4.1 MeSH Pharmacological Classification

Anti-Bacterial Agents

Substances that inhibit the growth or reproduction of BACTERIA. (See all compounds classified as Anti-Bacterial Agents.)


Coccidiostats

Agents useful in the treatment or prevention of COCCIDIOSIS in man or animals. (See all compounds classified as Coccidiostats.)


4.2 Absorption, Distribution and Excretion

WHEN GIVEN ORALLY, CONSIDERABLE PERCENTAGE IS EXCRETED IN FECES, INDICATING THAT PHENYLARSONIC COMPD ARE POORLY ABSORBED BY INTESTINAL TRACT. THAT PROP WHICH IS ABSORBED, HOWEVER IS APPARENTLY EXCRETED RAPIDLY BY THE KIDNEYS.

There are only a few reports on the excretion of arsenic in the milk of animals. The arsenic level in cow's milk did not incr with the blood concn when the cows were fed methylarsonic acid or dimethylarsinic acid... . However, the milk arsenic levels did incr when cows were fed arsanilic acid or 3-nitro-4-hydroxyphenylarsonic acid (1.6-3.2 mg As/kg bw)... .
