Abstract

The invention discloses a process for preparing Cinacalcet hydrochloride tablets or capsules and belongs to the technical field of medicinal preparations. The preparation process comprises performing dry-process granulation according to one formula; and tabletting or filling capsules by using three dosages according to a ratio. The in-vitro release of the Cinacalcet hydrochloride is characterized in that: 40 to 80 percent of Cinacalcet hydrochloride is released within 5 to 10 minutes; 80 to 90 percent of the Cinacalcet hydrochloride is released within 15 to 20 minutes; and 90 to 100 percent of Cinacalcet hydrochloride is released within 30 to 45 minutes. In the process, the procedures are simple and safety, the quality is controllable, the cost is low, and the production period is short. The process is suitable for large-scale industrial production.
