piperidylmethyD-phenothiazlne United States Patent ATARACTIC COMPOSITION COMPRISING -(l- METHYL-3-PIPERIDYLMETHYL) PHENOTHIA- ZINE AND 10-(3-DIMETHYL-AMINO-PROPYL)-2- CHLOROPHENOTHIAZINE Henry Angus Bowes, Baie dUrfe, Quebec, Canada, as-
signor to Warner-Lambert Pharmaceutical Company, Morris Plains, N. J., a corporation of Delaware No Drawing. Application September 21, 1956 Serial No. 611,350
6 Claims. (Cl. 167-65) as well as to the desirable ettects that such drugs have produced in patients receiving them. Only too frequently does optimism of early trials give way to cautious restraint in later trials by reason of undesirable side reactions produced by such drugs. Among the drugs which have been found eltective in the management of many types of mental illness are the following two drugs identified by name and structural formula:
Mepazine or 10- (1-methyl-3- nized that some of these complications are due to the sympatholytic character of the drug.
It is an object of this invention to provide an ataractic composition which affords the beneficial efiects of Mepazine and Chlorpromazine, inmentally disturbed patients, but which does not produce the undesirable side reactions characteristic of Mepazine and Chlorpromazine. Further objects of this invention will be apparent from other disclosures set forth hereinbelow.
2,872,376 Patented Feb. 3, 1959 lCQ whereof are described hereinbelow. The said twodrugs may be used either in the form of the free base or as nontoxic acid-addition salts thereof such as the hydrochlorides, sulfates, acetates, lactates, succinates, malates and the like.
In accordance with this invention there has been found, surprisingly, that Mepazine and Chlorpromazine act synergistically in the composition of this invention. Thus the tranquillizing effect of the said composition was found to be consistently greater than might be expected from a mere summation of the tranquillizing etfects due to the two component drugs individually in the same dosage for eachas was used in the said composition, and also consistently greater than the tranquillizing efiect obtained when either of the two drugs was used alone in a dosage equal to the sum of the dosages of the said two drugs in the said composition. 'A further advantage of the composition of the invention is that the two drugs thereof are mutually antagonistic to each others complications. Further, the coadministration of the two drugs obviated the instances of the separate use of Mepazine in those patients, usually those of asthenic build, who are helped more by Chlorpromazine than by Mepazine, and conversely of the separate use of Chlorpromazine in those patients, usually of pyknic build, who are helped more by Mepazine than by Chlorpromazine. The composition of this invention may contain Mepazine and Chlorpromazine in various ratios. A predominant proportion of Chlorpromazine is indicated for use in the asthenic who is prone to feel anxiety at an adrenergic level. Mepazine would be used-in a much higher proportion than Chlorpromazine in the pyknic whose anxiety is frequently manifested at a cholinergic level. The proportion of the two drugs, in the composition of this. invention, may be adjusted to suit the individual patient after an appraisal of where this patient lies between these extremes. In most cases compositions containing equal parts of Mepazine and Chlorpromazine have been found to be broadly effective.
The administered dosage of the composition of the invention in the form of tablets, capsules, elixir and suppositories, varies broadly and may be adjusted to the requirements of the individual patients. In general, patients are started *on a total dosage of 100 to 300 mg. of the active ingredients administered three times daily whereafter the dosage is adjusted up or down until the desired degree of tranquillization is obtained. Usually the adjusted dosages for various patients fall within the range to 900 mg. daily. By the parenteral route the dosage range is usually 50 to 200 mg. daily.
Although the exact mechanism of action of the ataractic composition of this invention is not known, it is believed that the said composition works centrally by depressing the outflow of both the sympathetic and parasympathetic nervous systems, thus reducing the physical concomitan-ce of anxiety. The patient is freed from his sweating, tremor palpitations and gastrointestinal upset and thus is able to take a more objective view of his emotional problems with which he may now cope with the aid 'of psychotherapy. In addition his drive is sufiiciently reduced so that the fear of losing self-control is markedly diminished. Y
