OXYQUINOLINE SULFATE ... IS ... USED ... IN TREATMENT OF ATHLETE'S FOOT, VAGINITIS, & AS A GARGLE, EYEWASH, NASAL DOUCHE, & IN HEMORRHOIDAL PREPARATIONS ... /OXYQUINOLINE SULFATE/

Osol, A. (ed.). Remington's Pharmaceutical Sciences. 16th ed. Easton, Pennsylvania: Mack Publishing Co., 1980., p. 1111

/OVER THE COUNTER/ HYDROXYQUINOLINE IS 1 OF 4 ANTIFUNGAL AGENTS RECOMMENDED FOR ACTIVE TREATMENT OF FUNGUS ASSOCIATED WITH DIAPER RASH & PRICKLY HEAT IN BABIES. /HYDROXYQUINOLINE/

SADIK F; J AM PHARM ASSOC NS10 (JAN): 19-24 (1970)

8-HYDROXYQUNIOLINE SULFATE INHIBITED FORMATION OF ARTIFICIAL CALCULUS IN VITRO & RAT CALCULUS IN VIVO. IN RATS, IT PREVENTED CALCULUS FORMATION WHEN APPLIED BY SWABBING OR BY INTRAORAL INSTILLATION. IN DOGS, FORMATION OF DENTAL PLAQUE WAS INHIBITED 33 TO 98% IN COMPARISON TO PLACEBO. ALSO, 25 TO 58% OF ESTABLISHED PLAQUE ACCUMULATIONS WERE REMOVED, WHEREAS PLACEBO REMOVED 2 TO 22%.

5.3 Absorption, Distribution and Excretion

Route of Elimination

Oxyquinoline is excreted in both the primarily in the urine with some in the bile.

IN RATS /MALE, DONRYU STRAIN, IV INJECTION/ 8-HYDROXYQUINOLINE WAS METABOLIZED TO GLUCURONIDE & SULFATE CONJUGATES. MORE 8-HYDROXYQUINOLINE GLUCURONIDE WAS EXCRETED IN URINE THAN 8-HYDROXYQUINOLINE SULFATE CONJUGATE. ONLY THE GLUCURONIDE CONJUGATE WAS EXCRETED IN BILE.

PMID:409509 KIWADA H ET AL; CHEM PHARM BULL 25 (7): 1566-73 (1977)

8-HYDROXYQUINOLINE WAS METABOLIZED TO GLUCURONIDE & SULFATE CONJUGATES AFTER IV ADMIN IN RATS /MALE, DONRYU STRAIN/. THE GLUCURONIDES WERE EXCRETED IN BILE & URINE, BUT THE SULFATES WERE EXCRETED EXCLUSIVELY IN THE URINE. UNMETABOLIZED FORMS WERE ONLY SLIGHTLY EXCRETED.

PMID:96945 SAWADA Y ET AL; CHEM PHARM BULL 26 (5): 1357-63 (1978)

5.4 Metabolism/Metabolites

In the urine, 60% of the dose is excreted as glucuronide conjugates and 23% of the dose as sulfate conjugates. In the bile, 9% of the total dose is found as glucuronide conjugates.

IN RATS /MALE, DONRYU STRAIN, IV INJECTION/ 8-HYDROXYQUINOLINE WAS METABOLIZED TO GLUCURONIDE & SULFATE CONJUGATES.

PMID:409509 KIWADA H ET AL; CHEM PHARM BULL 25 (7): 1566-73 (1977)

8-HYDROXYQUINOLINE WAS METABOLIZED TO GLUCURONIDE & SULFATE CONJUGATES AFTER IV ADMIN IN RATS /MALE, DONRYU STRAIN/. UNMETABOLIZED FORMS WERE ONLY SLIGHTLY EXCRETED.

PMID:96945 SAWADA Y ET AL; CHEM PHARM BULL 26 (5): 1357-63 (1978)

5.5 Mechanism of Action

The mechanism by which oxyquinoline exerts its biocidal effect is unknown.
