Definitions

  • the present invention relates to a pharmaceutical combination comprising dimethyl fumarate and at least one muscle relaxant agent.
  • MS Multiple Sclerosis
  • CNS central nervous system
  • Myelin provides a covering or insulation for nerves, improves the conduction of impulses along the nerves and also is important for maintaining the health of the nerves.
  • inflammation causes the myelin to disappear. So, the electrical impulses become slower.
  • the nerves themselves are damaged. Patient suffers from a range of symptoms which affect their health-related quality of life such as pain, muscle spasticity and spasm, bladder problems and sleep disturbance.
  • MS Multiple sclerosis
  • MS is the most common autoimmune disorder affecting the central nervous system.
  • Multiple sclerosis also known as disseminated sclerosis or encephalomyelitis disseminata
  • MS is a demyelinating disease in which the insulating covers of nerve cells in the brain and spinal cord are damaged. This damage disrupts the ability of parts of the nervous system to communicate, resulting in a wide range of signs and symptoms, including physical, mental and sometimes psychiatric problems.
  • MS takes several forms, with new symptoms either occurring in isolated attacks (relapsing forms) or building up over time (progressive forms). Between attacks, symptoms may disappear completely; however, permanent neurological problems often occur, especially as the disease advances.
  • DMF Dimethyl fumarate
  • E dimethyl (E)- butenedioate
  • MS multiple sclerosis
  • TECFIDERA ® Dimethyl Fumarate is marketed by BIOGEN under the trademark TECFIDERA ® .
  • This formulation, TECFIDERA ® is available as hard gelatin delayed-release capsules containing 120 mg or 240 mg of granulated dimethyl fumarate enterical coated minitablets.
  • the strategy to improve the current state of MS treatment is to combine therapies.
  • Muscle relaxants are used to relieve muscle spasms which may result from some conditions which affect the nervous system. Conditions which may cause muscle spasms include multiple sclerosis, motor neuron disease and cerebral palsy. Muscle spasms and tightness may also follow long-term injuries to the head or back. Muscle spasm can also occur as part of a more short-term condition or injury, such as low back pain or whiplash. Medication helps the muscles to relax, which may also reduce pain and discomfort.
  • the muscle relaxant agent is selected from the group comprising tolperisone or tizanidine or baclofen or thiocolchicoside or diazepam or metaxalone or methocarbamol or dantrolene or cyclobenzaprine or carisoprodol or tetrazepam or mixtures thereof.
  • Tolperisone is a centrally acting muscle relaxant that has been used for the symptomatic treatment of spasticity and muscle spasm. It acts as the reticular formation in the brain stem by blocking voltage-gated sodium and calcium channels and it is marketed under trade names including Biocalm, Muscodol, Mydeton, Mydocalm, Mydoflex, Myolax, Myoxan and Viveo.
  • tolperisone 2-methyl-1-(4-methylphenyl)-3-piperidin-1-ylpropan-1- one and its chemical structure is shown in the Formula II.
  • One of the other preferred muscle relaxant agent is tizanidine. Its chemical structure is shown in Formula III.
  • Tizanidine is a a2-adrenergic agonist and acts mainly at spinal and supraspinal levels to inhibit excitatory interneurons. It is used for the symptomatic relief of spasticity associated with multiple sclerosis or with spinal cord injury or disease.
  • the recommended dose of tizanidine is 2 mg, 4mg or 6 mg.
  • baclofen Another preferred muscle relaxant agent is baclofen.
  • the chemical name of baclofen is 4- amino-3-(4-chlorophenyl) butanoic acid and is generally represented as follows in Formula IV;
  • a further preferred muscle relaxant agent is thiocolchicoside. It is a muscle relaxant with anti inflammatory and analgesic effects and has been claimed to possess GABA-mimetic and glycinergic actions, in another way we can say that thiocolchicoside is a gamma-aminobutiric acid receptor agonist. Its chemical structure is shown in Formula V.
  • combining more than one molecule in one dosage form increases the patient’s compliance.
  • this combination increases the patients’ quality of life, combining more than one molecule in one dosage form also reduces undesired multiple sclerosis symptoms which can be muscle spasticity.
  • the muscle relaxant agents are tolperisone or tizanidine or baclofen or thiocolchicoside or mixtures thereof.
  • the main object of the present invention is to combine dimethyl fumarate with at least one muscle relaxant agent to eliminate multiple sclerosis symptoms, to provide rapid and effective treatment and to bring additional advantages over the relevant prior art.
  • Another object of the present invention is to obtain a stable combination formulation with synergistic effect for use in multiple sclerosis.
  • This invention also provides a pharmaceutical combination comprising an effective amount of dimethyl fumarate and an effective amount of at least one muscle relaxant agent for use in treating a human afflicted with multiple sclerosis, wherein dimethyl fumarate and at least one muscle relaxant agent are administered simultaneously, separately or sequentially.
  • tolperisone refers to tolperisone in the form of the free base or in the form of pharmaceutically acceptable salts, crystalline polymorph, solvates, hydrates, esters or mixture thereof.
  • tizanidine refers to tizanidine in the form of the free base or in the form of pharmaceutically acceptable salts, crystalline polymorph, solvates, hydrates, esters or mixture thereof.

  • thiocolchicoside refers to thiocolchicoside in the form of the free base or in the form of pharmaceutically acceptable salts, crystalline polymorph, solvates, hydrates, esters or mixture thereof.
  • Muscle relaxants are medicines that are used to prevent and reduce muscle spasms and tightness (spasticity). Muscle spasms occur when there is an uncontrolled (involuntary) contraction of a group of muscles. The muscles usually shorten (contract) suddenly; this is often painful. Spasticity occurs when some muscles contract tightly and can then become stiff and harder to use.
  • the pharmaceutical combination comprises dimethyl fumarate and at least one muscle relaxant agent.
  • the muscle relaxant agent is selected from the group comprising tolperisone or tizanidine or baclofen or thiocolchicoside or diazepam or metaxalone or methocarbamol or dantrolene or cyclobenzaprine or carisoprodol or tetrazepam or mixtures thereof.
