[SUMMARY OF THE INVENTION]
[Problems to be Solved by the Invention]
While compound A and a salt thereof are stable to
temperature, humidity and the like when they are alone and in a
solid state, the present inventors have found a problem that a
decomposed product of compound A or a salt thereof increases
chronologically when compound A or a salt thereof is formulated
as a solid preparation (e.g., tablet) according to a
preparation formulation containing other components.
The present invention aims to solve such newly-found
problem, and the present invention aims to provide a solid
preparation (e.g., tablet) showing improved stability of
compound A and a salt thereof in the solid preparation, and a
method of stabilizing compound A and a salt thereof in a solid
preparation.
[Means of Solving the Problems]
As a result of intensive studies conducted in an attempt
to solve the aforementioned problems, the present inventors
have found that chronological decomposition of compound A and a
salt thereof in a tablet is suppressed by setting the content
of compound A and a salt thereof in the tablet to not less than
mass %; in other words, that compound A and a salt thereof
in a tablet are stabilized.
In addition, as a result of intensive studies conducted
in an attempt to solve the aforementioned problems, the present

comprising adding not less than 25 mass % (preferably not less
than 30 mass %, more preferably not less than 40 mass %) of
compound A or a salt thereof (hereinafter sometimes to be
abbreviated as the method of the present invention).
In the present specification, addition and containing
mean the same and, for example, adding not less than 25 mass %
of compound A or a salt thereof to a tablet means that the
tablet contains not less than 25 mass % of compound A or a salt
thereof.
In the method of the present invention, further addition
of (1) D-mannitol particles having an average particle size of
60 - 500 μm (preferably 60 - 250 μm, more preferably 70 - 200
μm, particularly preferably 80 - 150 μm) or (2) D-mannitol
having an average particle size of 30 - 60 μm {e.g., PEARLITOL

above-mentioned D-mannitol particles is more preferable. D-
mannitol and D-mannitol particles may be used alone or in
combination.
The tablet by the method of the present invention is
prepared in the same manner as in the aforementioned
formulation of the tablet of the present invention. For
example, the amount of the D-mannitol particles or D-mannitol
is analogous to that in the tablet of the present invention.
The method of the present invention may include a step of
confirming the stabilizing effect (e.g., step of measuring the
content of a decomposed product (U-2) of compound A or a salt
thereof in the tablet etc.). The step of measuring the content
of the decomposed product can be performed according to, for
example, the below-mentioned Experimental Example 1.
2. Solid preparation containing compound A or a salt thereof
and a fat and oil-like substance having a low melting point
Another embodiment of the present invention relates to a
solid preparation containing (1) compound A or a salt thereof,
and (2) a fat and oil-like substance having a low melting point,
which is selected from polyethylene glycol, glycerol
monostearate and triethyl citrate (hereinafter sometimes to be
abbreviated as the solid preparation of the present invention).
In the solid preparation of the present invention, the
content of compound A or a salt thereof is preferably not less
than 4 mass % and less than 100 mass %, more preferably 4 - 80
mass %, further preferably 18 - 50 mass %.
Since the solid preparation of the present invention
contains a fat and oil-like substance having a low melting
point, which is selected from polyethylene glycol, glycerol
monostearate and triethyl citrate, it can improve the stability
of compound A and a salt thereof in the solid preparation.
These fat and oil-like substances having a low melting point
may be used alone or two or more kinds thereof may be used in
combination.
In the solid preparation of the present invention, the
content of a fat and oil-like substance having a low melting
point, which is selected from polyethylene glycol, glycerol
monostearate and triethyl citrate is, for example, 0.1 - 10
mass %.
While the preferable range of the above-mentioned content
varies depending on the kind of the fat and oil-like substance
having a low melting point to be added to a solid preparation,
for example, when the above-mentioned fat and oil-like
substance having a low melting point is polyethylene glycol
(e.g., polyethylene glycol 6000), it is, for example, 0.1 - 4.0
mass % (preferably 0.2 - 2.0 mass %, more preferably 0.2 - 1.7
mass %, further preferably 0.2 - 0.4 mass %). When, for example,
the above-mentioned fat and oil-like substance having a low
melting point is glycerol monostearate or triethyl citrate, it
is 0.1 - 10 mass % (preferably, 1.0 - 4.0 mass %).
In the present invention, a fat and oil-like substance
having a low melting point is particularly preferably
polyethylene glycol.
Examples of the polyethylene glycol include polyethylene
glycol having an average molecular weight of 200 – 7000000
(preferably about 6000 - about 120000, more preferably about
8000 - about 100000) (e.g., polyethylene glycol 400 (the
Japanese Pharmacopoeia), and polyethylene glycol 6000 (the
Japanese Pharmacopoeia)), POLYOX WSR N-10 (trade name), POLYOX
WSR N-205 (trade name), POLYOX WSR N-12K (trade name), POLYOX
WSR 303 (trade name), preferably POLYOX WSR N-10 (trade name),
polyethylene glycol 6000, more preferably polyethylene glycol
6000) is preferable. As used herein, polyethylene glycol is a
generic term of compounds represented by the formula
H(OCH CH ) OH wherein n is a natural number (compound wherein n
2 2 n
is not less than 2000 is sometimes referred to as polyethylene
oxide).
Here, polyethylene glycol 6000 is also referred to as
macrogol 6000 in the Japanese Pharmacopoeia (an average
molecular weight thereof is generally said to be 7300-9300). In
addition, polyethylene glycol 6000 is referred to as
polyethylene glycol 8000 in the NATIONAL FORMULARY.
In the present specification, the “average molecular
weight” in the explanation of polyethylene glycol means “number
average molecular weight”.
These fat and oil-like substances having a low melting
point, which are in a solid form or a liquid form, are added to
an active ingredient (compound A or a salt thereof). The
present invention is more advantageously applied to a solid
preparation (granule, tablet and the like, preferably tablet)
produced by molding (granulation, compression molding and the
like).
The solid preparation of the present invention is
generally produced by adding the above-mentioned fat and oil-
like substance having a low melting point to an active
ingredient (compound A or a salt thereof) and molding the
mixture.
The addition is performed by an addition method generally
used for preparations, for example, mixing, kneading, screening,
stirring and the like. For example, a fat and oil-like
substance having a low melting point may be directly added to
the active ingredient and mixed, and a solvent may be further
added and mixed therewith, and the mixture can be kneaded,
granulated and dried by conventional methods.
It is also possible to dissolve a fat and oil-like
substance having a low melting point in a suitable solvent, mix
same with an active ingredient, and knead, granulate and dry
same by conventional methods. Furthermore, a solution
containing a fat and oil-like substance having a low melting
point and a solution containing an active ingredient may be
separately sprayed on a powder of excipient and the like.
As the above-mentioned suitable solvent, a solvent that
does not adversely influence the active ingredient, for example,
water, dimethyl formamide, acetone, ethanol, propyl alcohol,
isopropyl alcohol, butyl alcohol, methylene chloride, and
trichloroethane are used.
After the completion of addition, a tablet can be
produced by a known compression molding means. Compression
molding means compressing under pressurization to give a
desired form, which most generally refers to, for example,
tableting and the like.
The solid preparation of the present invention may

administered orally to mammals (e.g., mouse, rat, rabbit, cat,
dog, bovine, horse, monkey, human).
The solid preparation of the present invention is, for
example, useful for the prophylaxis or treatment of hormone-
dependent diseases (e.g., prostate cancer) and the like.
The dose of the solid preparation of the present
invention varies depending on the severity of symptoms; age,
sex, body weight and sensitivity of the administration subject;
and timing, frequency and the like of administration, and is
not particularly limited as long as the object of the present
invention is achieved. For example, when it is used as an oral

The solid preparation of the present invention is
preferably a tablet and the size thereof varies depending on
the shape of the tablet (e.g., round, caplet, oblong etc.). It
only needs to be a size that can be easily taken by the patients.
As the solid preparation of the present invention, a
tablet containing 40 - 120 mg, preferably 80 mg or 120 mg, of
compound A or a salt thereof based on compound A (free form)
per tablet can be mentioned.
In the solid preparation of the present invention,
compound A or a salt thereof can also be used in combination
with one or more different kinds of medicaments.
In addition, the solid preparation of the present
invention preferably contains D-mannitol particles as an
excipient. The content etc. of the D-mannitol particles in the
solid preparation of the present invention are the same as
those detailedly described in “1. Tablet containing compound A
or a salt thereof at a high content”.
Another embodiment of the present invention relates to a
method of stabilizing compound A or a salt thereof, comprising
adding a fat and oil-like substance having a low melting point,
which is selected from polyethylene glycol, glycerol
monostearate and triethyl citrate to a solid preparation
containing compound A or a salt thereof.
The order of addition of each component is not
particularly limited, and, for example, as mentioned above, a
fat and oil-like substance having a low melting point may be
directly added to an active ingredient (compound A or a salt
thereof) and mixed, and a solvent may be further added and
mixed therewith, and the mixture can be kneaded, granulated and
dried by conventional methods; a fat and oil-like substance
having a low melting point may be dissolved in a suitable
solvent, uniformly mixed with an active ingredient, and kneaded,
granulated and dried by conventional methods; or a solution
containing a fat and oil-like substance having a low melting
point and a solution containing an active ingredient may be
separately sprayed on a powder of excipient and the like.
After the completion of addition, a tablet can be produced by a
known compression molding means.
Specifically, for example, when the solid preparation is
a tablet, compound A or a salt thereof is granulated while
spraying a solution obtained by dissolving or dispersing a fat
and oil-like substance having a low melting point in a solvent
or dispersion medium (e.g., water), and dried to give a
granulated powder, and the obtained granulated powder is
punched to give a tablet.
The solid preparation by the method is prepared in the
same manner as in the aforementioned formulation of the solid
preparation of the present invention. For example, the amounts
of the fat and oil-like substance having a low melting point,
which is selected from polyethylene glycol, glycerol
monostearate and triethyl citrate are analogous to those in the
solid preparation of the present invention.
This method may include a step of confirming a
stabilizing effect (e.g., step of measuring the content of
decomposed product (U-2) of compound A or a salt thereof in the
solid preparation etc.). The step of measuring the content of
the decomposed product can be performed, for example, according
to the below-mentioned Experimental Example 1.

hydroxypropylcellulose and polyethylene glycol 6000 was sprayed
and the mixture was dried to give a granulated powder. The
granulated powder was milled by a milling machine (Power mill
P-3, SHOWA KAGAKUKIKAI Co., LTD.) to give a milled powder.
Croscarmellose sodium and magnesium stearate were added to the
obtained milled powder and they were mixed in a blending
machine (Tumbler 15 L, SHOWA KAGAKUKIKAI Co., LTD.) to give a
mixed powder. The mixed powder was tableted by a rotary
tableting machine (AQUARIUS, Kikusui Seisakusho Ltd.) with a
12.0X8.4 mmφ punch to give core tablets (420 mg per tablet).
The core tablet was placed in a film coating machine
(Doria coater DRC500, Powrex Corporation), a film coating
solution with a composition ratio shown in Table 32-2 was
sprayed and the tablet was coated with a trace amount of
Carnauba wax (0.012 mg per tablet) to give a film coated tablet
(about 435 mg per tablet). The obtained film-coated tablets
were placed in a glass bottle, which was tightly sealed and
preserved at 60 C for 2 weeks.

From the results of this test, it was clarified that, even
when the total amount of the core tablet is 420 mg, the
production of the total decomposed product and decomposed
product U-2 was suppressed by adding a fat and oil-like
substance having a low melting point (particularly,
polyethylene glycol) to the core tablet.
