The invention discloses a pharmaceutical preparation and use thereof. The preparation includes a first active component, a second active component and pharmaceutically acceptable excipients, wherein the first active component is at least one selected from the group consisting of a neutral endopeptidase inhibitor and a precursor, an active metabolite, a stereoisomer, a pharmaceutically acceptable salt, a prodrug and a solvate thereof. The second active component is at least one selected from the group consisting of a compound represented by the following formula (I) or a precursor, an active metabolite, a stereoisomer, a pharmaceutically acceptable salt, a prodrug and a solvate thereof. The pharmaceutically acceptable excipients include one or more disintegrants and/or one or more fillers. The preparation can ameliorate the problem that conventional excipients cannot effectively dissolve out the active ingredients.
