摘要:
A process for the manufacture of particles comprises mechanically working a mixture of a drug and a hydrophobic and/or hydrophilic fusible carrier in a high speed mixture so as to form agglomerates, breaking the agglomerates to give controlled release particles and optionally continuing the mechanical working with the optional addition of a low percentage of the carrier or diluent.

摘要:
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.

摘要:
A solid, oral controlled release pharmaceutical dosage form has a water-soluble active ingredient dispersed in a matrix and releases the active ingredient at such a rate upon administration that the median tmax is 2.5 to 6 hours and the ratio of mean Cmax to mean plasma level of the active ingredient at 24 hours is in the range of 1.5 to 3.5.
摘要:
A controlled release composition including spheroid cores of diltiazem or a pharmaceutically acceptable salt thereof and optionally a spheronizing agent, the cores being coated with a controlled release layer, and a method of manufacturing the same, is disclosed. The spheronizing agent when present is preferably microcrystalline cellulose. Ethylcellulose is a preferred release coating. The controlled release coating preferably contains a plasticizer, a surfactant and a tack-modifier.
