4.2 Absorption, Distribution and Excretion

TOPICAL & IV APPLICATIONS OF (14)C LABELED 2-ETHYL-1,3-HEXANEDIOL WERE MADE TO HAIRLESS DOGS. AFTER TOPICAL ADMIN, EXCRETION WAS NEARLY COMPLETE AFTER 4-5 DAYS. RADIOACTIVITY LEVELS IN BLOOD SAMPLES WERE TOO LOW TO BE ACCURATELY MEASURED. WITHIN 48-96 HR AFTER APPLICATION ONLY SMALL AMT OF RADIOACTIVITY WAS RECOVERED FROM SKIN. RATE OF URINARY EXCRETION AFTER IV ADMIN WAS COMPARABLE TO THAT RECORDED IN HUMANS. IT IS SUGGESTED THAT PERMEABILITY OF HAIRLESS DOG'S SKIN MAY BE QUITE SIMILAR TO THAT OF HUMAN SKIN.

PMID:7441113 REIFENRATH WG ET AL; J ENVIRON PATHOL TOXICOL 4 (1): 249 (1980)

AN IN VITRO APPARATUS WAS USED TO STUDY SKIN EVAPORATION & PENETRATION OF MOSQUITO REPELLENTS. IN VITRO REPELLENT DURATION, CALCULATED FROM REPELLENT EVAPORATION RATES, WAS COMPARED TO IN VIVO DURATION AT THE SAME DOSE (0.3 MG/SQ CM) TO ASSESS VALIDITY OF THE MODEL. IN VITRO DURATIONS FOR 2-ETHYL-1,3-HEXANEDIOL CORRELATED WITH IN VIVO DURATIONS, ALTHOUGH IN VITRO DURATION WAS LONGER THAN IN VIVO DURATION.

PMID:7131265 REIFENRATH WG, ROBINSON PB; J PHARM SCI 71 (9): 1014 (1982)

PERCENTAGE PENETRATION OF 2-ETHYL-1,3-HEXANEDIOL WAS DETERMINED ON HAIRLESS DOGS AT 4 UG/SQ CM. MEAN PERCENTAGE PENETRATION INCREASED SLIGHTLY WITH INCREASED DOSE OF 2-ETHYL-1,3-HEXANEDIOL, BUT NONE OF THESE CHANGES DIFFERED SIGNIFICANTLY AT THE 95% CONFIDENCE LEVEL.
