Definitions
- the present invention relates to an analgesic comprising, as an active ingredient, a morphinan derivative having a nitrogen-containing cyclic substituent or a pharmacologically acceptable acid addition salt thereof useful for the treatment of pain.
- Pain develops when tissue is damaged due to illness or trauma, and local pain-producing substances are produced, or because there is no direct factor such as noxious stimulation, due to abnormal functioning of the nervous system, etc. It is known when it is caused. Pain is classified into three types: (1) nociceptive pain, (2) neuropathic pain, and (3) psychogenic pain. Can be separated. Nociceptive pain is pain caused by external force stimulation applied to a living body, such as trauma, or pain caused by a disease in an internal tissue. Many of these pains are transient and disappear when the underlying disease is cured, and can often be classified as acute pain.
- NSAIDs non-steroidal anti-inflammatory drugs
- acetaminophen which have an action point in the periphery
- Opioid analgesics represented by certain morphine have been used.
- peripheral analgesics such as NS AIDs
- opioid analgesics Nausea side effects such as vomiting, constipation, addiction are problems.
- these analgesics, including morphine are effective for acute pain but often are not effective for neuropathic and psychogenic pain. Therefore, it is desired to create a new analgesic agent that is effective not only for acute pain but also for chronic pain including pain that does not work with morphine and has few side effects.

- Diabetes-induced rats were purchased from Japan SLC (Streptozotocin (STZ) 50 mg / kg, single intraperitoneal administration at 6 weeks of age). At 3 weeks after STZ administration, the blood glucose level was measured with a precision Q ⁇ I ⁇ D blood glucose meter, and those with a value of 200 mg / dL or more were judged to induce diabetes. Diabetes-induced animals are Dixson using 0.407, 0.692, 1.202, 2.041, 3.630, 5.495, 8.511, or 15.136 g of pressure-applying filament (North Coast Medical, Inc. CA, USA) after 4 weeks of STZ administration. This was evaluated according to the Up-Down method (Non-Patent Document 4).
- a polyethylene force tape (PE-50) for intravesical pressure measurement was inserted into the bladder transurethrally, and a polyethylene force tape for filling physiological saline from the top of the bladder. (PE-100) was inserted into the bladder.
- PE-50 polyethylene force tape
- PE-100 polyethylene force tape for filling physiological saline from the top of the bladder.
- Each catheter was tightly ligated so that physiological saline did not leak from the insertion site.
- a drug administration catheter was placed in the femoral vein. The skin on the flank was incised, and a bipolar electrode for electromyography was inserted into the lateral oblique muscle and placed. Connect a reservoir pre-filled with saline to an indwelling catheter Then, the bladder was extended by fixing at a specific height.
- the extension stimulation was 20 seconds, and the interval between repeated stimulations was 3 minutes.
- Bipolar electrode electroencephalogram needle, Nihon Kohden
- EMG100C EMG amplifier
- High cut filter 5 kHz
- low cut filter 100 Hz
- AD The device (MP-150WSW, Biopac systems) and computer were loaded at 1 kHz, and myoelectric activity was recorded using dedicated software (AcqKnowledge 3.8.1, Biopac systems).
- Intravesical pressure was measured using a pressure transducer (AP641G, Nippon Koden) and a general-purpose amplifier (DA100C, Biopac systems). After adjusting the halothane concentration and obtaining stable myoelectric activity by stretching 50 cmH 0, the drug is administered intravenously.
- the drug was dissolved in 5% xylitol-0.02% citrate aqueous solution, and the administration volume was 0.5 mL / kg.
- the change in the number of spikes after drug administration was standardized with the average value of the number of spikes due to bladder extension twice before drug administration as the pre-drug value and the pre-dose value as 100%.
- the mean value of the three spike count changes between 15 minutes after drug administration was calculated, and the drug effect was judged by Williams test.
- Drug dose Number of cases Myoelectric activity in the external oblique muscle (number of spikes) Inhibition rate (mg / kg, i v) (vs. pre-dose, 3 ⁇ 4)
- the analgesic of the present invention has a remarkably high analgesic action, and has various acute pain and chronic pain. It can be applied to pain.
