Embodiment 1

[0025] The preparation of embodiment 1 palonosetron hard capsule

[0026]

[0027] Take the prescribed amount of palonosetron hydrochloride, add 5 times the amount of lactose and mix it, then carry out jet milling, then add 5 times the lactose to the obtained mixed powder and mix evenly, then add the remaining lactose and the prescribed amount of microcrystalline cellulose, carboxymethyl Add sodium starch and mix well, and finally add magnesium stearate and mix well. The obtained powder was sampled at 10 different positions, and an appropriate amount of powder (equivalent to 0.5 mg palonosetron) was weighed at each sampling point, and the moisture content was measured to determine the percentage content of each point. Capsule filling, inspection and packaging are carried out according to the detection results of the intermediate content, and the product is obtained.

Embodiment 2

[0028] The preparation of embodiment 2 palonosetron hard capsules

[0029]

[0030] Take the prescribed amount of palonosetron hydrochloride, add 5 times the amount of lactose and mix it, then carry out jet milling, then add 5 times the lactose to the obtained mixed powder and mix evenly, then add the remaining lactose and the prescribed amount of microcrystalline cellulose, carboxymethyl Add sodium starch and mix well, and finally add magnesium stearate and mix well. The obtained powder was sampled at 10 different positions, and an appropriate amount of powder (equivalent to 0.25 mg palonosetron) was weighed at each sampling point, and the moisture content was measured to determine the percentage content of each point. Capsule filling, inspection and packaging are carried out according to the detection results of the intermediate content, and the product is obtained.

Embodiment 3

[0031] The preparation of embodiment 3 palonosetron hard capsules

[0032]

[0033] Take the prescription amount of palonosetron hydrochloride, add 5 times the amount of lactose and mix it, then carry out jet milling, then add 5 times the lactose to the obtained mixed powder and mix evenly, then add the remaining lactose and the prescription amount of microcrystalline cellulose, carboxymethyl Add sodium starch and mix well, and finally add magnesium stearate and mix well. The obtained powder was sampled at 10 different positions, and an appropriate amount of powder (equivalent to 0.75 mg palonosetron) was weighed at each sampling point, and the moisture content was measured to determine the percentage content of each point. Capsule filling, inspection and packaging are carried out according to the detection results of the intermediate content, and the product is obtained.
