COMPOSITIONS AND METHODS FOR THE
TREATMENT OF .HYPERGLYCEMIA
PRIORITY
10001] The present application claims the benefit of Indian Provisional Patent Application. No. 181 IICHEI2012 filed on 08-May-2012, the entire disclosure of which is relied on for all purposes and is incorporated into this application by reference.
HELD OF THE INVENTION
100021 This disclosure generally relates to compounds and. compositions for the treatment.
of hyperglycemia, diabetes and insulin resistance. More particularly, this invention relates to treating subjects with a pharmaceutically acceptable dose of compounds, crystals, esters, stereoisomersõ enamiomers, salts, hydrates, prodrug,s, or mixtures thereof BACKGROUND OF THE INVENTION
100031 The multifaceted metabolic syndrome is defined as a number of major metabolic disorders that enhances the risk of cardiovascular disease (CVD) ¨ still the most important cause of death in the Western world ----- and type 2 diabetes mellitus. It is also known as the insulin resistance syndrome, syndrome X, dysmetabolic syndrome, or the deadly quartet, and is characterized by aberrations in a wide variety of metabolic risk.
markers such as hyperinsuline.mia, impaired glucose metabolism, elevated plasma levels of triglycerides, decreased levels of high-density lipoprotein cholesterol (l'IDI,C), raised blood pressure, centrally distributed obesityõ impaired endothelial and haemostatic function, and a low-grade inflammatoly state.
(00041 Type 2 Diabetes Mellitus (T2DM) is characterized by fasting and postprandial hyperglycemia and relative insulin insufficiency. If left untreated, then hyperglycemia may cause long term microvascular and .macrovaseular complications, such as nephropathy, neuropathy, retinopathy, and atherosclerosis. This disease causes significant

2 .morbidity and mortality at considerable expense to patients, their families and society.
The incidence of T2DM worldwide is now increasing at. more rapid rates in Africa, .Asia and South America than in Europe or the U.S, Thus, T2DM is now considered worldwide epidemic.
100051 Oxidative stress has long been associated with the late complications of diabetes, and has been implicated in their etiology. The reactive oxygen intermediates, produced in mitochondria, peroxisomes, and the cytosol, are scavenged by cellular defending systems, including enzymatic (ex. superoxide dismutase, glutathione peroxidase (IPx, glutathione.
reductase and catalase) and nonenzy Matic antioxidants (ex. glutathione thioredoxin, lipoic acid, ubiquinol, albumin, uric acid, flavonoids, vitamins A, C and E.
etc.). Some are located in cell membranes, others in the cytosol, and others in the blood plasma, in hyperglycemia, an altered oxidative metabolism is a consequence either of the chronic exposure to hyperglycaemia or of the absolute or relative insulin deficit; insulin regulates several reactions involved in ox i do-red u ct v e metabolism.
Despite strong experimental evidence indicating that oxidative stress may determine the onset and progression of late-diabetic complications controversy exists about whether the increased oxidative stress is merely associative rather than causal in hyperglycemia.
[00061 Managing acute pathology of often relies on the addressing underlying pathology and symptoms of the disease. There is currently a need in the art for new compositions to treatment or delay of the onset of diabetes related hyperglycemia and its associated.
complications progression _SUMMARY OF THE INVENTION

1001.7] Compounds that have the same molecular formula but differ in the nature or sequence of bonding of their atoms or the arrangement of their atoms in space are termed "isomers." 'Isomers that differ in the arrangement of their atoms in space are termed "stereoisome.rs." Diastereomers are stereoisomers with opposite configuration at one or more chiral centers which are .not enantiomers. .Stereoisomers bearing one or more asymmetric centers that are non- superimposable mirror images of each other are termed "enantiomers." When a compound has an asymmetric center, for example, if a carbon atom is bonded to four different groups, a pair of enantiomers is possible. An enamiomer can be characterized by the absolute configuration of its asymmetric center or centers and.
is described by the R.- and S-sequencing rules of Cahn, lngold and Prelog, or by the manner in which the molecule rotates the plane of polarized light, and designated. as dextrorotatoly or levorotatory (i.e., as (+) or (-)isomers respectively). A
chiral compound can exist as either individual enantiomer or as a mixture thereof A mixture containing.
equal proportions of the enantiomers ig called a "racetnie mixture".

100251 The term "prodrug" is intended to encompass compounds that, under physiological conditions, are converted into the therapeutically active agents of the present invention. A common method for making a prodnag is to include selected Moieties that are hydrolyzed under physiological conditions to reveal the desired molecule. In other embodiments, the prodrug is converted by an enzymatic activity of the host animal.
100261 The term "prophylactic or therapeutic" treatment is art-recognized and includes administration to the host of one or more of the subject compositions. If it is administered prior to clinical manifestation of the unwanted condition (e.g., disease or other unwanted state of the host animal) then the treatment is prophylactic, i.e.., it protects the host against developing the unwanted condition, whereas if it is administered after manifestation of the unwanted condition, the treatment is therapeutic. (i.e., it is intended to diminish, ameliorate, or stabilize the existing unwanted conthtion or side effects thereof).
100271 The term "predicting" as used herein refers to assessing the probability related diseases patient will sufTe.r from abnormalities or complication andlor terminal platelet aggregation or failure and/or death (i.e. mortality) within a defined time window (predictive window) in the future. The mortality may be caused by the central nervous system or complication. The predictive window is an interval in which the subject will develop one or more of the said complications according to the predicted probability. The predictive window may be the entire remaining lifespan of the subject upon analysis by the method of the present invention, 100281 The term "treating" is art -recognized and includes preventing a disease, disorder or condition from occurring in an animal which may be predisposed to the disease, disorder and/or condition but has not yet been diagnosed as having it;
inhibiting the disease, disorder or condition, e.g., impeding its progress: and relieving the disease, disorder, or condition, e.g., causing regression of the disease, disorder and/or condition, 'Treating the disease or condition includes ameliorating at least one symptom of the particular disease or condition, even if the underlying pathophysiology is not affected., such as treating the hyperglycemia, insulin resistance, diabetes mellitus, diabetes insipidus, type I diabetes, type 2 diabetes, microvascular complications, macrovascular complications, lipid, disorders, hypertriglyceridemi a, cardiovascular complications, and post prandial hyperglycemia of a subject by administration of an agent even though such agent does not treat the cause of the condition. The term "treating", "treat"
or "treatment"
as used herein includes curative, preventative (e.g., prophylactic), adjunct and palliative treatment.

100291 The phrase "therapeutically effective amount" is an art-recognized ternr in certain embodiments, the term refers to an amount of a salt or composition disclosed herein that produces some desired effect at a reasonable benefithisk ratio applicable to any medical treatment. In certain embodiments, the term refers to that amount necessary or sufficient to eliminate or reduce medical symptoms for a period of time, The effective amount may vary depending on such factors as the disease or condition being treated, the.
particular targeted constructs being administered, the size of the subject, or the severity of the disease or condition. One of ordinary skill in the art may empirically determine the effective amount of a particular composition without necessitating undue experimentation.
100301 In certain embodiments, the pharmaceutical compositions described herein are formulated in a manner such that said compositions will be delivered to a patient in a therapeutically effective amount, as part of a prophylactic or therapeutic treatment. The desired amount of the composition to be administered to a patient will depend on absorption, inactivation, and excretion rates of the drug as well as the delivery rate of the salts and compositions from the subject compositions, it is to be noted that dosage values may also vary with the severity of the condition to be alleviated, it is to be further understood that for any particular subject, specific dosage regimens should be adjusted over time according to the individual need and the professional judgment of the person.
administering or supervising the administration of the compositions.
Typically, dosing will be determined using techniques known to one skilled in the art.
[00311 Additionally, the optimal concentration and/or quantities or amounts of any particular salt or composition may be adjusted to accommodate variations in the treatment parameters, Such treatment parameters include the clinical use to which the preparation is put, e.g.:, the site treated, the type of patient, e.g.:, human or non-human, adult or child, and the nature of the disease or condition.

[00321 In certain embodiments, the dosage of the subject compositions provided herein may be determined by reference to the plasma concentrations of the therapeutic composition or other encapsulated materials. For example, the maximum plasma concentration (Cmax) and the area under the plasma concentration-time curve from time 0 to infinity may be used.
10033" When used with respect to a pharmaceutical composition or other material, the term "sustained release" is art-recognized. For example., a subject composition which releases a substance over time may exhibit sustained release characteristics, in contrast to a bolus type administration }Ti which the entire amount of the substance is made.
biologically available at one time. For example, in particular embodiments, upon contact.
with body fluids including blood, spinal fluid, mucus secretions, lymph or the like, one or more of the pharmaceutically acceptable excipients may undergo gradual or delayed.
degradation (e.g., through hydrolysis) with concomitant release of any material incorporated therein, e.g., an therapeutic and/or biologically active salt and/or composition, for a sustained or extended period (as compared to the release from a bolus). This release may result in prolonged delivery of therapeutically effective amounts of any of the therapeutic agents disclosed herein.
190341 The phrases "systemic administration," "administered systen-nically,"
"peripheral administration" and "administered peripherally" are art-recognized, and include the administration of a subject composition, therapeutic o.r other material at a site remote from the disease being treated. Administratioi of an agent for the disease being treated, even if the agent is subsequently distributed systemically, may be termed "local' or "topical" or "regional" administration, other than directly into the central nervous system, e.g., by subcutaneous administration, such that it enters the patient's system and, thus, is subject to metabolism and other like processes.
[00351 The phrase "therapeutically effective amount" is an art-recognized term.. .In certain .embodiments, .the term refers to an amount of a salt Or composition disclosed herein that produces some desired effect at a reasonable benefit/risk ratio applicable to any medical treatment, in certain embodiments, the term refers to that amount necessary or sufficient to eliminate or reduce medical symptoms for a period of time.
The effective amount may- vary depending on such factors as the disease or condition being treated, the particular .targeted constructs being administered, the size of the subject, or the severity of the disease or condition. One of ordinary skill in the art may empirically determine the.
effective amount of a particular composition without necessitating undue experimentation.

The pharmaceutical composition may be also tbrinulated for oral administration, oral solution, injection, subdermal administration, or transdermal administration. The pharmaceutical composition may further comprise at least one of a pharmaceutically acceptable stabilizer, diluent, surfactant, filler, binder, and lubricant.
100381 In many embodiments, the pharmaceutical compositions described herein will incorporate the disclosed compounds and. compositions (Formula 1) to be delivered in an amount sufficient to deliver to a patient a therapeutically effective amount of a compound of formula 1 or composition as part of a prophylactic or therapeutic treatment. The desired concentration of formula I or its pharmaceutical acceptable salts will depend on absorption, inactivation, and excretion rates of the drug as well as the delivery rate of the salts and compositions .f10111 the subject compositions, h is to be noted that dosage values may also vary with the severity of the condition to be alleviated. It is to be further understood that for any particular subject, specific dosage regimens should be adjusted over time according to the individual need and the professional judgment of the person.

administering or supervising the administration of the compositions.
Typically, dosing will be determined using techniques known to one skilled in the art.
10039] .Additionallyõ .the optimal concentration and/or quantities or amounts of any particular compound of formula 1 may be adjusted to accommodate variations in the treatment parameters. Such treatment parameters include the clinical use to which the preparation is put, es., the site treated, the type of patient, es.õ human or non-human, adult or child, and the nature of the disease or condition.
100401 The concentration and/or amount of any compound of formula I may be readily identified by routine screening in animals, e.g., rats, by screening a range of concentration and/or amounts of the .material in question using appropriate assays.
Known methods are also available to assay local tissue concentrations, diffusion rates of the salts or compositions, and local blood flow before. and after administration of therapeutic formulations disclosed herein. One such method is microdialyMs, as reviewed by T. E. Robinson et at. 1991, microdialysis in the neuroscience.s, Techniques, volume 7, Chapter I. The methods reviewed by :Robinson may be applied, in brief, ag foilows. A microdialysis loop is placed in situ in a test animal, Dialysis fluid is pumped through the loop, When compounds with ,formula 1 such as those disclosed herein are injected adjacent to the loop, released drugs are collected in the dialysate in proportion to their local tissue concentrations. The progress of diffusion of the salts or compositions may be determined thereby with suitable calibration procedures using known concentrations of salts or compositions.
[00411 hi certain embodiments, the dosage of the subject compounds of formula provided herein may be determined by reference to the pla,sma concentrations of the therapeutic composition or other encapsulated materials. For example, the maximum plasma concentration (Cmax) and the area under the plasma concentration-time curve from time 0 to infinity may be used.

100421 Generally, in carrying out the methods detailed in this application, an effective dosage for the compounds of Formulas I is in the range of about 0.01 niglk.gldity to about.
100 .mg/kg/day in single or divided doses, for instance 0,01 mg/kg/day to about 50 m.g/kg/day in single or divided doses. The compounds of Formulas I may be administered at a dose of, for example, less than 0.2 mg/kg/day, 0,5 mg/kg/day, 1.0 mgikg/day, 5 mg/kg/day, 10 mg/kg/day, 20 mg/kg/day, 30 mg/kg/day, or 40 mg/kg/day Compounds of Formula. I may also be administered to a human patient at a dose of, for example.
between 0.1 mg and 1000 mg, between 5 mg and 80 mg, or less than 1.0, 9.0, 12.0, 20.0, 50.0, 75,0, 100, 300, 400, 500, 800, 1000, 2000,, 5000 mg per day. in certain embodiments, the compositions herein are administered at an amount that is less than 95%, 90%, 80%, 70%, 60%, 50%, 40%, 30%, 20%, or 10% of the compound of formula I required for the same therapeutic benefit., 100431 An effective amount of the compounds of formula 1 described herein refers to the amount of one of said salts or compositions which is capable of inhibiting or preventing a disease.
100441 An effective amount may be sufficient to prohibit, treat, alleviate, ameliorate, halt, restrain, slow or reverse the progression, or reduce the severity of a complication resulting from nerve damage or demyelization and/or elevated reactive oxidative-nitrosative species and/or abnormalities in physiological homeostasis's, in patients who are at risk for such complications. As such, these methods include both medical therapeutic (acute) and/or prophylactic (prevention) administration as appropriate.. The amount and timing of compositions administered will, of course, be dependent on the.
subject being treated, on the severity of the affliction., on the manner of administration and on the judgment of the prescribing physician. Thus, because of patient-to-patient variability, the dosages given above are a guideline and the physician may ti trate doses of the drug to achieve the treatment that the physician considers appropriate for the patient, In considering the degree of treatment desired, the physician must balance a variety of factors such as age of the patient, presence of preexisting disease, as well as presence of other diseases.
100451 The compositions provided by this application may be administered to a subject.
in need of treatment by a variety of conventional routes of administration, including orally, topically, parenterally, e.g.õ intravenously, subcutaneously or intramedullary.
Further, the compositions may be administered intranasallyõ as a rectal suppository, or using a "flash" formuiation, i.e., allowing the medication to dissolve in the mouth without the need to use water, Furthermore, the compositions may be administered to a subject in need of treatment by controlled release dosage forms, site specific. drug delivery, transderm.al drug del iveryõ patch (active/passive) mediated drug delivery, by stereota.ctic injection, or in nanoparticles, 100461 The compositions may be administered alone or in combination with pharmaceutically acceptable carriers, vehicles or diluents, in either single or multiple doses. Suitable pharmaceutical carriers, vehicles and diluents include inert solid diluents or fillers, sterile aqueous solutions and various organic solvents. The pharmaceutical compositions formed by combining the compositions and. the pharmaceutically acceptable carriers, vehicles or diluents are then readily administered in a variety of dosage forms such as tablets, powders, lozenges, syrups, injectable solutions and the like.
These pharmaceutical compositions can, if desired, contain additional ingredients such as flavotings, binders, excipients and the like. Thus, for purposes of oral administration, tablets containing various excipients such as L-arginine, sodium citrate, calcium carbonate and calcium phosphate may be employed along with various disintegrates such as starch, alginic acid and certain complex silicates, together with binding agents such as polyvinylpyrrolidone, sucrose, gelatin and acacia. Additionally, lubricafing agents such as magnesium stearate, sodium lauryl sulfate and talc are often useful for tabletting purposes. Solid compositions of a similar .type may also be employed as tillers in soft and hard filled gelatin capsules, Appropriate materials for this include lactose or milk sugar and high molecular weight polyethylene glycols. When aqueous suspensions or elixirs. are.

desired for oral administration, the essential active ingredient therein may be combined with various sweetening or flavoring agents, coloring matter or dyes and, if desired, emulsifying or suspending agents, together With diluents such as water, ethanol, propylene glycol, glycerin and combinations thereof. The compounds of formula I may also comprise enterically coated comprising of various excipients, as is well known in the pharmaceutical art.
100471 For parenteral administration, solutions of the compositions may be prepared in (for example) sesame or peanut oil, aqueous propylene glycol, or in sterile aqueous solutions may be employed. Such aqueous solutions should be suitably buffered if necessary and the liquid diluent first rendered isotonic with sufficient saline or glucose.
These particular aqueous solutions are especially suitable for intravenous, intramuscular, subcutaneous and intraperitoneal administration. in this connection, the sterile aqueous media employed. are all readily available by standard techniques known to those skilled in the art.
100481 The formulations, for instance tablets, may contain e.g.. 10 to 100, 50 to 250, 150 to 500 mg, or 350 to 800 mg e.g. 10, 50, 100, 300, 500, 700, 800 mg of the compounds of formula I disclosed herein, for instance, compounds of formula 1 or pharmaceutical acceptable salts of a compounds of Formula.!.
100491 Generally, a composition as described herein may he administered orally, or parenterally (e.g., intravenous, intramuscular, subcutaneous or intramedullary). Topical administration may also be indicated, for example, where the patient is suffering from gastrointestinal disorder that prevent oral administration, or whenever the medication is best applied to .the surface of a. tissue or organ as determined by the attending physician.
Localized administration may also be indicated, .for example, when a high dose is desired at the target tissue or organ. For buccal administration the active composition may take the form of tablets or lozenges formulated in a. conventional manner.

100501 The dosage administered will be dependent upon the identity of the metabolic disease; the type of host involved, including its age, health and weight; the kind, of concurrent. treatment, if any; the frequency of treatment and -therapeutic ratio.

10060j In. one embodiment, the immediate release coating has an average thickness of at least 50 microns, such as from about 50 microns to about 2500 .microns; e.g., from about 250 microns to about 1000 microns, In embodiment, the immediate release coating is typically compressed at a density of more than about 0.9 gicc, as measured by the weight and volume of that specific layer, [00611 in one embodiment, the immediate release coating contains a first portion and a second portion., wherein at least one of the portions contains the second pharmaceutically active agent. In one embodiment, the portions contact each other at a center axis of the tablet. In one embodiment, the first portion includes the first phanna,ceutically active agent and the second portion includes the second pharmaceutically active agent 100621 In one embodiment, .the .first portion contains the first pharmaceutically active agent and the second portion contains the second pharmaceutically active agent, In one embodiment, one of the portions contains a third pharmaceutically active agent. In one embodiment one of the portions contains a second immediate release portion of the same pharmaceuticallv active agent as that contained in the tablet core, 100631 In one embodiment, the outer coating portion is prepared as a dry blend of materials prior to addition to the coated tablet core. In another embodiment the outer coating portion is included of a dried granulation including, the ph art/I
aceutically active agent, 100641 Formulations with different drug release mechanisms described above could be.
combined in a final dosage form containing single or multiple units. :Examples of MUI ti.ple units include MUlti layer .tablets, capsules containing tablets, beads, or granules in a solid or liquid form. Typical, immediate release formulations include compressed tablets, ,4e1s, films, coatings, liquids and particles that can be encapsulated, for example, in a gelatin capsule. :Many methods tbr preparing coatings., covering or incorporating drugs, are known in the art.
100651 The immediate release dosage, unit of the dosage form, i.e., a tablet, a plurality of drug-containing beads, granules or particles., or an outer layer of a coated core dosage, form, contains a therapeutically effective quantity of the active agent with conventional pharmaceutical excipieats. The immediate release dosage unit may or may not be coated, and may or may not be admixed with the delayed. release dosage U1-fit or units (as in an encapsulated mixture of immediate rel.ease ddig-containing granules, particles or beads and delayed release drug-containing granules or beads).
100661 Extended release formulations are generally prepared as diffusion or osmotic systems, for example, as described in "Re.mington¨The Science and Practice of Ph arm a.cy ", 20th. Ed . õ Lippincott Williams & Wilkins, B all i in ore, Md.,. 2000). A
diffusion system typically consists of' one of two types of devices, reservoir and matrix, which are wellknown and described in die art. The matrix devices are generally prepared by compressing the drug with a .slowly dissolving polymer carder into a tablet form.

[00671 .An immediate release portion can be added to the extended release system by means of either applying an immediate release layer on top of the extended release core;
using coating or compression processes or in a multiple unit system such as a capsule containing extended and immediate release beads, [00681 Delayed release dosage formulations are created by coating a solid dosage form with a film of a polymer which is insoluble in the acid environment of the stomach, but soluble in the neutral environment of small intestines. The delayed release dosage units.
can be prepared, for example, by coating a drug or a drug-containing composition with a selected coating material. The drug-containing composition may be a tablet for incorporation into a capsule, a tablet for use as an inner core in a "coated core" dosage form, or a plurality of drug-containing beads, particles or granules, for incorporation into either a tablet or capsule.
10069" A pulsed release dosage form is one that mimics a multiple dosing profile without repeated dosing and typically allows at least a twofold reduction in dosing frequency as compared to the dnig presented as a conventional dosage form (e.g., as a solution or prompt drug-releasing, conventional solid dosage form). A pulsed release profile is characterized by a. time period of no release (lag time) or reduced release followed by rapid drug release, 10070] Each dosage form contains a therapeutically effective amount. of active agent. in one embodiment of dosage forms that mimic a twice daily closing profile, approximately 30 Wt. % to 70 wt. %, preferably 40 wt. % to 60 wt. %, of the total amount of active agent in the dosage form is released in. the initial pulse, and, correspondingly approximately 70 wt. % to 3.0 wt. %, preferably 60 Wi t,''() to 40 wt. %, of the total amount of active agent in the dosag.e form is released in the second pulse. For dosage forms mimicking the twice.
daily dosing profile, the second pulse is preferably released approximately 3 hours to less than 14 hours, and more preferably approximately 5 hours to 12 hours, following admi ni strati on.

100711 Another dosage form contains a compressed tablet or a capsule having a drug containing immediate release dosage unit, a delayed release dosage unit and an optional second delayed release dosage unit, In this dosage form, the immediate release dosage unit contains a plurality of beads, granules particles that release drug substantially immediately following oral administration to provide an initial dose. The delayed release dosage unit contains a plurality of coated beads or granules, which release drug, approximately 3 hours to 14 hours followim,t oral administration to provide a second dose.
1007211 For purposes of tran sdermal, (e,g., .topical) administration, dilute sterile, aqueous or partially aqueous solutions (usually in about 0.1% to 5% concentration), otherwise, similar to the above parenteral solutions, may be prepared, 100731 .Methods of preparing various pharmaceutical compositions with a certain.

100841 Methods of delivering a composition or compositions via a transderm.al patch are known in the art. Exemplary patches and methods of patch delivery are described in US
Patent Nos. 6,974,588, 6,564,093, 6,312,716, 6,440,454, 6,267,983, 6,239,180, and 6,103,275, [00851 Itn another embodiment, a transdermal, patch may comprise: a substrate sheet comprising a composite film formed of a resin composition comprising 100 parts by weight. of a polyvinyl chloride-polyurethane composite and 2-10 parts by weight of a styrene-ethylene-butylene-styrene copolymer, a first adhesive layer on the one side of the composite film, and a. polyalkylene terephthalate film adhered to the one side of the.
composite film by means of the first adhesive layer, a primer layer which comprises a.
saturated polyester resin and is formed on the surface of the polyalkyl:ene .terephthalate film; and a second adhesive layer comprising a styrene-diene-.styrene block copolymer containing a pharmaceutical agent layered on the primer layer. A method for the:
manufacture of the above-mentioned substrate sheet comprises preparing the above resin composition molding the resin composition into a composite film by a calendar process, and then adhering, a polyalkylene terephthalate film on one side of the composite film by means of an adhesive layer thereby forming the substrate sheet, and forming a.
primer layer comprising a saturated polyester resin on the outer surface of the polyalkylene terephthal ate film, 10086" Another type of patch comprises incorporating the drug directly in a.
pharmaceutically acceptable adhesive and laminating the drug-containing adhesive onto a suitable backing member, e.g. a polyester backing membrane. The drug should be present:
at a concentration which will not affect the adhesive properties, and at the same time deliver the required clinical dose.
10087" Transdemal patches may be passive or active: Passive transdermal drug delivery systems currently available, such as the nicotine, estrogen and nitroglycerine patches, deliver small-molecule drugs. Many of the newly developed proteins and peptide drugs are too large to be delivered through passive transdermal patches and may be delivered using technology such as electrical assist (iontophoresis) for large-molecule drugs.
00881 lontophoresis is a technique employed for enhancing the flux of ionized substances through membranes by application of electric current. One example of an iontophoretic membrane is given in U.S. Pat. No. 5,080,646 to Theeuwe.s. The principal mechanisms by which iontophoresis enhances molecular transport across the skin are (a) repelling a charged ion from an electrode of the same charge, (b) electroosmosis, the convective movement of solvent that occurs through a charged pore in response the.
preferential passage of counter-ions when an electric field is applied or (c) increase skin permeability due to application of electrical current.
10089" In some Cases, it may be desirable to administer in the t7orm of a kit, it may.
comprise a container for containing the separate compositions such as a.
divided bottle or a divided foil packet. Typically the kit comprises directions for the administration of the separate components. The kit .tbrin is particularly advantageous when the separate components are preferably administered in different dosage forms (e.g., oral and parenteral), are administered at different dosage intervals, or when titration of the individual components of the combination is desired by the prescribing physician.
[00901 An example of such a kit is a so-called blister pack. Blister packs are well known in the packaging industry and are widely used for the packaging of pharmaceutical unit:
dosage forms (tablets, capsules, and the like). Blister packs generally consist of a sheet of relatively stiff material covered with a foil of a plastic material that may be transparent.
