Abstract:
Methods and formulations are provided for treating migraine and other acute pain episodes using diclofenac, and formulations of diclofenac that provide both rapid and sustained relief from acute pain. Methods and formulations are also provided for treating symptoms that often accompany migraine and acute pain such as photophobia, phonophobia, nausea and vomiting.
Abstract:
New pharmaceutical compositions for oral use containing Diclofenac together with alkali metal bicarbonates in amounts of from 20 to 80 by weight with respect to Diclofenac are described. These compositions are entirely palatable and free from any unpleasant taste or other side effects; in particular, these formulations permit to obtain in human patients higher Cmax of the active principle and shorter Tmax together with a lower coefficient of variation.
Abstract:
The L-arginine salts of the mercaptoethansulphonic acid are active in the therapy of the bladder carcinoma and in the therapy and prevention of the cistinic kidney calculi.The saline derivatives with basic aminoacids and their alkyl esters are moreover devoid of side effects.The latter derivatives are prepared by reacting, in aqueous or aqueous-alcoholic medium, equimolar amounts of mercaptoethansulphonic acid, just prepared from an organic or inorganic salt thereof, and of the desired aminoacid.
Abstract:
For the preparation of compounds such as ranitidine, niperotidine and cimetidine a urea of the formula:R.sub.1 --NH--C--NH--(CH.sub.2).sub.n --SD--S--(CH.sub.2).sub.n --NH--C--NH--R.sub.1 (I)which is synthesized by reaction with a compound of formula ##STR1##[H.sub.2 N--(CH.sub.2).sub.n --S--] (IX)is converted in a first stage into the corresponding bis-carbodiimideR.sub.1 --N.dbd.C.dbd.N--(CH.sub.2).sub.n --S--S--(CH.sub.2).sub.n --N.dbd.C.dbd.N--R.sub.1 (II)by reaction with triphenylphospine and bromine in the presence of a strong base and in a second stage the diimide thus obtained is reacted with nitromethane or a saline derivative of the cyanamide.The product thus obtained is reduced at the disulfide bridge obtaining a compound of formula: ##STR2## which is reacted with: ##STR3## to obtain ranitidine and niperotidine or cimetidine respectively depending on whether the first or the second of the described reactants is used.

Abstract:
The invention relates to esters of 3-hydroxy-quinuclidine with phenoxycarboxylic acids, and their salts having general formula: ##STR1## wherein R.sub.1 represents H,CH.sub.3, and R.sub.2 represents H, Cl,Br or a radical of an acid of the group comprising oleic, pivalic, nicotinic, clofibric, pyridineacetic and teophyllineacetic acid.The compounds of the invention jointly show hypocholesteremizing and hypotriglyceridimizing activity, combined with other therapeutically interesting properties, such as beta-blocking, diuretic, anti-inflammatory activity.The invention furthermore relates to the pharmaceutical compositions containing the compounds of the invention as the active ingredients.
Abstract:
The amide derivatives of p-isobutyl-phenyl-propionic acid, having general formula ##STR1## wherein X is the radical of a substituted amine, of the group comprising lysine, metatrifluorotoluidine, glutamic acid and aspartic acid, show a good anti-inflammatory activity, accompanied by favourable side properties. For the preparation of the compounds of the invention, the p-isobutyl-phenyl-propionic acid is chlorinated, and the chlorinated derivative is reacted with the proper substituted amine.
Abstract:
The invention concerns novel piridoxine derivatives of the general formula: ##STR1## which show anti-inflammatory activity and moreover may show, although not necessarily, also analgesic and/or anti-pyretic activity.
