  • Patent number: 5225413
    Abstract: A pH-neutral aqueous solution of a quinolonecarboxylic acid of the formula ##STR1## in which R.sup.1 represents halogen, C.sub.1-4 -alkyl or C.sub.2-4 -alkenyl,R.sup.2 and R.sup.3 represent hydrogen, C.sub.1-4 -alkyl, or together the adjacent nitrogen atom form an optionally substituted morpholine or piperazine ring,R.sup.4 represents optionally substituted C.sub.1-4 -alkyl or C.sub.3-6 -cycloalkyl,X represents --N.dbd.or --CR.sup.5 .dbd., andR.sup.5 represents hydrogen, halogen, OH or C.sub.1-4 -alkyl, orR.sup.4 and R.sup.5, together with the C and N atoms position between them, form a saturated 5- or 6-membered ring which can contain other hetero atoms and which is optionally substituted,the solution containing calcium ions in at least an equimolar amount relative to the quinolonecarboxylic acid and having a pH between about 6.5 and 7.5.
    Type: Grant
    Filed: November 30, 1990
    Date of Patent: July 6, 1993

    Inventors: Arundev H. Naik, Herbert Voege
  • Patent number: 5152986
    Abstract: Known antibacterial quinolonecarboxylic acid derivatives such as ciprofloxacin are administered to animals in their food in the form of weak cation exchangers loaded therewith. The taste is much improved and the animals accept the material more readily.

  • Patent number: 4772605
    Abstract: Improvement in the parenteral administration of a carboxylic acid of the formula ##STR1## in which X is N, C--H or C--F,Z is O or Ch.sub.2,R.sub.1 is hydrogen, methyl, ethyl or .beta.-hydroxyethyl,R.sub.2 is cyclopropyl, 2-fluoroethyl or ethyl,R.sub.3 is hydrogen or methyl, andR.sub.4 is H or methyl,is achieved through the administration of the basic salt of the acid (I, II). Surprisingly the basic salts are suitable and stable.

  • Patent number: 4764529
    Abstract: The invention relates to pesticidal (e.g. pyrethroid) pour-on formulations prepared on an aqueous basis; and also includes the method of combatting pests and parasites of warm-blooded animals, particularly acarines and insects by applying said pour-on formulations to the animals.

  • Patent number: 4737520
    Abstract: A water-soluble pesticidal formulation approximately comprising in grams per liter 10 to 500 of at least one pyrethroid, 10 to 200 of a non-polar solvent having a solubility in water at 20.degree. C. of 0.01 to 15 g/liter, 20 to 500 of at least one non-ionic emulsifier, 5 to 250 of at least one anionic emulsifier, up to 300 of a solvent having a solubility in water at 20.degree. C. of at least 30 g/liter, up to 5 of a dyestuff, up to 50 of auxiliaries and up to 900 of water. The formulation will dissolve in water to give clear solutions.
