Description

TOLPERISONE AND SELECTIVE COX-2 INHIBITOR COMBINATIONS
Field of Invention
The present invention relates to pharmaceutical combinations comprising tolperisone or a pharmaceutically acceptable salt, solvate, polymorph, isomer, enantiomer or rasemic mixture thereof and selective COX-2 inhibitors or pharmaceutically acceptable salts, solvates, polymorphs, isomers, enantiomers or rasemic mixtures thereof.
The background of the invention
A muscle relaxant is a drug that affects skeletal muscle function and decreases the muscle tone. It may be used to alleviate symptoms such as muscle spasms, pain, and hyperreflexia. The term "muscle relaxant" is used to refer to two major therapeutic groups: neuromuscular blockers and spasmolytics. Neuromuscular blockers act by interfering with transmission at the neuromuscular end plate and have no central nervous system (CNS) activity. They are often used during surgical procedures and in intensive care and emergency medicine to cause temporary paralysis. Spasmolytics, also known as centrally acting muscle relaxants, are used to alleviate musculoskeletal pain and spasms and to reduce spasticity in a variety of neurological conditions. While both neuromuscular blockers and spasmolytics are often grouped together as muscle relaxants, the term is commonly used to refer to spasmolytics only.
Tolperisone is a centrally acting muscle relaxant that has been used for the symptomatic treatment of spasticity and muscle spasm. It acts at the reticular formation in the brain stem by blocking voltage-gated sodium and calcium channels and it is marketed unders trade names including Biocalm, Muscodol, Mydeton, Mydocalm, Mydoflex, Myolax, Myoxan and Viveo.
Its chemical name is 2-methyl-1 -(4-methylphenyl)-3-piperidin-1 -ylpropan-1 -one and its chemical structure is shown in the Formula 1 .
Formula 1. Tolperisone On the other hand, non-steroidal anti-inflammatory drugs (NSAIDs) are a very commonly prescribed type of drug that can reduce pain, inflammation and also lower the body’s temperature during a fever. NSAIDs work by inhibiting an enzyme called cyclooxygenase (COX). This enzyme is essential for the production of chemicals called prostaglandins, which are substances that have a few different roles, one of which is to cause inflammation. By stopping the enzyme, fewer prostaglandins are produced leading to less inflammation and pain.
The cyclooxygenase (COX) enzyme is actually present in two different forms, COX-1 and COX-2, each with a similar but distinct set of actions. COX-2 is the enzyme responsible for inflammation and fever, whereas COX-1 actually performs other functions such as protecting the gastric mucosa (the lining of the stomach) from the acid that the stomach naturally produces. COX-1 also plays a role in making platelets stick together to form clots. Both reduce blood flow to the kidneys.
One of the problems with most of the NSAIDs is that they block both types of the COX enzyme, so while inflammation and pain were reduced, so were some of the good effects of prostaglandins such as protection of the stomach lining. There are also NSAIDs, namely selective COX-2 inhibitors, which only target the COX-2 enzyme that is responsible for pain and inflammation, without impacting the production of protective factors for the stomach. Thus, it can be said that the selective COX-2 inhibitors are much more safe drugs, comparing with the classical non-selective NSAIDs in the treatment of inflammatory diseases.
Besides, recognition of new avenues for selective COX-2 inhibitors in cancer chemotherapy and neurological diseases such as Parkinson and Alzheimer’s diseases still continues to attract investigations on the development of selective COX-2 inhibitors. However, the recent market removal of some selective COX-2 inhibitors such as rofecoxib due to its adverse cardiovascular side effects clearly encourages the researchers to explore and evaluate alternative templates with COX-2 inhibitory activity.
In the state of art, there are few patent documents suggesting combinations of muscle relaxants and NSAIDs. For example, in the patent application numbered WO860368, it is stated that formulations of muscle relaxants and analgesics provide greater benefit in patients with acute musculoskeletal problems than similar doses of analgesics alone. However, types of NSAIDs and the risks thereof are not emphasized and differentiated in this document. Even so, the danger of the use of non-selective NSAIDs in patients with gastrointestinal disease stories is included in the common general knowledge.
Specific combinations of tolperisone and an active agent selected from NSAIDs or other than NSAIDs are also present in the prior art. For instance, the patent document numbered EP1610785B1 reveals the combined effect of tolperisone and dextromethorphan on the treatment of spasticity and pain. In another patent document numbered EP1677787B1 , the combination of tolperisone and flupirtin is suggested for the treatment of pains accompanied by an increase in muscle tone.
Considering the state of art, there is still a need for a dosage form, comprising tolperisone and a selective COX-2 inhibitor combination which enhance the therapeutic effect on spasmodic and arthritic disorders and ensures the gastrointestinal and cardiovascular safety and compliance of the patient at the same time.
Objects and Brief Description of the Invention
The main object of the present invention is to obtain combinations comprising tolperisone or a pharmaceutically acceptable salt, solvate, polymorph, isomer, enantiomer of rasemic mixture thereof and selective COX-2 inhibitors or pharmaceutically acceptable salts, solvates, polymorphs, isomers, enantiomers of rasemic mixtures thereof, eliminating all aforesaid problems and bringing additional advantages over the relevant prior art.
Another object of the present invention is to obtain compositions of tolperisone and selective COX-2 inhibitors ensuring cardiovascular and gastrointestinal safety and patient compliance, accordingly.
A further object of the present invention is to develop compositions of tolperisone and selective COX-2 inhibitors ensuring high stability, bioavalibility.
A further object of the present invention is to develop compositions of tolperisone and selective COX-2 inhibitors having an improved level of dissolution rate and solubility. Another object of the present invention is to provide a tablet dosage form comprising tolperisone and a selective COX-2 inhibitor for use in the treatment and prevention of spasmodic and arthritic disorders.
