Definitions
- the present invention relates to the use of nicotinamide mononucleotide (NMN), one of its pharmaceutically acceptable derivatives or one of its pharmaceutically acceptable salts, as well as compositions comprising it, for the prevention and / or treatment of back pain, in particular of low back pain and chronic low back pain.
- NNN nicotinamide mononucleotide
- the spine is made up of 24 vertebrae including 7 cervical, 12 dorsal or thoracic and 5 lumbar, to which are added "welded" vertebrae that are the sacrum and the coccyx.
- the cervical, dorsal and lumbar vertebrae are separated by intervertebral discs and are said to be “mobile”.
- the spine is also connected with a set of ligaments and muscles.
- Back pain, and more exactly in the spine, is an increasingly frequent ailment and can result from various factors such as poor posture, carrying excessive loads or be the result of an underlying pathology.
- pathologies include wear and tear of the joints, pinching of nerve roots, osteoporosis, crushing or herniation of intervertebral discs, degeneration of intervertebral discs, deformation of the spine, tumor, trauma such as fracture from accident or osteoporotic fracture, muscle pain and other causes.
- the most frequent pain in the spine are pain felt in the cervical vertebrae called neck pain and pain in the lumbar vertebrae called back pain.
- the pain felt in the thoracic vertebrae is less frequent and is called back pain.
- the cervical vertebrae are the most vulnerable because they support and move the head. Neck pain is often caused by osteoarthritis, that is, wear and tear of the vertebrae and their cartilage, poor posture, pinching of the nerves between the vertebrae, a herniated disc, trauma or narrowing of the spinal canal.
- Low back pain is pain occurring in the lumbar vertebrae. Low back pain is most often not serious. Sedentary lifestyle, carrying heavy loads during a professional activity, bad posture or bad movement are examples of causes that can cause low back pain. Indeed, the lumbar vertebrae are constantly stressed and support a significant part of the body weight, which makes it a particularly fragile region of the body.
- Acute low back pain commonly known as lumbago or kidney disease, is pain that can last up to 4 weeks and may go away on its own.
- Chronic low back pain is constant pain that lasts three months or more.
- Low back pain can also be caused by a herniated disc. It occurs when part of the gel contained in the intervertebral disc protrudes outward and compresses the nerve roots.
- Low back pain can also be caused by a gynecological problem. Many women experience back pain periodically or constantly, due to painful periods, endometriosis, etc. The source of the pain is therefore not located in the lumbar region, but the pain still radiates to the lower back.
- Low back pain can also be caused by the sliding of one vertebra on another vertebra, called spondylolisthesis. This situation can occur due to a congenital weakness in the spinal structures or as a result of trauma.
- Low back pain can also be caused by arthritis, osteoarthritis or osteoporosis. If the osteoporosis of the spine is severe, it can cause a vertebral fracture. Some inflammatory rheumatism, such as ankylosing spondylitis, can also cause pain and stiffness in the lower back. In rare cases, low back pain can be caused by an abdominal aortic aneurysm, tumor, osteoporosis-related fracture, or infection.
- non-degenerative low back pain previously called specific low back pain or secondary low back pain known as symptomatic, linked to a traumatic, tumor, infectious or inflammatory cause
- degenerative low back pain the origin of which may associate one or more of the following causes: decogenic or facet or mixed, ligamentous, muscular, linked to a regional or global disorder of spinal statics; and (iii) low back pain unrelated to anatomical lesions.
- Discogenic low back pain is understood to mean low back pain associated with pain or injury to the intervertebral discs.
- Facet low back pain is understood to mean low back pain caused by injury or pain in the facet joints, that is, the movable joints of the spine that connect the vertebrae to each other.
- the treatment of such pain generally includes the administration of analgesics, nonsteroidal anti-inflammatory drugs (NSAIDs), cortisone or cortisone derivatives, by topical, oral or injectable route.
- NSAIDs nonsteroidal anti-inflammatory drugs
- cortisone or cortisone derivatives by topical, oral or injectable route.
- the present invention relates to nicotinamide mononucleotide (NMN), one of its pharmaceutically acceptable derivatives or one of its pharmaceutically acceptable salts, for its use by the topical route in the prevention and / or treatment of back pain.
- NNN nicotinamide mononucleotide
- the pharmaceutically acceptable derivative of NMN can be dihydronicotinamide mononucleotide (NMN-H).
- the pharmaceutically acceptable derivative of NMN can be alpha-NMN.
- the pharmaceutically acceptable derivative of NMN can be chosen from a compound of formula (I): or one of its stereoisomers, one of its salts, one of its hydrates, one of its solvates or one of its pharmaceutically acceptable crystals thereof, in which:
