    • A unit dosage form, such as a tablet for delivering potassium into the body in a controlled release fashion, comprises of a multiplicity of microencapsulated potassium chloride crystals, which are further coated with a plasticized polymer to improve compressibility of the microcapsules. The compressible microcapsules are blended with a compression aid, such as microcrystalline cellulose and a glidant, such as colloidal silicon dioxide, to form controlled release potassium chloride tablets. The tablets may optionally include other excipients such as surfactants and disintegrants. The tablets thus produced exhibit not only high crushing strength and low friability but also release potassium in humans in a desired controlled release fashion similar to commercially available potassium chloride tablets.
    • 单位剂型,例如以控制释放方式将钾输送到体内的片剂,包含多个微胶囊化的氯化钾晶体,其进一步用增塑聚合物涂覆以改善微胶囊的压缩性。 可压缩微胶囊与压缩助剂如微晶纤维素和助流剂如胶体二氧化硅混合,形成控制释放的氯化钾片。 片剂可以任选地包括其它赋形剂,例如表面活性剂和崩解剂。 如此生产的片剂不仅具有高的抗碎强度和低脆性,而且以类似于市售的氯化钾片剂的所需的控制释放方式释放人体中的钾。
