Embodiment 1

[0027] Indacaterol tablets are prepared from the following medicinal components:

[0028]

[0029] Preparation

[0030] Indacaterol and lactose are finely powdered at a ratio of 1:20, and set aside; prepare a PVP K90 aqueous solution with a concentration of 15%, and set aside; weigh the prescribed amount of indacaterol, lactose, and starch and mix evenly, add PVP K90 aqueous solution to granulate , dry, add the corresponding prescription amount of magnesium stearate and mix evenly, measure the content of the mixture, calculate the weight of the tablet, and compress the tablet to get final product.

Abstract

The invention belongs to the field of medical technology, and particularly discloses indacaterol tablets and a preparation method thereof. In the invention, active ingredients including indacaterol and lactose are subjected to micropowder treatment, and povidone K90 is added into the prescription as an adhesive to obtain the tablets. By adopting the method, the content uniformity of the obtained preparation meets the requirements, a new option is provided to COPD (chronic obstructive pulmonary disease) patients with different illness characteristics, and the needs for treating asthma and COPD are met to the greatest degree.

Description

field of invention [0001] The invention belongs to the field of medicines, and in particular relates to tablets containing indacaterol and a preparation method thereof. Background of the invention [0002] Indacaterol is a bronchodilator that belongs to the long-acting inhaled β2-adrenergic receptor agonist (LABA) class and is suitable for the maintenance treatment of adult patients with chronic obstructive pulmonary disease (COPD). It takes effect in 5 minutes and lasts for 24 hours. Indacaterol is produced by Swiss Novartis Pharmaceuticals and has been listed in more than 70 countries and regions around the world since 2009; it was approved by the State Food and Drug Administration in June 2012 to be listed in China. It is the first LABA approved for the treatment of COPD in my country class of single preparations. Clinical trials have shown that taking indacaterol once a day can cause bronchodilation for more than 24 hours, and its bronchodilation time is longer than tha...
