Title:Coated tablets
Abstract: Disclosed is a pharmaceutically acceptable oral dosage form comprising fenofibrate, phospholipid, a buffer salt, a water-soluble bulking agent selected from maltodextrin, mannitol, and combinations thereof, a cellulosic additive, beads or crystals of a pharmaceutically acceptable water-soluble excipient support material, a polyvinylpyrrolidone or crospovidone, croscarmellose sodium, granular mannitol, sodium dodecyl sulfate, silicon dioxide, and a stearate, wherein the fenofibrate is in the form of microparticles, and wherein at least a portion of the phospholipid is coated on the surfaces of the fenofibrate microparticles, the phospholipid coated microparticles are embedded in a matrix comprising the water-soluble bulking agent, phospholipid that is not coated on the microparticles, the buffer salt and the cellulosic additive, and the matrix is coated on up to 100% of the surfaces of the beads or crystals of the excipient support material.

Assignee: Jagotec AG (Muttenz, CH)
Filing Date:May 02, 2003
Application Number:10/428,007
Claims:1. A pharmaceutically acceptable oral dosage form of fenofibrate comprising fenofibrate present in an amount of from about 15% w/w to about 20% w/w of the dosage form; phospholipid present in an amount of from about 1% w/w to about 8% w/w of the dosage form; a buffer salt present in an amount of from about 0.1% w/w to about 0.5% w/w of the dosage forth; one or more water-soluble bulking agent selected from maltodextrin and mannitol present in an amount of from about 7% w/w to about 20% w/w of the dosage form; a cellulosic additive present in an amount of from about 3% w/w to about 8% w/w of the dosage form; beads or crystals of a pharmaceutically acceptable water-soluble excipient support material present in an amount of from about 12% w/w to 16% w/w of the dosage form; a polyvinylpyrrolidone or crospovidone present in an amount of from about 5% w/w to about 30% w/w of the dosage form; croscarmellose sodium present in an amount of from about 1% w/w to about 6% w/w of the dosage form; granular mannitol present in an amount of from about 3% w/w to about 30% w/w of the dosage form; sodium dodecyl sulfate present in an amount of from about 1% w/w to about 4% of the dosage form; silicon dioxide present in an amount of up to about 1% w/w of the dosage form; and a stearate present in an amount of up to about 1% w/w of the dosage form; wherein the fenofibrate is in the form of microparticles coated with phospholipid, wherein the phospholipid coated microparticles are embedded in a matrix comprising the water-soluble bulking agent, phospholipid that is not coated on the microparticles, the buffer salt and the cellulosic additive, and wherein the surface of the beads or crystals of the pharmaceutically acceptable water-soluble excipient is coated with the matrix.

2. The dosage form of claim 1, wherein the fenofibrate is present in an amount of from about 18% w/w to about 19.5% w/w of the tablet.

3. The dosage form of claim 1, wherein the phospholipid is present in an amount of from about 2% w/w to about 6% w/w of the tablet.

4. The dosage form of claim 1, wherein the buffer salt is present in an amount of from 0.1% w/w to about 0.2% w/w of the tablet.

5. The dosage form of claim 1, wherein the bulking agent is maltodextrin present in an amount of from about 9% w/w to about 20% w/w of the tablet.

6. The dosage form of claim 1, wherein the bulking agent is mannitol present in an amount of from about 7% w/w to about 20% w/w of the tablet.
