Abstract
The invention discloses a merariveron sustained-release tablet and a preparation method thereof. The merariveron sustained-release tablet is prepared from the following raw materials in percentage by weight: 5- 20% of merariveron, 10-70% of a skeleton material, 1- 5% of an antioxidant, 0.1-5% of a lubricant, 0-70% of a filler and a proper amount of an adhesive. The merariveron sustained-release tablet adopts a film coating, and thus the stability of the merariveron sustained-release tablet is improved. The sustained-release materials in the merariveron sustained-release tablet reduce influences, on release, of different PH valves. The influences, on the absorption of the merariveron sustained-release tablet, of food, are reduced, long-time stable effective drug concentration is kept, and thus the curative effect of the merariveron sustained-release tablet is improved. A patient only needs to take the merariveron sustained-release tablet once a day; the compliance of the patient is improved.
Description
technical field [0001] The invention relates to the technical field of medicine, in particular to a Mirabegron sustained-release tablet and a preparation method thereof. Background technique [0002] In daily life, many people will suffer from such troubles: [0003] Urinary urgency: the urge to urinate comes suddenly and cannot be delayed or tolerated; [0004] Frequent urination: Always need to urinate, more than 8 times a day; [0005] Nocturia: Waking up 2 or more times a night to urinate; [0006] Urge urinary incontinence: Uncontrollable leakage of urine onto clothing following an urgency to urinate.
