Embodiment 1
[0055]Weigh each component according to prescription 1, mix mannitol, lactose monohydrate and erlotinib hydrochloride evenly and pass through a 60-mesh sieve for micronization. The particle size distribution of the mixed material is required to be D10=0.1~5μm, D50=1~15μm , D90<30 μm. Take the mixture that meets the particle size distribution requirements to monitor the content of erlotinib hydrochloride, and convert the ratio in the material; take the mixture with known solid content, put it in the mixer, add microcrystalline cellulose PH101, sodium starch glycolate and mix for 10 minutes; collect material. Take the mixed material and put it on the dry granulator, adjust the rotation speed of the extrusion wheel (3.6~5.3rpm), the rotation speed of the feeding screw (12~24rpm), the pressure of the oil cylinder (the pressure of the oil cylinder is 1.0 MPa~3.0 MPa) to make it three Those who cooperate effectively, until the hardness of the pressed medicine block (1~3kg) is moder...
Embodiment 2~5
[0057] Each component is weighed according to prescription 2-5, and the preparation method is the same as in Example 1.
Embodiment 6
[0059] The dissolution rate measurement of embodiment 1~5 preparation
[0060] Dissolution method: paddle method, 75 rpm, solvent: 0.1mol / L hydrochloric acid solution (1%V / V~SDS) 1000ml.
[0061] At 5min, 10min, 15min, 30min, 45min, and 60min, take 10ml and filter it, dilute it with dissolution medium and measure it; the concentration of the reference solution is 10μg / ml. The drug concentration detection method is UV method; the detection wavelength is 352nm. The dissolution data are shown in Table 2.
