Patent Images
1. An oral dosage form comprising:
- an oral controlled delivery dosing structure comprising structure that controllably delivers tramadol and a substance that comprises gabapentin; and
wherein the weight ratio of gabapentin equivalent to tramadol equivalentpresent in the oral dosage form ranges from about 0.75;
1 to about 6.5;
1; and
wherein the total weight of the tramadol and substance that comprises gabapentin present in the oral dosage form is less than about 1500 milligrams; and
wherein the oral controlled delivery dosing structure is adapted to controllably deliver the substance that comprises gabapentin at a rate that is effective to, after a single administration of the oral dosage form to a patient, maintain a gabapentin plasma drug concentration that is at least about twenty-five percent of a gabapentin Cmax throughout a window of at least about fifteen hours duration after a time at which the gabapentin Cmax occurs.
