1. A twice-a-day solid oral controlled-release dosage form of a pharmaceutically acceptable salt of hydrocodone, the dosage form comprising:
- a therapeutically effective amount of a pharmaceutically acceptable salt of hydrocodone, andtwo different types of multiparticulates in the form of granules, spheroids, or pellets,a first type of said multiparticulates comprising a first portion of the pharmaceutically acceptable salt of hydrocodone and providing an immediate release of hydrocodone,a second type of said multiparticulates comprising a remaining portion of the pharmaceutically acceptable salt of hydrocodone and at least one pharmaceutically acceptable excipient and providing a controlled release of hydrocodone,the dosage form providing an in-vitro release of from at least 18% to about 42.5% by weight of hydrocodone from the dosage form at one hour when measured by the USP Basket Method at 100 rpm in 700 ml of Simulated Gastric Fluid (SGF) for 55 minutes at 37°
C. and thereafter switching to 900 ml of Simulated Intestinal Fluid (SIF) at 37°
C., andafter a first administration to a human, providing a plasma concentration of hydrocodone of at least 8 ng/ml at from about 2 to about 8 hours after administration and a plasma concentration of hydrocodone of at least 6 ng/ml at about 12 hours after administration, based on oral administration of a dosage form containing 15 mg hydrocodone bitartrate,a C12/Cmax hydrocodone ratio of 0.55 to 0.85 anda Tmax of hydrocodone at from about 2 to about 8 hours, whereinthe therapeutically effective amount of the pharmaceutically acceptable salt of hydrocodone is from about 5 mg to about 60 mg, andthe salt of hydrocodone is an inorganic salt of hydrocodone or a bitartrate salt of hydrocodone.

Abstract
A solid oral controlled-release oral dosage form of hydrocodone is disclosed. The dosage form comprising an analgesically effective amount of hydrocodone or a pharmaceutically acceptable salt thereof, and a sufficient amount of a controlled release material to render the dosage form suitable for twice-a-day administration to a human patient, the dosage form providing a C12/Cmax ratio of 0.55 to 0.85, said dosage form providing a therapeutic effect for at least about 12 hours.
