The compounds of Formula I and Formula II are effective over a wide dosage range; however, it is desirable to administer a dosage that is as low as possible. The amount of NSAIDS present in the composition is adjusted as described above in ratio to the Formula I or Formula II dosage. The amount of acetaminophen present in the composition is adjusted as described above in ratio to the Formula I or Formula II dosage. For example, dosages per day of the Formula II compounds will normally fall within the range of about 0.005 to about 100 mg/kg of body weight and the acetaminophen in the composition would be from 3 to 1000 times this amount. For example, dosages per day of the Formula I compounds will normally fall within the range of about 0.005 to about 100 mg/kg of body weight and the NSAIDS in the composition would be from 3 to 1000 times this amount.
In the composition of thiε invention a Compound selected from the group consisting of Formula I and Formula II; or a pharmaceutically acceptable salt thereof and one or more opioid compounds are combined in a weight ratio of Compound to opioid compound of from about 1 to about 1000.
A preferred composition is a weight ratio of Compound to opioid compound of from about 1 to about 100. An especially preferred ratio is from about 1 to about 30. A further preferred ratio may be from about 1 to about 10. A final preferred ratio may be from about 1 to about 3.
The Compounds are effective over a wide dosage range; however, it is desirable to administer a dosage that is as low as possible. The amount of opioid compound present in the composition is adjusted as described above in ratio to the Compound dosage. For example, dosages per day of the Formula I compounds will normally fall within the range of about 0.005 to about 100 mg/kg of body weight and the opioid compound in the composition would be from 3 to 1000 times this amount.
However, for each composition claimed herein, it will be understood that the amount of the Compound actually administered will be determined by a physician, in the light of the relevant circumstances including the condition to be treated, the choice of Compound to be administered, the age, weight, and response of the individual patient, the severity of the patient's symptoms, and the chosen route of administration, and therefore the above dosage ranges are not intended to limit the scope of the invention in any way. While the present compounds are preferably administered orally to humans susceptible to or suffering from pain, the compoundε may also be administered by a variety of other routes such as the transdermal, parenterally, subcutaneous, intranasal, intramuscular and intravenous routes. Such formulations may be designed to provide delayed or controlled release using formulation techniques which are known in the art .
Transdermal formulations containing the composition claimed herein most preferably deliver the active substances in an effective amount for from about three days to about seven days. However, for chronic pain such as arthritis or cancer pain, a transdermal delivery of from about three days to up to about two weeks is desirable. Alternatively, it may be preferred to deliver the claimed compositions transdermally in an effective amount for from about one day to about three days .
As used herein the term "treating" includes prophylaxis of a physical and/or mental condition or amelioration or elimination of the developed physical and/or mental condition once it has been established or alleviation of the characteristic symptoms of such condition.
The compounds of Formula I and Formula II employed in the invention are not believed to act via the GABA/benzodiazepine, 5HT1A, or Dl receptor systems in humans. Rather, the activity of the present Formula I and Formula II compounds as analgesic agents is believed to be based upon modulation of muscarinic cholinergic receptors. However, the mechanism by which the present compounds function is not necessarily the mechanism stated supra . , and the present invention is not limited by any mode of operation.
The compounds of Formula I and Formula II are described in Sauerberg et al . in U.S. Patents 5,043,345, 5,041,455 and 5,260,314 (collectively herein "Sauerberg Patents"), each of which is herein incorporated by reference. The Sauerberg Patents teach the artisan how to make the compounds of Formula I and Formula II used herein for the claimed analgesic composition. Examples of pharmaceutically acceptable salts include inorganic and organic acid addition salts such as hydrochloride, hydrobromide, sulphate, phosphate, acetate, fumarate, maleate, citrate, lactate, tartrate, oxalate, or similar pharmaceutically-acceptable inorganic or organic acid addition salts, and include the pharmaceutically acceptable salts listed in Journal of Pharmaceutical Science. 66, 2 (1977) which are known to the skilled artisan. The compounds of this invention may form solvates with standard low molecular weight solvents using methods known to the skilled artisan.
The route of administration may be any route, which effectively transports the active compound to the appropriate or desired site of action, such as oral or parenteral e.g. rectal, transdermal, depot, subcutaneous, intravenous, intramuscular or intranasal, the oral route being preferred.
The dosage administered will, of course, vary depending on known factors such as the pharmacodynamic characteristics of the particular agent, and it smode and route of administration; age, health, and weight of the recipient; nature and extent of the symptoms, kind of concurrent treatment, frequency of treatment, and the effect desired. Usually, the daily dosage can be such that the active ingredient is administered at a daily dosage of from about 0.2 mg/kg to about 100 mg/kg of body weight Formula I or Formula II compound and from about 0.6 to about 200 mg/kg of NSAIDS. Compositions suitable for internal administration contain from about one half (0.5) milligrams to about 600 milligrams of active ingredient per unit. In these pharmaceutical compositions, the active ingredient will ordinarily be present in an amount of from about 0.5% to about 95% by weight based on the total weight of the composition. For compositions containing acetaminophen, usually, the daily dosage can be such that the active ingredient is administered at a daily dosage of from about 0.2 mg/kg to about 100 mg/kg of body weight Formula II compound and from about 0.6 to about 200 mg/kg of acetaminophen.
Typical compositions include a compound of Formula I or Formula II or a pharmaceutically acceptable acid addition salt thereof and one or more NSAIDSs, associated with a pharmaceutically acceptable excipient which may be a carrier, or a diluent or be diluted by a carrier, or enclosed within a carrier which can be in the form of a capsule, sachet, paper, or other container. In making the compositions, conventional techniques for the preparation of pharmaceutical compositions may be used. For example, the active compound will usually be mixed with a carrier, or diluted by a carrier, or enclosed within a carrier which may be in the form of a ampoule, capsule, sachet, paper, or other container. When the carrier serves aε a diluent, it may be solid, semi-solid, or liquid material which acts as a vehicle, excipient, or medium for the active compound. The active compound can be adsorbed on a granular solid container for example in a sachet. Some examples of suitable carriers are water, salt solutions, alcohols, polyethylene glycols, polyhydroxyethoxylated castor oil, gelatine, lactose, amylose, magnesium stearate, talc, silicic acid, fatty acid monoglycerides and diglycerides, pentaerythritol fatty acid esters, hydroxymethylcellulose and polyvinylpyrrolidone. The formulations may also include wetting agents, emulsifying and suspending agents, preserving agents, sweetening agents, or flavoring agents. The formulations of the invention may be formulated so as to provide quick, sustained, or delayed release of the active ingredient after administration to the patient by employing procedures well known in the art. Typical compositions include a compound of Formula I or Formula II or a pharmaceutically acceptable acid addition salt thereof and acetaminophen, associated with a pharmaceutically acceptable excipient which may be a carrier, or a diluent or be diluted by a carrier, or enclosed within a carrier which can be in the form of a capsule, sachet, paper, or other container. In making the compositions, conventional techniques for the preparation of pharmaceutical compositions may be used, as described above.
A preferred composition is a weight ratio of Compound to central alpha-adrenergic active compound of from about 1 to about 100. An especially preferred ratio is from about 1 to about 30. A further preferred ratio may be from about 1 to about 10. A final preferred ratio may be from about 1 to about 3.
The compounds of Formula I and Formula II are effective over a wide dosage range; however, it is desirable to administer a dosage that is as low as possible. The amount of central alpha-adrenergic active compound present in the composition is adjusted as described above in ratio to the Formula I or Formula II dosage. For example, dosages per day of the Formula I compounds will normally fall within the range of about 0.005 to about 100 mg/kg of body weight and the central alpha-adrenergic active compound in the composition would be from 3 to 1000 times this amount.
Usually, the daily dosage can be such that the active ingredient is administered at a daily dosage of from about 0.2 mg/kg to about 100 mg/kg of body weight Formula I or Formula II compound and from about 0.6 to about 200 mg/kg of central alpha-adrenergic active compound.
Typical compositions include a compound of formula I or Formula II or a pharmaceutically acceptable acid addition salt thereof; and one or more central alpha- adrenergic active compounds, associated with a pharmaceutically acceptable excipient which may be a carrier, or a diluent or be diluted by a carrier, or enclosed within a carrier which can be in the form of a capsule, sachet, paper, or other container. In making the compositions, conventional techniqueε for the preparation of pharmaceutical compoεitionε may be used.
The pharmaceutical preparations can be sterilized and mixed, if desired, with auxiliary agents, emulsifiers, salt for influencing osmotic preεsure, buffers and/or coloring substances and the like, which do not deleteriously react with the active compounds.
For parenteral application, particularly suitable are injectable solutions or suspenεionε, preferably aqueous solutions with the active compound disεolved in polyhydroxylated castor oil.
Tablets, dragees, or capsules having talc and/or a carbohydrate carrier or binder or the like are particularly suitable for oral application. Preferable carriers for tablets, dragees, or capsules include lactose, corn starch, and/or potato starch. A syrup or elixir can be used in cases where a sweetened vehicle can be employed.
Generally, the Formula I or Formula II compounds are dispensed in unit form comprising from about 0.1 to about 100 mg in a pharmaceutically acceptable carrier per unit dosage.
The compositions of this invention may be suitable for administration to an animal. Such animals include both domestic animals, for example livestock, laboratory animals, and household pets, and non-domestic animals such as wildlife. More preferredly, the animal is a vertebrate. Most preferredly, a compound of this invention shall be administered to a mammal. It is especially preferred that the animal is a domestic mammal or a human. The most preferred mammal is a human. For such purposes, a compound of this invention may be administered as a feed additive.
The following models and assays are useful for illustrating the effectiveness of the compositions claimed herein.
Nocieeptive pain model:
Acetic acid-induced writhing: A standard procedure for detecting and comparing the analgesic activity of different classes of analgesic drugs for which there is a good correlation with human analgesic activity is the prevention of acetic acid-induced writhing in mice. Mice, are subcutaneously administered various doses of the claimed composition and are injected injected intraperitoneally with acetic acid (0.5% solution, 10 ml/kg) 5 min prior to a designated observation period. For scoring purposes a "writhe" is indicated by whole body stretching or contraction of the abdomen during the observation period beginning 5 min after receiving the acetic acid. Inhibition of writhing behavior is demonstrative of analgesic activity.

qeyropathic pain iwpdel;
Sciatic nerve ligation model: Rats are anesthetized and a nerve ligation procedure performed. The common sciatic nerve is exposed and 4 ligatures tied loosely around it with about 1 mm spacing. One day to 10 weeks after surgery, the nocieeptive testing is performed. Responses to noxious heat are determined by placing the rats in a chamber with a clear glass floor and aiming at the plantar surface of the affected foot a radiant heat source from beneath the floor. Increased latency to withdraw the hindpaw is demonstrative of analgesic activity. Responses to normally innocuous mechanical stimuli is determined by placing the rats in a chamber with a screen floor and stimulating the plantar surface of the hind paw with graduated von Frey hairs which are calibrated by the grams of force required to bend them. Rats with sciatic nerve ligation respond to lower grams of mechanical stimulation by reflexive withdrawal of the foot than unoperated rats. This response to stimuli which are normally innocuous is termed allodynia. Increases in the grams of mechanical force required to produce foot withdrawal is demonstrative of antiallodynic activity.

Systemic and supraspinal, but not spinal, opiates suppreεs allodynia in a rat neuropathic pain model. Neuroci Lett 186 (1995) 111-114. Formalin paw test: Rats are anesthetized and when there is a loss of spontaneous movement the rats are injected subcutaneously in the dorεal εurface of the hindpaw with 50 ul of 5% formalin solution using a 30 gauge needle. Rats are then individually placed in an open Plexiglas chamber for observation, and within a maximum interval of 1 to 2 min, the animal displays recovery from anesthesia with spontaneous activity and normal motor function. Pain behavior is quantified by periodically counting the incidents of spontaneous flinching/shaking of the injected paw. The flinches are counted for 1-min periods at 1- to 2-, 5- to 6- and 5min intervals during the interval from 10 to 60 min. Inhibition of the pain behavior is demonstrative of an analgesic activity.

Brewer's yeast-induced hyperalgesia (Randall-Selitto Test) : To assess nocieeptive threshold in rats, ascending pressure is applied gradually to the paw with a motor driven weight of a Ugo Basile Analgesy Meter. Rats respond to the pressure by either pulling free of the device, struggling or vocalizing. Hyperalgesia is induced by a hind paw subplantar injection of 0.1 ml of 1% suspension of brewer's yeast in 0.9% saline. The composition of this invention is administered at varying times ( 0 - 4 hr) after injection of brewer's yeast and pressure threshold for the inflamed paw again determined at varying times. Increases in the pressure which produces a behavioral response is demonstrative of analgesic activity.

Utility Test Methods The unexpectedly enhanced analgesic activity of the composition of the invention is evidenced by tests intially conducted on mice. Male mice are fasted for 16-22 hours and weighed. Mice weighing from about 18-22 grams at the time of testing are used for the following studies. All mice are dosed sequentially by the oral route with suspensions of a composition of this invention. Doses are coded using a code unknown to the observer.
A stock suspension of the test composition is prepared by mixing the active ingredients with about 40 mL of an aqueous vehicle containing about 2% Tween 80 (R) , a pharmacological dispersant and containing 100% polysorbate 80, and 1% by weight Methocel (R) MC powder, and containing 100% methylcellulose, in distilled water. The mixture may be sonicated for about 10 to about 15 seconds using an ultrasound sytem. All dosing suspensions are prepared by dilution of the stock suspension with Methocel/Tween 80. All suspensions are used within two hours of preparation.
Mouse Writhing Test
An accepted standard for detecting and comparing the analgesic activity of different classes of analgesic compounds for which there is a good correlation with human analgesic activity is the prevention of phenyl-p- benzoquinone induced writhing in mice. [H. Blumberg et al . Proc. Soc. Exp. biol. Med., 118, 763-766 (1965)] .
Mice, treated with various doses of compound of Formula I or Formula II, composition or vehicle are injected intraperitoneally with a standard challenge dose of phenyl-p-benzoquinone 5 minutes prior to a designated observation period. The pheyl-p-benzoquinone is prepared as about 0.1 mg/ml solution in about 5% by volume of ethanol in water. The writhing dose is 1.25 mg/kg injected at a volume of about 0.25ml/10g. For scoring purposes a "writhe" is indicated by whole body stretching or contracting of the abdomen during an observation period beginning about five minutes after the phenyl-p- benzoquinone dose.
All ED50 values and their 95% confidence limits are determined using accepted numerical methodε. For example, see W.F. Thompson, Bacteriological Rev.. 11, 115-
145 (1947) . The interaction of the dosages on phenyl-p- benzoquinone induced writhing in mice is demonstrated by the Loewe isobologram (S. Loewe, Pharm. Rev. 9, 237-242 (1957) .
The solid line connecting the ED50 dosages of Formula I or Formula II (alone) and classical analgesic as claimed herein (alone) represents the "ED50 addition line" which indicates the expected location of the ED50's for Formula I or Formula II and classical analagesic combinations if simple additivity were to describe their combined effects. The 95% confidence range for the ED50 addition line is shown by the area between the broken lines above and below the ED50 addition line.
According to Loewe' s isobolic theory, if the analgesic effects are simply additive to one another, then the expected location of the ED50's of the Formula I or
Formula II and classical analgesic component of each fixed dosage ratio would be contained within or overlap the region of the ED50 addition line. Combination ED50 ' s located significantly below the ED50 addition line would represent unexpectedly enhanced analgesic activity and combination ED50 ' s located above the line would represent unexpected diminished analgesic effect.
One method to establish the significance of such unexpected enhanced or diminished activity is to calculate the best fitting polynomial regression line to the observed ED50's using standard mathematical techniques.
Such experiments demonstrate that compositions comprised of a compound of Formula I or Formula II and one or more classical analgesics provides a statistically significant synergistic analgesic effect.
