Abstract

The invention provides a method of sustained delivery of a lactam, imide, amide, sulfonamide, carbamate or urea containing parent drug by administering to a patient an effective amount of a prodrug compound of the invention wherein upon administration to the patient, release of the parent drug from the prodrug is sustained release. Prodrug compounds suitable for use in the methods of the invention are labile conjugates of parent drugs that are derivatized through carbonyl linked prodrug moieties. The prodrug compounds of the invention can be used to treat any condition for which the lactam, imide, amide, sulfonamide, carbamate or urea containing parent drug is useful as a treatment.

Description

PRODRUGS OF NH-ACIDIC COMPOUNDS: ESTER, CARBONATE, CARBAMATE
AND PHOSPHONATE DERIVATIVES
BACKGROUND OF THE INVENTION
(i) Field of the Invention.
The present invention relates to prodrugs of lactam, amide, imide, sulfonamide, carbamate, urea, benzamide, and acylaniline containing pharmacophores.
(ii) Background of the Invention.
Drug delivery systems are often critical for the safe and effective administration of a biologically active agent. Perhaps the importance of these systems is best realized when patient compliance and consistent dosing are taken under consideration. For instance, reducing the dosing requirement for a drug from four-times-a-day to a single dose per day would have significant value in terms of ensuring patient compliance and optimizing therapy.
Optimization of a drug's bioavailability has many potential benefits. For patient convenience and enhanced compliance it is generally recognized that less frequent dosing is desirable. By extending the period through which the drug is released, a longer duration of action per dose is expected. This will then lead to an overall improvement of dosing parameters such as taking a drug once a day where it has previously required four doses per day or dosing once a week or even less frequently when daily dosing was previously required. Many drugs are presently dosed once per day, but not all of these drugs have pharmacokinetic properties that are suitable for dosing intervals of exactly twenty-four hours.
Extending the period through which these drugs are released would also be beneficial.
One of the fundamental considerations in drug therapy involves the relationship between blood levels and therapeutic activity. For most drugs, it is of primary importance that serum levels remain between a minimally effective concentration and a potentially toxic level. In pharmacokinetic terms, the peaks and troughs of a drug's blood levels ideally fit well within the therapeutic window of serum concentrations. For certain therapeutic agents, this window is so narrow that dosage formulation becomes critical.

In an attempt to address the need for improved bioavailability, several drug release modulation technologies have been developed. For example, poorly soluble 5,5 diphenylimidazolidine-2,4-diones have been derivatized into phosphate ester prodrugs to improve solubility. (Stella et at., U.S. Patent No. 4,260,769, 1981). Enteric coatings have been used as a protector of pharmaceuticals in the stomach and microencapsulating active agents using proteinaceous microspheres, liposomes or polysaccharides have been effective in abating enzymatic degradation of the active agent. Enzyme inhibiting adjuvants have also been used to prevent enzymatic degradation.
A wide range of pharmaceutical formulations provide sustained release through microencapsulation of the active agent in amides of dicarboxylic acids, modified amino acids or thermally condensed amino acids. Slow release rendering additives can also be intermixed with a large array of active agents in tablet formulations.
While microencapsulation and enteric coating technologies impart enhanced stability and time-release properties to active agent substances these technologies suffer from several shortcomings. Incorporation of the active agent is often dependent on diffusion into the microencapsulating matrix, which may not be quantitative and may complicate dosage reproducibility. In addition, encapsulated drugs rely on diffusion out of the matrix or degradation of the matrix, or both, which is highly dependent on the chemical properties and water solubility of the active agent. Conversely, water-soluble microspheres swell by an infinite degree and, unfortunately, may release the active agent in bursts with limited active agent available for sustained release. Furthermore, in some technologies, control of the degradation process required for active agent release is unreliable. For example, because an enterically coated active agent depends on pH to release the active agent and pH and residence time varies, the release rate is difficult to control.
Several implantable drug delivery systems have utilized polypeptide attachment to drugs. Additionally, other large polymeric carriers incorporating drugs into their matrices are used as implants for the gradual release of drug. Yet another technology combines the advantages of covalent drug attachment with liposome formation where the active ingredient is attached to highly ordered lipid films.
However there is still a need for an active agent delivery system that is able to deliver certain active agents which have been heretofore not formulated or difficult to formulate in a sustained release formulation for release over a sustained period of time and which is convenient for patient dosing.

2 There is a generally recognized need for sustained delivery of drugs that reduces the daily dosing requirement and allows for controlled and sustained release of the parent drug and also avoids irregularities of release and cumbersome formulations encountered with typical dissolution controlled sustained release methods.
SUMMARY OF THE INVENTION
The present invention accomplishes this by extending the period during which a lactam, amide, imide, sulfonamide, carbamate, urea, benzamide, acylaniline, and cyclic amide containing parent drug is released and absorbed after administration to the patient and providing a longer duration of action per dose than the parent drug itself In one embodiment, the compounds suitable for use in the methods of the invention are derivatives of lactam-, amide-, imide-, sulfonamide-, carbamate-, urea-, benzamide-, acylaniline-, and cyclic amide -containing parent drugs that are substituted at the amide nitrogen or oxygen atom with prodrug moieties. Preferably, the prodrug moieties are hydrophobic and reduce the polarity and solubility of the parent drug under physiological conditions.

Formula XLV Formula XLVI

The invention further relates the sustained delivery of a compound of Formula XLV
or XLVI by the administration of a compound of Formula I-III as shown in Scheme I. Upon administration of a compound of Formula I-III, the labile R1 moiety may be cleaved off enzymatically, chemically or through first phase metabolism giving a compound of Formula XLV or XLVI. Without being bound to any theory, it is postulated that for some of the compounds of Formula I-III, the release of a compound of Formula XLV or XLVI
upon cleavage of the R1 moiety results in a therapeutically active agent. For example such active ingredient can be aripiprazole, ziprasidone or bifeprunox. In one embodiment, the sustained release comprises a therapeutically effective amount of a compound of Formula XLV or XLVI in the blood stream of the patient for a period of at least about 8, preferably at least about 12, more preferably at least about 24 and even more preferably at least about 36 hours after administration of a compound of Formula I-III. In one embodiment, the compound of Formula XLV or XLVI is present in the blood stream of the patient for a period selected from: at least 48 hours, at least 4 days, at least one week, and at least one month. In one embodiment, a compound of Formula I-III is administered by injection.
Compounds of Formula IX, X, XI, XII, XIII, XIV, XXXIII, XXXIV, XXXV, XXXVI, and )(XXVII are useful for the treatment of neurological and psychological disorders. Neurological and psychiatric disorders include, but are not limited to, disorders such as cerebral deficit subsequent to cardiac bypass surgery and grafting, stroke, cerebral ischemia, spinal cord trauma, head trauma, perinatal hypoxia, cardiac arrest, hypoglycemic neuronal damage, dementia (including AIDS-induced dementia), Alzheimer's disease, Huntington's Chorea, amyotrophic lateral sclerosis, ocular damage, retinopathy, cognitive disorders, idiopathic and drug-induced Parkinson's disease, muscular spasms and disorders associated with muscular spasticity including tremors, epilepsy, convulsions, cerebral deficits secondary to prolonged status epilepticus, migraine (including migraine headache), urinary incontinence, substance tolerance, substance withdrawal (including, substances such as opiates, nicotine, tobacco products, alcohol, benzodiazepines, cocaine, sedatives, hypnotics, etc.), psychosis, schizophrenia, anxiety (including generalized anxiety disorder, panic disorder, social phobia, obsessive compulsive disorder, and post-traumatic stress disorder (PTSD)), mood disorders (including depression, mania, bipolar disorders), circadian rhythm disorders (including jet lag and shift work), trigeminal neuralgia, hearing loss, tinnitus, macular degeneration of the eye, emesis, brain edema, pain (including acute and chronic pain states, severe pain, intractable pain, neuropathic pain, inflammatory pain, and post-traumatic pain), tardive dyskinesia, sleep disorders (including narcolepsy), attention deficit/hyperactivity disorder, eating disorders and conduct disorder.
Definitions Listed below are definitions of various terms used to describe this invention.
These definitions apply to the terms as they are used throughout this specification and claims, unless otherwise limited in specific instances, either individually or as part of a larger group.
The term "aliphatic group" or "aliphatic" refers to a non-aromatic moiety that may be saturated (e.g. single bond) or contain one or more units of unsaturation, e.g., double and/or triple bonds. An aliphatic group may be straight chained, branched or cyclic, contain carbon, hydrogen or, optionally, one or more heteroatoms and may be substituted or unsubstituted. In addition to aliphatic hydrocarbon groups, aliphatic groups include, for example, polyalkoxyalkyls, such as polyalkylene glycols, polyamines, and polyimines, for example.
Such aliphatic groups may be further substituted. It is understood that aliphatic groups may include alkyl, substituted alkyl, alkenyl, substituted alkenyl, alkynyl, substituted alkynyl, and substituted or unsubstituted cycloalkyl groups as described herein.
The term "acyl" refers to a carbonyl substituted with hydrogen, alkyl, partially saturated or fully saturated cycloalkyl, partially saturated or fully saturated heterocycle, aryl, or heteroaryl. For example, acyl includes groups such as (C1-C6) alkanoyl (e.g., formyl, acetyl, propionyl, butyryl, valeryl, caproyl, t-butylacetyl, etc.), (C3-C6)cycloalkylcarbonyl (e.g., cyclopropylcarbonyl, cyclobutylcarbonyl, cyclopentylcarbonyl, cyclohexylcarbonyl, etc.), heterocyclic carbonyl (e.g., pyrrolidinylcarbonyl, pyrrolid-2-one-5-carbonyl, piperidinylcarbonyl, piperazinylcarbonyl, tetrahydrofuranylcarbonyl, etc.), aroyl (e.g., benzoyl) and heteroaroyl (e.g., thiopheny1-2-carbonyl, thiopheny1-3-carbonyl, furany1-2-carbonyl, furany1-3-carbonyl, 1H-pyrroy1-2-carbonyl, 1H-pyrroy1-3-carbonyl, benzo[b]thiopheny1-2-carbonyl, etc.). In addition, the alkyl, cycloalkyl, heterocycle, aryl and heteroaryl portion of the acyl group may be any one of the groups described in the respective definitions. When indicated as being "optionally substituted", the acyl group may be unsubstituted or optionally substituted with one or more substituents (typically, one to three substituents) independently selected from the group of substituents listed below in the definition for "substituted" or the alkyl, cycloalkyl, heterocycle, aryl and heteroaryl portion of the acyl group may be substituted as described above in the preferred and more preferred list of substituents, respectively.

The term "alkyl" is intended to include both branched and straight chain, substituted or unsubstituted saturated aliphatic hydrocarbon radicals/groups having the specified number of carbons. Preferred alkyl groups comprise about 1 to about 24 carbon atoms ("C1-C24") preferably about 7 to about 24 carbon atoms ("C7-C24"), preferably about 8 to about 24 carbon atoms ("C8-C24"), preferably about 9 to about 24 carbon atoms ("C9-C24"). Other preferred alkyl groups comprise at about 1 to about 8 carbon atoms ("C1-C8") such as about 1 to about 6 carbon atoms ("C1-C6"), or such as about 1 to about 3 carbon atoms ("C1-C3").
Examples of C1-C6 alkyl radicals include, but are not limited to, methyl, ethyl, propyl, isopropyl, n-butyl, tert-butyl, n-pentyl, neopentyl and n-hexyl radicals.
The term "alkenyl" refers to linear or branched radicals having at least one carbon-carbon double bond. Such radicals preferably contain from about two to about twenty-four carbon atoms ("C2-C24") preferably about 7 to about 24 carbon atoms ("C7-C24"), preferably about 8 to about 24 carbon atoms ("C8-C24"), and preferably about 9 to about 24 carbon atoms ("C9-C24"). Other preferred alkenyl radicals are "lower alkenyl"
radicals having two to about ten carbon atoms ("C2-C10") such as ethenyl, allyl, propenyl, butenyl and 4-methylbutenyl. Preferred lower alkenyl radicals include 2 to about 6 carbon atoms ("C2-C6").
The terms "alkenyl", and "lower alkenyl", embrace radicals having "cis" and "trans"
orientations, or alternatively, "E" and "Z" orientations.
The term "alkynyl" refers to linear or branched radicals having at least one carbon-carbon triple bond.

Pharmaceutical Compositions The pharmaceutical compositions of the present invention comprise a therapeutically effective amount of a compound of the present invention formulated together with one or more pharmaceutically acceptable carriers or excipients.
As used herein, the term "pharmaceutically acceptable carrier or excipient"
means a non-toxic, inert solid, semi-solid, gel or liquid filler, diluent, encapsulating material or formulation auxiliary of any type. Some examples of materials which can serve as pharmaceutically acceptable carriers are sugars such as lactose, glucose and sucrose;
cyclodextrins such as alpha- (a), beta- (f3) and gamma- (y) cyclodextrins;
starches such as corn starch and potato starch; cellulose and its derivatives such as sodium carboxymethyl cellulose, ethyl cellulose and cellulose acetate; powdered tragacanth; malt;
gelatin; talc;
excipients such as cocoa butter and suppository waxes; oils such as peanut oil, cottonseed oil, safflower oil, sesame oil, olive oil, corn oil and soybean oil; glycols such as propylene glycol;
esters such as ethyl oleate and ethyl laurate; agar; buffering agents such as magnesium hydroxide and aluminum hydroxide; alginic acid; pyrogen-free water; isotonic saline;
Ringer's solution; ethyl alcohol, and phosphate buffer solutions, as well as other non-toxic compatible lubricants such as sodium lauryl sulfate and magnesium stearate, as well as coloring agents, releasing agents, coating agents, sweetening, flavoring and perfuming agents, preservatives and antioxidants can also be present in the composition, according to the judgment of the formulator.
The pharmaceutical compositions of this invention may be administered orally, parenterally, by inhalation spray, topically, rectally, nasally, buccally, vaginally or via an implanted reservoir. In a preferred embodiment, administration is parenteral administration by injection.
The pharmaceutical compositions of this invention may contain any conventional non-toxic pharmaceutically-acceptable carriers, adjuvants or vehicles. In some cases, the pH
of the formulation may be adjusted with pharmaceutically acceptable acids, bases or buffers to enhance the stability of the formulated compound or its delivery form. The term parenteral as used herein includes subcutaneous, intracutaneous, intravenous, intramuscular, intraarticular, intraarterial, intrasynovial, intrasternal, intrathecal, intralesional and intracranial injection or infusion techniques.
Liquid dosage forms for oral administration include pharmaceutically acceptable emulsions, microemulsions, solutions, suspensions, syrups and elixirs. In addition to the active compounds, the liquid dosage forms may contain inert diluents commonly used in the art such as, for example, water or other solvents, solubilizing agents and emulsifiers such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butylene glycol, dimethylformamide, oils (in particular, cottonseed, groundnut, corn, germ, olive, castor, and sesame oils), glycerol, tetrahydrofurfuryl alcohol, polyethylene glycols and fatty acid esters of sorbitan, and mixtures thereof Besides inert diluents, the oral compositions can also include adjuvants such as wetting agents, emulsifying and suspending agents, sweetening, flavoring, and perfuming agents.
Injectable preparations, for example, sterile injectable aqueous or oleaginous suspensions, may be formulated according to the known art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation may also be a sterile injectable suspension or emulsion, such as INTRALIPID , LIPOSYN OR OMEGAVEN , or solution, in a nontoxic parenterally acceptable diluent or solvent, for example, as a solution in 1,3-butanediol. NTRALIPID is an intravenous fat emulsion containing 10-30%
soybean oil, 1-10% egg yolk phospholipids, 1-10% glycerin and water. LIPOSYN is also an intravenous fat emulsion containing 2-15% safflower oil, 2-15% soybean oil, 0.5-5% egg phosphatides 1-10% glycerin and water. OMEGAVEN is an emulsion for infusion containing about 5-25% fish oil, 0.5-10% egg phosphatides, 1-10% glycerin and water.
Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution, USP and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil can be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid are used in the preparation of injectables.
The injectable formulations can be sterilized, for example, by filtration through a bacterial-retaining filter, or by incorporating sterilizing agents in the form of sterile solid compositions which can be dissolved or dispersed in sterile water or other sterile injectable medium prior to use.

Additional sustained release in accordance with the invention may be accomplished by the use of a liquid suspension of crystalline or amorphous material with poor water solubility. The rate of absorption of the drug then depends upon its rate of dissolution, which, in turn, may depend upon crystal size and crystalline form.
Alternatively, delayed absorption of a parenterally administered drug form is accomplished by dissolving or suspending the drug in an oil vehicle. Injectable depot forms are made by forming microencapsule matrices of the drug in biodegradable polymers such as polylactide-polyglycolide. Depending upon the ratio of drug to polymer and the nature of the particular polymer employed, the rate of drug release can be controlled. Examples of other biodegradable polymers include poly(orthoesters) and poly(anhydrides). Depot injectable formulations are also prepared by entrapping the drug in liposomes or microemulsions that are compatible with body tissues.
In one preferred embodiment, the formulation provides a sustained release delivery system that is capable of minimizing the exposure of the prodrug to water.
This can be accomplished by formulating the prodrug with a sustained release delivery system that is a polymeric matrix capable of minimizing the diffusion of water into the matrix.
Suitable polymers comprising the matrix include polylactide (PLA) polymers and the lactide/glycolide (PLGA) co-polymers.
Alternatively, the sustained release delivery system may comprise poly-anionic molecules or resins that are suitable for injection or oral delivery. Suitable polyanionic molecules include cyclodextrins and polysulfonates formulated to form a poorly soluble mass that minimizes exposure of the prodrug to water and from which the prodrug slowly leaves.
Compositions for rectal or vaginal administration are preferably suppositories which can be prepared by mixing the compounds of this invention with suitable non-irritating excipients or carriers such as cocoa butter, polyethylene glycol or a suppository wax which are solid at ambient temperature but liquid at body temperature and therefore melt in the rectum or vaginal cavity and release the active compound.
Solid dosage forms for oral administration include capsules, tablets, pills, powders, and granules. In such solid dosage forms, the active compound is mixed with at least one inert, pharmaceutically acceptable excipient or carrier such as sodium citrate or dicalcium phosphate and/or: a) fillers or extenders such as starches, lactose, sucrose, glucose, mannitol, and silicic acid, b) binders such as, for example, carboxymethylcellulose, alginates, gelatin, polyvinylpyrrolidinone, sucrose, and acacia, c) humectants such as glycerol, d) disintegrating agents such as agar-agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate, e) solution retarding agents such as paraffin, f) absorption accelerators such as quaternary ammonium compounds, g) wetting agents such as, for example, cetyl alcohol and glycerol monostearate, h) absorbents such as kaolin and bentonite clay, and i) lubricants such as talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, and mixtures thereof In the case of capsules, tablets and pills, the dosage form may also comprise buffering agents.
Solid compositions of a similar type may also be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugar as well as high molecular weight polyethylene glycols and the like.
The solid dosage forms of tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells such as enteric coatings and other coatings well known in the pharmaceutical formulating art. They may optionally contain opacifying agents and can also be of a composition that they release the active ingredient(s) only, or preferentially, in a certain part of the intestinal tract, optionally, in a delayed manner.
Examples of embedding compositions that can be used include polymeric substances and waxes.
Dosage forms for topical or transdermal administration of a compound of this invention include ointments, pastes, creams, lotions, gels, powders, solutions, sprays, inhalants or patches. The active component is admixed under sterile conditions with a pharmaceutically acceptable carrier and any needed preservatives or buffers as may be required. Ophthalmic formulation, ear drops, eye ointments, powders and solutions are also contemplated as being within the scope of this invention.
The ointments, pastes, creams and gels may contain, in addition to an active compound of this invention, excipients such as animal and vegetable fats, oils, waxes, paraffins, starch, tragacanth, cellulose derivatives, polyethylene glycols, silicones, bentonites, silicic acid, talc and zinc oxide, or mixtures thereof Powders and sprays can contain, in addition to the compounds of this invention, excipients such as lactose, talc, silicic acid, aluminum hydroxide, calcium silicates and polyamide powder, or mixtures of these substances. Sprays can additionally contain customary propellants such as chlorofluorohydrocarbons.
Transdermal patches have the added advantage of providing controlled delivery of a compound to the body. Such dosage forms can be made by dissolving or dispensing the compound in the proper medium. Absorption enhancers can also be used to increase the flux of the compound across the skin. The rate can be controlled by either providing a rate controlling membrane or by dispersing the compound in a polymer matrix or gel.

For pulmonary delivery, a therapeutic composition of the invention is formulated and administered to the patient in solid or liquid particulate form by direct administration e.g., inhalation into the respiratory system. Solid or liquid particulate forms of the active compound prepared for practicing the present invention include particles of respirable size:
that is, particles of a size sufficiently small to pass through the mouth and larynx upon inhalation and into the bronchi and alveoli of the lungs. Delivery of aerosolized therapeutics, particularly aerosolized antibiotics, is known in the art (see, for example U.S. Patent No.
5,767,068 to VanDevanter etal., U.S. Patent No. 5,508,269 to Smith et al., and WO
98/43650 by Montgomery).
By a "therapeutically effective amount" of a prodrug compound of the invention is meant an amount of the compound which confers a therapeutic effect on the treated subject, at a reasonable benefit/risk ratio applicable to any medical treatment. The therapeutic effect may be objective (i.e., measurable by some test or marker) or subjective (i.e., subject gives an indication of or feels an effect).
In accordance with the invention, the therapeutically effective amount of a prodrug of the invention is typically based on the target therapeutic amount of the parent drug.
Information regarding dosing and frequency of dosing is readily available for many parent drugs from which the prodrugs of the invention are derived and the target therapeutic amount can be calculated for each prodrug of the invention. In accordance with the invention, the same dose of a prodrug of the invention provides a longer duration of therapeutic effect as compared to the parent drug. Thus if a single dose of the parent drug provides 12 hours of therapeutic effectiveness, a prodrug of that same parent drug in accordance with the invention that provides therapeutic effectiveness for greater than 12 hours will be considered to achieve a "sustained release".
The precise dose of a prodrug of the invention depends upon several factors including the nature and dose of the parent drug and the chemical characteristics of the prodrug moiety linked to the parent drug. Ultimately, the effective dose and dose frequency of a prodrug of the invention will be decided by the attending physician within the scope of sound medical judgment. The specific therapeutically effective dose level and dose frequency for any particular patient will depend upon a variety of factors including the disorder being treated and the severity of the disorder; the activity of the specific compound employed; the specific composition employed; the age, body weight, general health, sex and diet of the patient; the time of administration, route of administration, and rate of excretion of the specific compound employed; the duration of the treatment; drugs used in combination or contemporaneously with the specific compound employed; and like factors well known in the medical arts.

Pharmacokinetic Evaluation in Rats Pharmacokinetic Evaluation of Prodrugs in Rats Following Oral Administration (PO) Animals: Male Sprague¨Dawley rats (Charles River Laboratories, Wilmington, MA) were obtained. Approximately 24 rats were used in each study. Rats were approximately 350-375 g at time of arrival. Rats were housed 2 per cage with ad libitum chow and water.
Environmental conditions in the housing room: 64-67 F, 30% to 70% relative humidity, and 12:12-h light: dark cycle. All experiments were approved by the institutional animal care and use committee.
Pharmacokinetics study: Rats were dosed 10mg/kg (3.3mL suspension) of the test compound (see Table E). Blood samples were collected from the jugular vein after brief anesthesia with Isoflurane. A 271/2G needle and lcc syringe without an anticoagulant was used for the blood collection. Approximately 2504 of whole blood was collected at each sampling time-point of 15 and 30 minutes, and 1, 2, 4, 7 and 24 hours after administration.
Once collected, whole blood was immediately transferred prechilled tubes containing EDTA, inverted 10-15 times and immediately placed on ice. The tubes were centrifuged for 2 minutes at >14,000 g's (11500 RPMs using Eppendorf Centrifuge) at room temperature to separate plasma. Plasma samples were transferred to labeled plain tubes (MICROTAINERt) and stored frozen at < -70 C.
Data Analysis: Drug concentrations in plasma samples were analyzed by liquid chromatography¨mass spectroscopy using appropriate parameters for each compound. Half-life, volume of distribution, clearance, maximal concentration, and AUC were calculated by using WinNonlin Version 5.2 software (Pharsight, St. Louis, MO). Results are shown in The Figure.
