Solid particulate dispersions of pharmaceutical agents in a matrix of a watersoluble polymer exhibiting good aqueous dissolution enhanced bioavailability. The method of the invention utilizes water-soluble polymers such as polyvinylpyrrolidone, hydroxypropyl cellulose or hydroxypropylmethyl cellulose as carriers. The invention provides for mixing or extracting the active ingredients in solid particulate form with the polymeric carrier at a temperature at which the polymer softens, or even melts, but the drug remains solid or crystalline. The drug particules thus become coated and produce a product that is matrix coated, i.e. a particulate dispersion.
