An oral disintegrating tablet of nicergoline contains nicergoline and auxiliaries including sorbitol, methylacryl copolymer resin (Eudragit L30D), citric acid, sodium dicarbonate, magnesium stearate, SiO2 and lemon perfume.

Description

technical field [0001] The invention relates to a dosage form of medicine, in particular to a nicergoline oral disintegrating agent and a preparation method thereof. technical background [0002] Oral disintegrating agents are very necessary for those who have difficulty swallowing, especially the elderly, children and the environment where water is inconvenient. Play a role. Orally rapidly disintegrating tablets are high-porosity oral preparations prepared by the British Weyth Company (Weyth) using freeze-drying technology in the late 1970s, and developed rapidly in the 1990s. Nicergoline has α-receptor blocking effect and vasodilator effect, which can strengthen the energy metabolism of brain cells, increase the utilization of oxygen and glucose; promote the conversion of neurotransmitter dopamine to increase nerve conduction, and strengthen the synthesis of brain proteins , good brain function. It is mainly used to improve cerebral arterioscler...
