(Cl. 167-65) This invention relates to novelcomposition and method of potentiating ataractic, analgesic, hypnotic, and myorelaxing drugs.
This application is a continuation-in-part of application more; treatments very often must be continued for long,
periods of time and thus, give rise to the danger of chronic toxicity. Another important object of the present invention is to provide nontoxic potentiatingcompounds'for the above listed drugs. The potentiating compounds of the invention not only are such as to exhibit-no unpleasant sideefiects when administered in conjunction with anyof the ataractic, analgesic, hypnotic and'myorelaxing drugs referred to above, but also are themselves inert and harmless substances if administered alone.
Among" the ataractic, analgesic, hypnotic, and myore laxing drugs liable to be potentiated according to the method of this invention-the following can be mentioned:
Barbiturates in general, such as-S-phenyl-S-ethyl-ba-rbituric (Phenobarbital) and S-ethyl-S-(l-methylbutyI)-'barbituric acids (Pentobarbita Opium alkaloids; such as morphine and total extracts of opium alkaloids (Pantopon);
Analgesic-spasmolytic drugs, such as l-alkyl-4-phenylpiperidine-4-alkyl (Pethidine) Ataraxics such as Meprobamate (2-n-propyl-l-,3- propanediol-dicarbamate), and Fenaglycodol 2-pchloro'phenyl-3 1nethyl 2,3 -butanediol;
Analgesics of 1tlie'lviethadone class such as 6 dimethylamino-4, 4-diphenyl-3-heptanone and derivativesthereof;
Skeletal-muscle relaxing, curare-like drugs, suchas tris-{diethylamino ethyl-hydroxy]-1,2,3-benZene-triiodoethylate [Gallamine and similar compounds;
Myorelaxing drugs, such as fMethocarbamol (3-0- niethoxyphenoxy-2-hydroxypropl-carbamate), and derivatives thereof.
illustrative of the potentiating ;'compounds which may be' used in performing themethod' and in forming the compositions accordingto the present invention are: a [(-prchlorophenyl) a-phenyH- l-pyridyl carbinol; and the nontoxic, phannacologically acceptable salts thereof.
carbonate andderivatives thereof ICE:
proven to? be valuable as an agent capable of potentiat ing' the actionofanalgesics, tranquilizers, sedatives" and'i hypnotics and; ingeneral, the neurot'r opic drugs acting? on the nervous centrahsystem: The above identified compound has also shown "a "markedpotenti'atingfiactioii" towards skeletal rnus'cle' loosening, curarelike' drugs," and myorelaxingdrugs' in general;
Thus, according to theinv'ention; we'provide a medicinal preparation comprising a centrally acting drug"sej-' lected' from the groupcon'sistin'g "of barbiturates, opium alkaloids; 1methyl-4=phenyl-piperidine 4-ethyl carbonate; 2 methyl2-n-propyl-1,3 propanediol-dicarbamate, 6- diinethylamino-4,4-diphenyl-3-heptanone and 2-p-chlorophenyl-3-methyl 2,3-butanediol, and w-- -[(p-chloro phenyl)-a-phenyl]-4-pyridyl-carbino1,- which acts as a potentiating compound capable of substantially increas ing the effectiveness of thecentra'lIy acting drug. 7 Also, according to the invention; we provide a Inedicinal preparation comprising a myorelaxin'g'drug selected from the group comprising tris-[diethylamino-ethylehydroxy] 1,2,3-benzene triiodoethylate and 3-o-methoxyphenoxy-Z-hydroxy-propyl-carbamate, e and their deriva tives, and ot-[(p-chlorophenyl)-u-phenyl]-4-pyridyl-+ cari binol, which acts as a potentiatingcompound capable of substantially increasing the myorelaxing effectiveness of said myorel'axing drug' i v a Our invention provides, moreover; a method of potentiating the 'ataractic, analgesic and l'fypnoticeffect of a centrally acting drug selected from the group'consisting of barbituratcs, opium alkaloids, Z-methyI Z-n ropyl-EI,3; propanediol dicarbamate, 1-alkyl- 1-pheny1-piperidine-4- alkyl carbonates, 6 dimethylamino-4,4-diphenyl-3-heptanone and 2-p-chlorophenyl-3-methyl-3,3i butanediol which comprises administering internally, for combined physiological action with said drug, a suitable dosage of a (p-chlorophenyl) -a-phenyl] -4-pyridyl-carbinol.
According to our said invention, a method is also provided for potentiating the'myorelaxing'effe'ct of a muscle relaxing drug selected from .the group comprising. tris- [die thylaminoethyl hydroxy] -1 ,2,3 -benzene' triiodoethyl ate and 3-o-methoxy-phenoxy-2-hydroxpropyl' 'carbiamate, and their derivatives, which comprises administeringin'ternally, .for combined physiological action-with said'myor'elaxing drug a suitable dosage-"of 'a-[--p-chlorophenyl) -a-phenyl] -.4-pyridylcarbine I The potentiating compound of the 'instantinvention may be prepared by a number of; differentv chemical:
W processes, for example byrefluxing 4-p-"chlorobenzjoyl 50" pyridine with an organic magnesium compound of the? structure XMgR wherein X is an atom of "a halogen having an atomic weight higher than 19-and R is -a mernber selected from the group consistingof analkyl radical having not more than Scarbon atoms, aphenyl radical, and a phenylalkyl radical having not niore'th an -11 carbon atoms, as disclosed in our application tor Letters Patent of the United States Serial No. 687,375, filed October 1, 1957, of which this application is acontinuanon-impart] I In the practical use of the potentiating compound of the invention it has been found expedient to administer the potentiating compound first, land in general from so'minutes' to '1 hour before administering are drug "whhse same obtained by administering the potentiating corn- 5 pound first.
Thus, the compositions of this invention may be advantageously employed in multiple doses and in timed delay tablets and the like. Due to the relative insolubility of the potentiating compound of the invention in aqueous 10 media they do not lend themselves to administration by injections so that the preferred form of administration ought to be one permitting the difiusion of the potentiating compound through the organism without the intermediary of liquidmedia. Thus, administration by tablets 15 and suppositories is preferred but this is not, of course, the only form of administration, since any other form which does not require solubilization of the potentiating compound is equally well adapted to the purpose.
As has been outlined hereinbefore, the potentiating 20 compound of the invention is itself harmless and an inert substance since the product is tolerated by animals (mice) in doses up to 3 gms. per kgm. body weight (acute tox- 4 icity), and for 40 days at the daily dose of 50 mgms. per kgm. body weight. The latter dose is at least 100 times the dosage required in order that an appreciable potentiating effect might be observed in the same animals.
Clinical tests have been carried out on human beings by administering the potentiating compound of the invention alone; no alteration in the morbid pattern of the patients thus treated has ever been observed.
Generally speaking, the selected potentiat-ing compound will be used in single doses of from about 10 to about 20 mgms, the daily dose being liable to vary from about 20 to about 100 mgms. The amount of potentiating compound will, of course, vary widely depending on the drug to be potentiated, the potentiating efiect desired and the nature of the disease being treated.
Also, the amount of the selected drug to be potentiated will vary widely depending on the physiological effect to be achieved. Generally speaking, it is desirable to employ from about the standard efiective therapeutic dose of the selected drug to about one-third the standard dose.
The following Table 1 reports practical examples of modes of practicing the method of the invention and making the medical preparations therefor.

With particular respect to'the po tentiating eifect shown time, during which the righting reflex was abse'ntfo'llowing, theadministrationof -apotentia'ted and a" nonpotentiated myorelaxingdrug'respectively, was measured in mice.
several groups of mice, each group comprising 1Q animals, were injected with diiferent doses of methocarbamol, alone and potentiated with [u(p-chlorophenyl)-a-phenyl]- 4-pyridyl-carbin0l.

The data tabulated above show that the righting reflex (r.r.) is absent for a relatively great length of time, when the myorelaxing drug is potentiated, whereas the nonpotentiated drug give times of absence of lighting reflex which are considerably shorter.
These preliminary pharmacological data are believed to be a suificient showing of the potentiating effect of oz-[ (p-chlorophenyl) -a-phenyl] -4-pyridy1-carbinol towards the myorelaxing activity of Methocarbamol.
