The invention relates to the technical field of pharmaceutical preparations, in particular to a BTK inhibitor
solid tablet and a preparation method thereof.The BTK inhibitor
solid tablet is prepared from, by weight, 4.5-5.5% of a compound shown in the formula I, 80-90% of filler, 1-5% of
adhesive, 3-10% of disintegrating agent and 0.1-5% of
lubricant, and the particle size of the compound shown in the formula I is D90lt; the
dissolution rate of the
solid tablet of the compound shown in the formula I in a medium with the pH value of 1.0 for 15 min is larger than 85%, the
dissolution rate after acceleration is not remarkably changed, and the preparation is simple in process, capable of guaranteeing the stability, convenient to transport and store and suitable for large-scale production.
