Definitions
- the present invention relates to a pharmaceutical modified release composition in capsules with coated microspheres comprising the combination of two active principles of radically different plasma concentration times, these are a relaxing muscle (tizanidine) and a non-steroidal anti-inflammatory analgesic (meloxicam) , pharmaceutically acceptable carriers or excipients; as well as a process for the manufacture of the composition and the use of said combination for the preparation of a medication with synergistic therapeutic activity indicated in the treatment of spasticity, disorders related to muscle and / or skeletal muscle disorders and pain in general of moderate to severe.
- two active principles of radically different plasma concentration times these are a relaxing muscle (tizanidine) and a non-steroidal anti-inflammatory analgesic (meloxicam) , pharmaceutically acceptable carriers or excipients; as well as a process for the manufacture of the composition and the use of said combination for the preparation of a medication with synergistic therapeutic activity indicated in the treatment of spasticity, disorders related to muscle and / or skeletal muscle disorders and pain in general of
- Muscle disorders are a widespread condition in the general population, causes stiffness, muscle contraction, pain and interferes with muscle movements and functions (ambulation, manipulation, balance, speech, swallowing, and others).
- Tizanidine is a centrally acting alpha 2-adrenergic agonist, it is well tolerated and beneficial in the treatment of muscular spasticity of different etiology.
- tizanidine decreases reflex activity, especially polysynaptic reflex activity; It can restore or improve presynaptic noradrenergic inhibition in spastic patients, relieves spasms and increased muscle tone caused by conditions such as multiple sclerosis or spinal injury.
- Tizanidine also has antispastic effects even on commonly used drugs, such as baclofen, diazepam or clonazepam, without causing the resistance effects of these drugs. Additionally, it has been observed that tizanidine may have other effects such as a decrease in rebound headache due to the detoxification of analgesics, it seems to be effective in the treatment of chronic headache, and apparently has diminished properties as a hypertensive agent.
- tizanidine After oral administration, tizanidine is completely absorbed, reaches its maximum plasma concentration (Cmax) in approximately 1.5 hours after the dose and has an approximate half-life of 2.5 hours.
- this drug should be administered every 6 or 8 hours and has a linear pharmacokinetics in the range of 1 to 20 mg.
- Excretion of tizanidine is carried carried out mainly in 60% in urine and about 20% in feces (PDR information, 2006).
- the dose depending on the condition, can be 2 mg 3 or 4 times a day or usually it can be more than 24 mg divided into administrations 3 to 4 times a day, the maximum recommended is 36 mg day.
- Tizanidine can cause side effects such as: vertigo and weakness, as well as dizziness, stomach upset, vomiting, tingling in the arms, legs, hands and feet, dry mouth, stronger muscle spasms and even muscle contraction severe
- Meloxicam is a non-steroidal anti-inflammatory analgesic (NSAIDs), a selective COX-II inhibitor, derived from enolic acid, has anti-inflammatory properties and a good tolerability profile. It is indicated for the treatment of acute and chronic rheumatoid arthritis, osteoarthritis (degenerative joint disease), shoulder and hip periarthritis, as well as muscle strains and gout attacks, treatment of inflammation and pain, pain with trauma, inflammatory processes of soft tissues (airways), gynecological conditions and primary dysmenorrhea.
- NSAIDs non-steroidal anti-inflammatory analgesic
- COX-II inhibitor derived from enolic acid
- the absolute bioavailability of meloxicam is 89% and it has been recorded that its pharmacokinetics after a Intravenous administration is linear in the range of 5 to 60 mg.
- the elimination half-life of meloxicam varies between 15 and 20 hours and it has been recorded that it is constant at the different therapeutic doses of meloxicam, indicating that the metabolism is linear in the therapeutic range of this drug (Gates et al., 2005 ; PDR Information, 2006).
- the maximum plasma concentration is reached between 4 and 5 hours after administration, indicating a slow absorption (Carrasco-Portugal et al., 2005). Additionally, a second concentration peak is observed between 12 and 14 hours after administration, which suggests gastrointestinal recirculation (PDR Information, 2006).
- the effective doses for therapeutic indications have been recorded as ⁇ 7.5 and 15 mg daily. It should be mentioned that it has been evaluated if 22.5 mg of meloxicam produce a greater effect. However, only an increase in adverse events was observed at the gastrointestinal level. Thus, the maximum recommended daily dose for meloxicam is 15 mg (Ahmed et al., 2005).
- FD ⁇ and the English Health Council indicate that the non-steroidal anti-inflammatories that are used today, the vast majority are responsible for gastric lesions.
- Meloxicam causes side effects and, like other NSAIDs, these effects are mainly symptoms gastrointestinal such as: heartburn, diarrhea, sore throat, cough, rhinorrhea (nasal discharge) as well as dyspepsia, nausea, vomiting, constipation, gastrointestinal ulcer, macro or microscopic bleeding of gastrointestinal origin, transient abnormalities of the parameters of liver function, alterations in renal function parameters, pruritus, skin rashes and photosensitivity.
- tizanidine acts centrally, its main site of action is the spinal cord, reducing muscle tone, in addition to its muscle relaxant properties also exerts a moderate central analgesic effect.
- Meloxicam acts on the inhibition of prostaglandins, acting mainly on coenzyme oxygenase II (COX-II), which is primarily responsible for pain, its low activity on COX-I decreases gastric and renal disorders.
- COX-II coenzyme oxygenase II
- the present formulation makes available a combination of synergistic effect with a non-steroidal anti-inflammatory analgesic relaxing muscle activity.
- Said formulation allows the treatment of muscle spasticity, disorders related to muscular and / or skeletal muscle disorders, as well as general moderate to severe pain in A single dose unit.
- This synergy can allow the dosage to be one to two times a day and / or the concentration of active ingredients in the formulation is reduced, with the benefit that this synergy of the formulation allows the reduction of adverse effects.
- the new combination has a synergistic effect that is observed in a greater relaxing muscle activity and anti-inflammatory analgesic effect.
- compositions refer to the following doses of tizanidine and meloxicam: 6mg and 7.5mg, 6mg and 15mg, 12mg and 15mg, respectively.
- the ratio between tizanidine and meloxicam would vary between 83% - 16%, that is, while tizanidine will vary between 0.5 to 36mg in each dose, meloxicam will vary between 2mg and 15mg.
- compositions comprising a muscle relaxant plus a non-steroidal anti-inflammatory analgesic.
- the skeletal muscle drug is selected from metocarbamol, carisoprodol or diazepam.

- Said international application describes formulations which include valdecoxib, celicoxib, paracoxib, etoricoxib or a mixture thereof as COX-II inhibitor. It is worth mentioning that all Examples included in application PCT / IB2004 / 001184 refer to valdecoxib. It is relevant to consider that the meloxicam compound is not mentioned in the text of this international application.
- the present invention unlike the cited in the international application PCT / IB2004 / 001184, specifically refers to capsules with modified release microspheres.
- the present invention comprises a relaxing muscle drug, specifically tizanidine, of modified release, in particular called “repeated release”, and a non-steroidal anti-inflammatory analgesic, specifically meloxicam, of immediate release.
- the way in which this formulation has been designed allows in the first phase the immediate release of meloxicam and a part of tizanidine between 40 and 60%, later, in not less than 2 hours, in a second phase the rest of tizanidine is released. With this The therapeutic scope is considerably improved and possible adverse effects are reduced as plasma tizanidine concentration is maintained and significant concentration variations are avoided.
- a continuous process was developed that does not include independent preforms. which results in a reduction of manufacturing times and costs.

- the proposed composition is an oral administration formulation that refers to a composition of a muscle relaxant drug plus an NSAID-type drug in presentation of modified-release capsules with coated microspheres.
- drug release There are two forms of drug release: (1) it is fast or immediate and (2) the forms of modified release which in turn are divided into sustained, programmed, repeated release, among others.
- Figure 1 describes an absorption curve that presents the immediate release pharmaceutical forms.
- the behavior of two drugs that reach their peak plasma concentration times at markedly different times is represented.
- “A” represents the behavior of a drug that reaches its maximum plasma concentration (Cmax) in a short time and “B” does so in a broader time. Therefore, to maintain the therapeutic effect of "A” during the time that the drug "B” does it is necessary to administer two doses of "A", which are represented in the graph as “Al” and "A2 ".
- modified release are those designed in such a way that the rate is modified or the place of release of the active ingredient with respect to the pharmaceutical forms of immediate release of the same active ingredient.
- One of the modalities of modified release is repeated release, which characterizes those extended release dosage forms that release fractions of the active substance at certain time intervals.
- FIG. 2 depicts the behavior of two drugs that reach their times. of maximum plasma concentration at markedly different times that have been co-administered, formulated in a repeated release pharmaceutical form where: "A” represents the behavior of a drug that reaches its Cmax in a short time and "B" the behavior of a drug reaches its Cmax in a markedly longer time.
- the drug "A” has two periods of release.
- the graph shows how "A” reaches a level of plasma concentration and, later, a second therapeutic dose of "A” is released, this time resembles the behavior of the drug "B".
- the process of the present invention is characterized in that the operating times are reduced, compared to a similar process where coatings are carried out separately from the active principles or another process where it is necessary to give a prior treatment to the assets to include them in the same formulation in the same enteric layer.
- the process of the present invention allows the release of the active substance tizanidine to be controlled without affecting the immediate release of meloxicam.
- tizanidine is presented in two different layers separated by a retarding polymeric film, each layer has one of about 3mg of active.
- this invention satisfactorily meets the uniformity of content and uniformity required doses.
- the process of the present invention decreases the release of powders, which results in high yields of the formulation.
- Another advantage of the process of the present invention is that it works at temperatures close to that of the environment, which implies energy savings and avoids possible degradation of the assets and excipients of the novel composition.
- the composition is repeated release, preferred embodiment of this invention and is characterized in that it is composed of a microsphere coated with polymeric layers (semipermeable membrane) on an inert core;
- the diffusion of the drug depends on the type of membrane, the thickness, the pH at which it is found and the place where the drug should be released.
- the layers are composed of an adhesive polymer preferably Hydroxypropylmethylcellulose (HPMC) plus the drug, followed by an insoluble film in acidic or semipermeable pH and finally a second layer of the adhesive polymer.
- HPMC Hydroxypropylmethylcellulose
- the present invention relates to a pharmaceutical capsule composition characterized in that the coated microspheres comprise:
- the first film contains the part of the drug that is released in a delayed manner and the third film is composed of the two active ingredients to be released quickly or immediately.
- Figure 3 shows the design of the composition that presents the microsphere of the invention where: "A” is the inert core; “B” is the first film formed by tizanidine or its pharmaceutically acceptable salts (between 40 and 60% of the total tizanidine in this film), at least one adhesive polymer and at least one plasticizing agent; “C” is the second polymeric retarding film, at least one plasticizing agent and regulatory solution; and “D” is the third film formed by meloxicam, tizanidine (between 40 and 60% of the total tizanidine in this film) or its pharmaceutically acceptable salts, at least one adhesive polymer, at least one plasticizing agent, at least one surface active agent and other excipients.
- A is the inert core
- B is the first film formed by tizanidine or its pharmaceutically acceptable salts (between 40 and 60% of the total tizanidine in this film), at least one adhesive polymer and at least one plasticizing agent
- C is the second polymeric retarding film, at least one plasticizing agent and regulatory
- a medicament is formulated in the form of microspheres (inert nuclei) with relatively low dose active ingredients, particularly the tizanidine which is the lowest concentration active, which is divided into two layers or films.
- active ingredients particularly the tizanidine which is the lowest concentration active, which is divided into two layers or films.
- Working with relatively low concentrations of assets (6 mg) involves a number of difficulties, especially when it comes to controlled release, since it is necessary to ensure that said asset is distributed evenly. To achieve this, it is important to determine the operational and process conditions that allow us to efficiently adhere to said asset.
- quantifying "in vitro" the release of the asset requires the development of an analytical methodology sensitive enough to quantify low concentrations.
- the formulation in tablets and capsules with modified release microspheres as well as the manufacturing process of the pharmaceutical combination tizanidine and meloxicam is described below.
