Assignee:	POZEN INC. (Chapel Hill, NC)
Application Number:	15/338,825
Patent Claims:	1. A method for delivering a pharmaceutical composition to a patient in need thereof, comprising orally administering to said patient a pharmaceutical composition in unit dose form comprising acetylsalicylic acid, or pharmaceutically acceptable salt thereof, in an amount to provide 325 mg of acetylsalicylic acid, and omeprazole, or pharmaceutically acceptable salt thereof, in an amount to provided 40 mg of omeprazole, wherein said omeprazole, or pharmaceutically acceptable salt thereof, is released from said unit dose form at a pH of from about 0 or greater, and the unit dose form targets: i) a pharmacokinetic (pk) profile for acetylsalicylic acid where: a) the dose has a acetylsalicylic acid mean C.sub.max of about 2.0 to about 3.0 .mu.g/mL and a median time to maximum concentration (T.sub.max) of from about 3.0 to about 3.5 hours, and/or b) the dose has a salicylic acid mean C.sub.max of about 15 to about 16.5 .mu.g/mL and a median time to maximum concentration (T.sub.max) of from about 3.0 to about 3.5 hours, ii) a pharmacokinetic (pk) profile for omeprazole where the dose has a mean area under the plasma concentration-time curve from time zero when the dose is administered to about 12 hours after the dose is administered (AUC.sub.0-12) of about 0.8 to about 2.5 hr/*.mu.g/mL wherein the pharmaceutical composition further targets a mean % time at which intragastric pH remains at about 4.0 or greater for about a 24 hour period after reaching steady state of at least about 50%. 2. The method according to claim 1, wherein the pk profile for acetylsalicylic acid has a mean acetylsalicylic acid C.sub.max of at least 2.36 .mu.g/ml and a mean salicylic acid C.sub.max of at least 15.3 .mu.g/ml. 3. The method according to claim 1, wherein the pk profile for acetylsalicylic acid has a mean acetylsalicylic acid C.sub.max of about 2.91 .mu.g/ml and a mean salicylic acid C.sub.max of at least 16.2 .mu.g/ml. 4. The method according to claim 3, wherein the % coefficient of variation for acetylsalicylic acid is about 54%, and the coefficient of variation for salicylic acid is about 29%. 5. The method according to claim 1, wherein the omeprazole mean area under the plasma concentration-time curve from time zero when the dose is administered to about 12 hours after the dose is administered (AUC.sub.0-12) is about 2.174 hr/*.mu.g/mL. 6. The method according to claim 5, wherein the % coefficient of variation for the omeprazole mean area under the plasma concentration-time curve from time zero when the dose is administered to about 12 hours after the dose is administered (AUC.sub.0-12) is about 88%. 7. The method according to claim 1, wherein the omeprazole mean area under the plasma concentration-time curve from time zero when the dose is administered to about 24 hours after the dose is administered (AUC.sub.0-24) of about 2.187 hr/*.mu.g/mL. 8. The method according to claim 7, wherein the % coefficient of variation for the omeprazole mean area under the plasma concentration-time curve from time zero when the dose is administered to about 24 hours after the dose is administered (AUC.sub.0-24) is about 88%. 9. The method according to claim 1, wherein said unit dose form is administered for a period of at least about 7 days. 10. The method according to claim 1, wherein said unit dose form is administered for a period of at least about 14 days. 11. The method according to claim 1, wherein said unit dose form is a multilayer tablet comprising at least one core and at least a first layer and a second layer, wherein: i) said core comprises acetylsalicylic acid, or pharmaceutically acceptable salt thereof; ii) said first layer is a coating that at least begins to dissolve when the pH of the surrounding medium is about 3.5 or greater; and iii) said second layer comprises omeprazole, wherein said omeprazole is released at a pH of from about 0 or greater. 12. The method according to claim 11, wherein said omeprazole is released at a pH of from about 0 to about 2. 13. The method according to claim 1, wherein said patient in need thereof is being treated for a disease or disorder selected from pain and inflammation. 14. The method according to claim 1, wherein said patient in need thereof is being treated for cardiovascular disease, osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, or a combination thereof.
