The invention provides an
indapamide tablet. The tablet is composed of a tablet core and a
film coating layer, wherein the tablet core is prepared from the following raw materials in parts by weight of 20-30 parts of
indapamide, 600-800 parts of a filler, 100-300 parts of an
adhesive, 8-50 parts of a
lubricant and 2-25 parts of a
glidant; and the
mass of the
film coating layer is 2-5% of the massof the tablet core. A preparation method comprises the following steps of pretreatment of raw materials and auxiliary materials; weighing and proportioning;
dry powder mixing; dry
granulation; total mixing; tabletting; and
coating. According to the invention, dry
granulation is adopted, the operation process is simple, the intra-batch and inter-batch difference is small, the
particle size distribution of
powder is uniform and stable, and the tablet
weight difference and the tablet
hardness in the tabletting process are easy to control; water or an
organic solvent does not need to be added, andhigh-temperature
drying is not needed, so that damage to main active ingredients is small; the
dissolution of the
indapamide tablet is consistent with that of an original
drug; and according to the indapamide tablet prepared by the invention, API distribution is more uniform, and a burst release phenomenon does not easily occur during release.
