Summary for Patent: 10,028,946

Title:	Treating pain in patients with hepatic impairment
Abstract:	An extended release composition for an analgesic active pharmaceutical ingredient which may be an opioid, preferably hydrocodone as the only active ingredient. The extended release composition preferably comprises a extended release composition which may be in the form of beads contained in an oral dosage form such as gelatin capsules. The composition is designed to release hydrocodone in a way such that the increase in hydrocodone exposure in hepatically impaired patients is not clinically significant. The oral dosage units are supplied as part of a kit, which also includes a primary package and a package insert all sold as a commercially marketed product. The primary package and package insert are contained in an optional secondary package and the package insert does not contain a warning, a dosing instruction, or a dosing table specifically directed to patients suffering from mild, moderate or severe hepatic impairment, and preferably explicitly states that dosing adjustment is not required for mild or moderate hepatic impairment.
