    摘要: A process for the preparation of a particulate material by a controlled agglomeration method, i.e. a method that enables a controlled growth in particle size. The method is especially suitable for use in the preparation of pharmaceutical compositions containing a therapeutically and/or prophylactically active substance which has a relatively low aqueous solubility and/or which is subject to chemical decomposition. The process comprising i) spraying a first composition comprising a carrier, which has a melting point of about 5° C. or more which is present in the first composition in liquid form, on a second composition comprising a material in solid form, the second composition having a temperature of at the most a temperature corresponding to the melting point of the carrier and/or the carrier composition and ii) mixing or others means of mechanical working the second composition onto which the first composition is sprayed to obtain the particulate material.
