Embodiment 1

[0161] [Example 1] Tablets of compound A containing trometamol as a basic amine

[0162] dosage form

[0163] The 60 mg tablet of Compound A containing tromethamine was prepared according to the dosage forms described in Table 1, Table 2 and Table 3. Tablets of other doses are prepared proportional to the dose according to the weight % of each ingredient. Tablets containing other basic amines such as triethanolamine, diethanolamine, monoethanolamine, etc. are prepared in a similar manner to the dosage form in tromethamine. In fact, tablets can be prepared by substituting other basic amines for tromethamine in Table 1, Table 2 and Table 3.

[0164] Manufacturing method 1

[0165] Each compound A that was ground through a 0.006-inch wheel sieve at 1800 rpm, tromethamine and mannitol both of which were ground through a 0.018-inch wheel sieve at 1800 rpm were weighed. Avicel PH102 was added to the PK-blender and blended for 1 minute to coat the surface. Compound A, milled tro...

Embodiment 2

[0181] [Example 2] Capsules of compound A containing trometamol as a basic amine

[0182] dosage form

[0183] 60 mg capsules of Compound A containing trometamol were prepared in the dosage form described in Table 4. Capsules of other doses are prepared in proportion to the dose according to the weight % of each ingredient. Capsules containing other basic amines such as triethanolamine, diethanolamine, monoethanolamine, etc. are prepared by a method similar to the dosage form in tromethamine. In fact, capsules were prepared by substituting other basic amines for trometamol in Table 4.

[0184] Manufacturing method

[0185] Mill Compound A, trometamol, lactose monohydrate, microcrystalline cellulose PH102, hydroxypropylmethylcellulose and cross- Sodium carboxymethyl cellulose for blending. A solution of polysorbate 80 dissolved in purified water was added to the granulator. The granular material was milled through a 0.25 inch wheel screen and dried on trays. The granular...

Embodiment 3

[0189] [Example 3] Tablets of compound A containing meglumine as a basic amine

[0190] dosage form

[0191] Tablets were prepared using meglumine instead of trometamol as described in Table 3.

[0192] Manufacturing method

[0193] Tablets were prepared by a method similar to Production Method 3 in Example 1. In fact, meglumine was used instead of trometamol as described in Table 3 to prepare 60 mg tablets of Compound A containing meglumine.

Abstract

The present invention provides a medicinal composition capable of preventing a decrease in the blood exposure level of a third generation coxib drug, a method for preparing the composition and utilization of the same. It was discovered that, by adding a basic amine or a basic amino acid or cyclodextrin to a third generation coxib compound, a medicinal composition capable of inhibiting a decrease in the blood concentration thereof, a decrease in the area under concentration thereof and a decrease in the bioavailability thereof can be obtained. In addition, the medicinal composition according to the present invention is highly stable and useful as a medicine. That is, a technical idea that a decrease in blood concentration, a decrease in area under concentration and a decrease in bioavailability can be inhibited by adding a basic amine or a basic amino acid or cyclodextrin is thus established.

Description

technical field [0001] The present invention relates to a composition containing a compound represented by chemical formula (I) or a pharmaceutically acceptable salt thereof, a preparation method of the pharmaceutical composition and an application for treating diseases mediated by cyclooxygenase-2 . [0002] [0003] (Explanations in chemical formulas will be described later) Background technique [0004] Prostaglandins play an important role in inflammation and inhibit the production of prostaglandins especially PGG 2 、PGH 2 and PGE 2 The generation of anti-inflammatory agents has become a common goal in the development. However, commonly used non-steroidal anti-inflammatory drugs (NSAIDs) that act to reduce prostaglandin-induced pain and swelling associated with inflammatory processes also act on other prostaglandin-regulated processes not associated with inflammatory processes. Thus, the use of the most commonly used NSAIDs at higher doses produces side effects s...
