PROBLEM TO BE SOLVED: To provide excipients which are tablets molded with low pressure, having high hardness, and resistant to cracking, chipping or the like, as well as which have no cost problem of requiring large quantities of particles with special physical properties.SOLUTION: An excipient for tablets comprising mannitol is characterized by that the mannitol is obtained by mixing, at a ratio of 1:99 to 50:50, spherical crystalline particles obtained by spray drying and having a repose angle of 30 to 50 degrees with precipitated crystal particles obtained by crystallizing.SELECTED DRAWING: None【課題】 低成形圧で高硬度かつ割れやカケなどが発生しづらい錠剤であって、特殊な物性の粒子が大量に必要となるコストの面の問題も有さない賦形剤を提供する。【解決手段】 マンニトールからなる打錠用賦形剤であって、該マンニトールが、噴霧乾燥によって得られた安息角が３０～５０度であることを特徴とする球形結晶粒子と、晶析により得られた析出結晶粒子とを、１：９９から５０：５０の割合で混合したものであることを特徴とする打錠用賦形剤。【選択図】なし
