Abstract

The present invention belongs to the field of medicine preparation, and relates to one kind of quick disintegrating and leaching tablet containing puerarin as active component. Puerarin as active component is mixed with disintegrating agent, stuffing, corrective, lubricant, effervescent agent, adhesive and coloring agent, and the mixture is pressed into the quick disintegrating and leaching tablet. Each tablet contains puerarin in 10-100 mg, disintegrating agent in 2-20 wt% and co-solvent 1-10 wt%. The tablet of the present invention can disintegrate in 1 min after contacting with saliva in oral cavity and leach out 80 % over in 3 min.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations and relates to a rapidly disintegrating and rapidly dissolving tablet, in particular to a rapidly disintegrating and rapidly dissolving tablet containing puerarin as an active ingredient. Background technique [0002] Orally fast-disintegrating tablet (orally rapidly-disintegrating tablet, ororally rapidly-disintegrating tablet) is a new pharmaceutical preparation that has emerged at home and abroad in the past ten years. features. Orally rapidly disintegrating tablets can be administered without water and with only a small amount of saliva. Generally speaking, orally rapidly disintegrating tablets should disintegrate within 1 minute after contacting saliva in the oral cavity. After disintegration, the drug is rapidly dissolved or dispersed into small particles, which speeds up the absorption and makes the onset of effect rapid. This dosage form is suitable for: (1) patients with swall...
