Development of an algorithm to identify mass production candidate molecules to develop children’s oral medicines: a North American perspective

Compounded Nonsterile Preparations and FDA-Approved Commercially Available Liquid Products for Children: A North American Update

The purpose of this work was to evaluate the suitability of recent US Food and Drug Administration (US-FDA)-approved and marketed oral liquid, powder, or granule products for children in North America, to identify the next group of Active Pharmaceutical Ingredients (APIs) that have high potential for development as commercially available FDA-approved finished liquid dosage forms, and to propose lists of compounded nonsterile preparations (CNSPs) that should be developed as commercially available FDA-approved finished liquid dosage forms, as well as those that pharmacists should continue to compound extemporaneously. Through this identification and categorization process, the pharmaceutical industry, government, and professionals are encouraged to continue to work together to improve the likelihood that patients will receive high-quality standardized extemporaneously compounded CNSPs and US-FDA-approved products.

A proposed pediatric biopharmaceutical classification system for medications for chronic diseases in children

Age-appropriate pediatric formulations for oral administration can be challenging to formulate. Development of such formulations is often time consuming, labor-intensive and costly. The Biopharmaceutical Classification System (BCS), developed more than two decades ago, is used to develop suitable oral drug formulations for adult use. In theory, some of the same principles could be applied to formulate pediatric oral liquid dosage forms. However, the present BCS system was developed using adult gastrointestinal physiologic factors. Direct extrapolation of this method to develop pediatric oral dosage forms is inappropriate due to differences in adult and pediatric gastrointestinal physiologic differences during development. To date age-appropriate BCS to guide pediatric oral liquid formulation development has not been developed for various pediatric subpopulations. The objective of this study was to provisionally classify oral liquid formulations of extemporaneously prepared drugs at our institution into an age-appropriate BCS class after elimination of any duplicate listing when matched with the most current World Health Organization's Essential Medicines List for Children available at the time of this study and other published studies that may have reported BCS classification of drugs used as extemporaneous oral liquid formulations in children to treat chronic or rare diseases. A total of 96 orally administered extemporaneously compounded liquid formulations were included in this classification. Dose numbers were calculated using age-appropriate initial gastric volume for neonates, 6-month-old infants, and children up to 6 years of age. Using age-appropriate initial gastric volumes and pediatric and neonatal Lexicomp® age-specific maximal dosing recommendations for calculation of dose numbers, the solubility classes shifted for 62.5% of the drugs studied. A significant number of currently used extemporaneously compounded oral liquid formulations for age groups of children included in this study may not provide formulations with predictable safety and efficacy. Factors used in development of adult BCS cannot be applied directly to pediatric subpopulations.

Creating a Pharmacotherapy Collaborative Practice Network to Manage Medications for Children and Youth: A Population Health Perspective

Children with special health care needs (CSHCN) use relatively high quantities of healthcare resources and have overall higher morbidity than the general pediatric population. Embedding clinical pharmacists into the Patient-Centered Medical Home (PCMH) to provide comprehensive medication management (CMM) through collaborative practice agreements (CPAs) for children, especially for CSHCN, can improve outcomes, enhance the experience of care for families, and reduce the cost of care. Potential network infrastructures for collaborative practice focused on CSHCN populations, common language and terminology for CMM, and clinical pharmacist workforce estimates are provided. Applying the results from the CMM in Primary Care grant, this paper outlines the following: (1) setting up collaborative practices for CMM between clinical pharmacists and pediatricians (primary care pediatricians and sub-specialties, such as pediatric clinical pharmacology); (2) proposing various models, organizational structures, design requirements, and shared electronic health record (EHR) needs; and (3) outlining consistent documentation of CMM by clinical pharmacists in CSHCN populations.
