Embodiment 1

[0366] Example 1 A kind of dextromethorphan hydrobromide oral dispersible film

[0367] See Tables 21 and 22 for prescriptions.

[0368] Prepared by:

[0369] 1. Dilute 25ml of 1mol / L sodium hydroxide solution to 175ml with purified water, and after mixing evenly, add the prescribed amount of polycridine, the weight / molar ratio of polycridine to sodium hydroxide is 1g : 0.0025mol, stirred for 6 hours;

[0370] 2. Add 8.75ml of ethanol and 2.5g of dextromethorphan hydrobromide to the above suspended solution, stir at room temperature, and react for 12 hours; filter with suction, discard the filtrate, and keep the filter cake;

[0371] 3. Dissolve 2.5 g of dextromethorphan hydrobromide in 175 ml of purified water and stir to dissolve. After dextromethorphan hydrobromide is completely dissolved, add the above filter cake for reaction, stir at room temperature, and react for 10 hours; filter with suction, discard the filtrate, and keep the filter cake;

Abstract

The invention provides a dextromethorphan hydrobromide oral dispersible film agent. The film agent comprises dextromethorphan hydrobromide, polacrilin or polacrilin potassium with grain diameter of 50-150mu m, a film forming agent, a plasticizer, a disintegrating agent, a wetting agent and water, wherein dextromethorphan hydrobromide and polacrilin or polacrilin potassium form a dextromethorphan hydrobromide compound, and the weight ratio of dextromethorphan hydrobromide to polacrilin or polacrilin potassium is 1:1-1:2, and preferably 1:1.3-1:1.5; the film forming agent comprises hydroxypropyl methylcellulose E3 and hydroxypropyl methylcellulose E50. The invention also provides a preparation method of the dextromethorphan hydrobromide oral dispersible film agent. The dextromethorphan hydrobromide oral dispersible film agent can well solve the problem of poor taste of dextromethorphan hydrobromide, is particularly suitable for children and old patients, and can remarkably improve the compliance of patients. An oral film tablet is nicer by an optimal preparation method.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, and in particular relates to a dextromethorphan hydrobromide oral dispersible film and a preparation method thereof.
