The lack of appropriate medicines for children has a significant impact on health care practices in various countries around the world, including Thailand. The unavailability of pediatric medicines in hospital formularies causes issues regarding off-label use and extemporaneous preparation, resulting in safety and quality risks relating to the use of medicines among children. This research aimed to identify missing pediatric formulations based on the experience of healthcare professionals in a teaching hospital in northern Thailand. A cross-sectional survey was conducted to collect data on missing pediatric formulations, the reasons for their inaccessibility, their off-label uses, their reactions to the situation, and suggestions to improve access to these identified medications. The survey was distributed to all physicians, nurses, and pharmacists involved in prescribing, preparing, dispensing, and administering pediatric medicines. A total of 218 subjects responded to the survey. Omeprazole, sildenafil, and spironolactone suspension were most often identified as missing formulations for children by physicians and pharmacists. They are unavailable on the Thai market or in any hospital formulary. For nurses, sodium bicarbonate, potassium chloride, and chloral hydrate were the most problematic formulations in terms of preparation, acceptability, and administration. These medicines were difficult to swallow because of their taste or texture.

Lack of access to child-appropriate medicines results in off-label use. This study aimed to explore medicine management for paediatric patients and to highlight the challenges of the healthcare system under the universal health coverage of Thailand. Semi-structured interviews were conducted with 35 healthcare practitioners working in the public hospital network of Chiang Mai province from February to September 2020. Participants were asked about their experiences in managing the medicine supply for children. Findings revealed that paediatric patients had limited access to age-appropriate medicines. Children’s medicines are rarely selected for inclusion into hospital formularies because of constraining regulations and limited budgets. Additionally, child-appropriate formulations are unavailable on the market. Pharmaceutical compounding is unavoidable. Prepared products are provided weekly or monthly because of product stability concerns. Often, tablets are dispensed, and caregivers are instructed to cut up a tablet and disperse it in syrup in order to obtain a smaller dose in a dosage form appropriate for children to use at home. Without systematic support, access to safe and quality medicines for children is limited.
