Methods for manufacturing such a pharmaceutical composition are also provided. Methods for treating pain using such compositions are also demonstrated.
1 . A method of creating a condition in a host that is responsive to an agonist, the method comprising administering a multi-layer pharmaceutical composition comprising an agonist and an antagonist thereof that are not in direct contact with one another in the intact form of the composition, wherein administration of the intact form of the composition to the host effectively treats the condition in a manner more efficacious than placebo when measure using the Brief Pain Inventory.
2 . The method of claim 1 wherein the host is treated for tip to twelve, weeks.
3 . A method of treating a condition in a host that is responsive to an agonist, the method comprising administering a multi-layer pharmaceutical composition comprising an agonist and an antagonist thereof that, are not in direct contact with one another in the intact form of the composition, wherein administration of the intact form of the composition to the host, effectively treats the condition in a manner more efficacious than placebo when measured using the WOMAC Osteoarthritis Index.
