Claims32
A method for the production of carrier pellets for a pharmaceutically active substance, the method comprising:
- a) producing a liquid formulation by dissolving, dispersing, or a combination of dissolving and dispersing at least one physiologically well-tolerated pH regulator in at least one solvent or emulsifier;
- b) introducing the liquid formulation into a fluidized-bed or spouted-bed unit using at least one nozzle;
- c) forming essentially spherical carrier pellets by spray granulation in the unit wherein the solvent is evaporated by a drying gas flow;
- and
- d) discharging the carrier pellets from the unit.
A carrier pellet for carrying a pharmaceutically active substance, the carrier pellet comprising at least one physiologically well-tolerated pH regulator, wherein the carrier pellets are produced by the method comprising:
- a) producing a liquid formulation by dissolving, dispersing, or a combination of dissolving and dispersing at least one physiologically well-tolerated pH regulator in at least one solvent or emulsifier;
- b) introducing the liquid formulation into a fluidized-bed or spouted-bed unit using at least one nozzle;
- c) forming essentially spherical carrier pellets by spray granulation in the unit wherein the solvent is evaporated by a drying gas flow;
- and
- d) discharging the carrier pellets from the unit.
