Background of the invention The treatment of pain conditions is of great importance in medicine. There is currently a world-wide need for additional pain therapy. The pressing requirement for a specific treatment of pain conditions or as well a treatment of specific pain conditions which is right for the patient, which is to be understood as the successful and satisfactory treatment of pain for the patients, is documented in the large number of scientific works which have recently and over the years appeared in the field of applied analgesics or on basic research on nociception. PAIN is defined by the International Association for the Study of Pain (IASP) as \"an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage ( IASP, Classification of chronic pain, 2nd Edition, IASP Press (2002), 210 ). Even though pain is always subjective its causes or syndromes can be classified. A long-standing way of treating pain - which is also currently the most common therapeutic approach - is the use of opioids, compounds binding to the receptors of the opioid system (µ, κ, δ and ORL1). These opioids have either been used in clinics or are under investigation with compounds binding to the µ-opioid receptor, like morphine, having currently the highest clinical relevance for the treatment of pain. Nevertheless, even though being highly effective as pain-killers, some of these µ-opioids (as they are also called) do show some severe drawbacks, namely dependency/addiction and tolerance. So, for some of these µ-opioids persons having been exposed for an extended time to compounds like morphine - especially in higher dosages - did show signs of addiction from continuous exposure. On the other hand, in some patients following a prolonged treatment with some of these µ-opioids like morphine the analgesic effect of the treatment severely declined, which is a dramatic situation for these patients given the circumstances of their suffering. Another aspect that was in the focus of this invention was breakthrough pain (BTP). In patients who have moderate to severe pain, two components are usually present: persistent pain (lasting 12 or more hours/day) and breakthrough pain (BTP), a transitory flare of pain of moderate to severe intensity occurring on a background of otherwise controlled pain. BTP has been reported in up to 86% of patients treated with around-the-clock (ATC) medications for their persistent pain. The onset of BTP is often sudden, reaches maximal intensity within 3 minutes, and lasts for a median duration of 30 minutes. Unfortunately, the medications currently used to treat BTP are often not adequate especially because the onset of pain relief is taking too long, or - in an attempt to to control the BTP in advance - has lead to overdosing of the patients. This has caused considerable research activity in the recent years including efforts being undertaken to develop new ways of applying the active ingredients. As pain, especially also breakthrough pain, is still considered a major health problem in broad areas of the population and needs a very specific treatment, it was the underlying problem solved by this invention to find new ways of treating pain. Especially it was the underlying problem solved by this invention to improve treatment with µ-opioids especially in regards to the risks of tolerance and addiction and/or allowing also the treatment of breakthrough pain. So, the main object of this invention is a combination of compounds comprising\n a) at least one compound A selected from benzyl-4,5-dihydro-1H-imidazole derivatives according to general formula (I)\n \nwherein R 1 is selected from hydrogen; or OH;in neutral form, the form of a base or acid, in the form of a salt, preferably a physiologically acceptable salt, in the form of a solvate or of a polymorph; \nand b) at least one compound B selected from compounds binding to an opoid receptor. The compound B may be in neutral form, the form of a base or acid, in the form of a salt, preferably a physiologically acceptable salt, in the form of a solvate or of a polymorph and/or in the form of in the form of its racemate, pure stereoisomers, especially enantiomers or diastereomers or in the form of mixtures of stereoisomers, especially enantiomers or diastereomers, in any suitable ratio. While working on benzyl-4,5-dihydro-1 H-imidazole compounds and their combination with compounds binding to the opioid receptor (especially µ-opioids) it was surprisingly found out that the combination of these compounds either used simultaneously or consecutively could act on the treatment of pain with a high potency, especially showing a super-additive effect in a number of treatments in pain symptoms. Thus this combination was not only strongly ameliorating pain treatment, but seems also to be able to reduce the risk of the development of dependency in a patient especially by allowing a reduction in dose of the opioids and to reduce/deny the effect of development of tolerance. \"Treating\" or \"treatment\" as used in this application are defined as including the treatment of the symptoms of pain, as well as treatment of the disease or disease consequences causing the symptoms, the prevention or the prophylaxis of the symptoms of pain, as well as the prevention or the prophylaxis of the disease or disease consequences causing the symptoms. Preferably \"treating\" or \"treatment\" as used in this application are defined as including the treatment of the symptoms of pain, as well as treatment of the disease consequences causing the symptoms, the prevention or the prophylaxis of the symptoms of pain, as well as the prevention or the prophylaxis of the disease consequences causing the symptoms. Most preferably \"treating\" or \"treatment\" as used in this application are defined as including the treatment of the symptoms of pain, and the prevention or the prophylaxis of the symptoms of pain. \"Opioids\" is the common name for all compounds which have the same mode of action as the constituents of opium, the dried milky liquid of the poppy seed, Papaver somniferum (Brownstein, 1993). All opioids interact in biological systems with the same type of receptor, the so-called opioid receptor. According to the analgesia and side-effect profile four types of opioid receptors, the µ-receptor (ligand = morphine), the κ-receptor (ligand = ketazocine) and the δ-receptor, as well as the later-added ORL1-receptor are known. Corresponding to other receptor systems, binding studies as well as functional investigations indicate that subtypes of opioid receptors exist (Wood, 1982; Pasternak and Wood, 1986). Within the µ-and δ-receptor type 2 subtypes, the µ-1 and µ-2 and δ-1 and δ-2 have been described. The κ-receptor contains an additional κ-3 subtype. By definition all subtypes of the different opioid receptors are included in this invention. \"Compound binding to an opioid receptor\" as used in this application is/are defined as having a K i Value in their binding to at least one of the various opioid-receptor of ≤ 1 µM. \"Compound binding to the µ-opioid receptor\" as used in this application is/are defined as having a K i Value in their binding to the µ-opioid-receptor ≤ 1 µM. Assays that may be used for determining the affinity and selectivity of a compound binding to the µ-opioid receptor especially a µ-receptor agonist are well known in the art and especially measuring the affinities to these receptors are offered by a number of well-known service companies. A complete comprehensive list of compounds binding to opioid receptors, especially to the µ-opioid receptor, together with their Ki-values for different opioid receptors are given in H.Buschmann et al, Handbook of Pain, (2002), Wiley , and is hereby incorporated by reference and forms part of the disclosure. The term \"solvate\" according to this invention is to be understood as meaning any form of a compound in the invention in which this compound has attached to it via non-covalent binding another molecule (most likely a polar solvent) especially including hydrates and alcoholates, e.g. methanolate. The term \"salt\" is to be understood as meaning any form of compound A or compound B according to the invention in which it assumes an ionic form or is charged and is coupled with a counter-ion (a cation or anion) or is in solution. By this are also to be understood complexes of the active compound with other molecules and ions, in particular complexes which are complexed via ionic interactions. The term \"physiologically acceptable salt\" also means in the context of this invention any salt that is physiologically tolerated (most of the time meaning not being toxic- especially not caused by the counter-ion) if used appropriately for a treatment especially if used on or applied to humans and/or mammals. These physiologically acceptable salts can also be formed with anions or acids in the context of this invention is understood as meaning salts of at least one of the compounds used according to the invention - usually protonated, for example on the nitrogen - as the cation with at least one anion which are physiologically tolerated - especially if used on humans and/or mammals. By this is understood in particular, in the context of this invention, the salt formed with a physiologically tolerated acid, that is to say salts of the particular active compound with inorganic or organic acids which are physiologically tolerated - especially if used on humans and/or mammals. Examples of physiologically tolerated salts of particular acids are salts of: hydrochloric acid, hydrobromic acid, sulfuric acid, methanesulfonic acid, formic acid, acetic acid, oxalic acid, succinic acid, malic acid, tartaric acid, mandelic acid, fumaric acid, lactic acid, gluconic acid or citric acid. These physiologically acceptable salts can be formed with cations or bases and in the context of this invention is understood as meaning salts of at least one of the compounds used according to the invention - usually a (deprotonated) acid - as an anion with at least one, preferably inorganic, cation which is physiologically tolerated - especially if used on humans and/or mammals. The salts of the alkali metals and alkaline earth metals are particularly preferred, and also those with NH4, but in particular (mono)- or (di)sodium, (mono)- or (di)potassium, magnesium or calcium salts. The compound A or compound B of the invention may be in crystalline form or either as free compounds or as solvates and it is intended that those forms are within the scope of the present invention. Methods of solvation are generally known within the art. Suitable solvates are pharmaceutically acceptable solvates.

For the purpose of this invention included under this heading or to be treated as synonymous is \"Neurogenic Pain\" which is defined by the IASP as \"pain initiated or caused by a primary lesion, dysfunction or transitory perturbation in the peripheral or central nervous system\". One of the many reasons causing neuropathic pain is diabetes, especially diabetes II. According to the IASP \"allodynia\" is defined as \"a pain due to a stimulus which does not normally provoke pain\" ( IASP, Classification of chronic pain, 2nd Edition, IASP Press (2002), 210 ). According to the IASP \"hyperalgesia\" is defined as \"an increased response to a stimulus which is normally painful( IASP, Classification of chronic pain, 2nd Edition, IASP Press (2002), 211 ). In another preferred embodiment of the use according to the invention the neuropathic pain, is selected from central pain, hyperpathia, peripheral neuropathic pain or peripheral neurogenic pain, causalgia, hyperesthesia, neuralgia, neuritis, or neuropathy. According to the IASP \"central pain\" is defined as \"a pain initiated or caused by a primary lesion or dysfunction in the central nervous system\" ( IASP, Classification of chronic pain, 2nd Edition, IASP Press (2002), 211 ). According to the IASP \"causalgia\" is defined as \"a syndrome of sustained burning pain, allodynia and hyperpathia after a traumatic nerve lesion, often combined with vasomotor and sudomotor dysfunction and later trophic changes\" ( IASP, Classification of chronic pain, 2nd Edition, IASP Press (2002), 210 ). According to the IASP \"hyperesthesia\" is defined as \"increased sensitivity to stimulation, excluding the senses\" ( IASP, Classification of chronic pain, 2nd Edition, IASP Press (2002), 211 ). According to the IASP \"neuralgia\" is defined as \"Pain in the distribution of a nerve or nerves\" ( IASP, Classification of chronic pain, 2nd Edition, IASP Press (2002), 212 ). According to the IASP \"neuritis\" is defined as \"Inflammation of a nerve or nerves\" ( IASP, Classification of chronic pain, 2nd Edition, IASP Press (2002), 212 ). According to the IASP \"neuropathy\" is defined as \"a disturbance of function or pathological change in a nerve: in one nerve mononeuropathy, in several nerves mononeuropthy multiplex, if diffuse and bilateral, polyneuropathy\" ( IASP, Classification of chronic pain, 2nd Edition, IASP Press (2002), 212 ). According to the IASP \"hyperpathia\" is defined as \"a painful syndrome characterized by an abnormally painful reaction to a stimulus, especially a repetitive stimulus, as well as an increased threshold\" ( IASP, Classification of chronic pain, 2nd Edition, IASP Press (2002), 212 ). The IASP draws the following difference between \"allodynia\", \"hyperalgesia\" and \"hyperpathia\" ( IASP, Classification of chronic pain, 2nd Edition, IASP Press (2002), 212 ):\n TABLE-tabl0001 Allodynia Lowered threshold Stimulus and response mode differ Hyperalgesia Increased response Stimulus and response rate are the same Hyperpathia Raised threshold; Increased response Stimulus and response rate may be the same or different Another aspect of the ionvention refers to the use of at least one combination according to the invention for the manufacture of a medicament for the treatment of sleep disorder, shift worker syndrome, jet lag, depression, seasonal affective disorder, migraine, anxiety, psychosis, schizophrenia, cognition and memory disorders, neuronal degeneration resulting from ischemic events, cardiovascular diseases such as hypertension, irritable bowel syndrome, inflammatory bowel disease, spastic colon or urinary incontinence.

Pharmacological methods: Method 1: Hot-Plate Test MATERIAL AND METHODS Animals Male CD1 mice aged from 6 to 8 weeks old are used in these studies. Animals are housed in groups of five, provided with food and water ad libitum and kept in controlled laboratory conditions with the temperature maintained at 21 ± 1 °C and light in 12 h cycles (on at 07:00 h and off at 19:00 h). Experiments are carried out in a soundproof and air-regulated experimental room. The number of mice ranges from 8 to 16 per group in each individual experiment. Drugs Drugs used for treatments are: Morphine and Xylometazoline as well as Oxymetazoline. Doses are calculated based on the molecular weight of the free base or of the respective salts, where applicable. EXPERIMENTAL PROCEDURE: The analgesic activity of the inventive active substance combination is determined in male CDR1 following and adapting the description in the publication of G. Woolfe and A. D. MacDonald, J. Pharm. Exp. Ther. 1944, 80, pages 300-307 . The respective description of this publication is incorporated by reference and forms part of the present disclosure. In accordance to this test the mice are put onto a plate, which is heated to 50 °C and the time is determined until the mice showed signs of pain such as vigorous and repeated licking of the hind or front paws, jumping or pulling back the paws. The mice are kept on the hot plate for no longer than 40 seconds in order to avoid the development of cutaneous lesions. The vehicle, the active substances and the inventive active substance combination to be tested are administered - sometimes in differing concentrations - either by s.c. or by i.p. injection to different groups of mice. 0.5 hours after the administration the animals are put onto the hot plate and the time is measured until they show signs of pain, divided by Front Paw Licking (FPL), Hind Paw Licking (HPL) and Jumping, to allow conclusions on differentiations of pain types through the different pain symptoms/signs of pain. The analgesic efficacy of the active substances or active substance combination is calculated on the basis of the values obtained for the comparison group of mice to which is only administered the vehicle (baseline). By comparing to baseline (defined as 0% analgesia) and to a failure of pain signs (defined as 100% analgesia) Percentage of analgesia is determined. In some cases based on this calculation and with different concentrations of the active substances or active substance combination ED50 values are determined. Method 2: Tail Flick Test The test was performed as previously described ( Moncada et al. (2003), Eur. J. Pharmacol. 465, 53-60 ). Briefly, the animals (male CD1 mice) were restrained in a Plexiglas tube and placed on the tail flick apparatus (LI 7100, Letica, S.A., Spain). A noxious beam of light was focussed on the tail about 4 cm from the tip, and the tail flick latency was recorded automatically to the nearest 0.1 s. The intensity of the radiant heat source was adjusted to yield baseline latencies between 3 and 5 s; this intensity was never changed and any animal whose baseline latency was outside the pre-established limits was excluded from the experiments. In order to minimise injury in the animals, a cut-off time of 10 s was used. The animals received an injection of the vehicle (saline), and drug or drug combination under study, and tail flick latencies were measured at 45 min after drug or vehicle administration. Baseline tail flick latencies were recorded after saline/vehicle injection. By comparing to baseline (defined as 0% analgesia) and to a failure of pain reaction/tail flick (defined as 100% analgesia) Percentage of analgesia was determined. The examples and figures in the following section describing pharmacological trials are merely illustrative and the invention cannot be considered in any way as being restricted to these applications. Figures: \n Figure 1 ) Tail-Flick-Test: Xylometazoline and Oxymetazoline \n Figure 1 ) refers to Example 1), a Tail-Flick-Test. Male CD1 Mice were receiving i.p. injections of 5mg/kg of the tested substances xylometazoline and oxymetazoline 45 min before measurement. The Baseline was determined based on saline injection. \nOxymetazoline does show an effect whereas xylometazoline does not show a pronounced activity under this protocoll. Figure 2 ) Tail-Flick-Test: Morphine in combination with Xylometazoline and Oxymetazoline Figure 1 ) refers to Example 1), a Tail-Flick-Test. Male CD1 Mice were receiving s.c. injections of 2mg/kg morphine and i.p. injections of 5mg/kg of xylometazoline and oxymetazoline 45 min before measurement. The Baseline was determined based on saline injection. Both combination showed a clearly synergistic effect reaching nearly 100 % analgesia and especially a very pronounced increase over the low-dose morphine applied alone. Examples: PHARMACOLOGICAL EXAMPLES: P-Example 1: Tail-Flick-Test (Combination of Morphine + Xylometazoline and Oxymetazoline): Male CD1 Mice were receiving:\n s.c. injection of saline (vehicle/baseline); s.c. injections of 2 mg/kg morphine; i.p.-injection of 5 mg/kg xylometazoline; i.p.-injection of 5 mg/kg oxymetazoline; s.c. injections of 2 mg/kg morphine + i.p.-injection of 5 mg/kg xylometazoline; s.c. injections of 2 mg/kg morphine + i.p.-injection of 5 mg/kg oxymetazoline; The mice were placed 45 minutes after injection in the tail-flick apparatus.
