A compression-moldable composition comprising an active ingredient, an excipient and an oily or fatty substance having a lower melting point of about 20 to 90°C is compression-molded into uncoated tablets without coating to improve the abrasion resistance. The oily or fatty substance includes a higher fatty acid or a salt thereof, a wax, a fatty acid ester, a hardened oil, a polyalkylene oxide, etc., and the amount thereof is about 0.01 to 10% by weight. The composition may comprise (1) a granulated powder containing the active ingredient and the excipient, and the powdery or granular oily or fatty substance having a lower melting point, or (2) a granulated powder containing the active ingredient, the excipient and said oily or fatty substance. Compression-molding of the composition improves the abrasion resistance of the tablet and significantly inhibits the development of powder by wearing or abrasion even when the oily or fatty substance is used in a small amount of about 0.1 to 0.5% by weight.
一种由活性成分、赋形剂和熔点较低的油性或脂肪性物质(熔点约为 20 至 90°C)组成的可压模塑组合物,可压模塑成无包衣片剂,无需包衣以提高耐磨性。油性或脂肪性物质包括高级脂肪酸或其盐、蜡、脂肪酸酯、硬化油、聚环氧烷等,其用量约为 0.01 至 10%(按重量计)。组合物可包括:(1) 含有活性成分和赋形剂的粒状粉末,以及具有较低熔点的粉状或粒状油性或脂肪物质;或 (2) 含有活性成分、赋形剂和所述油性或脂肪物质的粒状粉末。即使油性或脂肪性物质的用量较少,约为 0.1%至 0.5%(按重量计),该组合物的压缩成型也能提高片剂的耐磨性,并显著抑制因磨损或磨蚀而产生的粉末。
