Abstract

The invention relates to a cinacalcet hydrochloride containing pharmaceutical composition and a preparation method thereof. The composition contains cinacalcet hydrochloride, a specific surfactant, and other pharmaceutically acceptable excipients such as a filling agent, a disintegrating agent, an adhesive, and a lubricant. In a wet granulation film coating process adopted in the invention, by simplifying auxiliary materials in a preparation formulation, the safety of medication usage is improved, the production process is simplified, the production cycle is shortened, the production cost is reduced, prepared cinacalcet hydrochloride tablets are good in appearance, and the dissolution effect of the tablets is significantly improved.

Description

technical field [0001] The invention relates to the field of pharmaceutical preparations, in particular to a pharmaceutical composition containing cinacalcet hydrochloride and a preparation method thereof. Background technique [0002] The chemical name of Cinacalcet Hydrochloride is N-((1R)-1-(1-naphthyl)ethyl)-3-(3-(trifluoromethyl)phenyl)propan-1-amine Hydrochloride, its structural formula is: [0003] [0004] Cinacalcet hydrochloride has a chiral center and the active ingredient is in the R configuration. Cinacalcet hydrochloride is a white or off-white non-hygroscopic crystalline powder with a stable crystal form at room temperature. The water solubility of this product is very low, but it is very soluble in some organic solvents, such as methanol and ethanol. At the same time, the particle size and crystal form of the raw material have a great influence on the dissolution and bioavailability of the preparation. [0005] Cinacalcet hydrochloride is a calcimimeti...
