     The compounds according to the invention are valuable neurokinin (tachykinin) antagonists which have both substance P antagonism and also neurokinin A and neurokinin B antagonistic properties. They are useful for the treatment and prevention of neurokinin-mediated diseases: 
     for the treatment or prevention of inflammatory and allergic diseases of the respiratory tract, such as asthma, chronic bronchitis, hyperreactive respiratory tract, emphysema, rhinitis and cough, 
     and of the eyes, such as conjunctivitis and iritis, 
     of the skin, such as dermatitis in contact eczema, urticaria, psoriasis, sunburn, insect bites and stings, itching, sensitive or hypersensitive skin, 
     of the gastrointestinal tract, such as gastric and duodenal ulcers, ulcerative colitis, Crohn&#39;s disease, irritable bowel and Hirschsprung&#39;s disease, 
     of the joints, such as rheumatoid arthritis, reactive arthritis and Reiter syndrome; 
     for treating diseases of the central nervous system such as dementia, Alzheimer&#39;s disease, schizophrenia, psychoses, depression, headache (e.g. migraine or tension headaches), epilepsy, Parkinson&#39;s disease and stroke; 
     for treating herpes zoster and postherpetic pain, tumours, collagenoses, dysfunction of the deferent urinary tract, haemorrhoids, nausea and vomiting, caused for example by radiation or cytostatic therapy or motion and pain of all kinds. 
     The invention therefore also relates to the use of the compounds according to the invention as therapeutic agents and pharmaceutical preparations which contain these compounds. They are preferably used in humans. The compounds according to the invention may be administered by intravenous, subcutaneous, intramuscular, intraperitoneal or intranasal route, by inhalation, by transdermal route, optionally aided by iontophoresis or enhancers known from the literature, and by oral route. 
     For parenteral administration the compounds of formula I or the physiologically acceptable salts thereof, possibly with the conventional substances such as solubilisers, emulsifiers or other adjuvants, are dissolved, suspended or emulsified. Solvents which may be used include: water, physiological saline solutions or alcohols, e.g. ethanol, propanediol or glycerol, sugar solutions such as glucose or mannitol solutions or a mixture of several solvents. 
     In addition, the compounds may be administered by means of implants, e.g. of polylactide, polyglycolide or polyhydroxybutyric acid or intranasal preparations. 
     The oral efficacy of compounds of general formula I can be demonstrated by the following standard test: 
     Inhibition of lowering of blood pressure caused by NK 1  in anaesthetised guinea pigs. 
     Guinea pigs weighing 300-500 grams were anaesthetised with pentobarbital (50 mg/kg i.p.), intubated and artificially ventilated. They were ventilated with 10 ml/kg of air at a frequency of 60 breaths per minute. The carotid artery was canulated and the arterial blood pressure was recorded. A polyethylene tube was inserted into the jugular vein for the intravenous supply of substances. 
     A temporary reduction in blood pressure was brought about at intervals of 10 minutes by intravenous administration of the NK 1 -agonist [(βAla 4 , Sar 9 , Met (O 2 ) 11 ]SP (4-11)                           
     in a dose of 0.2 μmol/kg. After the blood pressure thus produced has been measured, the test compound was introduced into the duodenum and the NK 1 -agonist was again injected every 10 minutes. 
     The results were expressed as a % inhibition of the reduction in blood pressure caused by the NK 1 -agonist specified. 
     In a dosage of 1 mg/kg (administered into the duodenum) the compound of Example 1 inhibited the lowering of blood pressure caused by the NK 1 -agonist by 80%. 
     The compounds according to the invention can be produced using generally known methods. 
     The compounds may be prepared in various ways. The two most common procedures are represented by the following diagram:                           
     Method A. The carboxylic acid may be linked to the amine HN(R 5 )R 4  by various methods. Conventional methods are coupling processes such as those used in peptide chemistry. A coupling reagent such as TBTU, DCCI/HOBt, CDI, etc., is added to the coupling partners in substantially equivalent quantities. Suitable solvents are DMF, THF, CH 2 Cl 2 , CHCl 3 , acetonitrile or other inert solvents or mixtures thereof. The suitable temperature range is between −50° C. and +120° C., preferably between 0° C. and 40° C. 
     The carboxylic acid may also initially be converted into the corresponding acid halide by known methods using SOCl 2 , SO 2 Cl 2 , PCl 3 , PCl 5  or PBr 3  or mixtures thereof, and the acid halide is then reacted with the amine HN(R 5 )R 4  in an inert solvent such as CH 2 Cl 2 , THF or dioxane at temperatures between −50° C. and +100° C., typically at 0° to 20° C. 
     Another alternative is to convert the carboxylic acid initially into the alkylester, usually the methylester, by known methods and this ester is then reacted with the amine HN(R 5 )R 4  in an inert solvent such as DMF, dioxane or THF. The reaction temperatures are between 20° C. and 150° C., typically between 50° C. and 120° C. The reaction may also be carried out in a pressurized container. 
     Method B. Here, the α-halo-arylacetamide derivative obtained by known methods is reacted with the amine R 1 (R 2 )NH, thereby cleaving hydrogen halide. Inorganic bases such as K 2 CO 3 , NaHCO 3  or CaCO 3  or organic bases such as triethylamine, Hünig base, pyridine or DMAP are used to mop up the cleaved (or excess) hydrogen halide, or an excess of the amine R 1  (R 2 )NH may be used. DMF, THF, dioxane or other inert solvents are used. The temperature range for the reaction is from 0 to 100° C., typically between 10 and 80° C. 
     Method C. The compounds according to the invention wherein R 5  is not H may also be prepared as follows: first of all, the corresponding compound in which R 5  is H is synthesised using method A or B. Then, N-alkylation is carried out as follows in order to introduce alkyl, cycloalkyl or CH 2 COOH. The compounds according to the invention wherein R 5  is H are deprotonated with an equivalent quantity of NaH, NaNH 2 , KOH, NaOCH 3  or another strong base. Anhydrous inert solvents such as THF, dioxane or diethylether are used for this. Then the corresponding alkylating agent is added slowly in the form of the corresponding halide, tosylate or mesylate. The reaction is carried out at a temperature within the range from −50° C. to +100° C., typically between 0° C. and +5° C. 
    
    
     EXAMPLE 1 
                              1st step: 0.71 g of 1-isopropylpiperazine were dissolved in 55 ml of anhydrous DMF, mixed with 0.64 g of Na 2 CO 3 , stirred for 20 minutes at RT and then cooled to 5° C. 1.15 g of methyl (R,S)-α-bromophenylacetate were added and the suspension was stirred overnight at RT. The precipitate was filtered off and the filtrate was evaporated down. The residue was taken up in ethyl acetate, extracted twice with 10% KHCO 3  solution and once with saturated NaCl solution. The organic phase was dried over Na 2 SO 4 , filtered and evaporated down, to yield 1.23 g of methyl (R,S)-1-isopropyl-4-(2-phenylacetate) piperazine as a viscous oil. 
     Yield: about 89%. 
     2nd step: 1.23 g of the product from the 1st step were dissolved in 10 ml of methanol and 10 ml of THF, mixed with 10 ml of 1N NaOH and the mixture was stirred overnight at ambient temperature. The clear reaction solution was neutralised by the addition of 10 ml of 1N HCl, evaporated to dryness, the residue was treated with DMF and the solid was separated by suction filtering. The filtrate was evaporated down and the residue was triturated with ether, the solid substance removed by suction filtering and dried in a desiccator. In this way, 1.1 g of (R,S)-1-i-propyl-4-(2-phenylacetic acid)-piperazine were obtained as a solid white substance. 
     Yield: 92%. 
     3rd step: 0.37 g of the product of the 2nd step and 0.42 g of N-methyl-3,5-bis-(trifluoromethyl)-phenylethylamine were dissolved in 14 ml of DMF and adjusted to pH 8.5 by the addition of about 0.4 ml of TEA. 0.48 g of TBTU were added and the mixture was stirred overnight at room temperature. The clear reaction solution was evaporated down in vacuo, the residue was stirred with NaHCO 3  solution and extracted twice with ethyl acetate. The combined organic phases were filtered and the filtrate was evaporated down. The residue was chromatographed over silica gel using CH 2 Cl 2 /MeOH (9:1) as eluant. The uniform fractions obtained were evaporated down, dissolved in a little MeOH, acidified with ethereal HCl and evaporated down again. The residue was triturated with ether and dried in a desiccator. 0.58 g of (R,S)-1-i-propyl-4-[2-phenylacetic acid-N-methyl-N-(3,5-bistrifluoromethyl-phenylethyl)]-amide dihydrochloride were obtained as a solid white substance. 
     Yield: 75%.
