- the two parts of the chamber are sewn after having carefully removed the skin thicknesses which may hinder observation.
- a jugular catheter is placed for IV administration of the products, 48 hours after the operation.
- the vascular permeability is studied m vi vo by measuring the extravasation of albumin whose quantity e is determined using an albumin binding dye (Evans Blue). Hyperpermeability is induced by in ⁇ tradermal injection of a histamme, bradykmine or zymosan solution. The technique is derived from that described by BEACH

- the optical densities are quantified by absorption spectrophotometry at a wavelength of 620 nm, against a blank containing only dichloromethane.
- the averages of the optical densities of the different batches of treated or control animals are calculated, then a percentage change in the values corresponding to the treated animals compared to those of the control animals is calculated.
- the effect of the compounds on the hyperpermeability induced by inflammatory agents, such as histamma and bra ⁇ ykinme is also studied after injection.
- the increase in the capillary resistance is ap ⁇ voltageciée by the modification of the petechial index (negative pres ⁇ sion inducing the extravasation of erythrocyte your) measured by a method derived from the angiosterro- meter of Parrot.
- the study is carried out on male Wistar rats weighing an average of 200 g (around six weeks old). The region of the lower back is shaved and then depilated using a paste based on an ⁇ é ⁇ ve of thioglycolic acid and calcium hydroxide. After about thirty minutes, the skin is thoroughly rinsed and dried.
- the rats were kept unconstrained. A vacuum of 80 mm of mercury is applied. If the petechies (extravasation of erythrocytes) have not appeared within 15 seconds, the depression is increased by compensating by keeping the suction cup in the same place.
- the minimum depression for which the petechies appear expresses, in mm of mercury, the value of basic capillary resistance (before any treatment). Two measurements are made for each test at different locations on the back.
- the rats are treated orally. After a determined time (generally 2, 4, 6 hours) depending on the treatment, the test is repeated on different areas of skin, until the appearance of petechiae, providing a new index of depression. All measurements are made blind. A percentage change in the capillary resistance of the treated animals with respect to their basic capillary resistance is calculated for each study compound, at each treatment time and compared with the control group (excipient only) or the reference group. Effects on induced pleurisy in rats:
- the anti-inflammatory activity of the compounds is also studied by measuring the inhibition of edema and leukocyte migration after induction of rain in the rat by injection of carrageenan into the pleural cavity (ALMEIDA et al ., J. Pharmacol. Exp. Rap., 1980, 214: 74).
- the rats are treated per os with the compounds 2 hours before the injection of carrageenan, as well as 2 and 4 hours after this injection. After a determined time (6 hours) following the induction of pleurisy, the rats are euthanized and the pleural fluid recovered by aspiration and its volume is measured. The leukocyte cells are counted by "cell counter”.
- the results are expressed in number of leukocytes in the exudate relative to 100 g of animal weight and compared to those of the control batch.
- the compounds of the invention and their possible salts selectively increase in the majority of cases the contraction of the animal veins produced by the noradrenal, by electrical stimulation or by a depolarizing hyperpotassic solution.

- Example b 0.1 mg / kg -5 -23
- Example 4 0.1 mg / kg 3 -37
- Example 10 0.1 mg / kg -7 -14
- Example 15 0.1 mg / kg -14 -17
- the compounds of the invention and their possible salts are very little toxic. For example, after a single oral administration of 500 mg / kg in the penny ⁇ laugh, no ooservable toxicity and no mortality was observed for the majority of compounds espe- link for Example c, Example d, Example 2, Example 3 (orange urine), Example 5.
- the compounds of the invention and their possible salts can be used in human and animal therapy. They are particularly indicated in functional, organic venous insufficiency and hemorrhoidal pathologies by their vascular and anti-inflammatory components, as well as in typically inflammatory conditions and in shock states constituted by a significant drop in blood pressure. . In the latter case, an improvement in venous return is likely to maintain the cardiac output and consequently blood pressure.
- Functional venous insufficiency is characterized by dilation and hyperdistensitivity of the superficial veins of the lower limbs, edemas, impatience type paresthesias, restless leg.

L'étude des composes de la présente invention et de leurs sels éventuels a démontre qu'ils possèdent diverses propriétés pharmacologiques. Ainsi, ils sont sélective¬ ment vemotoniques, n'affectant le système artériel qu'a des concentrations largement supérieures a celles actives sur les veines, excepte certaines artères, en particulier cérébrales. Les composes ne montrent aucune affinité soit une très faible affinité pour les récepteurs pharmacolo¬ giques membranaires connus. Par ailleurs, ils augmentent la résistance capillaire, diminuent l' hyperpermeabilite
vasculaire induite par certains agents inflammatoires.The study of the compounds of the present invention and their possible salts has demonstrated that they have various pharmacological properties. Thus, they are selectively vemotonic, affecting the arterial system only at concentrations much higher than those active on the veins, except certain arteries, in particular cerebral. The compounds show no affinity, ie a very weak affinity for the known membrane pharmacological receptors. Furthermore, they increase capillary resistance, decrease hyperpermeability vascular induced by certain inflammatory agents.
Ces propriétés sont mises en évidence chez les mam¬ mifères tels que les hamsters, rats, cobayes et lapins, dans des conditions in vitro (vaisseaux ou reseaux vascu- laires isoles) et m vivo.These properties are demonstrated in mammals such as hamsters, rats, guinea pigs and rabbits, under in vitro conditions (isolated vessels or vascular networks) and in vivo.
Pour les études m vitro, les composés sont solubi¬ lises en solution aqueuse pure ou contenant du DMSO (dimethylsulfoxyde) .For in vitro studies, the compounds are solubi¬ lized in pure aqueous solution or containing DMSO (dimethylsulfoxide).
Pour les études m vivo, ils sont administres par voie intraveineuse ou mtrapeπtoneale sous forme de so¬ lution aqueuse contenant ou non du DMSO, ou par voie orale en suspension dans la carboxymethylcellulose a 1°, administres a l'aide d'une sonde de gavage sous un volume de 10 ml/kg. Modèles d' études pharmacologiques Effets contractilesFor m vivo studies, they are administered intravenously or mtrapeπtoneale in the form of an aqueous solution containing or not DMSO, or orally suspended in carboxymethylcellulose at 1 °, administered using a probe of force-feeding in a volume of 10 ml / kg.

The rings are placed in an isolated organ chamber
(25 ml pour les vaisseaux a capacitance et 2,5 ml pour les vaisseaux a résistance selon Mulvany) , maintenus dans des conditions isométriques par deux fils rigides insères a l' intérieur du vaisseau, en évitant d'endommager l' endothelium. Les vaisseaux sont baignes par une solu¬ tion de Krebs modifiée (en mM: NaCl = 118 ; KC1 = 4,6 ; CaCl2 = 2,5; MgS04 = 1,2 ; KH2P04 = 1,17 ; NaHC03 = 25 ; glucose = II), aeree en permanence par un mélange gazeux a 95 ", 02 et 5 -> C02, a pH = 7,4 et thermostates a 37°C. Les anneaux sont amenés a leur point optimal de la rela-
tion tension-longueur.(25 ml for capacitance vessels and 2.5 ml for resistance vessels according to Mulvany), maintained under isometric conditions by two rigid wires inserted inside the vessel, avoiding damage to the endothelium. The vessels are bathed with a modified Krebs solution (in mM: NaCl = 118; KC1 = 4.6; CaCl 2 = 2.5; MgS0 4 = 1.2; KH 2 P0 4 = 1.17; NaHC03 = 25; glucose = II), permanently aerated by a gas mixture at 95 ", 0 2 and 5 -> C0 2 , at pH = 7.4 and thermostats at 37 ° C. The rings are brought to their optimal point of the rela- tension-length.
Les tensions développées génèrent un signal électri¬ que par l'intermédiaire d'un capteur de force (pont de Wheastone) . Ce signal est amplifié avant d'être soit vi- sualise sur enregistreur Kipp & Zonen, soit digitalisé pour être traité par ordinateur (IOS, EMKA) . Les études pharmacologiques sont réalisées après quelques stimula¬ tions contractiles préliminaires standardisées par une solution dépolarisante (hyperpotassique obtenue en rem- plaçant du NaCl par du KC1 en quantités équimolaires) , rinçages et périodes d'équilibration en solution physio¬ logique pure. La présence d' endothelium est vérifiée par la relaxation induite par des concentrations croissantes d' acetylcholme après stabilisation d'une précontraction vasculaire.The developed voltages generate an electrical signal only via a force sensor (Wheastone bridge). This signal is amplified before being either displayed on a Kipp & Zonen recorder, or digitized for processing by computer (IOS, EMKA). Pharmacological studies are carried out after a few preliminary contractile stimulations standardized by a depolarizing solution (hyperpotassic obtained by replacing NaCl with KC1 in equimolar quantities), rinses and equilibration periods in pure physiological solution. The presence of endothelium is verified by the relaxation induced by increasing concentrations of acetylcholme after stabilization of a vascular pre-contraction.
Les forces de contraction développées par les an¬ neaux vasculaires en réponse aux différents composés sont étudiées sur des vaisseaux quiescents ou stimules élec¬ triquement (5-8 Hz), par une solution "physiologique" dé- polarisante hyperpotassique (Kcl : 20, 40 mM) , par la no- radrenalme (concentrations croissantes) , la sérotonine (concentrations croissantes) ...The contraction forces developed by the vascular rings in response to the various compounds are studied on quiescent or electrically stimulated vessels (5-8 Hz), using a hyperpotassic "polarizing" physiological solution (Kcl: 20, 40 mM), by the no-radrenalme (increasing concentrations), serotonin (increasing concentrations) ...
Les contractions sont exprimées en mg force ou en pourcentage de la contraction maximale a la dépolaπsa- tion par une solution "physiologique" hyperpotassique.The contractions are expressed in mg force or as a percentage of the maximum contraction upon depolation by a hyperpotassic "physiological" solution.
Les effets contractiles sont également mesurés in vi tro dans des conditions dynamiques de flux, par la pression développée par des réseaux vasculaires perfusés à débit constant.

Pharmacol. 1990, 99, 427-433) . La séparation des deux réseaux est réalisée en coupant les vaisseaux et les tissus le long de la bordure intestinale. Les réseaux sont perfusés à 2
JJContractile effects are also measured in vi tro under dynamic flow conditions, by the pressure developed by vascular networks perfused at constant flow. At the mesenteric level, vemoselectivity is studied on the model of double perfusion simultaneous and separate from arterial and venous networks, model developed by T. WARNER (British J. Pharmacol. 1990, 99, 427-433). The two networks are separated by cutting the vessels and tissues along the intestinal border. Networks are infused at 2 not a word

In vi vo, les pressions artérielles et veineuses sont mesurées chez l'animal anesthesie, dans des conditions basales et après arrêt circulatoire provoque par le gon¬ flement d'un cathéter a ballonnet introduit au niveau de l'oreillette droite. Lors de l'arrêt cardiaque, le tonus veineux (pression moyenne circulatoire de remplissage a volume sanguin constant) est calcule a partir des pres- sions veineuses et artérielles mesurées a l'équilibre et corrigées en fonction des différences relatives de com- pliance entre ces deux reseaux (SAMAR & COLEMAN, Am. J. Physiol. 1978, 234 :H94-100; YAMAMOTO et al., Am. J. Phy- siol. 1980, 238:H823-828) . Chez l'animal éveille, les pressions artérielles sont mesurées selon la méthode classique dérivée de Riva Rocci, par analyse de l'onde acoustique transmise au ni¬ veau artériel et transformée par un transducteur piezo céramique place sur la queue du rat, en aval d'un manchon gonfle automatiquement par un générateur de pressionIn vi vo, arterial and venous pressures are measured in anesthesia animals, in basal conditions and after circulatory arrest caused by the swelling of a balloon catheter introduced at the level of the right atrium. During cardiac arrest, the venous tone (mean circulatory filling pressure at constant blood volume) is calculated from the venous and arterial pressures measured at equilibrium and corrected according to the relative differences in compliance between these two networks (SAMAR & COLEMAN, Am. J. Physiol. 1978, 234: H94-100; YAMAMOTO et al., Am. J. Physol. 1980, 238: H823-828). In awake animals, arterial pressures are measured according to the classic method derived from Riva Rocci, by analysis of the acoustic wave transmitted to the arterial level and transformed by a piezo ceramic transducer placed on the tail of the rat, downstream of '' a sleeve inflates automatically by a pressure generator
Au niveau microcirculatoire, les variations de sec¬ tion vemulaire et arteriolaire sont étudiées m vivo dans le modèle de la chambre cutanée dorsale de hamster vigile, après enregistrement videomicroscopique (microscope Leitz Ergolux équipe d'une source halogène pour l'éclairage et une caméra video CDD noir et blanc HPR 610) et analyse informatique (logiciel Visicap, Pack ICAP) des images.At the microcirculatory level, the variations of vemular and arteriolar sec ¬ tion are studied in vivo in the model of the dorsal cutaneous chamber of a vigilant hamster, after videomicroscopic recording (Leitz Ergolux microscope equipped with a halogen source for lighting and a video camera Black and white CDR HPR 610) and computer analysis (Visicap software, ICAP pack) of the images.

Les rats (Wistars, 200 a 230 g) sont tondus sur leur paroi abdominale une heure avant le début de l'expeπmen- tation. Le produit a tester est injecte par voie î.p. ou per os 1 heure a 4 heures avant le sacrifice. Les rats sont anesthésies par un mélange d'halothane. Ensuite, ils reçoivent une injection intradermique sur l'abdomen de 0,10 ou 0,15 ml (soit pour l'histalme 6,7 ou 10 micro- grammes ) d'agent inflammatoire et une injection intra¬ veineuse d'un ml d'une solution de bleu Evans a 0,5 % dans la veine du pénis. Ces injections sont réalisées 30 minutes avant l'euthanasie.The rats (Wistars, 200 to 230 g) are shorn on their abdominal wall one hour before the start of the experiment. The product to be tested is injected i.p. or per hour 1 to 4 hours before the sacrifice. The rats are anesthetized with a mixture of halothane. Then, they receive an intradermal injection on the abdomen of 0.10 or 0.15 ml (that is to say 6.7 or 10 micrograms) of inflammatory agent and an intravenous injection of one ml d 0.5% Evans blue solution in the vein of the penis. These injections are given 30 minutes before euthanasia.
30 minutes après ces deux injections, les rats sont euthanasies par dislocation cervicale.30 minutes after these two injections, the rats are euthanized by cervical dislocation.
A l'endroit αe l'injection de l'agent inflammatoire, la peau est découpée et placée dans des tubes en verre a col rôde contenant 3 ml α' acide chlorhydrique fumant. La digestion de la peau est réalisée par un contact d'au moins une heure au bain marie a 37°C. Trois ml αe chlo¬ rure de benzalkonium a 12, 8O sont ensuite ajoutes. Apres avoir laisse reposer durant trente minutes, 7 ml de di- cnloromethane sont aαditionnes. Les tubes sont agites pé¬ riodiquement penαaπt une neure. La phase aqueuse est eli- mmee par aspiration et la phase organique "dichloro-
méthane" est filtrée. Les densités optiques sont quanti¬ fiées par spectrophotométrie d'absorption à une longueur d'onde de 620 nm, contre un blanc contenant uniquement le dichloromethane. Les moyennes des densités optiques des différents lots d'animaux traités ou témoins sont calculées, puis un pourcentage de variation des valeurs correspondant aux animaux traites par rapport à celles des animaux témoins est calculé. L'effet des composes sur l' hyperperméabilité induite par des agents inflammatoires, comme l'histamme et la braαykinme est également étudié après injection intra¬ veineuse par bolus αans le modèle de cnambre cutanée dor¬ sale de hamster et selon la méthode développée par GIMENO et al., décrite précédemment (A new technique using m- travital videomicroscopy for macromolecular permeability measurement, 18° Congres Européen de microcirculation, Rome 1994) par videomicroscopie et analyse d'images par quantification de la répartition de la fluorescence mtra et extravasculaire du marqueur fluorescent (FITC-Dextran) injecté en bolus par le cathéter jugulaire (63 mg/kg pour un volume défini a 1 ml/kg) . Le microscope est équipé d'une source fluorescente et d'une comomaison de filtres (excitation dans le bleu 450-490 nm et filtre d'arrêt 515 nm) .At the site of the injection of the inflammatory agent, the skin is cut and placed in glass tubes with a round neck containing 3 ml of fuming hydrochloric acid. The digestion of the skin is carried out by contact for at least one hour in a water bath at 37 ° C. Three ml of benzalkonium chloride at 12.880 are then added. After leaving to stand for thirty minutes, 7 ml of declorlorhane are added. The tubes are agitated periodically for one minute. The aqueous phase is removed by suction and the organic phase "dichloro- methane "is filtered. The optical densities are quantified by absorption spectrophotometry at a wavelength of 620 nm, against a blank containing only dichloromethane. The averages of the optical densities of the different batches of treated or control animals are calculated, then a percentage change in the values corresponding to the treated animals compared to those of the control animals is calculated.The effect of the compounds on the hyperpermeability induced by inflammatory agents, such as histamma and braαykinme is also studied after injection. intravenous by bolus in the golden hamster skin model and according to the method developed by GIMENO et al., described previously (A new technique using m- travital videomicroscopy for macromolecular permeability measurement, 18 ° European Congress of microcirculation, Rome 1994) by videomicroscopy and image analysis by quantification of the distribution of the f mtra and extravascular fluorescence marker (FITC-Dextran) injected as a bolus by the jugular catheter (63 mg / kg for a volume defined at 1 ml / kg). The microscope is equipped with a fluorescent source and a combination of filters (excitation in blue 450-490 nm and stop filter 515 nm).
Effets sur la résistance capillaire :Effects on capillary resistance:
L'augmentation de la résistance capillaire est ap¬ préciée par la modification de l'index pétéchial (pres¬ sion négative induisant l' extravasation des érythrocy- tes), mesuré par une méthode dérivée de l' angiosterro- mètre de Parrot .The increase in the capillary resistance is ap¬ préciée by the modification of the petechial index (negative pres ¬ sion inducing the extravasation of erythrocyte your) measured by a method derived from the angiosterro- meter of Parrot.
L'étude se réalise sur des rats mâles Wistar d'un poids moyen de 200 g (âgés d'environ six semaines) . La région du bas du dos est rasée puis épilée à l'aide d'une pâte à base d'un αéπve de l'acide thioglycolique et
d'hydroxyde de calcium. Apres environ trente minutes, la peau est abondamment rinçee et sechee.The study is carried out on male Wistar rats weighing an average of 200 g (around six weeks old). The region of the lower back is shaved and then depilated using a paste based on an αéπve of thioglycolic acid and calcium hydroxide. After about thirty minutes, the skin is thoroughly rinsed and dried.
Le jour de l'étude, les rats sont maintenus sans contrainte. Une dépression de 80 mm de mercure est appli- quee. Si les petechies (extravasation d' erythrocytes) ne sont pas apparues dans les 15 secondes, la dépression est augmentée par pallier en maintenant la ventouse au même endroit .On the day of the study, the rats were kept unconstrained. A vacuum of 80 mm of mercury is applied. If the petechies (extravasation of erythrocytes) have not appeared within 15 seconds, the depression is increased by compensating by keeping the suction cup in the same place.
La dépression minimale pour laquelle apparaissent les petechies exprime, en mm de mercure, la valeur de ré¬ sistance capillaire de base (avant tout traitement) . Deux mesures sont réalisées pour chaque essai a des emplace¬ ments différents du dos.The minimum depression for which the petechies appear expresses, in mm of mercury, the value of basic capillary resistance (before any treatment). Two measurements are made for each test at different locations on the back.
Les rats sont traites par voie orale. Apres un temps détermine (généralement 2, 4, 6 heures) suivant le trai¬ tement, le test est renouvelle sur des plages de peau différentes, jusqu'à l'apparition des petechies, procu¬ rant un nouvel index de dépression. Toutes les mesures se font en aveugle. Un pourcentage de variation des résistances capil¬ laires des animaux traites par rapport a leur résistance capillaire de base est calcule pour chague compose étu¬ die, a chaque temps de traitement et compare avec le groupe témoin (excipient seul) ou le groupe de référence. Effets sur la pleurésie induite chez le rat :The rats are treated orally. After a determined time (generally 2, 4, 6 hours) depending on the treatment, the test is repeated on different areas of skin, until the appearance of petechiae, providing a new index of depression. All measurements are made blind. A percentage change in the capillary resistance of the treated animals with respect to their basic capillary resistance is calculated for each study compound, at each treatment time and compared with the control group (excipient only) or the reference group. Effects on induced pleurisy in rats:
L'activité antimflammatoire des composes est égale¬ ment étudiée par la mesure de l' inhibition de l'oedème et de la migration leucocytaire après induction d'une pleu¬ résie chez le rat par injection de carraghenme dans la cavité pleurale (ALMEIDA et al., J. Pharmacol. Exp. The- rap., 1980, 214 :74) .The anti-inflammatory activity of the compounds is also studied by measuring the inhibition of edema and leukocyte migration after induction of rain in the rat by injection of carrageenan into the pleural cavity (ALMEIDA et al ., J. Pharmacol. Exp. Rap., 1980, 214: 74).
Les rats sont traites per os par les composes 2 heu¬ res avant l' injection de carraghenme, ainsi que 2 et 4 heures après cette injection. Apres un temps détermine (6 heures) suivant l'mαuction de la pleurésie, les rats
sont euthanasies et le liquide pleural récupéré par aspi¬ ration et son volume est mesure. Les cellules leucocytai¬ res sont comptées par "cell counter" .The rats are treated per os with the compounds 2 hours before the injection of carrageenan, as well as 2 and 4 hours after this injection. After a determined time (6 hours) following the induction of pleurisy, the rats are euthanized and the pleural fluid recovered by aspiration and its volume is measured. The leukocyte cells are counted by "cell counter".
Les résultats sont exprimés en nombre de leucocytes dans l'exudat rapporte a 100 g de poids αe l'animal et compares a ceux du lot témoin.The results are expressed in number of leukocytes in the exudate relative to 100 g of animal weight and compared to those of the control batch.

Par ailleurs, les composes de l'invention et leurs sels éventuels sont très peu toxiques. Par exemple, après une administration orale unique de 500 mg/kg chez la sou¬ ris, aucun effet toxique ooservable et aucune mortalité n'est observée pour la majorité des composes en particu-
lier pour l'Exemple c, l'Exemple d, l'Exemple 2, l'Exem¬ ple 3 (urines orangées) , l'Exemple 5.Furthermore, the compounds of the invention and their possible salts are very little toxic. For example, after a single oral administration of 500 mg / kg in the penny ¬ laugh, no ooservable toxicity and no mortality was observed for the majority of compounds espe- link for Example c, Example d, Example 2, Example 3 (orange urine), Example 5.
La plupart des composes se révèlent non cytotoxiques (la viabilité cellulaire étant mesurée par quantification de l'incorporation cellulaire de rouge neutre) jusqu'à des concentrations égales à leur solubilité en milieu aqueux sur des lignées cellulaires fibroblastiques de souris (L929) , en particulier l'Exemple c, l'Exemple 3, 1'Exemple 4 , l'Exemple 6. Parmi les composes préfères de l'invention, on re¬ tient tout particulièrement l'Exemple 3.Most of the compounds prove to be non-cytotoxic (cell viability being measured by quantification of the cellular incorporation of neutral red) up to concentrations equal to their solubility in aqueous medium on fibroblastic cell lines of mice (L929), in particular Example c, Example 3, Example 4, Example 6. Among the preferred compounds of the invention, there is very particularly Example 3.
Ce qui précède montre que les composes de l' inven¬ tion et leurs sels éventuels peuvent être utilises en thérapeutique humaine et animale. Ils sont en particulier indiques dans l'insuffisance veineuse fonctionnelle, or¬ ganique et les pathologies hemorroidaires par leurs com¬ posantes vasculaires et antunflammatoires, ainsi que dans les affections typiquement inflammatoires et dans les états de chocs constitues par une chute importante de la pression artérielle. Dans ce dernier cas, une amélio¬ ration du retour veineux est susceptible de maintenir le αebit cardiaque et des lors par voie de conséquence la pression artérielle.The above shows that the compounds of the invention and their possible salts can be used in human and animal therapy. They are particularly indicated in functional, organic venous insufficiency and hemorrhoidal pathologies by their vascular and anti-inflammatory components, as well as in typically inflammatory conditions and in shock states constituted by a significant drop in blood pressure. . In the latter case, an improvement in venous return is likely to maintain the cardiac output and consequently blood pressure.
L'insuffisance veineuse fonctionnelle se caractérise par une dilatation et une hyperdistensibilite des veines superficielles des membres inférieurs, oedèmes, paresthe- sies a type d'impatience, de jambe sans repos. Ce type de pathologie peut évoluer vers l' insuffisance veineuse or¬ ganique caractérisée par le développement de varices, d'incontinences valvulaires, voire vers la phlébothrom- bose et les troubles trophiques aboutissant a des lésions ulcéreuses .Functional venous insufficiency is characterized by dilation and hyperdistensitivity of the superficial veins of the lower limbs, edemas, impatience type paresthesias, restless leg. This type of pathology can progress towards organ venous insufficiency characterized by the development of varicose veins, valve incontinence, even towards phlebothromobosis and trophic disorders leading to ulcerative lesions.
Dans cette pathologie veineuse, une composante in¬ flammatoire s' installe dans les premiers stades et se ma- nifeste plus clairement dans les stades avances.
Par leurs effets vemoconstπcteurs, anti-inflamma- toires en particulier sur l'hyperperméabilité vasculaire et leurs effets contractiles sur les artères cérébrales, les composés de l'invention et leurs sels éventuels sont également indiques dans la migraine.In this venous pathology, an inflammatory component settles in the early stages and manifests itself more clearly in the advanced stages. By their vemoconstπcteurs, anti-inflammatory effects in particular on vascular hyperpermeability and their contractile effects on the cerebral arteries, the compounds of the invention and their possible salts are also indicated in migraine.
