Problems solved by technology

However, due to the poor fluidity and compressibility of solifenacin succinate, and the clinical dosage of solifenacin succinate is relatively small, each tablet of marketed products contains 2.5mg, 5mg, 10mg, which poses a higher technical challenge to quality standards such as full powder direct compression to ensure product content uniformity
There is no report on the preparation of solifenacin succinate tablets by direct compression of all powders

Embodiment 1-5

[0022] The prescription quantity of raw and auxiliary materials of solifenacin succinate tablet in embodiment 1-5: (unit: g)

[0023]

[0024] The preparation of the above examples includes the following steps: 1) Take each raw material in proportion, mix the auxiliary materials evenly and pass through an 80-mesh sieve; 2) Mix the main ingredients and auxiliary materials evenly according to the "equal volume increasing method": take all the main ingredients and an equal amount of For excipients, place them in a mixing machine and mix evenly, then add the same amount of excipients as the mixture and mix evenly, so that the amount is increased until the excipients are added, and the mixing time is 10 minutes each time; Direct compression in a high-speed rotary tablet press.

Abstract

The invention belongs to the technical field of pharmaceutical preparations, and in particular relates to a solifenacin succinate tablet capable of powder direct compression and a preparation method thereof. The mass percent composition of the tablet is: 1-10% of solifenacin succinate, 10-90% of filler, 3-20% of disintegrant, 0.5-5% of lubricant and 0-5% of glidant. The invention solves the defect that the prior art cannot be directly compressed into tablets, and realizes the prescription and process of direct compression of all powder of solifenacin succinate tablets, making the preparation process simpler and suitable for large-scale production.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical preparations, and in particular relates to a solifenacin succinate tablet capable of powder direct compression and a preparation method thereof. Background technique [0002] Solifenacin Succinate, developed by Japan Astellas Pharmaceutical Co., Ltd., is a competitive muscarinic receptor antagonist with a higher selectivity for bladder than salivary gland. Muscarinic M3 receptors play an important role in several primarily cholinergic-mediated functions, including contraction of bladder smooth muscle and stimulation of salivation. Solifenacin succinate inhibits the overactivity of the detrusor muscle by blocking the muscarinic M3 receptors of bladder smooth muscle, thereby alleviating the symptoms of urge incontinence, urgency and frequency associated with overactive bladder. Treatment of urinary incontinence and / or urinary frequency and urgency in patients with overactive bladder (Overact...
