Abstract

The invention discloses an indapamide monolayer osmotic pump sustained-release tablet, which comprises a tablet core and a controlled-release film coating layer, wherein the tablet core contains 0.5-2% of indapamide as a monarch drug, 1-20% of filling agent, 50-90% of penetration enhancer, 1-15% of adhesive, 1-20% of release regulator and 0.5-3% of lubricant; the controlled-release film coating layer comprises a controlled-release film forming material, a plasticizer and / or a pore-forming agent; and the filling agent comprises agar powder.

Description

technical field [0001] The invention relates to an indapamide sustained-release preparation, in particular to an indapamide oral osmotic pump preparation. Background technique [0002] Hypertension is a common and frequently-occurring disease, and it can also cause cardiovascular and cerebrovascular, kidney and other diseases. It is currently one of the diseases that cause the highest human mortality in the world. The use of diuretics to lower blood pressure in humans began in 1948. For a long time, thiazide diuretics have been one of the main forces of antihypertensive drugs, and they have clear curative effects no matter they are used alone or in combination with other antihypertensive drugs. The results of large-scale international clinical trials over the past few decades have further confirmed its position in antihypertensive therapy. Several European and American committees on the management of hypertension have recommended diuretics as the drug of choice for uncompli...
