Abstract

The invention discloses a tablet containing olmesartan medoxomil and a preparation method of the tablet. The tablet is composed of olmesartan medoxomil, a disintegrating agent, a filling agent, a diluent, an anti-sticking agent and a lubricating agent. The preparation method disclosed by the invention comprises the following steps: performing jet milling treatment on olmesartan medoxomil, and mixing with the anti-sticking agent to pass through a 30-mesh sieve; mixing with other medicinal auxiliary materials, and directly tabletting; performing film coating on the tablet core after tabletting,wherein the film coating premixed agent is composed of the following materials: hydroxypropyl methylcellulose, titanium dioxide and polyethylene glycol. The olmesartan medoxomil tablet provided by theinvention is high in in-vitro dissolution rate, high in bioavailability, excellent in stability and mechanical strength, less in odor, sticking-free and suitable for large-scale mass production.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical preparations, and in particular relates to an olmesartan medoxomil tablet and a preparation method thereof. Background technique [0002] Hypertension is the most common disease with the highest incidence rate in the world. According to statistics, the number of hypertensive patients in my country has exceeded 100 million, and it is showing a younger trend. Among various cardiovascular and cerebrovascular diseases, the prevalence rate caused by hypertension is the highest. Olmesartan medoxomil tablet is a preparation product with good clinical blood pressure lowering effect developed and widely used in recent years. As a prodrug, it is absorbed through the gastrointestinal tract and rapidly and completely deesterified into olmesartan. Olmesartan is a selective angiotensin II type 1 receptor (AT1) antagonist, which blocks the vasoconstrictive effect of angiotensin II by selectively blocki...
