Presented at CPDD 2014. See our poster for Comparing abuse of extended-release versus immediate-release opioid analgesics adjusted for number of prescriptions and morphine-equivalent dose here Abstract. Aims: It has been suggested that abuse risk of extended-release (ER) opioids is greater than immediate-release (IR) opioids, but risk rates vary depending on the denominator Objective: Extended release (XR) and immediate release (IR) quetiapine have differing dosing, titration and plasma concentration proﬁles. The authors assessed whether the use of quetiapine XR and IR in schizophrenia spectrum disorders (SCZ) and bipolar disorder (BD) differ. Design: Retrospective non-interventional registry study Extended-release opioids should be avoided when initiating opioid therapy. 10/325 mg oxycodone/acetaminophen QID is above the recommended threshold of 50 MME/day and would be too high of a starting dose especially in a patient who has never taken opioids
Extended-release metformin showed slightly lower maximum concentrations, longer times to maximum concentration (7-8 vs. 4-5 h), and similar bioavailability compared with immediate-release products . This extended release could potentially reduce dosing frequency to once daily compared with two or three times daily for immediate-release. The geometric mean ratios (metformin extended-release / immediate-release metformin) of AUC 0-24hr , AUC 0-72hr , and AUC 0-inf. for these five studies ranged from 0.96 to 1.08.

Abstract. Objective: Describe different half-life measures and compare immediate- and extended-release topiramate (TPM-IR [Topamax®] and USL255 [Qudexy™ XR]) Background: Clinicians frequently use elimination half-life (t 1/2z; time to decrease drug concentration by half after absorption and redistribution) to determine dosing frequency and time to steady state Both extended-release and immediate-release formulations of febuxostat have demonstrated efficacy and tolerability in individuals with gout and normal or impaired renal function, according to a study recently published in Arthritis & Rheumatology.. The study included 1790 individuals with gout and a history of normal or impaired renal function Researchers at the University of Pavia in Pavia, Italy, have found the drug metformin extended release (XR) formula to be more efficient at controlling Type 2 diabetes than the drug metformin immediate release (IR) formula. In a study reported on in May of 2017 in the journal Drug Design and Developmental Therapy, two hundred and fifty-three people diagnosed with Type 2 diabetes had HbA1c. When switching from the immediate-release (IR) tablets to the extended-release (ER) capsules, the following conversion is recommended: 10 mg twice daily of the IR tablets should be converted to 28 mg once daily of the ER capsules beginning the day after the last dose of the IR tablet
Extended-release quetiapine fumarate (quetiapine XR) is a formulation with similar bioavailability to immediate-release quetiapine fumarate (quetiapine IR) . Quetiapine XR also achieved comparable mean plasma concentrations as quetiapine IR, which was recommended two divided doses regimen, during a 24 h dosing interval when administered once. Furthermore, with trospium 60 mg extended‐release versus 20 mg, median time to maximum plasma concentration is later (5.0 vs 4.5 hours) and half‐life is longer (35.8 vs 27.2 hours). Trospium exposure is lower with multiple dosing of trospium 60 mg extended‐release compared with trospium 20 mg twice daily
