Examples
Embodiment 1
[0015]
[0016]
[0017] Take the donepezil hydrochloride and pullulan of the prescribed amount, place them in an appropriate container, add 100ml of purified water, stir and dissolve at 50°C, add the prescribed amount of triethyl citrate, citric acid, mannitol, and menthol, and (10000rpm) under high-speed shearing for 3 minutes, repeat 3 times, and stand still under vacuum for 8 hours to remove air bubbles, and then the gel for scraping coating is obtained. Scrape-coat this glue solution on a stainless steel plate with a film coater, and dry it at a temperature between 50°C and 60°C. Then the film agent obtained by scraping is peeled off from the plastic film, cut and packaged to obtain the film agent.
Embodiment 2
[0019]
[0020] Take donepezil hydrochloride and polyvinyl alcohol 0588 of prescription quantity, be placed in appropriate container, add 100ml purified water, after stirring and dissolving at 50 ℃, add triethyl citrate, sodium citrate, mannitol of prescription quantity, at (10000rpm ) under high-speed shearing for 3 minutes, repeated 3 times, and left to stand under vacuum for 6 hours to remove air bubbles to obtain the gel for scraping. Scrape-coat this glue solution on a stainless steel plate with a film coater, and dry it at a temperature between 50°C and 60°C. Then the film agent obtained by scraping is peeled off from the plastic film, cut and packaged to obtain the film agent.
Embodiment 3
[0022]
[0023]
