Fukangning tablet and preparation method thereof

The invention relates to a Fukangning tablet and a preparation method thereof. The method comprises the following steps: obtaining a Fukangning tablet substrate; and carrying out film coating on the Fukangning tablet substrate, and forming a film layer on the surface of the Fukangning tablet substrate to obtain the Fukangning tablet. A coating liquid used for the film coating includes the following raw materials (by weight): 580-620 parts of hydroxypropyl methyl cellulose, 60-65 parts of talcum powder, 70-80 parts of polyethylene glycol, 130-140 parts of a pigment and 8,500-9,000 parts of water. The technological parameters of the film coating are as follows: the inlet air temperature is 85-100 DEG C, the outlet air temperature is 45-55 DEG C, the spray velocity is 115ml/min-125ml/min, andthe atomization pressure is 0.4 MPa-0.5 MPa. According to the above method, the water-soluble coating liquid is used for film coating on the Fukangning tablet substrate, and a film coating layer is formed on the surface of t
