A pharmaceutical oral controlled release multiple-units formulation in which the individual units comprise coated units containing an active substance which is subject to controlled release as a result of coating of the units with a water-insoluble, but water-diffusable controlled release coating, the units additionally comprising particles of an active substance adhered to the surface of the controlled release coating in a substantially uniform layer, the particles being at least one power of ten smaller than the coated units. The active substance in the units may be potassium chloride, and that adhered to the surface of the controlled release coating may be a diuretic. |
