[0045] Preparation Process:

[0046] Through experiments on ethanol and water, it was found that the solubility of donepezil hydrochloride in hot water is greatly improved, and it does not precipitate after cooling, so hot water is used for dissolution.

[0047] Firstly, dissolve donepezil hydrochloride in 5ml of water, put it in a water bath at 60°C, and stir to make it fully dissolved, then granulate this solution with a soft material made of mannitol, granulate with a 30-mesh sieve, dry at 60°C, granulate with a 20-mesh sieve, add PVPP, Mix L-HPC and aspartame, add magnesium stearate, mix and compress into tablets.

The donepezil hydrochloride orally disintegrating tablet can be used for treating Alzheimer's Association.

Description

technical field [0001] The invention relates to a donepezil hydrochloride orally disintegrating tablet and a preparation method thereof, in particular to an orally disintegrating tablet with donepezil hydrochloride as the main ingredient and a preparation method thereof. The donepezil hydrochloride orally disintegrating tablet can be used for treating Alzheimer's disease. Background technique [0002] Donepezil Hydrochloride (Donepezil Hydrochloride) is the second generation of cholinesterase inhibitor (AChEI) for the treatment of Alzheimer's disease. The content of acetylcholine in the synapses directly involved in neurotransmission is increased, which produces therapeutic effects and can improve learning disabilities. It has almost no inhibitory effect on acetylcholinesterase in the heart and intestines, so it has strong selectivity, long acting time, small side effects, and no liver Toxicity and other characteristics. It is an ideal drug for the treatment of Alzheimer's ...
