    1.1 Theophylline sustained-release pellets

    a) Formulation

    The formulation is designed for 500g of pure theophylline pellets (Spherofillin [1];diameter 0.8-1.3mm)

    Polymer suspension Kollicoat SR 30 D [1] 223.67gPropylene glycol [1] 6.71gWater 149.86g

    Pigment suspension Kollidon 30 [1] 2.24gTitanium dioxide [2] 2.24gSicovit Red 30 [1] 2.24gTalc [3] 15.66gWater 44.73g

    b) Preparation of the spray suspension

    Polymer suspension Add propylene glycol followed by Kollicoat SR30 D to the given quantity of water with stirring.

    Pigment suspension Dissolve Kollidon 30 in the given quantity ofwater. Add Sicovit Red 30, titanium dioxide andtalc with vigorous stirring and homogenize themixture in a corundum disk mill.

    Spray suspension Incorporate the pigment suspension into thepolymer suspension with stirring. The suspensionmust be stirred during the spraying process toprevent settling.

    Page7/51 Caffeine sustained-release pellets

    c) Coating

    The pellets were coated in an Aeromatic Strea-1 (Aeromatic AG). The suspensionwas sprayed continuously onto the fluidized, pre-heated pellets from the top.

    Process parameters Inlet air temperature 60COutlet air temperature 37CProduct temperature 38CAir flow 80m/hNozzle diameter 0.8mmSpraying rate approx. 11.5g/minSpraying time 39 minAtomizing pressure 1.0barDrying 45C/ 5minCoating weight 2mg film former/cm

    The coating weight of 2mg film former / cm given here was determined from thesurface area of the pellets. Since the particle size distribution and surface structureinfluence the polymer quantity required, calculating the surface area is recommendedas a means of estimating the required coating weight in each specific case.
