MSIR is a brand name of oral morphine sulfate currently manufactured by Purdue Pharma. MSIR stands for "Morphine Sulfate Immediate Release". It is pronounced "em-es-eye-ar." Roxanol is a brand name of a concentrated oral morphine solution manufactured by Elan Pharmaceuticals.
2/29/08 NOTE: Purdue Pharmaceuticals is no longer a manufacturer of this product; a visit to the news archive pages at Purdue validates this. Only the generic manufacturers remain. Known manufacturers for the 15 and 30 MG strengths of the tablet form are Ethex, Glenmark, and Roxane pharmaceuticals. Unfortunately, the FDA does not require that efficacy of these generics meets the same standard as the original formulation by Purdue. This is an issue for some.
These drugs are often prescribed for patients with chronic pain (e.g., from terminal cancer) who are already taking extended-release formulations of morphine or other opioids, such as Kadian or MS Contin, but require a rescue dose for breakthrough pain.
