The present invention provides a method of making solid micropellets of which at least 75% by weight have a diameter less than 500 µm comprising (i) melting one or more binders； and (ii) combining the one or more binders melted in step (i) with a pharmaceutically active ingredient to form solid micropellets. Solid micropellets obtainable by this method are also provided. The invention has particular utility for improving the solubility of poorly water-soluble pharmaceutically active ingredients.
