(57) Abstract:

The proposed new tablets medicine for edema early transient incapacitation and primary reaction to radiation containing 1,2,3,9-tetrahydro-9-methyl-3-[(2-methyl-1H-imidazol-1-yl)methyl]-4H-carbazole-4-one, or its hydrates, or salts thereof (ondansetron, Letran) and benzamide derivative selected from the group ArCONH2where aryl represents unsubstituted phenyl or phenyl substituted at the 3 rd position amino - or allmineral that are in a weight ratio of 1:20-500. The tool has a high activity, high reliability and easy to use.

The invention relates to a new combination drug, which can be used as a means of protecting the person from the early transient incapacitation and edema of the primary reaction to radiation.

Known application of 1,2,3,9-tetrahydro-9-methyl-3-[(2-methyl-1H-imidazol-1-yl)methyl]-4H-carbazole-4-it, or its hydrate, or its salts (I) as a means of acute emetic response caused by the use of drugs or other means of chemotherapy and/or rentgenoterapii tumors or radiation. Most often AA (ondansetron, Letran) Patent of great Britain No. 2153821, 2290963; European patent No. 191562, 219929; the patent of Russia №1528319, 2041876, 2159614 and other Order of the chief of gumu MO of the Russian Federation No. 224 from 01.06.1996 “Of acceptance for the supply of medical services of the Armed forces of the Russian Federation tablets latrine 0,004 coated”).

A disadvantage of the known medicines is the lack of latrine protection from other signs of the primary reaction to radiation and the ability to protect from early transient incapacitation.

The objective of the invention is the creation of a medicinal product for human protection from early transient incapacitation and edema of the primary reaction to radiation in the form of a tablet dosage form (as is most convenient in a military context). The task is dictated by the modern methods of warfare, especially the ability to use in combat so-called tactical nuclear weapons. In these circumstances, military personnel receive significant radiation doses. Unknown to us the means of protection of the population and military personnel from the early transient incapacitation with simultaneous relief of the primary reaction to radiation. In terms of doing worrisomely such funds in the form of a pill, because these conditions dramatically reduced critical opportunities and possible panic that could lead to uncontrollable consequences.

The problem is solved by creating a combo drug consisting of 1,2,3,9-tetrahydro-9-methyl-3-[(2-methyl-1H-imidazol-1-yl)methyl]-4H-carbazole-4-it, or its hydrate, or its salts (1) and benzamide derivative (II) is selected from the group ArCONH2where aryl represents unsubstituted phenyl or phenyl substituted at the 3 rd position amino - or allmineral, and excipients necessary for obtaining a tablet dosage form.

Most preferred is the use of 1,2,3,9-tetrahydro-9-mepl-3-[(2-methyl-1H-imidazol-1-yl)methyl]-4H-carbazole-4-it is in the form of the hydrochloride dihydrate (ondansetron, latrine).

As a benzamide derivative can be used benzamide, 3-aminobenzamide or acyl derivatives of 3-aminobenzamide, for example, 3-(Butylimino)benzamide.

According to the invention offers the drug composition I:II=1:20-500 (weight ratio), preferably of the composition I:I=1:50-250.

Since the action of irradiation or large concentrations of cm increased levels of poly (ADP-ribose), the use of inhibitors of ADP-ribosylate, in particular, the benzamide derivatives of the General formula II, is an extremely useful from the point of view of protection from these damaging factors. These qualities can be particularly useful in clinical practice in the treatment of hematological and oncological diseases. Given that the benzamide derivatives possess significant antiviral activity (EP No. 0531370, class a 61 K 31/00), the proposed remedy will be especially useful when rentgenoterapii and chemotherapy of cancer patients, when humoral immunity is significantly reduced.

It is most convenient to solve the problem to use in order to themselves and others, tableted dosage form, in which in addition to the active ingredients should enter the required pharmaceutical additives and components. The required dosage form obtained by studying the compatibility of excipients with the active principles and to each other.

Tablets may be made by conventional means using one or more auxiliary components. Tablets can be made using the appropriate e powder or granules, possibly mixed with a binder component, a sliding additives, inert diluent, surface-active agent or dispersing agent. Molded tablets may be coated by a shell consisting of a sugar or a special film.

It is most convenient to use a tablet dosage form coated with a gastric-soluble coating. The required dosage form obtained by studying the compatibility of excipients with activetestsuite beginnings and among themselves.

As auxiliary substances used calcium carbonate, kaolin, gelatin, starch, magnesium carbonate, microcrystalline cellulose, milk sugar, Aerosil and other Use as excipients microcrystalline cellulose, Aerosil and starch; the mixture of Aerosil, starch and magnesium stearate as moving and an aqueous solution of starch as a binder gave the opportunity to obtain core tablets needed to cover properties in strength. Based on hydroxypropylcellulose developed coating tablets and matched the conditions of its application.

Example

The composition of core tablet, g:

Ondansetron of gyosil 0,010

Starch 0,018

The stearate 0,002

After coating the tablets obtained tablets are raspadaemost (102) min and release active substances to (962)%. The shelf life of the tablets is not less than 2 years.
