摘要： The pharmaceutical compositions of the present invention comprise orally administerable dosage forms that use effervescence as a penetration enhancer for drugs known, or suspected, of having poor bioavailability. Effervescence can occur in the stomach, once the tablet or other dosage form is ingested. In addition to effervescence in the stomach, or as alternative technique, by the use of appropriate coatings and other techniques, the effervescence can occur in other parts of the gastrointestinal tract, including, but not limited to, the esophagus, duodenum, and colon. The site of effervescence and drug release is chosen to correspond with the segment of the gastrointestinal tract displaying maximal absorption of the formulated drug, or to gain some other therapeutic advantage.

摘要： Novel pharmaceutical compositions which improve the rate and/or extent of absorption of drugs are disclosed. The novel pharmaceutical compositions of the present invention comprise drug-containing microemulsions adsorbed onto solid particles which may be further formulated into solid dosage forms. The compositions and dosage forms of the present invention improve the bioavailability of a wide range of drugs including drugs that are known or suspected of having poor bioavailability by the utilization of several different mechanisms.
