Oral preparation of obeticholic acid
The present invention pertains to an oral preparation having exceptional elutability, the oral preparation containing obeticholic acid or a pharmacologically acceptable salt thereof, a water-soluble excipient, a disintegrating agent, and a water-soluble polymer binder, wherein the oral preparation is a quick-release tablet.
1. An oral preparation, comprising obeticholic acid or a pharmacologically acceptable salt thereof, (i) a water-soluble excipient, wherein the water-soluble excipient is a sugar or a sugar alcohol; (ii) a disintegrating agent, wherein the disintegrating agent is selected from any one or more of a starch, sodium croscarmellose, carmellose, low-substituted hydroxypropyl cellulose, and crospovidone; and (iii) a water-soluble polymer binder, wherein the water-soluble polymer binder is a polyvinyl alcohol-based resin, wherein the preparation is a quick-release tablet.
2. The oral preparation of claim 1 , wherein the sugar or sugar alcohol is mannitol or lactose.
3. The oral preparation of claim 1 , wherein the starch is a pre-gelatinized starch.
4. The oral preparation of claim 3 , wherein the pre-gelatinized starch is a partly pre-gelatinized starch.
5. The oral preparation of claim 1 , wherein the disintegrating agent comprises two different types, (iia) a disintegrating agent A and (iib) a disintegrating agent B.
6. The oral preparation of claim 5 , wherein the disintegrating agent A is selected from a starch, sodium croscarmellose, carmellose, calcium carmellose, sodium carmellose, crospovidone, low-substituted hydroxypropyl cellulose, and sodium carboxymethyl starch, and the disintegrating agent B is any disintegrating agent other than the disintegrating agent A, selected from a starch, sodium croscarmellose, carmellose, calcium carmellose, sodium carmellose, crospovidone, low-substituted hydroxypropyl cellulose, and sodium carboxymethyl starch.
7. The oral preparation of claim 6 , wherein the disintegrating agent A is a starch.
8. The oral preparation of claim 7 , wherein the starch is a pre-gelatinized starch or partly pre-gelatinized starch.
9. The oral preparation of claim 6 , wherein the disintegrating agent A is low-substituted hydroxypropyl cellulose.
10. The oral preparation of claim 6 , wherein the disintegrating agent B is any of crospovidone, sodium croscarmellose, or sodium carboxymethyl starch.
11. The oral preparation of claim 10 , wherein the disintegrating agent B is crospovidone.
12. The oral preparation of claim 1 , wherein the polyvinyl alcohol-based resin is a polyvinyl alcohol, polyvinyl alcohol derivative, or polyvinyl alcohol copolymer.
13. The oral preparation of claim 1 , wherein the obeticholic acid or pharmacologically acceptable salt thereof is an amorphous form.
14. The oral preparation of claim 1 , wherein the obeticholic acid or pharmacologically acceptable salt thereof is obeticholic acid.
