Abstract

The invention relates to a huperzine A oral formulation and a preparation method thereof. The formulation is prepared from huperzine A and officinal auxiliary materials, wherein the officinal auxiliary materials comprise water-insoluble excipient, disintegrant, adhesive and lubricant. The formulation is prepared from the following components by weight percentage: 0.005-1% of huperzine A, 0.1-99% of water-insoluble excipient, 0.1-10% of adhesive, 0.1-80% of disintegrant and 0.1-10% of lubricant. The invention improves the compliance of patients on the medicament and enhances the bioavailability of the medicament.

Description

technical field [0001] The invention relates to a dosage form of medicine, in particular to an oral preparation of huperzine A and a preparation method thereof. Background technique [0002] At present, about 400 million people in the world have entered the old age among the more than 5 billion people in the world. In the next 50 years, the number of the elderly will increase exponentially. Taking the United States as an example, by 2005, the elderly over 65 years old will account for 16% to 22% of the total population, that is to say, the number of people over 65 years old in the United States will increase from 1 / 9 in the past to 1 / 5. Of these people, about 12 percent have some form of learning and memory impairment, and there are about 5 million potential patients in the United States. In my country, 3.2% of the elderly over 60 years old suffer from this disease. As the world's population ages, the disease is one of the top three causes of disability in the elderly. Ho...
