  • Effervescent dosage form with microparticles
    Patent number: 5178878
    Abstract: A pharmaceutical dosage form incorporates microparticles which are susceptible to rupture upon chewing or which are adapted to provide substantially immediate release of the pharmaceutical ingredient contained in the microparticles. These microparticles are provided in a tablet with an effervescent disintegration agent. When the tablet is taken orally, the effervescent disintegration agent aids in rapid dissolution of the tablet and hence permits release of the microparticles, and swallowing of the microparticles, before the pharmaceutical ingredient is released from the microparticles. The system therefore provides particularly effective taste masking.
