Abstract

A solid pharmaceutical composition containing pregabalin is described. The composition includes a matrix forming agent and a swelling agent and is suitable for once daily oral administration. Exemplary matrix forming agents include mixtures of polyvinyl acetate and polyvinylpyrrolidone, and exemplary swelling agents include cross-linked polymers of polyvinylpyrrolidone.

Claims

1-15. -15. (canceled)

16. :

A pharmaceutical composition comprising an active pharmaceutical ingredient and excipients, the active pharmaceutical ingredient comprising pregabalin, or a pharmaceutically acceptable complex, salt, solvate or hydrate thereof, and the excipients comprising a matrix forming agent and a swelling agent, the matrix forming agent comprising polyvinyl acetate and polyvinylpyrrolidone, and the swelling agent comprising crosslinked polyvinylpyrrolidone, wherein the pharmaceutical composition is adapted for once-daily oral dosing;

wherein the pregabalin comprises from about 5% to about 60% of the pharmaceutical composition by weight;

the matrix forming agent comprises from about 5% to about 45% of the pharmaceutical composition by weight, and the swelling agent comprises from about 15% to about 70% of the pharmaceutical composition by weight.

17. The pharmaceutical composition according to claim 16 in which:

a) said matrix forming agent comprises about 20% to about 35% of the pharmaceutical composition by weight, and;

b) said swelling agent comprises about 20% to about 55% of the pharmaceutical composition by weight.

18. The formulation according to claim 16 in which the polyvinyl acetate is present in the quantity of about 60% to about 90% by weight based on the total weight of the polyvinyl acetate and polyvinylpyrrolidone.

19. The formulation according to claim 16 in which the polyvinyl acetate is present in the quantity of about 70% to about 90% by weight based on the total weight of the polyvinyl acetate and polyvinylpyrrolidone.

20. A pharmaceutical formulation suitable for once-a-day administration comprising:

a) pregabalin, or a pharmaceutically acceptable complex, salt, solvate or hydrate thereof, present in the quantity of from about 5% to about 60%, based on the total weight of the formulation;

b) a matrix of polyvinyl acetate and polyvinylpyrrolidone, in which the polyvinyl acetate is present in the quantity of about 70% to about 90% based on the total weight of the polyvinyl acetate and polyvinylpyrrolidine and the matrix is present in the quantity of about 20% to 35% by weight, based on the total weight of the formulation, and;

c) cross linked polyvinylpyrrolidone, present in the quantity of about 10% to about 35% by weight, based on the total weight of the formulation.

21. The formulation according to claim 20 in which the cross linked polyvinylpyrrolidone is present in the quantity of from about 20% to about 30% by weight, based on the total weight of the formulation.
