Abstract

The invention relates to a method for preparing dry mixture suspending agent, comprising 0.1-35.0% active components, 29.0-99.3% shaping agents, and 0.05-36.4% suspending agents. The preparation comprises that selecting the shaping agents, arranging the shaping agents, holing agents, and disintegration agent into the water to obtain suspending medium; adding active component into suspending medium to obtain the mixture suspending solution; arranging the shaping agent into fluid bed, atomizing drug mixed suspending solution, and drying. Compared with present technique, the invention contains suspending agent, without block and tacky contacted with water. The fluid bed can quickly dry material, with high efficiency and low cost.

Description

technical field [0001] The invention relates to a prescription composition of a pharmaceutical preparation and a preparation method thereof, in particular to a prescription composition of a dry suspension and a preparation method thereof. Background technique [0002] Dry suspension is a fine particle dosage form that has more advantages than solid dosage forms such as tablets. It has a large distribution area in the gastrointestinal tract, fast absorption, high bioavailability, and can avoid the disadvantages of tablets that are difficult to swallow. It not only changes the disadvantages of slow oral absorption of ordinary tablets, which is not conducive to taking by the elderly, children and those with dysphagia, but also enables the drug to exert its curative effect faster and better in the body through the characteristics of easy administration and instant dissolution. The dry suspension is stored in a solid form and is taken orally in the form of a suspension, so it is ...
