  • Publication number: 20120283283
    Abstract: Methods for detecting enhanced risk of opioid-induced respiratory dysfunction in patients with normal levels of oxygen saturation. The method may comprise: (1) assaying blood of the patient for a normal level of oxygen saturation; (2) measuring the patient's respiration rate at rest for a normal rate; and (3) correlating the normal level of oxygen saturation and the normal rate of respiration with enhanced risk of opioid-induced respiratory dysfunction if: (a) the patient is at an altitude of about 1000 feet above sea level or greater; or (b) the patient's oxygen saturation level is normal but no greater than about 95%; or (c) the patient received prior dosing with intravenous opioid and is converted to dosing with an oral opioid. The method may further comprise administering opioids to a patient after detecting whether there is an enhanced risk of opioid-induced respiratory dysfunction.

  • Patent number: 8222267
    Abstract: A method of converting a treatment for pain comprising intravenous administration of opioids, to a treatment for pain comprising oral administration of a first dose of an immediate release morphine-oxycodone combination in patients in need of analgesia. The method may comprise (1) determining a four-hour average oral morphine equivalents, a one-hour average oral morphine equivalents, or determining a net average hourly intravenous dose, and (2) orally administering to the patient a first dose of a morphine-oxycodone combination in a 3:2 ratio by weight every four to six hours. Also, a method of treating pain in patients who had been administered opioids intravenously, comprising using a dosing algorithm to determine the first dose of the immediate release morphine-oxycodone combination.
