Definitions
- the invention relates to a pain medication, consisting of the two components diazepam and diclofenac sodium, for use for migraines, acute severe back pain, significant joint problems and for a variety of other pain conditions. It is very powerful and replaces morphine treatments. It is given short-term or long-term and should not be taken with other medicines.
- the two components have long been known and widely used.
- Diazepam was invented in 1950 and has been marketed under the trade name Valium since 1963. In addition to its use for the symptomatic treatment of acute states of tension, excitement and anxiety, diazepam is used in premedication before surgical and diagnostic interventions. It is also used as a muscle relaxant and as an emergency therapeutic agent for the prophylaxis and anticonvulsive treatment of epileptic grand mal seizures and for the therapy of fever cramps that occur in children. These applications are well known and can be looked up at Wikipedia at any time. Applications for migraines, acute severe back pain and significant joint discomfort are not known for diazepam alone.
- Diclofenac Sodium does not belong to any of the aforementioned classes of substances.
- Diazepam is broken down by the cytochrome P450 enzyme system. Inhibitors of this enzyme system lead to a slower breakdown of diazepam combined with its prolonged or intensified effect. Diazepam also increases the effects of other muscle relaxants as well as the effects of nitrous oxide and analgesics.
- diazepam acts as an allosteric modulator of the GABA A receptor and increases the inhibitory effect of the neurotransmitter GABA.
- diazepam binds to the benzodiazepine binding site of this receptor and thus affects its conformational change. This increases the receptor sensitivity to GABA.
- An increased GABA activity results in an increased opening rate at the chloride channel and thus in an increased influx of chloride ions into the cell. The increase in the intracellular chloride concentration leads to a reduced excitability of the cell due to hyperpolarization.
- diclofenac In contrast, the effects of diclofenac, invented in 1965, are based on the inhibition of cyclooxygenase and thus reduced prostaglandin synthesis. The reason for this is an inhibition of the cyclooxygenases COX-1 and COX-2, which can no longer produce inflammatory prostaglandins.
- Diclofenac may be directly involved in lipoxygenase metabolism and suppress the formation of leukotrienes.
- the analgesic effect of diclofenac is increased by piperine, an ingredient in pepper.
- Diclo fenac is offered as a salt with sodium or potassium. The present invention relates only to the sodium salt diclofenac sodium.
- diclofenac Many undesirable effects have also become known for diclofenac. The most common are indigestion, water retention, high blood pressure, rash, headache, dizziness, and drowsiness.
- Diclofenac is one of the non-steroidal anti-inflammatory drugs, or NSAIDs (non-steroidal anti-inflammatory drugs) for short. This technical term means that it is an anti-inflammatory agent, but neither a cortisone preparation nor a morphine derivative. Diclofenac has an analgesic and anti-inflammatory effect and also lowers fever. Diclofenac is also known to be used against migraines. Diclofenac potassium, for example, as Voltaren K Migraine 50 mg coated tablets, is prescribed for migraines.
- WO 02/11700 A1 describes an external application of a combination of dia zepam and diclofenac, the product being present in the preparation at 1 percent. The product had to be rubbed onto the affected area. It is clear that an application for joint pain, migraines and back pain is out of the question, as this pain is not caused by superficial muscles and an applied solution would not bring any relief, although voltaren ointment with the main component diclofenac is said to act on joint pain. On the other hand, the problem of side effects does not arise from a purely external application.
- diclofenac binds to site II of HSA, the human serum protein, and not to site I.
- diazepam and diclofenac compete for this binding and diazepam displaces diclofenac.
- the concentration of free diclofenac in the blood rises again because it is not firmly bound by the HSA and can therefore better penetrate tissue in order to develop its effect.
- the study does not recognize, however, that diclofenac and dia zepam interact, but rather concludes the effectiveness of the method to observe the HSA binding when using a combination of diclofenac with nabumetone.
- diclofenac With an increase in the concentration in the blood is not a matter of course, because diazepam can just as well displace the active ingredient diclofenac from other receptors that are built similar to HSA Site II. Then diclofenac would be able to accumulate better in the tissue, but this would not require a better mechanism of action. The inhibition of cyclooxygenase and thus of the reduced prostaglandin synthesis would therefore neither be increased nor more targeted.
- diclofenac The release of diclofenac by diazepam also affects metabolism. Free diclofenac, like free diazepam, is broken down more quickly if the breakdown mechanism is not also blocked.
- the rate-limiting degradation step for diclofenac is determined by the enzyme CYP2C9, for diazepam it is CYP2C19, both of which are enzymes of the cytochrome P450 enzyme system. There does not seem to be any mutual influence here. It should be emphasized, however, that a large number of other common drugs and some foods can have a considerable influence here. This applies to commercially available proton pump blockers that are used to compensate for the digestive complications of diclofenac, as well as antidepressants, agents that modify blood pressure and other NSAIDs. It is therefore advisable not to take any further medication or to temporarily stop taking it under medical supervision.
- the pain receptors respond when it gets too hot or too cold, or a certain pressure is exceeded, or a chemical irritation occurs, for example when chemical substances are released during an inflammation.
- the object of the invention is therefore to provide a new pain medication for symptomatic control and lasting healing of moderate to very severe pain.
- pain is usually classified on a pain scale from 0 to 10.
- a pain scale with 10 levels is to be used to describe the pain severity according to www.ratgeber-ache.de/ache/definition/ritiskala/, whereby internationally used scales are similar, but all suffer from the general lack of objective measurability usually have to be determined subjectively:
- Moderate pain if the patient is distracted, he can ignore it for some time, but it is always noticeable.
- Moderate pain Sufferers can ignore it for a few minutes at most and have to make an active effort if they want to concentrate on work or participate in social activities.
- Moderate pain disturbs the patient in all normal everyday activities; it is difficult to concentrate.
- Severe pain dominates the perceptions; social contacts and the
- the invention mainly relates to pain levels 5 to 10, but is also suitable and useful for lower levels of pain in the case of a low dose.
- tumor pain or pain related to tumors including cancer and metastases
- the administration is preferably carried out orally in the form of tablets or capsules. However, it can also take the form of an injection, infusion, drops or a drinking ampoule.
- Each of these forms of administration has advantages and disadvantages, administration as an injection or infusion leads to a rapid onset of action, but the effect wears off early. Tablets or capsules that are packaged as sustained-release tablets can cover different periods of action. This principle is already well known with Voltaren Resinat and can also be used to advantage with the combination preparation.
- the administration as drops has the advantage of fine metering and subsequent metering, however, it must be ensured that no segregation or flocculation takes place in the embedding liquid, which the pharmacist or the user must take into account accordingly.
- liquid template make sure that it should not contain any active ingredients, but only substances that are inert in the body, such as water or propylene glycol, which can dissolve diclofenac sodium and diazepam equally.
- the dosage depends on the severity of the pain and corresponds to the usual dosages when the individual substances are used orally or otherwise
- the standard dose contains 5 mg diazepam and 75 mg diclofenac sodium.
- the dose may vary in children, the elderly and with pre-existing conditions and is between 1 mg to 100 mg diazepam and 1 mg to 150 mg diclofenac sodium.
- the application is short-term or long-term. As a short-term application for a few hours to a few days is provided. For long-term use, it can be taken for several weeks as prescribed by a doctor. For pain of pain severity 1 to 5, a standard dose should be taken once or twice a day, for pain severity 5 to 8 two to three times per day, and for pain severity 8 to 10 two to four times per day to take a standard dose.
- Dosage initially 75 mg diclofenac sodium + 5 mg diazepam as a tablet twice a day, after improvement on the pain scale 1-5 Reduction to once a day, total duration one week,
- Dosage 75 mg diclofenac sodium + 5 mg diazepam as a tablet twice a day for 1 week, after which no further intake was necessary.
- One advantage of the invention is that in this way the administration of opioids such as morphine can be avoided even in the case of very severe pain of pain severity 8 to 10. Another advantage is that pain can be relieved or healed over the long term. Long-term intake can usually be dispensed with; continuation is only necessary if the symptoms return due to stress or shock.
