摘要:
The invention relates to the new 2-hydroxyethyl-trimethyl-ammonium salt of 1-ethyl-3-carboxy-4-oxo-6,7-methyl- erseriioxy-1,4-dihydroquinoline having ureterodisinfecting ac- tirvity, which is prepared by reacting 1-ethyl-3-carboxy-4-oxo--6,7-methylenedioxy-1,4-dihydroquinoline with the aqueous or ethanolic or with the aqueous-ethanolic solution of 2-hydroxyethyl-trimethylammonium hydroxyde. The new salt is water-soluble and well resorbed after oral administration. Thus, it is useful both in the human and the veterinary medicine.
