No. 9,572,819, filed May 27, 2016, which claims priority to Indian Patent Application Nos. 2682/CHE/2015, filed May 28, 2015, and 6614/CHE/2015, filed Dec. 10, 2015, the entire disclosures of which are incorporated herein by reference in their entireties.
Non-steroidal anti-inflammatory drugs (NSAID) are generally used for the treatment of acute pain, inflammatory pain, visceral pain, breakthrough pain, nociceptive pain, neuropathic pain, dysmenorrhea, post-surgical pain, acute postpartum pain, postoperative pain management chronic pain in osteoarthritis, rheumatoid arthritis and pain due to other diseases and causes.
Celecoxib is approved in U.S. under brand name CELEBREX®, as oral capsules and used in the treatment of osteoarthritis, rheumatoid arthritis, juvenile rheumatoid arthritis, ankylosing spondylitis, acute pain, chronic pain, primary dysmenorrhea and familial adenomatous polyposis. It is available in the strengths of 50 mg, 100 mg, 200 mg and 400 mg.
Celecoxib was described in U.S. Pat. No. 5,466,823 assigned to Searle, a class of 1, 5-diaryl pyrazoles and their salts together with processes for the preparation of such compounds.
Celecoxib is chemically designated as 4-[5-(4-methylphenyl)-3-(trifluoromethyl)-1H-pyrazol-1-yl] benzenesulfonamide and is a diaryl-substituted pyrazole. The empirical formula is C17H14F3N3O2S, and the molecular weight is 381.38; the chemical structure is as follows:
U.S. Pat. No. 5,466,823 contains general references to formulations for the administration of 1,5-diaryl pyrazoles, including orally deliverable dosage forms such as tablets and capsules.
U.S. Pat. No. 5,760,068 describes a class of 1,5-diaryl pyrazole compounds including celecoxib that are selective inhibitors of cyclooxygenase-2 and can be administered to treat, among other conditions and disorders, pathological conditions associated with rheumatoid arthritis and osteoarthritis.
Celecoxib is a hydrophobic and highly permeable drug belonging to class II of biopharmaceutics classification system. Celecoxib is a neutral molecule that is essentially insoluble in water which leads to high variability in absorption and hence has limited bioavailability after oral administration. It also has pre-systemic metabolism.
Celecoxib has an aqueous solubility of about 5 μg/ml at between 5° C. and 40° C., which is pH independent at pH<9. Celecoxib is not readily dissolved and dispersed for rapid absorption in the gastrointestinal tract when administered orally, for example in capsule form. Oral administration is associated with a delayed onset of the desired pharmacological action. It is known that upon oral administration, celecoxib takes approximately 3.0 hours for peak plasma concentrations to be achieved and hence have delayed onset of action after administration. Additionally, the intake of food further influences drug absorption. However, acute pains, as in the case of migraine pain, surgical pain, trauma, pain due to kidney stones, and arthritis, demand immediate/faster pain relief.
Accordingly, there is a long felt need to develop a composition for celecoxib or its pharmaceutical salts thereof, which can be readily dissolved/dispersed for rapid absorption in the gastrointestinal tract in order to provide faster pain relief

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art.
As used herein, “comprising” is “open ended” and means the elements recited, or their equivalent in structure or function, plus any other element or elements which are not recited. The terms “having” and “including” are also to be construed as open ended unless the context suggests otherwise. All the ranges recited herein include the endpoints, including those that recite a range “between” two values.
The terms “a” and “the” as used herein are understood to encompass the plural as well as the singular or otherwise clearly mentioned wherever needed. For example, reference to “an excipient” includes reference to one or more of such excipients, and reference to “the carrier” includes reference to one or more of such carriers.
The terms such as ‘about’, ‘up to’, ‘generally’, ‘substantially’ and the like are to be construed as modifying a term or value such that it is not an absolute. Such terms will be defined by the circumstances and the terms that they modify as those terms are understood by those of skilled in the art. This includes, at very least, the degree of expected experimental error, technical error and instrumental error for a given experiment, technique or an instrument used to measure a value. The term “about” is used to provide flexibility to a numerical range endpoint by providing that a given value may be “a little above” or “a little below” the endpoint. As used herein, the term “about” means a slight variation of the value specified, preferably within 10% of the value specified. Nevertheless, the term “about” can mean a higher tolerance of variation depending on for instance the experimental technique used. Said variations of a specified value are understood by the skilled person and are within the context of the present invention. As an illustration, a numerical range of “about 1 to about 5” should be interpreted to include not only the explicitly recited values of about 1 to about 5, but also include individual values and sub-ranges within the indicated range. Thus, included in this numerical range are individual values such as 2, 3, and 4 and sub-ranges such as from 1-3, from 2-4, and from 3-5, etc., as well as 1, 2, 3, 4, 5, or 6, individually. This same principle applies to ranges reciting only one numerical value as a minimum or a maximum.
As used herein, “free of” or “essentially free of” a particular compound or compositions or excipients refer to the absence of any separately added portion of the referenced compound or composition or excipients. The term “free of” or “essentially free of” means that there is less than 1% w/w of a particular compound or compositions, or excipients, wherein the amount present does not impart any functional value to the composition.
“Celecoxib” as used herein encompasses base form as well as its pharmaceutically acceptable salts, complexes, polymorphs, hydrates, solvates, enantiomers or racemates. The solid state form of celecoxib used in the composition of the present application is not critical. For example, celecoxib can be amorphous or crystalline.
The term “pharmaceutically acceptable salts” as used herein includes those salts which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of humans and lower animals without undue toxicity, irritation, allergic response and the like, which are well known in the art. The salts can be prepared in situ during the final isolation and purification of the compounds of the invention, or separately by reacting the pharmaceutically active substance, having a freebase function, with a suitable organic acid or inorganic acid.
As used herein, an “effective amount” or a “therapeutically effective amount” of a drug refers to a non-toxic, but sufficient amount of the drug, to achieve therapeutic results in treating a condition for which the drug is known to be effective. In this instance, an effective amount is an amount of celecoxib which is sufficient to treat pain in a patient in need thereof which is to say to provide some measure of analgesia to reduce at least the patient's perception of pain.
The term “liquid composition” refers to a liquid composition that is ingested with or without further mixing with aqueous or suitable media before oral administration.
The term “stable composition(s)” as used herein, refers to a composition that does not show any precipitation in Fasted-State Simulated Gastric Fluid (FaSSGF) at pH 2.0, temperature of 37° C.±0.5° C. and under stirring at a speed of 50 rpm at least for 60 minutes.

The compositions comprising celecoxib were prepared as given in Table 1.
Manufacturing Procedure:
Celecoxib was added to solubilisers (lauroyl macrogolglycerides, polyoxy 35 castor oil and PEG-40 Hydrogenated Castor Oil) and mixed properly to obtain uniform mixture.
Further to mixture of step 1 medium chain glycerides (caprylic/capric triglyceride and glyceryl caprylate) were added.
To the mixture of step 2, other ingredients such as flavours and sweeteners were added and mixed well.
To the composition of step 3, propylene glycol was added and mixed thoroughly with slight heating 30° C.±5° C. until a uniform dispersion is obtained and cool the solution to 25-30° C. under stirring.
To the composition of step 4, purified water was added and mixed well until a clear solution obtained.
The composition of step 5 was filled in amber colored glass bottle with 18 mm child resistant—tamper evident cap.
Compositions of Examples 1, 2 & 3 were evaluated for onset of precipitation time.
2 ml of compositions comprising 100 mg of celecoxib were dropped in 250 mL of FaSSGF, pH 2.0, at 37° C. under stirring and onset of precipitation was noted.
Celecoxib dissolution study of 2 ml of the compositions of Examples 1, 2 & 3 comprising 100 mg of celecoxib was performed in a standard USP dissolution medium under the following conditions: USP apparatus II paddles; dissolution medium (900 ml 0.01N HCl containing 0.5% sodium lauryl sulfate) at a speed of 50 rpm and a temperature of 37° C.
The composition of Example 3 was found to be stable after subjecting it to stability evaluation conditions of 25° C./60% RH and 40° C./75% RH. The composition was also evaluated for viscosity, density, pH, oil droplet size.
A four-way, randomized, crossover study to compare the bioavailability of Example 3 (Celecoxib Oral Solution) at doses of 120 mg, 180 mg and 240 mg versus CELEBREX® (celecoxib) 400 mg capsules and to determine dose-proportionality of Example 3 formulations in healthy volunteers under fasting conditions.
In each study period, a single dose of celecoxib composition was administered orally, in the morning, following a 10-hour overnight fast. The administration is done as follows:
Celecoxib plasma concentrations and other pharmacokinetic parameters were determined. Observed pharmacokinetic parameters are given in Table 5.

A three-way, double blind, randomized, crossover study was designed to compare the bioavailability of Example 3 (Celecoxib Oral Solution) at doses of 120 mg and 240 mg versus placebo and to determine efficacy of the stable oral composition in Example 3 in treating migraine. 60 subjects with history of 2-6 episodic migraine were recruited into the study in 6 sites.
In each study period, a single dose of the stable oral composition was administered orally, in the morning, following a 10-hour overnight fast. The administration is done as follows:
PK samples were collected at home (if feasible for subjects who consented) at 0.5 hr and 2 hr post dosing during actual migraine attack.
In at least some of the previously described embodiments, one or more elements used in an embodiment can interchangeably be used in another embodiment unless such a replacement is not technically feasible. It will be appreciated by those skilled in the art that various other omissions, additions and modifications may be made to the methods and structures described above without departing from the scope of the claimed subject matter. All such modifications and changes are intended to fall within the scope of the subject matter, as defined by the appended claims.
With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.
It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to embodiments containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”
In addition, where features or aspects of the disclosure are described in terms of Markush groups, those skilled in the art will recognize that the disclosure is also thereby described in terms of any individual member or subgroup of members of the Markush group.
As will be understood by one of skill in the art, for any and all purposes, such as in terms of providing a written description, all ranges disclosed herein also encompass any and all possible sub-ranges and combinations of sub-ranges thereof. Any listed range can be easily recognized as sufficiently describing and enabling the same range being broken down into at least equal halves, thirds, quarters, fifths, tenths, etc. As a non-limiting example, each range discussed herein can be readily broken down into a lower third, middle third and upper third, etc. As will also be understood by one skilled in the art all language such as “up to,” “at least,” “greater than,” “less than,” and the like include the number recited and refer to ranges which can be subsequently broken down into sub-ranges as discussed above. Finally, as will be understood by one skilled in the art, a range includes each individual member. Thus, for example, a group having 1-3 articles refers to groups having 1, 2, or 3 articles. Similarly, a group having 1-5 articles refers to groups having 1, 2, 3, 4, or 5 articles, and so forth.
