Citric acid pentoxyverine tablet and preparation method thereof

The invention discloses a pentoxyverine citrate tablet and a preparation method thereof, and belongs to the technical field of medicine preparation. The talcum powder is mixed with the pentoxyverine citrate raw material in advance, and a powder coating film is formed on the outer layer of the pentoxyverine citrate, so that the pentoxyverine citrate raw material is prevented from being in direct contact with a tabletting stamping die, and the sticking problem in the stamping process is solved. In the granulating process, the moisture content is controlled, the prescription moisture is reduced, part of talcum powder is internally added, and the addition of corn starch is eliminated, so that the problem of lower hardness of the tablet is effectively solved, and the hardness of the tablet is improved. The ratio of the added particle size of the pentoxyverine citrate raw material is controlled, and the sieved and sized raw materials are combined for use, so that the mixing uniformity of the product is ensured, and
