Definitions
- the present invention relates to a pharmaceutical composition containing a salt of scopolamine and / or a hydrate thereof as an active ingredient.
- Scopolamine is widely known as an anticholinergic drug, and is a drug having effects such as suppressing oral and respiratory endocrine secretion and preventing harmful parasympathetic reflexes. So far, pharmaceutical products containing scopolamine as an active ingredient have been developed. For example, in Japan, “Hisco (registered)” is an injection containing scopolamine hydrobromide hydrate, which is a salt of scopolamine, as an active ingredient. "Subcutaneous injection, Kyorin Pharmaceutical Co., Ltd.” manufactures and sells "Transderm Scop (registered trademark), Novartis", which is a patch containing scopolamine free base as an active ingredient, overseas.
- lipid bilayer As is widely known, there is a lipid bilayer around the cell, which acts as a barrier that limits the permeability of substances inside and outside the cell, and of course, water-soluble substances are lipid bilayers. Is difficult to permeate, and fat-soluble substances easily permeate the lipid bilayer. Therefore, except for injections that can avoid the barrier function of the living body such as mucous membranes and epidermis with a lipid bilayer, in general, drugs with high lipophilicity are absorbed intracellularly rather than drugs with high water solubility. Easy to transfer to the blood. Scopolamine hydrobromic acid hydrate, which is a salt of scopolamine, is highly water-soluble and must be a highly lipophilic free base in order to translocate into the cell.
- the drug is preferably in a salt state from the viewpoint of handling and chemical stability.
- chemical stability indicates the stability of a compound with respect to decomposition
- physical stability indicates the stability of a compound with respect to crystal precipitation.
- an absorption promoter other than an acid is used for a composition containing a compound that causes a decomposition reaction catalyzed by an acid. Shows a method for improving absorption into a living body without deteriorating chemical stability. However, there is no mention of a method for resolving the deterioration of chemical stability caused by factors other than acid.
- Patent Document 2 shows a method for improving the absorption into a living body without deteriorating the chemical stability and physical stability of scopolamine by using a composition containing no vinyl acetate and a polar component. , There is no mention of a method of resolving the deterioration of chemical stability in compositions containing polar components.
- a salt of scopolamine is used from the viewpoint of handling and chemical stability, in order to obtain a pharmaceutical composition having excellent absorption of scopolamine into a living body, the salt of scopolamine is used as a free base of scopolamine during production or in the pharmaceutical composition.
- the patented method cannot be applied because it is necessary to contain a base which is a polar component for the purpose of.
- Patent Document 3 Patent Document 4 and Patent Document 5 show a method of improving the physical stability of scopolamine to maintain or improve the absorption into a living body, but the method of improving the chemical stability is described. I haven't suggested it either.
- Patent No. 4081139 Special table 2009-528357 U.S. Pat. No. 4832953 Patent No. 4466977 Patent No. 5695562
- the present invention has been made in view of the above problems, and contains a salt of scopolamine and / or a hydrate thereof, which has high absorption of scopolamine into a living body and is also excellent in chemical stability of scopolamine. It is an object of the present invention to provide a pharmaceutical composition to be used.
- polyvinylpyrrolidone is contained in a pharmaceutical composition containing a salt of scopolamine and / or a hydrate thereof as a free base during production or in a pharmaceutical composition. It was clarified that the high scopolamine absorption into the living body was maintained and the chemical stability was improved. As described in Patent Document 5, polyvinylpyrrolidone improves the physical stability of scopolamine. In general, the dissolved and amorphous states are chemically unstable as compared to the crystalline state. Therefore, the inclusion of polyvinylpyrrolidone in the pharmaceutical composition is considered to be disadvantageous in terms of the chemical stability of scopolamine.
- the present inventors have increased the chemical stability of scopolamine by using an amine compound as a base for making a salt and / or a hydrate thereof of scopolamine a free base during production or in a pharmaceutical composition. It was revealed that it would be improved. That is, polyvinylpyrrolidone is contained in a composition containing a salt of scopolamine and / or a hydrate thereof, and an amine compound is used as a base for making the salt of scopolamine and / or its hydrate a free base. As a result, they have found that it is possible to obtain a pharmaceutical composition having high absorption of scopolamine into a living body and improved chemical stability of scopolamine, and completed the present invention.
- the pharmaceutical composition of the present invention (hereinafter referred to as "the composition of the present invention”) has high absorption of scopolamine into a living body and effectively suppresses the decomposition of scopolamine, so that the pharmacological effect of scopolamine is effective. Moreover, it can be used continuously.
- composition of the present invention contains the active ingredient scopolamine ((-)-(S) -3-hydroxy-2-phenylpropionic acid (1R, 2R, 4S, 7S, 9S) -9-methyl-3-oxa-9).
- scopolamine ((-)-(S) -3-hydroxy-2-phenylpropionic acid (1R, 2R, 4S, 7S, 9S) -9-methyl-3-oxa-9).
- -A pharmaceutical composition containing a salt of azatricyclo [3.3.1.0 2,4 ] non-7-yl ester) and / or a hydrate thereof, polyvinylpyrrolidone and a base.
- Examples of the scopolamine salt used in the composition of the present invention include acid addition salts with an inorganic acid or an organic acid, and specific examples thereof include hydrochloride, hydrobromide, nitrate, phosphate, and sulfuric acid. Salts, acetates, ascorbates, benzoates, cinnaceates, citrates, formates, fumarates, glutamates, lactates, maleates, malate, malonates, mandelates, Examples thereof include methanesulfonate (mesylate), phthalate, salicylate, stearate, succinate, tartrate, propionate, butyrate, pamoate, p-toluenesulfonate (tosylate) and the like. However, it is not limited to these. In the composition of the present invention, it is preferable to use scopolamine hydrobromic acid salt and / or scopolamine hydrobromic acid hydrate.
- the composition of the present invention may contain a therapeutically effective amount of a salt of scopolamine and / or a hydrate thereof, and the state thereof is not particularly limited, but the dissolved state and the amorphous state are considered from the viewpoint of absorption into a living body. preferable. It is important to include a certain amount of the active ingredient in the composition in order to allow the patient to administer a therapeutically effective amount of the active ingredient.
- the content of the salt of scopolamine and / or its hydrate in the composition of the present invention is 0.5 to 10% by mass, preferably 1 to 8% by mass, and more preferably 3 to 6% by mass with respect to the entire composition. Is. If it is less than 0.5% by mass, the therapeutic effect may not be sufficient, while if it exceeds 10% by mass, it may be economically disadvantageous.
- the composition of the present invention contains polyvinylpyrrolidone to improve the chemical stability of scopolamine.
- polyvinylpyrrolidone having a weight average molecular weight of several thousand to several million exists, but the weight average molecular weight of polyvinylpyrrolidone used in the composition of the present invention is not particularly limited.
- One or more of these polyvinylpyrrolidones can be used.
- the content of polyvinylpyrrolidone in the composition of the present invention is in the range of 0.3 to 12% by mass, preferably 0.5 to 10% by mass, and more preferably 1 to 8% by mass with respect to the entire composition. If it is less than 0.3% by mass, a sufficient effect of improving chemical stability may not be obtained, while if it exceeds 12% by mass, it may adversely affect the physical properties of the composition, which is not preferable. is there. Further, if the mass ratio of polyvinylpyrrolidone to the salt and / or its hydrate of scopolamine is 2 or more, the uniformity of the composition may be adversely affected. Therefore, polyvinyl to the salt and / or its hydrate of scopolamine.
