Solid oral dosage forms, especially tablets, of a pharmaceutical composition comprising a supramolecular complex can be formed from a direct compression process or a compaction process such as roller compaction. Such solid oral dosage forms feature an immediate release profile that allows for fast release of the therapeutic agent. A particularly useful supramolecular complex is trisodium [3-((1S,3R)-1-biphenyl-4-ylmethyl-3-ethoxycarbonyl-1-butylcarbamoyl) propionate-(S)-3'-methyl-2'-(pentanoyl{2"-(tetrazol-5-ylate)biphenyl-4'-ylmethyl}amino)butyrate] hemipentahydrate.本發明係有關一種包含超分子複合物之醫藥組合物之固體口服劑型(尤其錠劑),其可由直接壓縮法或諸如滾壓法之壓實法形成。該等固體口服劑型之特徵為允許治療劑快速釋放之立即釋放型態。尤其適用之超分子複合物為雙倍半水合[3-((1S,3R)-1-聯苯-4-基甲基-3-乙氧羰基-1-丁基胺甲醯基)丙酸-(S)-3'-甲基-2'-(戊醯基{2"-(四唑-5-基)聯苯-4'-基甲基}胺基)丁酸]三鈉。
