Patent number: 6143328Abstract: Sustained release pharmaceutical formulations containing morphine, or a pharmaceutically acceptable salt thereof, as active ingredient, suitable for administration on a once daily basis, are disclosed. In a first aspect, an orally administrable sustained release unit dosage form gives a peak plasma level at 1.0 to 6 hours after administration. In a second aspect, the formulation provides a W.sub.50 for the M-6-G metabolite for morphine of between 4 and 12 hours. A third aspect concerns the pharmaceutical unit dosage form obtained by compressing multiparticulates comprising a pharmaceutically active substance in a matrix of hydrophobic fusible material having a melting point of from 35 to 150.degree. C.Type: GrantFiled: March 8, 1999Date of Patent: November 7, 2000Assignee: Euro-Celtique, S.A.Inventors: Joanne Heafield, Trevor John Knott, Stewart Thomas Leslie, Sandra Therese Antoinette Malkowska, Ronald Brown Miller, Derek Allan Prater, Kevin John Smith
