  • Patent number: 5767159
    Abstract: The invention relates generally to a method of increasing creatine supply depot of mammals having no disorders in the creatine metabolism, viz. Healthy, thereby increasing muscular strength, shortening the period of re-establishment of phosphorous compounds in energy after work and increasing the body of the muscles. This is achieved by the administration of creatine to the mammals in an amount of at least 15 grams, or 0.2-0.4 g/kg body weight or preferably about 0.3 g/kg body weight, per day for at least 2 days. The invention describes the use of creatine for the manufacturing of a preparation to increase the muscle performance ability in an amount which supplies a daily dose as stated above and a method.

  • Patent number: 5750559
    Abstract: The antireactive-antiasthmatic effect of inhaled loop diuretics is potentiated by the use of a combination of a loop diuretic and a non-steroidal anti-inflammatory drug as an inhalant for combating asthma. The use of a cyclooxygenase inhibitor as the non-steroidal anti-inflammatory drug is preferred, particularly preferred is the use of furosemide as the loop diuretic. Especially advantageous is the use of piretanide as the loop diuretic. Particularly preferred is the use of acetylsalicylic acid as the non-steroidal anti-inflammatory drug.The most remarkable finding of this invention is the excellent and steady protective effect afforded by the combination of the two drugs in the patients with late asthmatic reactions between the seventh and eighth hour, when the effect of treatment with either drug alone appeared to be progressively decreasing.

  • Patent number: 5739365
    Abstract: A method is disclosed for preparing ammonium hydroxyalkyl sulfonate by a process of reacting ammonium bisulfite and alkylene oxide wherein the pH is maintained at a relatively low value throughout most of the time of reaction of ammonium bisulfite and alkylene oxide in order to minimize the quantity of impurities, e.g. alkylene glycol and alkanolamine, in the ammonium hydroxyalkyl sulfonate. Ammonium alkanoyl alkyl sulfonates prepared by reacting such ammonium hydroxyalkyl sulfonates with fatty acids form aqueous solutions which are clear at ambient temperatures, and thus are useful as surfactants in clear liquid products.
