In some embodiments, the pain is inflammatory pain.

Meloxicam and some other NSAIDs, and other drugs, have poor aqueous solubility which may reduce bioavailability and slow the onset of pain relief. One method of increasing the solubility and bioavailability of meloxicam or another drug is through the use of cyclodextrins in combination with meloxicam.

The invention provides a solid oral dosage form comprising: an inclusion complex of meloxicam and a sulfobutyl ether β-cyclodextrin (SBEβCD), wherein the solid dosage form contains about <NUM> of the meloxicam or a molar equivalent amount of a salt thereof; a bicarbonate; and about <NUM> of rizatriptan or a molar equivalent amount of a salt thereof. Rizatriptan is a triptan. Other triptans are sumatriptan, naratriptan, eletriptan, donitriptan, almotriptan, frovatriptan, alvitriptan, and zolmitriptan. However, in the invention, the triptan is rizatriptan, which has the structure as shown below.

<CHM>.

Meloxicam exhibits anti-inflammatory, analgesic, and antipyretic activities. The meloxicam mechanism of action may be related to the inhibition of prostaglandin synthetase (cyclo-oxygenase, COX) which is involved in the initial steps of the arachidonic acid cascade, resulting in the reduced formation of prostaglandins, thromboxanes and prostacylin.

In the invention, the dosage form is given orally.

The term "treating" or "treatment" broadly includes any kind of treatment activity, including the diagnosis, cure, mitigation, or prevention of disease in man or other animals, or any activity that otherwise affects the structure or any function of the body of man or other animals.

For example, although the underlying disease may not improve, or may continue to progress, an individual suffering from the disease may experience pain relief. The pain may affect a muscle, nerve, cartilage, bone, ligament, tendon, tendon sheaths, bursae, or joint.

Migraine is a headache disorder characterized by recurrent headaches that may be moderate to severe. The headaches may affect one half of the head, may be pulsating in nature, and may last from <NUM> to <NUM> hours. Associated symptoms may include nausea, vomiting, and sensitivity to light (photophobia), sound (phonophobia), or smell. The pain can be made worse by physical activity.

In the invention, the meloxicam is in an inclusion complex with a sulfobutyl ether β-cyclodextrin (SBEβCD). A sulfobutyl ether β-cyclodextrin (SBEβCD), which isa cyclodextrin Cyclodextrins (also known as cycloamyloses) are generally cyclic polysaccharides which form a bucket-like shape. Cyclodextrins help to increase bioavailability of other molecules because cyclodextrins are hydrophobic on the inside and hydrophilic on the outside which helps to facilitate the transport of hydrophobic molecules to a hydrophilic medium. The naturally occurring cyclodextrins include six, seven, and eight glucose units (α, β, and γ-cyclodextrin, respectively). However, synthetic cyclodextrins containing more or less glucose units are possible. In aqueous solutions, cyclodextrins can form complexes (i.e., an inclusion complex) with drugs by incorporating the drug into the center/hydrophobic portion of the cyclodextrin ring; although cyclodextrins are also known to aggregate around a drug in a micelle-type structure. This ability of cyclodextrins may allow them to act as carriers of less soluble drugs to increase the drugs' bioavailability.

The inclusion complex of the invention may be more water-soluble relative to the non-complexed drug. The cyclodextrin of the invention is a sulfobutyl ether β-cyclodextrin (SBEβCD). The cyclodextrin Cyclodextrins also include a naturally-occurring cyclodextrin (e.g., α, β, or γ-cyclodextrins) or a synthetic cyclodextrin. α-Cyclodextrins, derivatives, or salts thereof. α-Cyclodextrins may include, but are not limited to, (<NUM>,<NUM>,<NUM>-tri-O-acetyl)-α-cyclodextrin, (<NUM>,<NUM>,<NUM>-tri-O-methyl)-α-cyclodextrin, (<NUM>,<NUM>,<NUM>-tri-O-octyl)-α-cyclodextrin, <NUM>-bromo-<NUM>-deoxy-α-cyclodextrin, <NUM>-iodo-<NUM>-deoxy-α-cyclodextrin, (<NUM>-O-tertbutyl-dimethylsilyl)-α-cyclodextrin, butyl-α-cyclodextrin, succinyl-α-cyclodextrin, (<NUM>-hydroxypropyl)-α-cyclodextrin, or combinations thereof.

The dosage form includes a bicarbonate, such as sodium bicarbonate, potassium bicarbonate, etc. A bicarbonate may help to increase the pharmacokinetics or bioavailability of meloxicam or rizatriptan.

Enhancing bioavailability of meloxicam or rizatriptan in the dosage form may allow a reduced molar amount of the drug to be used as compared to other dosage forms containing the drug in treating diseases or disorders.

Use of the claimed cyclodextrin or bicarbonate may improve the oral bioavailability (e.g. a higher Cmax and/or higher AUC) of meloxicam in a subject (human or animal) by at least about <NUM>%, at least about <NUM>%, at least about <NUM>%, at least about <NUM>%, at least about <NUM>%, at least about <NUM>%, at least about <NUM>%, at least about <NUM>%, at least about <NUM>%, up to about <NUM>%, up to about <NUM>%, or any amount in a range bounded by, or between, any of these values as compared to administration of meloxicam alone.

Use of the claimed cyclodextrin or a bicarbonate may improve the oral bioavailability (e.g. a higher Cmax and/or higher AUC) of rizatriptan in subject (human or animal) by at least about <NUM>%, at least about <NUM>%, at least about <NUM>%, at least about <NUM>%, at least about <NUM>%, at least about <NUM>%, at least about <NUM>%, at least about <NUM>%, at least about <NUM>%, up to about <NUM>%, up to about <NUM>%, or any amount in a range bounded by, or between, any of these values as compared to administration of the rizatriptan alone.

Due to the improved bioavailability as described above, the dosage form may contain, or a subject may receive, on a molar basis, less of the rizatriptan or meloxicam than would otherwise be administered of the rizatriptan or meloxicam alone. For example, a dosage form may contain, or a mammal may receive, at least about <NUM> mole% less, at least about <NUM> mole% less, at least about <NUM> mole% less, at least about <NUM> mole% less, at least about <NUM> mole% less, at least about <NUM> mole% less, at least about <NUM> mole% less, at least about <NUM> mole% less, at least about <NUM> mole% less, and/or up to about <NUM> mole% less, <NUM> mole% less, <NUM> mole% less, or any amount in a range bounded by, or between, any of these values of meloxicam as that would otherwise be administered of meloxicam alone.

Use of other NSAIDs, opioids, or other pain medications may be reduced by at least about <NUM>%, at least about <NUM>%, at least about <NUM>%, at least about <NUM>%, at least about <NUM>%, at least about <NUM>%, at least about <NUM>%, at least about <NUM>%, at least about <NUM>%, at least about <NUM>%, at least about <NUM>%, at least about <NUM>%, at least about <NUM>%, or at least about <NUM>%, up to about <NUM>%, or any amount in a range bounded by, or between, any of these values when administered with the invention, as compared to administration of the NSAID, the opioid or the other pain medication alone.

Formation of an inclusion complex may help to improve the properties of a dosage form. For some inclusion complexes, the meloxicam and the SBEβCD may have a molar ratio of about <NUM>-<NUM> (a molar ratio of <NUM> is <NUM> moles of the drug to <NUM> mole of cyclodextrin), about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>, or any ratio in a range bounded by any of these values.

An inclusion complex may be formed by (<NUM>) mixing a homogeneous solution of meloxicam with a homogeneous solution of the SBEβCD to form a homogeneous solution of the meloxicam and the cyclodextrin, and (<NUM>) removing or evaporating the solvent of the homogeneous solution of the meloxicam and the SBEβCD to form the complex comprising the inclusion complex of the meloxicam in a SBEβCD. The solutions can be pH-adjusted aqueous solutions. The pH can be adjusted using a buffering agent. The solvent can be removed or evaporated by lyophilization, spray drying, or any other means that is suitable. The solvent can be removed by vacuum drying, etc..

For some dosage forms, a SBEβCD may be employed in a weight ratio to the meloxicam within the range of about <NUM>-<NUM> (e.g. <NUM> of cyclodextrin per <NUM> of meloxicam is a weight ratio of <NUM>); about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>; about <NUM>-<NUM>; about <NUM>-<NUM>; about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>; about <NUM>-<NUM>; about <NUM>-<NUM>; about <NUM>-<NUM>; about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, or any weight ratio in a range bounded by, or between, any of these values. Each type of cyclodextrin employed may have a different weight ratio to the meloxicam in the dosage form.

For some dosage forms, a SBEβCD may be employed in a weight ratio to rizatriptan within the range of about <NUM>-<NUM> (e.g. <NUM> of SBEβCD per <NUM> of rizatriptan is a weight ratio of <NUM>); about <NUM>-<NUM>; about <NUM>-<NUM>; about <NUM>-<NUM>; about <NUM>-<NUM>; about <NUM>-<NUM>; about <NUM>-<NUM>; about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>; about <NUM>-<NUM>; about <NUM>-<NUM>; about <NUM>-<NUM>; about <NUM>-<NUM>; about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, or any weight ratio in a range bounded by, or between, any of these values. Each type of SBEβCD employed may have a different weight ratio to rizatriptan in the dosage form.

For the amount of rizatriptan, salt forms of rizatriptan may be present in the amounts recited, or amounts that are molar equivalents to these amounts for the rizatriptan free base. For example, assuming that the molecular weight of rizatriptan free base is <NUM>/mol, <NUM> of rizatriptan is <NUM> mmol of rizatriptan. Thus, a molar equivalent of <NUM> of rizatriptan free base would be the mass of <NUM> mmol of that salt form. For example, for the benzoate salt (mw = <NUM>/mol), the molar equivalent of <NUM> of the free base (or <NUM> mmol), would be <NUM>. These doses may be a safe dose for repeated administration, such as <NUM>, <NUM>, <NUM>, or <NUM> times a day, or repeated at an interval of <NUM> days, <NUM> days, <NUM> days, <NUM> days, <NUM> days, <NUM> days, <NUM> days, <NUM> days, <NUM> days, <NUM> days, <NUM> days, <NUM> days, <NUM> days, <NUM> days, <NUM> days, <NUM> days, <NUM> days, <NUM> days, <NUM> days, <NUM> days, <NUM> days, <NUM> days, <NUM> days, <NUM> days, <NUM> days, <NUM> days, <NUM> days, <NUM> days, <NUM> days, <NUM> days, <NUM> weeks, <NUM>-<NUM> weeks, about <NUM>-<NUM> months, about <NUM> weeks, about <NUM>-<NUM> months, about <NUM>-<NUM> months, about <NUM>-<NUM> months, about <NUM>-<NUM> months, about <NUM>-<NUM> months, about <NUM>-<NUM> months, about <NUM>-<NUM> months, about <NUM>-<NUM> months, about <NUM>-<NUM> months, about <NUM>-<NUM> months, etc..

Any reference to Tmax, Cmax, AUC, or any other pharmacokinetic parameter should be understood to include an average, mean, or median value in human beings, such as human patients or human subjects.

Unless otherwise indicated, the AUC refers to the AUC calculated to the last measured concentration (AUC<NUM>-t), over a period of <NUM> hours (AUC<NUM>-<NUM>), or extrapolated to infinity (AUC<NUM>-inf).

For example, a dosage form described herein may reduce the Tmax of meloxicam, such as a median, mean, or average Tmax of meloxicam in human beings. In some embodiments, the dosage form may be used to treat a patient to achieve the Tmax of meloxicam in the patient within about <NUM> minutes; within about <NUM> minutes; within about <NUM> minutes; within about <NUM> minutes; within about <NUM> minutes; within about <NUM> minutes; within about <NUM> minutes; within about <NUM> minutes; within about <NUM> minutes; within about <NUM> minutes; within about <NUM> minutes; within about <NUM> minutes; within about <NUM> minutes; about <NUM>-<NUM> minutes; about <NUM>-<NUM> minutes, about <NUM>-<NUM> minutes, about <NUM>-<NUM> minutes; about <NUM>-<NUM> minutes; about <NUM>-<NUM> minutes; about <NUM>-<NUM> minutes; about <NUM>-<NUM> minutes; about <NUM>-<NUM> minutes; about <NUM>-<NUM> hr; about <NUM>-<NUM> hr; about <NUM>-<NUM> hr; about <NUM>-<NUM> hr; about <NUM>-<NUM> hr; about <NUM>-<NUM> hr; about <NUM>-<NUM> hr; about <NUM>-<NUM> hr; about <NUM>-<NUM> hr; about <NUM>-<NUM> hr; about <NUM>-<NUM> hr; about <NUM>-<NUM> hr; about <NUM>-<NUM> hr; about <NUM>-<NUM> hr; about <NUM>-<NUM> hr; or any Tmax in a range bounded by, or between, any of these values; after administration of the dosage forms described above.

An oral dosage form may have a Tmax of meloxicam, such as a median, mean, or average Tmax of meloxicam in human being, that is shorter than would be achieved by administering meloxicam by intramuscular injection. An oral dosage form may have a Tmax of meloxicam that is shorter, or may increase meloxicam plasma levels at a faster rate, by a factor of at least about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM>, or by a factor of about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, or by a factor in a range bounded by any of these values, as compared to that observed by intramuscular injection.

The dosage form is formulated for oral administration, for example, with an inert diluent or with an edible carrier, or it may be enclosed in hard or soft shell gelatin capsules, compressed into tablets, or incorporated directly with the food of the diet. For oral therapeutic administration, the active compound may be incorporated with an excipient and used in the form of ingestible tablets, buccal tablets, coated tablets, troches, capsules, wafers, , and the like.

Tablets, troches, pills, capsules and the like may also contain one or more of the following: a binder such as gum tragacanth, acacia, corn starch or gelatin; an excipient, such as dicalcium phosphate; a disintegrating agent such as corn starch, potato starch, alginic acid and the like; a lubricant such as magnesium stearate; a sweetening agent such as sucrose, lactose or saccharin; or a flavoring agent such as peppermint, oil of wintergreen or cherry flavoring. When the unit dosage form is a capsule, it may contain, in addition to materials of the above type, a liquid carrier. Various other materials may be present as coating, for instance, tablets, pills, or capsules may be coated with shellac, sugar or both. It may be desirable for material in a dosage form or pharmaceutical composition to be pharmaceutically pure and substantially nontoxic in the amounts employed.

In addition to meloxicam, a SBEβCD, rizatriptan, and a bicarbonate, some dosage forms may contain excipients such as microcrystalline cellulose (e.g. about <NUM>-<NUM>%), starch (e.g. about <NUM>-<NUM>%), fumed silica (e.g. <NUM>-<NUM>%), polyvinylpyrrolidone (e.g. about <NUM>-<NUM>%), and/or magnesium stearate (e.g. about <NUM>-<NUM>%).

The dosage form may further comprise an additional therapeutically active agents, such as an acid inhibitor or an analgesic.

The dosage form may further comprise an acid inhibitor present in an amount effective to raise the gastric pH of a patient to at least <NUM>, to at least <NUM>, to at least <NUM>, to at least <NUM>, to at least <NUM>, and more to at least <NUM>, when one or more unit dosage forms are administered. The term "acid inhibitor" refers to agents that inhibit gastric acid secretion and increase gastric pH. Specific H<NUM> blockers, also referred to as H<NUM> antagonists or histamine H<NUM> blockers or antagonists, which may be used include but are not limited to cimetidine, ranitidine, ebrotidine, pabutidine, lafutidine, loxtidine, famotidine, or combinations thereof.

Other agents that may be effectively used as acid inhibitors are the proton pump inhibitors such as omeprazole, esomeprazole, pantoprazole, lansoprazole, dexlansoprazole, rabeprazole, pariprazole, leminoprazole and tenatoprazole. The daily dose of the acid inhibitor, such as esomeprazole, may be about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>, about <NUM>, about <NUM>, about <NUM> or any other amount in a range bounded by, or between, any of these values.

Examples of particular proton pump inhibitors include esomeprazole, present in unit dosage forms in an amount of between <NUM> and <NUM>; omeprazole, present in unit dosage forms in an amount of between <NUM> and <NUM>; lansoprazole, present in unit dosage forms in an amount of between <NUM> and <NUM> (and preferably at between <NUM> and <NUM>); and pantoprazole, present in unit dosage forms in an amount of between <NUM> and <NUM>. The proton pump inhibitor (such as esomeprazole) may be present in the dosage form in an amount of about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, or about <NUM>-<NUM>. Recently, a newer class of acid inhibitor has been developed which competes with potassium at the acid pump. The compounds in this class have been referred to as "reversible proton pump inhibitors" or "acid pump antagonists" and may also be used. Examples include AZD-<NUM>, AR-H047108, CS-<NUM>, pumaprazole, revaprazan and soraprazan (see <CIT> and <CIT>).

Additional therapeutically active agents may include an analgesic such as a second non-steroidal anti-inflammatory drug, an opioid, a steroid, a triptan, etc. The dosage form or treatment may also further comprise administering a second non-steroidal anti-inflammatory drug in an amount effective to reduce or eliminate pain or inflammation. It will be understood that, for the purposes of the present disclosure, reference to an acid inhibitor, NSAID, or analgesic agent will include all of the common forms of these compounds and, in particular, their pharmaceutically acceptable salts. The amounts of NSAIDs which are therapeutically effective may be lower in the current disclosure than otherwise found in practice due to potential positive kinetic interaction and NSAID absorption in the presence of an acid inhibitor, and or in the presence of a buffering agent.

The dosage form or treatment may further comprise administering an opioid in an amount effective to reduce or eliminate pain or inflammation. The opioid may include, but is not limited to, (dextro)propoxyphene, A-methylfentanyl, alfentanil, allylprodine, bezitramide, buprenorphine, butorphanol, carfentanyl, desmethylprodine, dextromoramide, dezocine, diacetylmorphine, dihydrocodeinone, dihydroetorphine, dimorphone, diphenoxylate, dipipanone, etorphine, fentanyl, ketobemidone, lefetamine, levacetylmethadol, levomethorphan, levorphanol, loperamide, meperidine, meptazinol, methadone, methylmorphine, morphine, nalbuphine, nalmefene, naloxone, naltrexone, nicomorphine, ohmefentanyl, oripavine, oxycodone, oxymorphone, PEPAP, paramorphine, pentazocine, phenazocine, piritramide, prodine, remifentanil, sufentanil, tapentadol, tilidine, tramadol, or combinations thereof.

The term "unit dosage form" as used herein refers to a single entity for drug administration. A "unit dosage form" (or "unit dose form") may also be referred to as a "fixed dosage form" (or "fixed dose form") or "fixed dosage combination" (or "fixed dose combination") and are otherwise interchangeable. The unit dosage form may be a multilayer tablet.

The unit dosage form is suitable for oral administration to a patient. The unit dosage form may be a tablet. The unit dosage form may be a multilayer tablet comprising a single core and one or more layers outside of the core.

Some dosage forms may comprise a first layer comprising meloxicam, an SBEβCD, and a bicarbonate; and a second layer comprising a rizatriptan and a bicarbonate.

The first layer may contain, for example, any amount of meloxicam in one of the ranges recited above. For example, all of the meloxicam in the dosage form may be present in the first layer. The second layer may contain all of rizatriptan, such that any amount in the ranges recited above with respect to the triptan may apply to the second layer.

The first layer may contain about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, or about <NUM> of the bicarbonate, such as sodium bicarbonate, or any amount of the bicarbonate in a range bounded by any of these values.

The second layer may contain about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, about <NUM>-<NUM>, or about <NUM> of the bicarbonate, such as sodium bicarbonate, or any amount of the bicarbonate in a range bounded by any of these values.

Some oral dosage forms may have enteric coatings or film coatings. A dosage form may comprise a tablet or a capsule having an enteric coating. A dosage form may comprise a tablet or a capsule having a film coating.

The effect of varying amounts of potassium carbonate (K<NUM>CO<NUM>) and sodium bicarbonate (NaHCO<NUM>) on the pH of acidic media was tested. The acidic media was chosen to simulate gastric conditions. K<NUM>CO<NUM> or NaHCO<NUM> was added to <NUM> of a <NUM> N HCl solution (pH <NUM>). The pH of the solution was measured after addition of the K<NUM>CO<NUM> or NaHCO3. Deionized water (<NUM>) was then added to the mixture and pH was measured again. The results are shown in Tables <NUM>-<NUM>.

Tablets containing meloxicam and combinations of cyclodextrin, K<NUM>CO3, or NaHCO<NUM> were manufactured and tested for dissolution. Tablets containing meloxicam alone (MOBIC®) were purchased and also tested for dissolution. The tested tablets are listed in Table <NUM>. Meloxicam in the form of meloxicam/cyclodextrin inclusion complexes was used in the tablets containing meloxicam and cyclodextrin. The inclusion complexes were formed by mixing meloxicam and cyclodextrin in an aqueous pH-adjusted solution. The pH of the solution was adjusted using buffering agents. The resulting soluble meloxicam/cyclodextrin inclusion complexes were then spray dried. This spray-dried dispersion was used in the manufacture of the tablets containing cyclodextrin.

Dissolution testing in acidic medium (chosen to simulate gastric conditions) was performed by placing the tablets in a <NUM> N HCl solution, at an agitation rate of <NUM> RPM, and vessel temperature of approximately <NUM>. The results are presented in Tables <NUM> and in <FIG>. Results at various time points (<NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, and <NUM> minutes) are presented as percent (%) of meloxicam dissolved.

Dissolution of meloxicam was greater with the tablets containing various combinations of meloxicam and cyclodextrin, K<NUM>CO<NUM>, or NaHCO<NUM>, as compared to tablets containing meloxicam alone. For example, after <NUM> minutes, dissolution of meloxicam tablets containing NaHCO<NUM> was <NUM>% as compared to <NUM>% for tablets containing meloxicam alone.

Dissolution of meloxicam increases with increasing amounts of K<NUM>CO<NUM> in the absence of cyclodextrin. However, in the presence of cyclodextrin, increasing amounts of K<NUM>CO<NUM> did not appear to increase meloxicam dissolution. At the highest dose of potassium carbonate tested, meloxicam dissolution in the presence of cyclodextrin was reduced by approximately <NUM>% as compared to meloxicam dissolution in the absence of cyclodextrin at <NUM> minutes.

Dissolution of meloxicam with NaHCO<NUM> was significantly greater than that observed with the highest dose of K<NUM>CO<NUM> at <NUM> minutes (<NUM>% versus <NUM>%), and at <NUM> minutes (<NUM>% versus <NUM>%). Meloxicam dissolution in the presence of cyclodextrin was also significantly greater with NaHCO<NUM> as compared to the highest dose of K<NUM>CO<NUM> at <NUM> minutes (<NUM>% versus <NUM>%), and at <NUM> minutes (<NUM>% versus <NUM>%). NaHCO<NUM> in the presence of cyclodextrin increased meloxicam dissolution at <NUM> minutes as compared to potassium bicarbonate which resulted in a reduction in dissolution.

A bilayer tablet containing <NUM>) an inclusion complex of SBEβCD with meloxicam prepared as described in Example <NUM>, and <NUM>) sodium bicarbonate was prepared (SBEβCD-Meloxicam/Bicarbonate). The first layer contained an inclusion complex of <NUM> meloxicam and <NUM> SBEβCD, and <NUM> of sodium bicarbonate. The second layer contained <NUM> of esomeprazole and <NUM> of sodium bicarbonate.

A total of <NUM> human subjects were randomly assigned in a <NUM>:<NUM> ratio to treatment with the SBEβCD-Meloxicam/Bicarbonate tablets described above or Mobic® tablets (<NUM> meloxicam), once daily for <NUM> days under fasting conditions.

On the first day of dosing, plasma samples were collected for concentration analysis of meloxicam at several time points. Concentrations of meloxicam were determined using LC-MS/MS. Pharmacokinetic parameters were calculated. The results are depicted in <FIG>.

The median Tmax for meloxicam, the trial's primary endpoint, was <NUM> times faster for the SBEβCD-Meloxicam/Bicarbonate tablets as compared to Mobic® (<NUM> hour versus <NUM> hours respectively, p<<NUM>).

The SBEβCD-Meloxicam/Bicarbonate tablets also demonstrated higher mean maximum plasma concentration (Cmax) (p=<NUM>), faster time to therapeutic plasma concentration (p<<NUM>), and faster time to half-maximal plasma concentration (p<<NUM>) as compared to Mobic®.

A monolayer tablet containing <NUM>) the inclusion complex of SBEβCD with meloxicam; <NUM>) rizatriptan; and <NUM>) sodium bicarbonate was prepared (SBEβCD-Meloxicam/rizatriptan/Bicarbonate). The monolayer tablet contained <NUM> of meloxicam, <NUM> of rizatriptan, and <NUM> of sodium bicarbonate. The inclusion complex was the same as the inclusion complex of Example <NUM>.

Dissolution testing of the tablets in acidic medium (chosen to simulate gastric conditions) was performed by placing the tablets in a <NUM> N HCl solution, at an agitation rate of <NUM> RPM, and vessel temperature of approximately <NUM>. The results are presented in Tables <NUM>. Results at various time points (<NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, and <NUM> minutes) are presented as percent (%) of meloxicam, and percent (%) of rizatriptan dissolved.

As shown in Table <NUM>, the dissolution results of the tablets in Example <NUM> are very similar to the dissolution result of Example <NUM>. Therefore, we expect the pharmacokinetic properties, including bioavailability, Tmax, etc., of the tablets in Example <NUM> to be similar to those described in Example <NUM> and <FIG>.

Unless otherwise indicated, all numbers expressing quantities of ingredients, properties such as molecular weight, reaction conditions, and so forth used in the specification and claims are to be understood in all instances as indicating both the exact values as shown and as being modified by the term "about. " Accordingly, unless indicated to the contrary, the numerical parameters set forth in the specification and attached claims are approximations that may vary depending upon the desired properties sought to be obtained. At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the scope of the claims, each numerical parameter should at least be construed in light of the number of reported significant digits and by applying ordinary rounding techniques.
