MICRONIZED DRUG RESINATE-BASED PHARMACEUTICAL COMPOSITIONS AND METHODS OF PREPARATION THEREOF

摘要

This disclosure provides a pharmaceutical composition for oral administration, which comprises micronized ion-exchange resin particles having particle sizes less than 50 pm and at least one therapeutic agent releasably bound to the micronized resin particles through ionic interaction to form resin-therapeutic agent complexes. The resin-therapeutic agent complexes have particle sizes less than 50 pm, and the pharmaceutical composition is formulated as a dosage form providing uniform dispersion of the resin-therapeutic agent complexes with a substantially masked taste of the therapeutic agent, and a reduced gritty mouthfeel for geriatric patients and pediatric patients.
