DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pharmaceutical composition with high antispasmodic activity. In particular, the present invention relates to antispasmodic compositions for the treatment of humans or animals, which contain certain propionamide derivatives or pharmaceutically acceptable salts thereof as active ingredients. Among the known compounds that are commonly used therapeutically as antispasmodic agents, their action is often found to be limited to the gastrointestinal tract. These orally administered compounds exhibit antispasmodic effects on organs and systems other than the gastrointestinal tract, but exhibit side effects similar to atropine. The present inventors have now discovered that the racemic or optically active propionamide derivatives represented by the general formula () and their non-toxic pharmaceutically acceptable salts are:
It has been found that it is particularly suitable for use as an antispasmodic agent, either orally or parenterally. According to the invention, therefore, a non-toxic and inert carrier and a unit dose of 5 to 40 mg of the general formula (): (wherein n is 2 or 3 and Et represents C2H5- ) and at least one non-toxic salt thereof; be done. These compounds of general formula () and their salts have the following properties: (a) block the transmission of nerve impulses to muscle fibers (parasympathetic nerve inhibitory effect); (b) suppress contraction of smooth muscle tissue ( Direct muscle degeneration effect,
direct myolytic activity); and (c) fewer side effects on the central and peripheral nervous systems. The compound represented by the general formula () and its non-toxic salts are particularly suitable for oral and parenteral administration, and are known for their parasympathetic suppressive effects, myopathic effects and low side effects on the central and peripheral nervous systems. It was observed that the compound differed from known compounds in some respects. As mentioned above, the compound of general formula () has an antispasmodic effect, ie, a relaxing effect on smooth muscles such as those of the gastrointestinal tract (including the gallbladder), the urinary tract and the respiratory tract. Specific examples of compounds represented by formula () are as follows: (1) 2-(4-biphenylyl)-N-(2-diethylaminoethyl)propionamide; (2) 2-(4 -biphenylyl)-N-(3-diethylaminopropyl)propionamide; (3) d2-(4-biphenylyl)-N-(2-diethylaminoethylpropionamide; (4) l2-(4-biphenylyl)-N-( 2-diethylaminoethyl)propionamide; (5) d2-(4-biphenylyl)-N-(3-diethylaminopropyl)propionamide; (6) l2-(4-biphenylyl)-N-(3-diethylaminopropyl)propion Amides. Pharmaceutically acceptable salts of the above compounds include:
Mention may be made, for example, of the non-toxic chlorides, bromides, iodides, phosphates and sulphates as well as methyl bromide, methyl iodide, ethyl bromide and ethyl iodide. Compounds of formula () may be prepared by known methods. In particular, these compounds are prepared by combining racemic or optically active functional derivatives of 2-(4-biphenylyl)propionic acid with N·N-diethylethylenediamine or N·N-diethyl-1,3-propylenediamine in a suitable solvent. It is produced by reacting in the presence of Racemic or optically active 2-
As functional derivatives of (4-biphenylyl)propionic acid, the chlorides or the corresponding anhydrides of the above acids are very useful, as well as the esters of the above acids, especially the lower alkyl esters such as the methyl esters. Useful. N·N-diethylethylenediamine or N·N-diethyl-
Preferably, a condensation reaction with 1,3-propylene diamine is carried out. Compounds 3, 4, 5 and 6 are also prepared using known methods suitable for resolving the optical enantiomers of substances having the basic characteristics of a racemate containing one asymmetric carbon atom. , and can be prepared starting from dl2-(4-biphenylyl)-N-(diethylaminoalkyl)propionamide. Salts of compounds of formula () may also be prepared by known methods. Alkyl halogenated derivatives can be obtained by alkylating a base of formula () using an alkylating agent such as an alkyl chloride, alkyl iodide or an alkyl bromide in a suitable solvent such as dioxane, acetone, ethyl ether.

9, 381, (1957) by measuring the movement of charcoal meal in the intestines of mice stimulated with Bacl 2 . In addition, the potential parasympathetic suppressive effect of the propionamide derivative of the present invention was investigated in anesthetized guinea pigs by the following two methods, namely, by measuring the antagonistic effect on bronchoconstriction induced by carbachol ( Measurements were made by MERosenthale and A.Pervinis,
Arch, Int. Pharmacodyn 1 , 172, 1968); and by measuring brady cardia and hypotension (measurements were carried out according to JPLong and CTChiou, J.Pharm.
Science, 59 , 133, 1970). The results are shown in Table 1. [Table] These results clearly show that administration of the propionamide derivative of the present invention exhibits a good antispasmodic effect. In fact, the known 2-(4-biphenylyl)-N-(2-diethylaminoethyl)acetamide (G. Garallini, F. Ravenna, Farm. Sci.
Tecn. 3 648, 1948), whose direct parasympathetic inhibitory activity and muscle degenerative activity are racemic and d
-type 2-(4-biphenylyl)-N-(2-diethylaminoethyl)propionamide is clearly lower. Furthermore, the latter compound has an antagonistic effect on smooth muscle contraction (direct muscle degenerative effect) that is at least 1.5 times greater than dicyclomine, and an effect that inhibits the transmission of nerve impulses to muscle fibers (parasympathetic inhibitory effect). ) is 1 to 10 times larger than dicyclomine.

tremors and peripheral effects (salvation, lacrimation, diarrhea); also by J. Scheel-Kruger. Acta. Pharmacol. Toxicol . 28 , 1, (1970)
The atropine-like side effects of the propionamide derivatives of the present invention were investigated by conducting an apomorphine test to measure the central cholinergic inhibitory effect according to the method described in . The results are shown in Table 2. 【table】
compared.
Compound 2: 2-(4-biphenylyl)-N-(2-diethylaminoethyl)propionamide From the results shown in Table 2, it was compared with 2-(4-biphenylyl)-N-(2-diethylaminoethyl)propionamide. In this case, dicyclomine and scopolamine butyl bromide are found to have 5 to 6 times greater central and peripheral nerve side effects. Regarding central cholinergic depressant action, dicyclomine and atropine sulfate exhibit approximately twice as many side effects as 2-(4-biphenylyl)-N-(2-diethylaminoethyl)propionamide.

None of the test compounds exhibited antiphlogistic properties. Toxicity Test Acute toxicity ( LD50 ) was investigated by orally administering the compound of the present invention to mice. The results are shown in Table 3. [Table] The present invention further provides a pharmaceutical composition comprising at least one compound of the general formula () and a pharmaceutical carrier or excipient. The pharmaceutical composition may be provided in a suitable form containing 5 to 40 mg of active ingredient, such as for oral or parenteral or enteral administration. Suitable dosage forms may include vials, tablets, coated tablets, capsules, sweetened tablets, dispersible powders, syrups, elixirs and suppositories. Preferably, the pharmaceutical composition is in a single dosage form.
