Abstract

The invention relates to a pharmaceutical composition containing solifenacin succinate. The pharmaceutical composition is characterized by simultaneously containing direct compression lactose, sodium carboxymethyl starch, a binder and a lubricating agent. The invention also discloses a preparation method, namely a direct powder compression method of the pharmaceutical composition. The pharmaceutical composition and the preparation method thereof are not influenced by water in the preparation process, the pharmaceutical composition is low in impurity content and better in drug dissolubility, and the preparation method is more suitable for industrial production.

Description

technical field [0001] The invention relates to pharmaceutical preparations, in particular to a pharmaceutical composition containing solifenacin succinate and a preparation method thereof. Background technique [0002] Solifenacin Succinate, 1-azabicyclo[2.2.2]octane-8-yl-(1S)-1-phenyl-3,4-dihydro-1H-isoquinoline-2 - formate succinate) is a new generation of M 3 Receptor antagonist, acts on the M receptor on the detrusor muscle, reduces the overactivity of the detrusor muscle, thereby relieving symptoms such as urgency, frequency and urge urinary incontinence caused by overactive bladder muscle, compared with similar drugs , which has the highest selectivity for the bladder, so it has stronger curative effect, fewer side effects, and better tolerance and compliance of patients. The first-line treatment drugs recommended in the treatment guidelines. [0003] The original manufacturer of solifenacin succinate is Astellas Corporation of Japan. The product was first launched...
