A pharmaceutical dosage form adapted to supply a medicament to the oral cavity for buccal, sublingual or gingival absorption of the medicament which contains an orally administrable medicament in combination with an effervescent for use in promoting absorption of the medicament in the oral cavity. The use of an additional pH adjusting substance in combination with the effervescent for promoting the absorption drugs is also disclosed.

Sublingual buccal effervescent

The invention relates to methods and composition for improving absorption and dissolution of active ingredients of drugs. The invention provides a method of administration of an active ingredient to a mammal through a transmucosal route that includes delivering the active ingredient to a desired site in a body of the mammal, and, sequentially, at the desired site, promoting dissolution and absorption of the active ingredient. In a preferred embodiment, the pH of the localized environment of the active ingredient is sequentially modified to promote dissolution and absorption.

Sequential drug delivery systems

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.

Effervescent drug delivery system for oral administration

Novel emulsion compositions which improve the rate and/or extent of absorption of drugs are disclosed. The novel emulsion compositions of the present invention include drug-containing emulsions adsorbed onto solid particles which may be further formulated into solid dosage forms, methods of preparing such emulsion compositions and their uses thereof. The emulsion compositions and their dosage forms improve the drug-load and 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.

Emulsions as solid dosage forms for oral administration

The pharmaceutical compositions of the present invention comprise rectally and vaginally administerable dosage forms that contain effervescent agents as penetration enhancers for drugs. Effervescence occurs in the rectum or vagina, once the dosage form is administered or at a predetermined time following administration. The effervescent agents can be used alone or in combination with pH adjusting substance, which further promote dissolution and absorption of the active ingredient.

Pharmaceutical compositions for rectal and vaginal administration

A dosage form which rapidly disintegrates in the mouth and forms a viscous slurry of either microcapsules or a powder is described. The rapidly disintegrating dosage form is meant for direct oral administration by placing a tablet or capsule in the mouth of a patient. Upon disintegration, a viscosity of the resulting slurry increases so as to form an organoleptically pleasant viscous material which retards the spread of insoluble materials including the drug.

Orally disintegrable tablet forming a viscous slurry

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.
