Abstract

PURPOSE:To obtain the titled amfenac pharmaceutical, useful as a nonsteroid anti-inflammatory and analgesic agent, and stable with time, by adding a small amount of a specific additive capable of exhibiting the efficacy to the amfenac and amfenac calcium. CONSTITUTION:At least one selected from magnesium oxide, basic magnesium carbonate and calcium carbonate in an amount of 0.1-1 of amfenac and amfenac calcium is added to the amfenac and amfenac calcium to give the aimed substance. This invention provides the aimed pharmaceutical without change in appearance due to the formation of a decomposition product, e.g. color change of a capsule from the yellow contents unique to the amfenac sodium to a light red, the yellow surface of a tablet to red, and the yellow powder of the power to light red, and discoloration on storage under room temperature conditions for one year.

Tablets, granules, fine granules, powders, etc. are considered. In order to manufacture these preparations, generally, for example, the ``Dispensing Guide Commentary''
According to (published by Yakuji Nippo), capsules and tablets*E4
7. Lactose, starch or crystalline cellulose is blended as a lubricant, and magnesium stearate or calcium stearate is added as a lubricant. `` Granules and fine granules may further contain binders such as starch, gelatin, gum arabic, cellulose ethers, polyvinylpyrrolidone, etc., and a small amount of flavoring as a flavoring agent. Flavoring agents may be added as flavoring agents. However, when these Amfenac preparations are manufactured by such known methods, i.e., capsules, tablets, Granules, fine granules, and powders were manufactured using the formulations shown in Formulas 1 to 4 in Table 6 of Example 36, and when each formulation was stored at room temperature for one year, the capsules contained Amfenac. The yellow content derived from sodium changed to pale red, and in the case of tablets, the surface of the yellow color changed to red, and in the case of powders, the yellow powder turned to pale red.Furthermore, in each preparation, amfenac sodium It was confirmed by analysis by thin layer chromatography that 7-penzoyl-2-oxindole, which is the main decomposition product of amfenac calcium, was produced. When produced by the above method, it was thought that it would be difficult to formulate a formulation due to the formation of decomposition products and external malting due to discoloration.

Therefore, as a result of repeated research in order to produce a formulation that is stable over time, the present inventors have discovered that amfenac sodium or amfenac calcium has no medicinal effects such as magnesium oxide, base, magnesium carbonate, and magnesium carbonate. It has been found that a stable preparation that does not discolor over time can be produced by adding one or more selected from calcium.
