicines in China, and to provide reference and suggestions for the further responses to the demand for pediatric medication in China. Methods :Using survey data collected from 19 provinces in China through the cooperation of the National Health Commission and our research group, the availability of pediatricessential medicines in China was analyzed from the perspectives of drug use and a-vailability with its influencing factors. Results :The survey results showed that the availability of pediatricessential medicines in China is generally low. The shortage in such medicines does not occur in individual regions, individual medical institutions or individual treatment areas, but it is still general in the surveyed parts of the country. The two fundamental reasons for the noticed shortage are :the research on special varieties for Children is expensive and the pricing mechanism of suitable varieties is inappropriate, which results in insufficient motivation for R&D Enterprises. Conclusions :This article suggests that the existing national pediatric medication support policies should be put in place as soon as possible, andbe further implemented for nationwide pediatric consumption. It is also recommended that health, drug supervision, bidding, pricing, medical insurance and other departments should work together to make more preferential policies to help enterprises develop special pediatric drugs to further promote the supply and respond to the demand of medicine for children in China.
