The application belongs to the technical field of
medicine, and particularly relates to a
andrographolide anhydrous swallowing granule and a preparation method thereof. The
andrographolide anhydrous swallowing granule is formed by mixing
drug-containing microcapsules and flavoring auxiliaries. The
drug-containing microcapsules are prepared by centrifugal
hot melt spraying technology from
andrographolide and high-melting-point
capsule materials. The high-melting-point
capsule materials are one or more of Brazil palm
wax, hydrogenated
castor oil,
microcrystalline wax,
rice bran wax and sugarcane
wax. The flavoring auxiliaries are fillers, sweeteners, essences and pH regulators. The prepared granule has the characteristics of
small particle size,
smooth surface, good fluidity, no grit feeling, no sticky teeth feeling and easy
swallowing. Moreover, the granule has a significant
taste masking effect, no bitterness, moderate
sweetness and moderate fragrance, which helps to improve
patient compliance, and is particularly suitable for old people and children patients who have difficulty in swallowing. The centrifugal
hot melt spraying technology adopted by the application is simple in process, low in cost, green and
pollution-free, and suitable for large-scale production.
