Description: Use of 3.4-diphenyl chromans for the manufacture of a pharmaceutical composition for the treatment or prophylaxis of hvperlipoproteinaemia, hypertriglyceridaemia, hyperlipidaemia or hypercholesterolaemia or arteriosclerosis or for anticoaαulative treatment FIELD OF THIS INVENTION The present invention relates to the use of compounds of the general formula I for the treatment of patients suffering from hyperlipoproteinae- mia, hypertriglyceridaemia, hyperlipidaemia or hypercholesterolaemia and prophylaxis hereof. The present invention furthermore relates to the use of compounds of the general formula I for the treatment of patients suffering from arteriosclerosis including atherosclerosis and prophylaxis hereof, and furthermore to the use of compounds of the general formula I for the treatment of patients in a need of an anticoagulative treatment or prophylaxis, e.g. following a coronary thrombosis or postoperatively i.e. after surgery. The present invention also embraces pharmaceutical compositions comprising these compounds and methods of using the compounds and their pharmaceutical compositions. BACKGROUND OF THIS INVENTION Ischemic heart disease (IHD) the relevant cardiovascular disease in relation to postmenopausal women, primarily is caused by atherosclerosis (Havel and Rapaport, N Eng J ed 1995; 332: 1491 - 1498). Other frequent manifestations of atherosclerosis is cerebrovascular disease, and intermittent claudication. An important risk factor for the development of atherosclerosis is an atherogenic lipid profile, i.e. hyperlipidaemia with increased LDL-cholesterol and relatively decreased HDL-cholesterol. In epidemiological studies (Samsioe G. Int J Fertil, 1993;38,suppl. 1 : 19-23) it has been indicated that estrogen therapy in postmenopausal women reduces the stenosis of the coronary arteries, thereby increasing survival rate compared to a non-treated population. An important factor in this effect on the coronary system is a reduction in serum lipids and a normalisation of the relation between LDL-cholesterol and HDL-cholesterol (Samsioe G. Int J Fertil 1994; 39 suppl. 1 :43-49). One object of the present invention is to provide compounds which can effectively be used in the treatment or prophylaxis of hyperlipoproteinae- mia, hypertriglyceridaemia, hyperlipidaemia or hypercholesterolaemia. Data on men suggest that a 35% reduction in LDL-cholesterol is required to achieve a 50% reduction in cardiovascular disease, i.e. coronary atherosclerosis provided that LDL-cholesterol reduction are the sole cause of cardioprotection. However, estrogens reduce LDL-cholesterols by only 5-10%. It is therefore now believed that the lipid effects account for only 25-40% of the reduction in the incidence of coronary heart disease after estrogen replacement therapy. A possible mechanism could be a direct effect on the vessel wall improving blood flow and inhibiting the atherogenic mechanisms independent on an effect on plasma lipids. Another object of the present invention is to provide compounds which can effectively be used in the treatment or prophylaxis of arteriosclerosis including atherosclerosis. Coagulation and thrombosis are important mechanisms involved in the pathogenesis of atherosclerosis and its complications such as vascular occlusion and embolism. Furthermore, blood clotting is important for the development of vascular restenosis following surgical intervention of blocked arteries. Restenosis occurs in about 35% of the patients after 6 months. Current therapy such as heparin , low molecular heparin and aspirin or stents have failed to reduce the incidence of restenosis. New therapeutic possibilities which can inhibit a tendency for thrombosis after endothelial damage are therefore needed. Another further object of the present invention is to provide compounds which can effectively be used in the treatment or prophylaxis of patients in a need of an anticoagulative treatment or prophylaxis, e.g. following a coronary thrombosis or after surgery. Recent studies (Writing group for the PEPI trial, JAMA 273:199, 1995) confirm that oral estrogen taken alone or in combination with medroxy- progesterone acetate or micronized progesterone is associated with a beneficial effect on the risk of developing cardiovascular disease through an improved effect on lipoprotein and the fibrinogen profile. However, estrogen is also known to have adverse effects on endometrium and perhaps breast tissue by increasing the frequency of malignancies in these areas after prolonged treatment. Thus, there is a need for new compounds which have beneficial effects on hyperlipoproteinaemia, hypertriglyceridaemia, hyperlipidaemia or hypercholesterolaemia or arteriosclerosis including atherosclerosis or as an anticoagulant, but without introducing significant effects in the reproductive tissues. Centchroman is a non-steroidal compound known to have antiestrogenic activity. It is in use in India as an oral contraceptive (see, for example, Salman et al., U.S. Patent Specification No. 4,447,622; Singh et al., Acta Endocrinal (Cooenh) 126 (1992). 444 - 450: Grubb, Curr Ooin Obstet Gvnecol 3 (1991 ), 491 - 495; Sankaran et al., Contrace p tion 9 (1974), 279 - 289; Indian Patent Specification No. 129187). Centchro- man has also been investigated as an anti-cancer agent for treatment of advanced breast cancer (Misra et al., Int J Cancer 43 (1989), 781 - 783). Recently, centchroman as a racemate has been found potent as a cholesterol lowering pharmaceutical expressed by a significant decrease of the serum concentrations (S.D. Bain et al., J Min Bon Res 9 (1994), S 394). U.S. patent 5,280,040 describes methods and pharmaceutical composi¬ tions for reducing bone loss using 3,4-diarylchromans and their pharma- ceutically acceptable salts. BRIEF DESCRIPTION OF THIS INVENTION It has, surprisingly, been found that compounds of the general formula I as stated in claim 1 can be used in the treatment or prophylaxis of hyperlipoproteinaemia, hypertriglyceridaemia, hyperlipidaemia or hyper¬ cholesterolaemia and furthermore it has also, surprisingly, been found that compounds of the general formula I as stated in Claim 2 and 3 can be used in the treatment or prophylaxis of arteriosclerosis including atherosclerosis and that compounds of the general formula I as stated in claim 4 can be used in the treatment or prophylaxis of patients in a need of an anticoagulative treatment or prophylaxis, e.g. following a coronary thrombosis or after surgery. DETAILED DESCRIPTION OF THIS INVENTION The present invention is based in part on the discovery that a representa¬ tive 3,4-diarylchroman, centchroman (3,4-trans-2,2-dimethyl-3-phenyl-4- [p-(beta-pyrrolidinoethoxy)phenyl]-7-methoxychroman) is effective as a hypolipoproteinaemic, hypotriglyceridaemic, hypolipidaemic or hypocho- lesterolaemic compound, inter alia in rabbits fed with cholesterol contain¬ ing diet. These animal models are generally recognized models of hyperli- poproteinaemia, hypertriglyceridaemia, hyperlipidaemia or hypercholeste¬ rolaemia. These data thus indicate that the 3,4-diarylchromans are useful as therapeutive and preventive hypolipoproteinaemic, hypotriglyceri- daemic, hypolipidaemic or hypocholesterolaemic agents in mammals, including primates such as humans. Furthermore, the present invention is based in part on the discovery that a representative 3,4-diarylchroman, centchroman (3,4-trans-2,2- dimethyl-3-phenyl-4-[p-(beta-pyrrolidinoethoxy)phenyl]-7-methoxychro- man) is also effective against the direct vascular effects of arteriosclero¬ sis including atherosclerosis, inter alia in rabbits fed with cholesterol containing diet. These animal models are generally recognized models of arteriosclerosis including atherosclerosis. These data thus indicate that the 3,4-diarylchromans are useful as therapeutic agents against arterio- sclerosis including atherosclerosis in mammals, including primates such as humans. The present invention is yet further based in part on the discovery that a representative 3,4-diarylchroman, centchroman (3,4-trans-2,2-dimethyl- 3-phenyl-4-[4-(2-(pyrrolidin-1 -yl)ethoxy)phenyl]-7-methoxychroman) has preventive or therapeutic anticoagulative activities when administered inter alia to rats. These animal models are generally recognized models of patients in a need of an anticoagulative treatment or prophylaxis, e.g. following a coronary thrombosis or after surgery. These data thus indicate that the 3,4-diarylchromans of formula I are useful as thera¬ peutic and preventive agents to mammals, including primates such as humans, in a need of an anticoagulative treatment or prophylaxis, e.g. following a coronary thrombosis or after surgery. This invention is related to the treatment or prophylaxis of disorders as defined in the Lipid Research Clinics Program. J.A.M.A. 251 (1984), 351-364 and J.A.M.A. 251 (1984), 365 - 374 or what a person skilled in the art may consider as subject for treatment or prophylaxis. Within the present invention, compounds of formula I are used for the indications as stated in claims 1 -4 in a patient. Within formula I, R1 , R4 and R5 are individually hydrogen, halogen, trifluoromethyl, lower alkyl, lower alkoxy or (tertiary aminoMlower alkoxy); and R2 and R3 are indivi¬ dually hydrogen or a lower alkyl. As used herein, the term "lower alkyl" includes straight and branched chain alkyl radicals containing from 1 to 6 carbon atoms, such as methyl, ethyl, n-propyl, isopropyl, n-butyl, tert- butyl, n-amyl, sec-amyl, n-hexyl, 2-ethylbutyl, 2,3-dimethylbutyl and the like. The term "lower alkoxy" includes straight and branched chain alkoxy radicals containing from 1 to 6 carbon atoms, such as methoxy, ethoxy, n-propoxy, isopropoxy, n-butoxy, tert-butoxy, n-amyloxy, sec- amyloxy, n-hexyloxy, 2-ethylbutoxy, 2,3-dimethylbutoxy and the like. "Halogen" includes chloro, fluoro, bromo and iodo. The tertiary amino radical may be a N,N-dialkylamine such as a N,N-dimethylamino, N,N- diethylamino, N,N-dipropylamino and N,N-dibutylamino or a polymethy- leneimine, e.g., piperidine, pyrrolidine, N-methylpiperazine or morpholine. Herein, the term "(tertiary aminoMlower alkoxy)" is a lower alkoxy group which is substituted by a tertiary amino group. Preferred compounds include those in which R ' is lower alkoxy; R^ and R^ are lower alkyl, especially methyl; R^ is hydrogen; and R^ is (tertiary aminoMlower alkoxy) of the polymethyleneimine type. Within particularly preferred embodiments, R is in the 7-position and is lower alkoxy, particularly methoxy; each of R^ and R^ is methyl, R 4 is hydrogen, and R 5 is in the 4-position and is a (tertiary aminoMlower alkoxy) radical such as 2- (pyrrolidin-l -yl)ethoxy. To be included by this invention are all pharma¬ ceutically acceptable salts of the mentioned compounds of formula I. It is preferred to use the compounds of formula I in the transconfigura- tion. These compounds may be used as racemic mixtures, or the isolated stereoisomers e.g. d- or I- enantiomers, may be used. The trans-l-en- antiomers are more preferred. A particularly preferred compound for use within the present invention is centchroman having the formula IV as stated in claim 14. Although only one enantiomer is shown, it will be understood that the formula IV is used herein to designate the transconfiguration of the 3- and 4-phenyl groups and that both the d- and l-enantiomers, as well as the racemic mixture are included. 3,4-diarylchromans are prepared according to known methods, such as those disclosed in U.S. Patent Specification No. 3,340,276 to Carney et al., U.S. Patent Specification No. 3,822,287 to Bolger, and Ray et al., J Med Chem 19 (1976), 276 - 279, the contents of which are incorpo- rated herein by reference. Conversion of the cis isomer to the trans configuration by means of an organometallic base-catalyzed rearrange¬ ment is disclosed in U.S. Patent Specification No. 3,822,287. The optically active d- and l-enantiomers may be prepared as disclosed by Salman et al. in U.S. Patent Specification No. 4,447,622 (incorporated herein by reference) by forming an optically active acid salt which is subjected to alkaline hydrolysis to produce the desired enantiomer. If R 2 is different from R 3 and R 4 is different from R 5 , the general formula I covers 8 optical isomers. Within the present invention, 3,4-diarylchromans may be prepared in the form of pharmaceutically acceptable salts, especially acid-addition salts, including salts of organic acids and mineral acids. Examples of such salts include salts of organic acids such as formic acid, acetic acid, propionic acid, fumaric acid, glycolic acid, lactic acid, pyruvic acid, oxalic acid, succinic acid, malic acid, tartaric acid, citric acid, benzoic acid, salicylic acid and the like. Suitable inorganic acid-addition salts include salts of hydrochloric, hydrobromic, sulphuric and phosphoric acids and the like. The acid addition salts may be obtained as the direct products of com¬ pound synthesis. In the alternative, the free base may be dissolved in a suitable solvent containing the appropriate acid, and the salt isolated by evaporating the solvent or otherwise separating the salt and solvent. 3,4-diarγlchromans and their salts are useful within human and veteri¬ nary medicine, for example, in the treatment or prevention of patients suffering from hyperlipoproteinaemia, hypertriglyceridaemia, hyperlipidaemia or hypercholesterolaemia or arteriosclerosis including atherosclerosis or in need of anticoagulative treatment or prophylaxis e.g. following a coronary thrombosis or after surgery. For use within the present invention, 3,4-diarylchromans and their pharmaceutically accept¬ able salts are formulated with a pharmaceutically acceptable carrier to provide a medicament for parenteral, oral, nasal, rectal, subdermal or intradermal or transdermal administration according to conventional methods. Formulations may further include one or more diluents, fillers, emulsifiers, preservatives, buffers, excipients, etc. and may be provided in such forms as liquids, powders, emulsions, suppositories, liposomes, transdermal patches, controlled release, dermal implants, tablets, etc. One skilled in this art may formulate the compounds in an appropriate manner, and in accordance with accepted practices, such as those disclosed in Remington's Pharmaceutical Sciences. Gennaro, ed., Mack Publishing Co., Easton, PA, 1990. Oral administration is preferred. Thus, the active compound is prepared in a form suitable for oral administration, such as a tablet or capsule. Typically, a pharmaceutically acceptable salt of the compound is com¬ bined with a carrier and moulded into a tablet. Suitable carriers in this regard include starch, sugars, dicalcium phosphate, calcium stearate, magnesium stearate and the like. Such compositions may further include one or more auxiliary substances, such as wetting agents, emulsifiers, preservatives, stabilizers, colouring additives, etc. Pharmaceutical compositions containing a compound of formula I may be administered one or more times per day or week. An effective amount of such a pharmaceutical composition is the amount that provides a clinical¬ ly significant effect as hypolipoproteinaemic, hypotriglyceridaemic, hypolipidaemic or hypocholesterolaemic agents or a clinically significant effect against arteriosclerosis including atherosclerosis or provides a clinically significant effect to patients in a need of an anticoagulative treatment or prophylaxis e.g. following a coronary thrombosis or after surgery. Such amounts will depend, in part, on the particular condition to be treated, age, weight, and general health of the patient, and other factors evident to those skilled in the art. The pharmaceutical compositions containing a compound of formula I may be administered in unit dosage form one or more times per day or week. In the alternative, they may be provided as controlled release formulations suitable for dermal implantation. Implants are formulated to provide release of active compound over the desired period of time, which can be up to several years. Controlled-release formulations are disclosed by, for example, Sanders et al., J Pharm Sci 73 (1964), 1294 - 1297, 1984; U.S. Patent Specification No. 4,489,056; and U.S. Patent Specification No. 4,210,644, which are incorporated herein by refe¬ rence. The following examples are offered by way of illustration, not limitation. Examples of preferred compounds of formula I are centchroman as a racemic mixture and as l-centchroman and d-centchroman. Furthermore, 3,4-trans-2,2-dimethyl-3-phenyl-4-[4-(2-(pyrrolidin-1 -yl)ethoxy)phenyl]-7- hydroxychroman is a preferred compound. The more preferred compound is trans-l-centchroman (l-3,4-trans-2,2-dimethyl-3-phenyl-4-[4-(2-(pyrro- lidin-1 -yl)ethoxy)phenyl)-7-methoxychroman). Examples of pharmaceutically acceptable acid addition salts are salts with non-toxic acids, either inorganic acids such as hydrochloric acid, sulphuric acid and phosphoric acid, or organic acids such as formic acid, acetic acid, propionic acid, succinic acid, fumaric acid, glyconic acid, lactic acid, citric acid, ascorbic acid, benzoic acid, embonic acid, metha- nesulphonic acid and malonic acid. The present invention is further illustrated by the following examples which, however, are not to be construed as limiting the scope of protec- tion. The features disclosed in the foregoing description and in the following examples may, both separately and in any combination thereof, be material for realising the invention in diverse forms thereof. EXAMPLE 1 The effects of l-centchroman on plasma cholesterol have been invest! gated in both rats and rabbits. In the first study sham surgery or ovariectomy (OVX) was performed on 56 female Sprague-Dawley rats and the animals were assigned to the following treatments (8 rats per group) : 1 ) sham/vehicle; 2) OVX/vehicle, 3) OVX/ethynyl estradiol 0.2 mg/kg; 4) OVX/l-centchroman 1 mg/kg; 5) OVX/l-centchroman 5 mg/kg; 6) OVX/l-centchroman 10 mg/kg;7) OVX/l-centchroman 25 mg/kg. The doses were administered three times per week for 5 weeks by oral gavage. At the conclusion of the experi¬ ment serum was collected for determination of cholesterol level (US patent 5,407,955). l-centchroman had a marked effect on serum cholesterol in all doses and reduced the cholesterol level even below the level of the sham operated animals (Table 1 ) . Table 1 .

In order to show a clear dose-response effect on serum cholesterol a further study was performed with l-centchroman. Again sham surgery or ovariectomy was performed on 56 female rats and the rats were assigned to the following treatments: 1 ) sham/vehicle; 2) OVX/vehicle, 3) OVX/ethynyl estradiol 0.2 mg/kg; 4) OVX/l-centchro¬ man 0.05 mg/kg; 5) OVX/l-centchroman 0.1 mg/kg; 6) OVX/l-centchro¬ man 0.5mg/kg;7) OVX/l-centchroman 1 mg/kg. The doses were admini¬ stered three times per week for 5 weeks by oral gavage. At the con¬ clusion of the experiment serum was collected for determination of cholesterol level (US patent 5,407,955). In this experiment serum cholesterol was reduced in a dose-dependent manner (table 2). Table 2.

The effects of l-centchroman on plasma lipids were also investigated in cholesterol fed rabbits. One week before the experiment was started 30 sexually mature New Zealand White rabbits were ovariectomized during pentobarbital anaesthesia. Following recovery subcutaneous treatment was started in three groups: Vehicle, 17-β-estradiol or l-centchroman 7.5 mg/kg. The doses were administered three times per week for 4 weeks. At the end of the experiment plasma samples for analysis of serum cholesterol were taken. As shown in table 3 l-centchroman reduced serum cholesterol significantly compared to the level in vehicle treated animals and estrogen treated animals. Table 3.

EXAMPLE 2 The effects of l-centchroman on the acummulation of lipid into the aortic wall i.e. a central mechanism in the atherogenic process was investi¬ gated in New Zealand White rabbits. One week before the experiment was started 45 sexually mature New Zealand White female rabbits were ovariectomized during pentobarbital anaesthesia. Additionally a group of 45 age and weight matched male rabbits were included in the experi¬ ment. Following recovery oral treatment was commenced. Males and females were treated in 3 groups (15 animals per group): 1 ) Placebo treated animals; 2) 17-β-estradiol 2.5 mg/kg /day; 2) l-centchroman, 2.5 mg/kg/day. After 14 days of treatment cholesterol was added to the food. Every second day a blood sample was collected from each rabbit and the total serum cholesterol was determined. (Holm P et al. Atherosclerosis 1 15:191 , 1995). On basis of this measurement the cholesterol concentration in the feeding was regulated on the following days until next measurement. In that way serum cholesterol was kept constant throughout the treatment period even though some of the treatments are known to have effects on plasma cholesterol level. The direct effect of treatment on the vessel wall could then be isolated. After 3 months of treatment the animals were killed, the aorta from each animal was isolated and the cholesterol accumulated within the intima of the aorta was determined. (Holm P et al Atherosclerosis, 1 15:191 , 1995). The results are shown in table 4. It is clearly seen that both estrogen and l-centchroman in both male and female rabbits had a significant reducing effect on the iπtimal cholesterol content, which is independent of the serum cholesterol since this was kept constant throughout the experiment. The anti-atherosclerotic effect of l-centchroman may there¬ fore partly be due to a direct vascular wall effect. Table 4.

EXAMPLE 3 In vitro it has been shown that l-centchroman in rabbit platelet-rich plasma inhibited platelet aggregation induced by platelet activating factor (PAF). EC50 for this effect was between 3 and 10 g/ml. ADP- induced aggregation was not affected.
