Abstract
A method of administering a medication to a post operative patient with the medication being administered at the site of a surgery performed on the patient. The medication is formed into a time release capsule (10) having a core (12) of the medication which is dispensed within the body over a predetermined period of time. The capsule is covered with a coating (14) that dissolves within the body. The time release medication is not released until the covering is sufficiently dissolved to expose the medication. During surgery, the surgeon places placing a plurality of capsules (10–10n) in the patient's body at the surgery site. The respective capsules have different coating thicknesses so the medication contained therein is dispensed at different periods of time after the surgery as a function of the thickness of the coating.
