  • Patent number: 4990513
    Abstract: The antihypoxic drug with verebroprotective and hepatoprotective action contains piracetam and orotic acid or their pharmaceutically tolerable salts in a weight ratio of from 500:1 to 1:2. This combined drug is administered for the treatment of acute and chronic diseases and exogenic intoxications in daily doses respectively from 0.150 to 50 g and from 0.030 to 0.30 g of both components. The synergistic effect of the combination is shown in the antihypoxic action as confirmed by clinical data. The drug can be administered orally or parenterally. The oral therapy comprises tablets, capsules, pills, solutions and emulsions and is applied in slight forms of exogenic intoxications, whereas the parenterally therapy is suitable in case of severe diseases and acute exogenic intoxications leading to complex injuries of the organism.

  • Patent number: 4806548
    Abstract: This invention relates to an improved anti-ulcer composition for prophylaxis and treatment of stomach and duodenum ulcers, including stress ulcers. The composition provides potent anti-ulcer activity with a dramatic reduction in toxicity and harmful side effects. The composition comprises a histamine H.sub.2 antagonist based on a guanidine derivative, preferably [N-cyano-H'-methyl-N"]-2(4-methyl-imidazolyl)-methylthio-[ethylguanidine]; and at least one 4-phenyl-tetrahydroisoquinoline antidepressant, preferably the [+] isomer of 4-phenyl-2-methyl-8-amino-1,2,3,4-tetrahydroisoquinoline hydrogen maleate. The composition may also contain a spasmolytic agent, preferably 2-metoxycarbonyl-4-(beta-piperidino ethyl) -metoxycarbonyl-4-(beta-peperidinoethyl) benzophenone. The ratio of antagonist to antidepressant ranges from 2:1 to 60:1, and the ratio of their sum to the spasmolytic agent, when used, ranges from 2.2:1 to 42.5:1.

  • Patent number: 4704468
    Abstract: This invention relates to biologically active esters of 0(2,6-dichlorophenylamino) phenylacetic acid and a method for their preparation. The inventive esters have the formula ##STR1## wherein R represents a hydroxyl group or the radical ##STR2## and n is an integer from 10-450. The molecular mass of the inventive compounds ranges from 700-30,000, as determined by the vapor pressure method. The inventive compounds may be prepared by reacting 0(2,6-dichlorophenylamino) phenylacetic acid with polyethyleneglycols having the formula HO (CH.sub.2 --CHO.sub.2).sub.n H, where n is as defined above, in the presence of an acid and while heated in an inactive solvent. The inventive compounds exhibit a high antiphlogistic activity, but are much less irritating to the stomach mucosa then the prior art compounds.

  • Patent number: 4666918
    Abstract: The invention relates to tetrahydroisoquinoline derivatives of the Formula ##STR1## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are each selected from the group consisting of a hydrogen and a hydroxyl group. These derivatives are useful in tocology (obstetrics).Administration of the inventive compounds induces relaxation of uterine muscles, a property that is particularly useful in cases of second trimester miscarriage, premature birth up to the 37th or 38th week of pregnancy, and during delivery. The compounds are especially useful from the onset of labor up to delivery of the newborn's head, a period which is often accompanied or complicated by frequent, violent, uncoordinated contractions of the uterus. The compounds are also useful in obstetric and gynecological operations, such as a hysterectomy, surgery for acute placental insufficiency, etc.
