1. A sustained release formulation of colchicine, comprising:
- (a) granules comprising 0.6 mg of colchicine or a pharmaceutically acceptable salt thereof and a binder comprising a first hydroxypropyl methylcellulose (HPMC) in an amount of 1% to 30% (w/w) of the formulation, wherein the first HPMC has a viscosity of 6 mPa·
s;
(b) a release retarding agent admixed with, or blended with, the granules in an amount of between about 20% and about 30% w/w of the formulation, which comprises equal proportions of a second HPMC and lactose monohydrate, wherein the second HPMC has a viscosity that is different from the first HPMC; and
(c) at least one pharmaceutically acceptable excipient admixed with, or blended with, the granules,wherein the sustained release formulation is in a form of a tablet or liquid, andwherein when the sustained release formulation is in the form of a tablet, the sustained release formulation further comprises a coating that is a taste-masking coating, enteric coating, seal coating, film coating, barrier coating, and/or a compression coating, wherein the coating is not a release retarding coating.

Abstract
Pharmaceutical compositions of colchicine for once-a-day oral administration are provided. The formulations comprise a sustained-release component and an optional immediate-release component, the compositions of which can be selectively adjusted, respectively, to release the active ingredient along a pre-determined or desired release profile. Methods of treating or preventing cardiovascular disease and/or inflammatory disease in mammalian subjects comprising the administration of the novel formulations disclosed herein are also provided.

27. A sustained release formulation of colchicine, comprising:
-
(a) granules comprising 0.6 mg of colchicine or a pharmaceutically acceptable salt thereof and a binder comprising a first hydroxypropyl methylcellulose (HPMC) in an amount of 1% to 30% (w/w) of the formulation; (b) a release retarding agent admixed with, or blended with, the granules in an amount of between about 20% and about 30% w/w of the formulation, which comprises equal proportions of a second HPMC having a viscosity of 4000 mPa·
s and lactose monohydrate, and wherein the second HPMC has a viscosity that is different from the first HPMC; and(c) at least one pharmaceutically acceptable excipient admixed with, or blended with, the granules, wherein the sustained release formulation is in a form of a tablet or liquid, and wherein when the sustained release formulation is in the form of a tablet, the sustained release formulation further comprises a coating that is a taste-masking coating, enteric coating, seal coating, film coating, barrier coating, and/or a compression coating, wherein the coating is not a release retarding coating.
