Many approved oral paediatric medicines continue to have poor taste acceptance, suggesting that the ingredient blends employed in these medicines are not adequately effective in taste-masking drugs with strongly aversive tastes. To address this inadequacy, this narrative review provides a comparative evaluation of taste-masking ingredients used by the pharmaceutical industry with those employed in the food industry, as well as food items used by caregivers to mask the unpalatable taste of medicines for young children. Information was sourced from academic databases, industry publications, and caregiver forums on informal social platforms. Ingredients were classified into sweeteners, salts, acids, fats, peptides/amino acids, flavourants, cyclodextrins and polymers, with their taste-masking mechanisms delineated into receptor-level interactions and the creation of physical barriers and alternative dominant taste. Their applications are compared across the regulated medicinal and consumer food products, and in home remedies. Sweeteners show the highest cross-domain convergence as they are used in medicinal and food products and are recommended by caregivers. Peptides, amino acids, salt and texture modifiers applied in food and home remedies may have translational potential in medicines. Challenges, including drug–food interactions, regulatory constraints, and the need for combination approaches, are addressed. A decision framework is also designed to guide the development of simple, acceptable, and effective ingredient-based taste-masking systems for drugs with aversive tastes.
