Tolerability and Acceptance of Two Oral Hydrocortisone Compounding Formulation for Pediatrics

Adrenal insufficiency arises from inadequate synthesis of adrenal hormones, with primary, secondary, or tertiary forms depending on the defect's location-adrenal, pituitary, or hypothalamic. Hydrocortisone (17-Hydroxycorticosterone) is the preferred cortisol replacement. Pediatric hydrocortisone formulations are not commercially available in any presentation. Consequently, compounded formulations are prepared as standard practice. Vall d'Hebron University Hospital's Pharmacy Service currently provides a liquid hydrocortisone formulation for these patients. While liquid formulations are often preferred due to their better dose adjustment and improved acceptability by pediatric patients, they have limitations such as shorter shelf life, possible special storage conditions, and taste problems due to bitter active ingredients. In some cases, particularly for chronic treatments with established and constant doses, other options such as capsules may be considered. Capsules offer longer stability, longer expiration dates, and do not require special storage conditions. In this context, this study aims to determine the tolerability and acceptance of a new solid magistral formula in the form of chewable hydrocortisone tablets, prepared using a volume dosing device (M3DIMAKERTM 3D printer), compared to the usually preferred liquid formulation. Each of the formulations will be administered for three months. Evaluating the results will allow us to improve assistance to pediatric patients by offering the formulation with better tolerability and acceptance. The study will take place at Vall d'Hebron University Hospital, led by the Pharmacy Service in collaboration with the Pediatric Endocrinology Service.
