摘要

Several diseases that affect the pediatric population, e.g., heart diseases, cannot be efficiently treated because of the absence of a suitable dosage form. In this sense, orally disintegrating tablets (ODT) are solid dosage forms that are gaining acceptance. Losartan potassium (LP) is the drug of choice for managing pediatric arterial hypertension, although its bitter taste represents a major challenge to treatment compliance. To mitigate this drawback, this study aimed to develop palatable ODT, by the incorporation of spray-dried powders (SDP), composed of LP, Eudragit® polymers and adjuvants (i.e., colloidal silicon dioxide, mannitol, and PEG4000). The SDP were analyzed in terms of production yield and encapsulation efficiency. Selected SDP were incorporated into ODT by direct compression, and characterized in terms of mechanical and pharmaceutical properties, as well as palatability. Tablets with satisfactory disintegration time, hardness, and friability were obtained, though different performance during in vitro dissolution study. In the palatability study, the volunteer panel confirmed that the ODT-7SDP formulation, prepared by spray drying with Eudragit® E PO and colloidal silicon dioxide, showed a marked reduction in LP bitterness. In conclusion, the applied technologies successfully reduced the bitter taste of LP, enabling its oral administration in the form of ODT, particularly for pediatric patients.
