|Title:||Pharmaceutical composition containing fenofibrate and method for the preparation thereof|
|Abstract:||The invention concerns a pharmaceutical composition containing micronized fenofibrate, a surfactant and a binding cellulose derivative, as solubilizing adjuvant, preferably hydroxypropylmethylcellulose. The cellulose derivative represents less than 20 wt. % of the composition. The association of micronized fenofibrate with a binding cellulose derivative, as solubilizing adjuvant and a surfactant enables enhanced bioavailability of the active principle. The invention also concerns a method for preparing said composition without using any organic solvent.|

|Assignee:||Ethypharm (Sanit-Cloud, FR)|
|Filing Date:||Jun 25, 2010|
|Claims:||1. A pharmaceutical composition comprising between 50 and 300 mg of micronized fenofibrate coated on neutral microgranules in a single active layer comprising said micronized fenofibrate, as surfactant and hydroxypropyl methyl cellulose (HPMC), wherein the fenofibrate/HPMC ratio is between 5/1 and 15/1 and the surfactant represents between 1 and 10% by weight relative to the weight of fenofibrate. |
2. The composition of claim 1 in a capsule.
3. The composition of claim 1, wherein the dose of fenofibrate is 50 mg to 200 mg.
4. The composition of claim 1, wherein the neutral microgranules have a particle size between 200 and 1000 microns.
5. The composition of claim 4, wherein the neutral microgranules have a particle size between 400 and 600 microns.
6. The composition of claim 1, wherein the mean size of the fenofibrate micronized particles is less than 8 .mu.m.
7. The composition of claim 1, wherein the surfactant is sodium lauryl sulphate.
8. The composition of claim 1, wherein HPMC represents between 3 and 5% by weight relative to the weight of fenofibrate.
9. The pharmaceutical composition of claim 1, which, when administered to a patient in a fasting state at a dose of 200 mg fenofibrate, achieves a Cmax of at least 4 micrograms/ml.
10. The pharmaceutical composition of claim 1, which, when administered to a patient in a fasting state at to dose of 200 mg fenofibrate, achieves AUC of at least 119.
11. The pharmaceutical composition of claim 1, wherein at least 20% of said fenofibrate is dissolved at 5 minutes, as measured using a continuous flow cell method with a flow rate of 8 ml/min of sodium lauryl sulfate at 0.1 N.
12. The pharmaceutical composition of claim 1, wherein at least 65% of said fenofibrate is dissolved at 15 minutes, as measured using a continuous flow cell method with a flow rate of 8 ml/min of sodium lauryl sulfate at 0.1 N.
