摘要: A discrete solid orally deliverable pharmaceutical dosage form comprises a plurality of zones, wherein (a) at least one zone comprises an NSAID; (b) at least one zone, other than a zone comprising the NSAID, comprises HPMC having dispersed therein a prostaglandin type compound in a form of a substantially water-free solid dispersion; (c) the plurality of zones are spatially arranged such that, if there is only one NSAID-containing zone and one prostaglandin-containing zone, these zones are arranged other than as a core and mantle respectively separated by an enteric coating layer; and (d) the HPMC comprises a fraction having particle size smaller than about 53 μm, said fraction exhibiting, upon dissolution in C02-free purified water to form a 1% weight/volume solution, a pH not lower than about 4. An assay method is also provided for selecting suitable lots of HPMC for use in preparing such a dosage form.
