Abstract

A solid or semi-solid pharmaceutical dosage form comprising non-steroidal-anti-inflammatory drugs, in particular propionic acid derivatives such as ibuprofen, along with a second active ingredient having a shorter therapeutically effective plasma concentration duration, such as phenylephrine, and methods of administering the same are provided. This method provides improved therapeutic effect, in particular pain relief along with decongestant relief, over extended time periods.

First claim

We claim:

1. A solid or semi-solid pharmaceutical dosage form comprising:
a) a first portion comprising ibuprofen and/or a pharmaceutically acceptable salt thereof, wherein the first active ingredient is released from the dosage form in a immediate release manner upon contact of the dosage form with a dissolution medium; and
b) a second portion comprising:
i. particle cores comprised of a second active ingredient, wherein said second active ingredient is phenylephrine or a pharmaceutically acceptable salt thereof;
ii. a semi-permeable coating layer covering said particle cores to form coated particles, wherein said semi-permeable coating layer comprises ethylcellulose; and
iii. a protective coating layer covering said coated particles, wherein the second active ingredient is released from the second portion in a modified release manner upon contact of the dosage form with the dissolution medium, and
wherein the duration of the therapeutic effect of the second active ingredient and the duration of the therapeutic effect of the first active ingredient is about 4 hours to about 6 hours.

2. The dosage form of claim 1 further comprising a matrix.

3. The dosage form of claim 1 , wherein said semi-permeable coating layer further comprises one or more agents selected from the group consisting of cellulose acetate, non-enteric polymethacrylates, and mixtures thereof.

4. The dosage form of claim 1 , wherein said protective coating layer comprises enteric polymers selected from the group consisting of hydroxypropyl methylcellulose phthalate, hydroxypropyl methylcellulose acetate succinate, cellulose acetate phthalate, polyvinylacetate phthalate, shellac, enteric polymethacrylate-based polymers, and copolymers and mixtures thereof.

5. The dosage form of claim 1 , wherein the protective coating layer-comprises a lipid, a wax, or mixtures thereof.

6. The dosage form of claim 1 , wherein the protective coating layer-comprises an enteric coating, and wherein the particle cores of the second portion comprise a third pH independent protective coating layer that covers the protective coating layer.

7. The dosage form of claim 1 , wherein said protective coating layer comprises a material selected from the group consisting of sucrose fatty acid esters; monoglycerides; diglycerides; triglycerides; glyceryl behenate; glyceryl palmitostearate; glyceryl tristearate; glyceryl trilaurylate; glyceryl myristate; lauroyl macrogol-32 glycerides; stearoyl macrogol-32 glyceride; fatty acid esters having a fatty acid chain length of about C10 to about C40; and mixtures thereof.

8. The dosage form of claim 1 , wherein said protective coating layer comprises a wax selected from the group consisting of carnauba wax, spermaceti wax, beeswax, candelilla wax, shellac wax, beeswax, microcrystalline wax, and paraffin wax, and mixtures thereof.

9. The dosage form of claim 1 , wherein the semi-permeable coating layer further comprises, based upon the total dry weight of the semi-permeable coating layer, from about 0.1% to about 40% of a plasticizer.

10. The dosage form of claim 1 , wherein the protective coating further comprises, based upon the total dry weight of the protective coating, from about 0.1% to about 40% of a plasticizer.

11. The dosage form of claim 1 , wherein the weight ratio of the semipermeable coating layer to the protective coating layer is about 10:90 to about 90:10.

12. The dosage form of claim 1 , wherein the second portion comprises of, based upon the total dry weight of the second portion,
a) from about 5 percent to about 80 percent of the semi-permeable coating layer;
b) from about 10 percent to about 90 percent of the protective coating layer; and
c) from about 20 percent to about 80 percent of the particle cores.

13. The dosage form of claim 1 , wherein the dosage form comprises, based upon the total weight of the dosage form, from about 1.0% to about 80% of the first portion; and from about 0.01% to about 15% of the second portion.

14. The dosage form of claim 1 , wherein the dosage form comprises, based upon the total weight of the dosage form,
a) from about 1.0% to about 80% of the first active ingredient; and
b) from about 0.01% to about 10% of the second active ingredient.

15. The dosage form of claim 1 , wherein the dosage form is coated with an outer coating comprised of a release modifying coating or an immediate release coating.

16. The dosage form of claim 15 , further comprising a subcoating intermediate to the outer coating.

17. The dosage form of claim 1 , wherein the protective layer comprises a material selected from the group consisting of enteric polymers, lipids, waxes, elastic coatings, and copolymers and mixtures thereof.
