Randomized Controlled Trial
Factors affecting dosing regimens of morphine sulfate extended-release (KADIAN) capsules.
Although most extended-release morphine formulations are indicated for use once-daily (q24h) or twice-daily (q12h), KADIAN (morphine sulfate extended-release) capsules, which contain polymer-coated, extended-release morphine sulfate pellets, are indicated for q24h and q12h dosing. This analysis identified factors that might impact decisions to choose q24h or q12h regimens for patients with chronic, nonmalignant pain. Data were obtained from a supplemental analysis of the KRONUS-MSP trial, a community-based, open-label, 4-week study in which patients with chronic, nonmalignant pain (N = 1,428) were randomized to KADIAN q24h dosed either AM or PM. ⋯ Results were significant versus baseline for all outcomes. Adverse event rates were similar for the two groups; the most common adverse events were constipation and nausea. Results demonstrate that KADIAN was effective in relieving pain and improving sleep and quality-of-life scores, regardless of whether patients dosed q24h or q12h, and that dosing decisions can be made, based on individual factors, within the first few weeks of therapy.
