Abstract

The invention provides a dronedarone hydrochloride pharmaceutical composition which is suitable for the sublingual administration, can quickly run, and can greatly improve the bioavailability and the curative effect. The pharmaceutical composition consists of 5-65 parts of dronedarone hydrochloride, 1-10 parts of a disintegrating agent, 10-80 parts of filler, 0.5-3 parts of antacid, 0-5 parts of corrigent, 1-10 parts of an adhesive and 0.3-2 parts of a lubricating agent. The invention further provides a preparation method suitable for the industrial production. The dronedarone hydrochloride pharmaceutical composition provided by the invention is directly absorbed by the sublingual mucosa, and the first-pass effect of oral medicaments can be avoided, and the gastrointestinal digestion, acidolysis and the like can be avoided, so that the bioavailability can be greatly improved. The epithelium of the sublingual mucosa is not cornified, so that the dronedarone hydrochloride pharmaceutical composition is large in superficial area, and high in infiltration capacity. The medicament can be quickly absorbed after being administrated, so that the dronedarone hydrochloride pharmaceutical composition is quick to run, and convenient to use; and compared with the other administrated preparations, the dronedarone hydrochloride pharmaceutical composition is convenient to administrate, and good in patient compliance.

Description

technical field [0001] The invention belongs to the field of medicine, in particular to a dronedarone hydrochloride pharmaceutical composition and a preparation method. Background technique [0002] The chemical name of Dronedarone is N-[2-butyl-3-[4-[3-(dibutylamino)propoxy]benzoyl]-5-benzofuryl]methanesulfonyl Amidobenzofuran, formula C 31 h 44 N 2 o 5 S, molecular weight 593.22. The chemical formula is as follows: [0003] [0004] Dronedarone hydrochloride is an arrhythmia drug developed by Sanofi-Aventis. This product is a benzofuran derivative that does not contain iodine. Its structure and characteristics are similar to iodamine, but it does not contain iodine and has low lipophilicity. After taking it, phospholipids will not be deposited in the lungs, so the adverse reactions outside the cardiovascular system Iodoamine is less and clinically well tolerated. The half-life of this product is 1-2 days, which is more conducive to adjusting the dosage of the dru...
