Problems solved by technology

In recent years, andrographolide has developed common dosage forms such as tablets, capsules, and dripping pills. However, diterpenoid lactone compounds are difficult to dissolve in water and can only be administered orally
In addition, due to the extremely bitter taste of andrographolide, it is unfavorable for children, the elderly and patients with dysphagia to take medicine. These dosage forms have not solved this problem

Abstract

The invention discloses an andrographolide dry suspension which is particles prepared from andrographolide and accessories by mixing and spraying, wherein the accessories have relatively low melting points and are any two of hexadecanol, octadecanol, glyceryl monostearate, glyceryl behenate, stearic acid, beewax, polyvinyl alcohol and polyethylene glycol; the total mass of the accessories with relatively low melting points is 0.1-10 times that of andrographolide; and the accessories also include at least one other accessory. The andrographolide dry suspension disclosed by the invention is convenient to take simply by adding a little water; and with little bitterness, the andrographolide dry suspension realizes a good taste modifying effect on andrographolide and is suitable for children, old people and patients suffering dysphagia.

Description

Technical field: [0001] The invention relates to a dry suspension of andrographolide and a preparation method thereof. Background technique: [0002] Whether it is chemical medicine or traditional Chinese medicine, the bitter taste of the medicine is one of the reasons why it is not accepted by people. Andrographolide is a diterpene lactone compound, which has the effects of dispelling heat, detoxification, anti-inflammatory and analgesic, and is resistant to bacteria and viruses. Upper respiratory tract infections and dysentery have special effects and are known as natural antibiotics. In recent years, andrographolide has developed common dosage forms such as tablets, capsules, and dripping pills. However, diterpene lactone compounds are difficult to dissolve in water and can only be administered orally. In addition, due to the extremely bitter taste of andrographolide, it is not conducive to taking medicine for children, the elderly and patients with dysphagia. None of these d...
