Opioid formulations having extended controlled released

Abstract: Solid controlled-release oral dosage forms comprising a therapeutically effective amount of an opioid analgesic or a salt thereof which provide an extended duration of pain relief of about 24 hours, have a dissolution rate in-vitro of the dosage form, when measured by the USP Paddle Method of 100 rpm in 900 ml aqueous buffer at 37° C. from about 12.5% to about 42.5% (by weight) active agent released after 1 hour, from about 25% to about 55% (by weight) active agent released after 2 hours, from about 45% to about 75% (by weight) opioid analgesic released after 4 hours and greater than about 60% (by weight) opioid analgesic released after 8 hours, the in-vitro release rate being substantially independent of pH and chosen such that the peak plasma level of active agent obtained in-vivo between about 2 and about 8 hours after administration of the dosage form.

Controlled release pharmaceutical dosage forms

Abstract: The present invention relates to pharmaceutical multilayer dosage forms, for example to a tamper resistant dosage form comprising a first layer comprising an active agent and a second layer not comprising said active agent, and processes of manufacture, uses, and methods of treatment thereof providing essentially zero order release

The economic burden of diagnosed opioid abuse among commercially insured individuals.

Abstract: The abuse of prescription opioids imposes a substantial public health and economic burden. Recent research using administrative claims data has substantiated the prevalence and cost of opioid abuse among commercially insured individuals. Although administrative claims data are readily available and have been used to effectively answer research questions about the burden of illness for many different conditions, an important issue is the reliability, replicability, and generalizability of estimates derived from different databases. Therefore, this study sought to assess whether the findings of a recently published study of opioid abuse in a commercial claims database (original analysis) could be replicated in a different commercial claims database. The original analysis, which analyzed the prevalence and excess health care costs of diagnosed opioid abuse in the OptumHealth Reporting and Insights Database, was replicated by applying the same approach to the Truven MarketScan Commercial Claims and En...
